YouTube What fuel is best fuel.....

[Thirdgen89GTA]

Interesting bit of videos. They do a dyno comparison of the fuels with tuning. Not very interesting videos, but the dyno data is interesting. I skipped most of it and just kind of went to the excel sheets.

But the end was that VP C85 was the best fuel for power. And that C16 wasn't worth much, despite its insane R+M/2 octane rating. Not saying its the end all be all of comparisons, I'm sure there are situations they missed or just didn't test due to time or scope.

Base car was a C7 Z06.

"E85 at 40% mix." Too bad they couldn't test E85.


And the E85 at 40% and the C85 at 40% comparison has a 15° difference in ambient temps.

Basically they learned that the higher the octane, the more power they can make.

A turbo car would have shown greater differences.
