Hey, just quick question I didn't look anywhere else 1st, so don't beat me up.

Local gas stations don't have e85, but now they are carrying 90oct non-ethonal.

My friend has a stock 04 A4 1.8T and ran his tank empty and decided to try some. Said the car ran like crap. Didn't boost right didn't pull, it was horrible. He was glad to have only spent $20 on gas that was $4.78 a gallon.

Now my dad, loves it for it 89 Yamaha 700cc bike cause non-ethonal is all the engine builder said to use after his dual carbs needed a rebuild to keep his bikes carbs clean and was only really only able to use the fuel cause they had it 35 miles from me down by his job but wasn't worth a solo trip for some.

I'm in Tampa Bay Florida area.

1.) Why did my friends car run like crap on it he always runs 93 no questions asked, but wanted to try it without researching?

2.) Any reason to use it or care about it for my 2.7T?


Thanks

I understand the lower octane. Understand the results. But was it the lower octane or the non-ethonal?

Ethanol is used as an octane booster.

I'm so glad the pump gas in the UK starts at 95RON ,I can get 99RON At my local supermarket :-)

95 is crap, stay away from it if you gonna tune your car.
