In this article https://www.cars.com/articles/whats-the-best-compact-suv-443017/ it mentions premium gas needed for Tiguan to get the rated horsepower. Is this true? I haven’t come across anyone saying this in every video and article I’ve read about the 2022 which is most of them.

It’s not a link it’s a screen shot, but if you want the link it’s below:
In California at least, it’s very hard to get ethanol free gas, my nearest station is 200mi away For ethanol free. I can’t comment on other states obviosuly.
Also the ethanol content will/must be printed on the gas pump, have a look next time you fill up.
Regular, TOP TIER gas is all you need for the Tiguan, at least for the 2022, inside the filler cap tells you the AKI needed, anything more you are free to purchase, but it’s your money and how you spend it is your business. Just be aware you do not NEEED premium And it won’t unlock any extra horse power, unless your engine is modified. (Ignition timing advanced by an after market tune, higher compression ration, aded a turbo or has been super charged.)

Thank you. USA site. Canadian site does not state that. Ethanol free is getting harder to find.

One of the reasons I bought my 19 SEL is because you can run regular unleaded in it (per the manual) as long as it has a minimum 87 octane rating. Been doing just that for over two years and no complaints. According to every expert I’ve read on the subject premium gas is a waste of money if you can run regular. Many do recommend running premium on higher mileage cars to prevent pinging.

@OhioSpyderman . yes i do work for VW . but giving instructions on how to do coding is against my job policy. i can explain some misleading information running all over the internet. and regarding your experiments. i would suggest using obdeleven for this type of modifications. Just remember to never wipe clean any module using obdeleven. always do backups before doing long coding. If you do full wipe on module it will rrequire ODIS to bring module back.

Running a higher octane of gas than your engine was designed to run on, will produce no more horse power of any significance, if at all. Any butt dyno figures are most likely nothing more than a placebo effect.
Just run the pump gas the engine is designed for, any more you are mostly wasting Your money. Havign said that, it’s your money, so if it makes you feel better, then go for it!

I own a 2022 Tiguan se and on the fuel door says 87 octane which is regular unleaded
Premium won’t make a difference

Correct, same here, on 87 octane and if at high altitude you could get a bit of engine knock due to the altitude. In which case the ecu will retard the ignition to prevent the knock. In this scenario going to higher octane could restore a little performance by preventing the ECU from needing to do so.
But under normal circumstances higher octane/premium may only net you the benefit of potential additional detergents in the fuel.

There is car scanner app that will give you better insight on what happens when running higher octane fuel. if someone needs more help figuring out how different are some charts 87 vs 90+ octane i will be happy to assist.

Wait wait I have been using 87 and have no issues with the vehicle’s responsiveness or performance, but if 91 is actually the optimal fuel to use can I just start using it or does it not even matter since I’ve now been using 87 for ~7700 miles. I would love a technical explanation of what changes in engine operation with 91 vs 87 and the best way to migrate over to using 91, do I just let it get pretty low and then fill it up, I don’t want to «shock» my engine so to speak.

To comply with emissions regulations VW has had to tweak the vehicles down significantly in my opinion.
Hasn’t every manufacturer faced the same thing. I miss the good old days.
My 1984 Volkswagen GTI was a pocket rocket with minor mods (larger throttle body). No special oil at $170 CAD per oil change. End reminiscing. lol

And regarding aftermarket air intake. any type that is exposed under the hood (bonet) and can suck on hot air instead of using rooted channels under closed hood. will kill your power and air density. will make your turbo producing more heat and intercooler will have harder time bringing temperatures down. Air density is very important with turbo charged engine.

While I fully understand and appreciate what you said, from 20+ yrs. of driving a TWIN TURBO (320 HP stock) AWD vehicle (see below) with a K&N FIPK, I saw zero issues with under hood heat.
As you can see, the engine bay on my Spyder was much more «condensed» than my Tiguan.
I’m almost 65, and have little interest in «racing» the vehicle, just looking for a little more pleasurable (read NORMAL) every day driving experience.
The «lag» perceived by almost all of the vehicle owners is not a myth.

Well I always use ethanol free premium usually from Costco. The engine is designed for premium though you can run regular fuel [emoji618]
As far performance, meh not sure on that. More folks will chime in. [emoji2]
In NA regular is in the manual.

Totally agree! I’ve been working on cars since the late 70’s and even took auto-shop in HS but didn’t learn much as it was just a hang out period. Remember using premium only and never had a problem with plugs or rough running on any of the new and used cars we’re ever owned. Runs quieter, smoother, peppier and more responsive. Depending on the car a couple 2-3 mpg more so offsets the additional price. While in CA it was either Chevron or Costco, Chevron being the best fuel available or ever used. Now run Costco exclusively.

Interesting you mentioned Canadian manual. Is cars.com from Canada. From this link in the US media guide https://media.vw.com/en-us/press-kits/2022-tiguan-press-kit if you scroll down to right before the gallery there is a pdf link for technical specs and when you open that it says regular gasoline

I have never heard that our MK2s require premium. Have no idea where the author got that info.
You may get some extra detergents with the pricier fuels, but all you really need to do is avoid knocking. Buy from a reputable merchant.

I actually noticed a bit of a difference after my first fill up (with premium), with my 2022 Tiguan. The fuel economy was noticeably better — I was told by a little birdie that the dealership I bought my car from always fills their cars with the lowest grade of fuel. But the increase in fuel economy could be from the engine breaking in, so who knows

Is there noticeably more power with premium too? Remember I started this thread based on the cars.com link saying to get the horsepower numbers advertised you need premium fuel.

I ran my 2019 SE for 70K miles on 85 octane (I’m in CO) with zero engine problems and never missed a beat.
I’ve been running my new 2022 SE-R on mid-grade 87 or premium 91. My butt-meter says if feels more responsive than the 2019 but I know VW has refined the software too.
Fuel economy is just as good or perhaps a tick better but I don’t yet have enough data to support that statement.

It is true for all cars that have over 9.5:1 compression, that do not have direct injection into the cylinder.
That is because with high compression, you will get pre-ignition piston knock with low octane fuel, unless the ignition is retarded.
And when the ignition is retarded, you not only lose power, but spend more on gas.
So then buy premium, it saves money.

2016 Golf S manual (1.8 L) from the manual: minimum recommended octane 87 RON
Running 87 octane is not going to do any harm to the engine, but at full throttle/peak power the detonation sensor(s) will limit timing advance so you won’t get rated hp. Cruising hp/mpg is unaffected by 87.
I compromise and run 89 (in CA).

Running good quality 87 octane low elevation or Colorado or similar 85 octane are fine with calibration values for NA. now regarding going higher octane quality fuels will reward you with less timing pulling. . less misfires. more time studying in Budack cycle ( you need to learn how this is used and when). max output. like torque will still be limited by ecm irrelevant to fuel octane. i can explain in more detail some scenarios with so many things happening regarding when engine is running under various loads and temperatures and how fuel affects other areas of powerpack efficiency.

Picked the new 2022 SEL R Line last month from the dealership, course they filled it up with a full tank of 87, felt like the car was unresponsive, dull. The first chance I got, filled her up with 91 from Exxon. So much more responsive. I would recommend 91. Fight me.

Switching from lower to higher octane is safe. irrelevant on fuel tank level. ECM also have ability to read ethanol content up to certain degree. to what changes you will have to post some graphs from apps like car scanner ot factory tool ODIS so i can explain what is happening regarding higher octane quality fuel. High elevation like CO are ok using 85 octane. ECM values for boost always take in to account a barometric pressure at the given location.

Irrelevant at any level.

Ne, není.

Octane and fuel quality are two completely separate things. You can put addatives in crappy fuel to raise octane. and a very pure, high detergent fuel can have low octane. They are not related in any direct way. Marketing and cost are the only reasons higher octane fuels tend to have more detergents.
High elevation like CO are ok using 85 octane. ECM values for boost always take in to account a barometric pressure at the given location.
The car is very aware of its operating parameters: temperature, humidity, station pressure, incline, etc and will always attempt to make as much, and the same for any fuel, amount of power for any operating parameters.

Are we to assume, based on your screen name that you are indeed a VW Engineer (of some sort)?
If so, you have to know we are all eager to hear what you have to say.
I am a retired Engineer myself. I was a controls Software Engineer working with 8 bit to ARM processors.
But honestly, nobody wants to hear about that.
What most here want to know, is how can we make our vehicles more enjoyable to drive.
Be it adding electrical stuff (hardwired dash cams, radar detectors) to wondering what a change in fuel octane might bring.
I understand that graphs, data and maps can tell you a LOT about what’s happening when you change something.
But I think that most here would just like to know what type of benefits (or detriments) they can expect.
Kind of when I asked you in the Throttle Lag thread about using long coding to change a couple of bits.
Instead of telling me. Oh, bit 0 is for XXXXX function and changing it from 1 to 0 will cause this, and changing bit 1 from 0 to 1 will do that.
You gave an answer that told me nothing.
I realize that being an Engineer can sometimes be a tough job, and when someone asks you explain to them (say marketing) what the changes you just made to a customers software will do.
Even though we know exactly what we did, it can be difficult to put it in layman’s terms.
I also realize that when you are actively employed you sometimes CAN NOT tell people «exactly» what changes you’ve made (or what changes they might make will do).
If that is the case with you, I understand. Seriously.
I for one am very glad that you joined, and I look forward to «anything» you can add to ANY thread.
Please don’t don’t take my posting the above anything but friendly conversation.

Volkswagens have been around for quite a while and they’ve greatly evolved over the years. Not only have they grown in size, but they’ve also changed up their fuel requirements as well. If you are the owner of a Volkswagen Tiguan, you may be wondering just what kind of fuel you ought to be using.
According to a Volkswagen sales associate, a VW Tiguan can run on regular gas as long as it’s a newer model. Most turbocharged engines require premium gas to run well, and models that are 2017 and older are typically equipped with those. Models from 2018 and up can run on regular fuel.
If your VW is older than 2018, you’re going to want to fill it up with premium fuel so that it continues to run and perform well. However, there are plenty of newer models that can be filled with regular gas. Here are a few more things you ought to know about VW Tiguans and their fuel requirements.
What Type of Gas Does a Volkswagen Tiguan Use?
Can the VW Tiguan Use Regular Gas?
Some Tiguans require premium fuel and some do not. This will be determined by the model you pick and the age of that model. Some older Tiguans have turbocharged engines that perform better when they’re given high-quality premium fuel. Models from 2018 and newer have been proven to work just fine when filled with regular gas.
Can I put Regular Gas in my 2017 VW Tiguan?
It is advisable not to use regular gas in a 2017 Tiguan. As a sales associate from Volkswagen mentioned, many of Volkswagen’s older Tiguan types perform much better when filled with premium gas. Premium gas can serve as a fantastic lubricant for your vehicle’s engine and help it to run twice as smoothly.
You can use premium gas in your Tiguan if you wish, even if it’s designed to run on regular fuel. According to 4-Wheel Trends, it’s fine to use premium gas in your car because it can increase performance minimally. However, if you can stick with regular gas, you may want to do so. Premium fuel can be somewhat expensive depending on where you live.
At this point, you might be wondering what exactly the difference is between premium and regular fuel. After all, there must be a reason some cars require premium fuel and some do not. Let’s talk about what it is that sets these two types of fuel apart.
What Does Premium Fuel Do?
The differences between premium and regular fuel aren’t significant. High-performance vehicles tend to have more compressed fuel lines and injectors. This means they need a larger amount of octane in the fuel to prevent combustion from occurring at an improper time. Hence the reason most premium cars require premium fuel.
The biggest difference between regular and premium fuels is the octane level. Premium fuel often contains 91-93 levels of octane, while regular gas has levels as low as 87. High octane is required for high-performance vehicles to function as well as it is supposed to do so.
The differences between premium and regular fuel were larger back several years ago. There used to be more detergents and additives in premium fuel that were supposed to clean your engine it runs. It is also supposed to knock down the carbon buildup on your engine, which will help it to run twice as smoothly.
Nowadays, there are plenty of cleaning agents and additives in regular gas that help clean your engine out, though perhaps not quite as well as premium gas does. The bottom line is, the difference isn’t as large as it used to be, so you may want to avoid making premium gas your usual choice unless you have to.
Don’t use premium gas if you don’t have to. However, you shouldn’t skimp on using premium gas if you have a vehicle (such as a 2017 Tiguan) that needs that high level of octane to function well. Using the wrong type of gas in your vehicle could potentially be disastrous and cost you more than you might’ve bargained for.
What Happens If I Use the Wrong Gas in My Tiguan?
So, what will happen if you make a habit of using the wrong kind of fuel in your Tiguan? Anything older than a 2018 Tiguan should be given premium fuel to function well. If you start using regular fuel in a car that needs premium or vice versa, problems could start to occur. The severity of these problems depends on how long you misuse your fuel.
The most common side effect of using an incorrect type of fuel is pre-ignition, better known as engine knock. This is a sound that is produced when your engine tries to combust its fuel at an improper moment. Engine knock may or may not occur until you have put in the wrong kind of fuel several times over a longish period.
Engine knock may not seem like a huge deal at first and you might even find yourself ignoring it. However, if you do that over a long enough period, your engine is going to start burning up and will eventually quit. Then you’ll end up needing to pay for a tow truck as well as whatever it will take to get the engine fixed.
That said, you must always pick the right kind of fuel. Yes, premium fuel can be somewhat expensive, but it will be cheaper, in the long run, to spend a few extra dollars on gas than to buy an entirely brand-new engine for your car. Repeatedly putting the wrong kind of fuel in your car will not do you any favors.
However, it won’t make a huge difference if you do it once or twice. If you arrive at a gas station where premium fuel is not available for any reason, using regular fuel to fill up your car won’t be that big of a deal. Just make sure you’re not making a huge habit out of doing so, or you’re not going to like the results.
