dsrsf Rookie Author Allentown Posts:3 Points:6,110 Joined:Apr 2009	Message Posted: Apr 7, 2009 2:38:36 PM Ignore dsrsf Report Abuse Is there really a difference in mileage? I have a Shell station that is 5-10 cents more a gallon than my local non-branded that's down the street which stocks E10. Would I be gaining more from getting the Shell versus the no-brand? A link to a study would be nice, too. I'm also going to try my own trial - E10 versus Top Tier (shell is the only brand local).

Some places have E-10 as all three grades and in some places they do not. Where I am the posted signs state up 10% ethanol for all grades so you are never sure if its 10% or not..

Midgrade is cheaper than the Regular. [Edited by: HeavyDuty_cache at 4/18/2009 1:28:10 PM EST]

ajhoier Champion Author Florida Posts:1,065 Points:67,965 Joined:Dec 2008	Message Posted: Apr 13, 2009 10:02:35 AM Ignore ajhoier Report Abuse the topic makes no sense. I've seen "top tier" stations with signs posted, may contain as much as 10% ethanol... It's an environmental thing, I know I've seen some stations advertise "we don't have E-10" on bill boards, so I don't think, or know, if it's mandated here in Florida....but most stations around here have this "filler"...

rayw45 Champion Author New Jersey Posts:7,777 Points:393,800 Joined:Aug 2005	Message Posted: Apr 7, 2009 4:15:06 PM Ignore rayw45 Report Abuse ??? All gas in Jersey is E10 during the winter, Shell included. The mpg level is about 10-15% lower with E10 no matter what brand.
