As the title says. With premium being 70-80 cents higher than regular where I live. Im curious if anyone runs 87 vs 93? Any performance issues?

I do not run anything except for 93. I would assume that you can "safely" run a lower octane if you don't care about it retarding the timing or limiting the boost. You're going to knock if you push the car running lower octane and if you knock the car is going to pull power.... or detonate.... hopefully pull power....

I paid for 295ft/lbs and want it so i run esso's 94 octane (up to 10% ethanol)... A pain as 91 is all i can get in my home town and surrounding areas. I bring back 100 liters once or twice a month with me in the truck (work in the Toronto area).

The 80-90 cents extra is insane though! Up here 93-94 will run you 40-50 cents more than 87 octane will

I'd be afraid to do an even 'semi' hard pull on 87 octane in the 2.0T!

Edit: forgot to take the canada/us thing into consideration... You guys do WAY better on gas prices than us suckers up here in the frozen tundra lol!
Sorry, Petro Canada has the 94... Esso I'm not so sure

No way. 93 only.

91 is max where i live thats all i use

for people that can only get less than 93oct, is octane booster an option? never used it, just wondering?

Never used it myself and don't know enough about it to know if it has long term effects on any parts. That being said my old man has used a bottle per fill up for years in his '97 bwm 318 which has been running a custom turbo kit the whole time with no issues to speak of.

Why is your premium gas so much more expensive than regular?

I'm sure there is some blog or forum post detailing it somewhere in the Internet but I'm too lazy to look it up at the moment. My assumption would be that it might reduce power density of the fuel and if left to sit for long enough might separate into an uneven mixture. Those are my guesses.

They're only good up to a point also as the chemicals used (mainly tortulean... I doubt i spelled that right) increases the octane for sure, but also promotes a lazy burn, ie. How fast the flame advances through the combustion chamber; Dsport had an awesome article about it... It might be in their online tech area

If you're only using a bottle per fill up though, its not an issue

I think it's Toulene? I may be wrong.....

Good guess though.....

Lol, thats the stuff, cheaper than buying the actual 'octane booster' also

Yup, very true
