just a vent

but I went out of my way to run the tank down low, then sought out the ethanol free station in town for a fill up

subsequently had the first case of dieseling/run on in 5 years .... since the one time I tried mid-grade gas. Suggests to me the guy selling eth' free is NOT selling the posted octane.

So be wary of where you buy your (eth' free) gas . . . .

my car runs better on true 93+ octane, alc or no alc . . . if I have to replace a seal or a hose, well I guess that's the cost of business.

I could hide the issue with a timing change .... as we did in the 70's when unleaded gas came around.

 

They (station inspectors) need to monitor these stations with eth free or low eth as I had a similiar situation .Yes 93 or better but some of these stations are putting in more eth in their higher octane and getting away with it.

 

This might be of help.
