Here is a new one on me. Today I put gas in my tanK from a place in Portland that I know for sure has E10 and 90% Gasoline.. My car ran tremendously better and was happy. So on the way home today I bought a gallon of Premium from a station that I filled up before. I asked the owner this Question and very carefully:
Q:Were can I buy E85 as I wished we had a station that sells it around here as the Octane is really good for my care and worth as much as E10 Gas?

A:They said we get E85 (also that sometimes its a little old so they get a good deal) from a whole seller when the other prices are too high during the summer and holiday seasons. Also to ask so I could get the right pump. E85 is 2/3 ( instead of $3.00+ a gal, E85 is 2.00 a gal) the price of E10 so do I trust a little station now in this economy, no!!

What can I say. I could tell my car was not running well and the fuel milage was terrible also. It even sounded lean and the timing was off. When I refilled today, my car was very happy. So here is the big deal. That could have toasted my engine and If I had paid a local tuner for an $800.00 tune it would be worthless as it was done with E85 not E0-E10. I could have also done allot of other damage. Almost double the consumption and a very sissy like sound and throttle response and the timing was somehow not as commanded.
You see not just because it is B3601, But anything higher than E10 can cause damage and even wasted money on an expensive tune or a voided warranty. I was pretty sure it was very bad fuel but it did drive me crazy as I think my car is pretty darn fast and it was a sissy mobile.
I am going to try to get a system in my car this winter to know, as I have to much time and money invested to let a gas station or a distributor or an honest mistake even ruin my car.
Thanks SSpdDmon as you are on solid ground with the known part, but you missed an important point because you are honest. Unfortunately that does not mean everyone is or perfect!! We have to find a way on the fly!!
Something to think about.
