Thanks
Maybe its time to update this discussion besides its almost end of season here in frozen north. Had a rental 2013 Silverado while having cars repaired from hail damage. Looking at the estimated "Full Tank Range" Using Gasoline 465 miles on 85% ethanol 325 miles ??? Now 4 years later we are finding out many of ill effects of the mix. Contamination, rust and water accumulation especially if left in tanks. ALso the regular of today is not the regular of yesteryear. Old regular when splined on asphalt would eat holes in the pavement. I did locate a station in Montour Falls (down the hill from Watkins Glen) that sells non ethanol it is 87 and $4.57 per gallon vrs 4.10 for the "blend" also had Sunoco race fuel at $9.25 for 110 or 112. Anyhow We bought 10 Gals. to use in car. I'm not sure how much good it will be, but sure hope its better.Hmmm wonder if it would pass "Fuel Sample" test. In view the milage difference I wouls think it has to effect output.
