Fuel Grade, my first time with Audi

Re: Fuel Grade, my first time with Audi
..."Volvo cars call for "premium fuel [91 octane or better] for optimum performance and fuel economy," said Wayne Baldwin, product/segment manager for the S60/S80. "However, there is absolutely nothing wrong with using 87 octane, as the knock sensors and engine management system 'protect' the engine from knocking."
If you chip then forget about using improper fuel as you'll have knocking and ultimately do harm to your engine if you push it.

It makes no sense to go against something that was engineered and developed for years and complain why **** knocks or breaks after.
Always follow what the manual says, its there for a reason.
Hah funny though, soon people will start fuelling up with 87 and use octane booster and think they get the same performance and use cooking oil to dilute synthetic to save a bit of cash in the short run lmao
Its fuels 101 bro *Fist pumps*

Re: Fuel Grade, my first time with Audi
If you want to run 87, on a stock 2.0T, it will be fine.
You will lose performace and gas mileage will depend on your driving style. If you putt around like an 85 year old grandma, you might even see an increase of 1-2 mpg's, but if you drive it even a little "spirited" you will see a drop.
The only way to tell if it's good for you or not is to actually run a few tanks and see what happens.

They use different octane scale. so thats not exactly true. I cant remember the scale or the names but in europe 98 octane ( i think) = north american 91. The octane number is is set by the oil company and as i said the one in europe uses different scale but its exact same in the end.

I bought my first '98 A4 1.8t last year. First month or so I used 91, like it says on the gas cap door. Then, switched to octane 87, thinking that all octane level gas is the same. After about my second fill up with 87, the car started pinging really bad. Performance was also affected. Never used 87 after that. Always 91.
