Well, Chevron premium does have small amounts of Techron in it, and from what I've picked up here and there on BITOG, not only is techron a great cleaner, but it also coats the lining of the combustion chamber. But I dunno, I just picked that up from the nuts on BITOG.Jacko3 wrote:SVTCOBRA:

Anyway, I have been using Chevron premium these past few days and I am surprised at the improved fuel efficiency i am experiencing. What does Chevron have in their fuel that makes the gas that more fuel efficient than the BP premium I have been using for a while? Both, I beleive, now use ethanol. So, why is Chevron premium being consumed much slower than BP premium. If i drive normally, without any WOT, the gas needle almost never moves at all, inspite fo the fact that I have a test pipe which does cause a small drop in mpg.
And, I noticed that our cars are so sensitive to lower octane gas even in small amounts in the gas tank. I used mid grade in my car this week under emergency conditions as there was no gas available, only for less than 5 % of the total amount of gas in the car as I always have at least 85 - 90 percent gas in the tank at all times, and i noticed the engine had a light ticking sound. I burnt off the gas within an hour and filled up again with premium, and the ticking sound was gone. I don't think the VQ engine likes anything less than premium even if it runs well.
