Hey all, I bought my 2008 Tahoe LT a year ago however I did not really drive it in the summer as it was off the road. When I put it on the road in September (Living in New York) I was getting average 12-14MPG with 89octane gasoline.. Had the A/C on most of the time as September was hot.
I decided to put in E85 to test it in the past 2 months on and off. Performance I noticed was not that good as it was harder to start my tahoe and gas went down to about 11mpg. I just let the gas run under 1/4 tank and put in 93.
Question I have is should I see a drastic change in MPG immediately or will this take a few more fillups to see results?
I tried almost everything I could to see even idling mpg which when i reset the average mpg on the dash it should 6-8mpg with the ac running.
I tried everything I read on the forums...
I have my tires at 32psi,i run recirculation,changed air filter, changed all spark plugs, i dont have anything in the truck to weigh it down.
