Can not kill LA......Running on

My 273 was dieseling and it was caused by the ethanol in gas from a very busy & local "Shell" gas station. I usually drive 8 miles farther to a "Gulf" station to fill her up and never had any issues. But when I'm on fumes I usually get a few gallons down the road and I always have a problem!

Hi, just FYI - I run straight E85 & never have trouble w/ dieseling. However, it is very important to get the timing properly adjusted to account for the type of fuel you're running (whatever the composition). Problems w/ E85 are usually: Old, rubber fuel lines (these should be fuel-injection spec), Timing, Carb jetting, dirt related & due to letting the car sit for a few months at a time. However, E10 (10% eth + gas) is fine for normal use.

I use E85 because I get better performance, although the mpg is about 10% lower...but then, the price is about 10% lower. So it's actually getting a 20% discount, because I'm getting 105octane, but not paying the Premium price.

I will bet that the station where you have trouble w/ your gas has dirty tanks or water in them. Usually, all fuel now is mandated to have approx 10% ethanol. So, you're probably getting the same composition, but one station's better than the other at keeping their fuel quality.

Just my 2cents, though.
