Have I been wasting $ on premium for years?

[Hayden]

I heard something about some MK7’s that are supposed to run off 87… to check your fuel tank etc.

Checked mine, it does show 87 but also 91 underneath. From the research I’ve done, in Canada and the US you want to look at the top number, Min (R+M)/2 87.

Is that correct? I’ve been running 91 for 6 years lol.

You can run lower octane fuels, but at the cost of performance and potentially longevity -- don't quote me on that. Idk, I'd rather just pay a little more for premium and have the peace of mind, particularly on FI cars.

If you want to run 87 then buy a Prius.

87 AKI = 91 RON. Different octane units. If the car (stock) says 87 clearly it's ok/safe to run it that way. You lose a bit of top end power is all.

#facts.

Do what you want it's your car and your $. I make sure to get gas from a top tier station (most are) but all I run in the GTI is regular. I don't need the extra power nor the extra $10-12 tank (in CT 93 is $1 gallon more than regular) but I am cheap so I feel better with regular.

Tacoma gets regular, Comet needs 93

Considering how regularly even the stock tune knocks and corrects for it, premium isn't a waste IMO. Yes the car CAN run 87 just fine, but when you get into more extreme situations like higher heat, premium will have less knock and less timing pull.

The only fuel that my MK7.5 has been filled with is Shell 93 octane and I see no reason to change now.
NO POS toyota in my future, thanks diggs24.

My post wasn’t a question of should I run premium or not. It was am I reading/understanding the fuel door sticker correctly?

I’ve been paying for premium for 6 years, so it’s obvious that I’m not trying to save $3 a tank. I am just wondering if this sticker means 87 minimum.

I have done some research and as far as I understand, the sticker says minimum 87.

I know that 2015s require 91 and 2017s require 87, not sure where my 2016 stands is all.

Where did I say that I wanted to run 87? I strictly put premium in this car for 6 years and I put premium in my MK5 for 4 years before that.

By inferring that you've been wasting money. If you want to do something, you're not wasting money. It's money willingly spent.

So to be clear: 87 is perfectly fine based on your fuel door sticker. Your car will run fine on 87, but will probably pull some timing and be down on power here and there. 87 octane = 91 RON

87 is the min. 87 AKI = 91 RON, sticker is for more than just US.

$3? Wow. Here it's typically almost $1 more than regular so $10 is more like it.

If the car I purchased requires 91, or i tuned my car for 91 fuel, I have absolutely no issue putting 91 in. With that being said, if my car calls for 87 by VW engineers, that’s what I’ll run.
I’ve done days of reading and from what I gathered, aside from a false peace of mind, running octane fuel higher than the minimum is giving you no bonuses.

Thank you sir!

Wasn’t to be taken literally. I am inn Canada but after conversions, Regular fuel is $5.79 a gallon and premium is $6.47

So... you do want to run 87?

I'm so goddamn confused by this thread and your responses.
