Does anyone ever see a difference in fuel economy based on the brand of gasoline? (comparing the same octane) With all the ads about how clean or more efficient a brand is over another, I'm curious is anyone has actually seen a difference.

It is cheaper and for a reason. _____ My experience has been that the generic companies like RaceTrac, Pilot and Citgo will charge the prevailing rate for the location. I have seen a number of occasions where a RaceTrac station was charging the same as QuikTrip which sells a Top Tier fuel.

It has run just like new since I bought it, but started to miss a little and my milage was lower than it had been. When I asked my service guy, he said before wasting any major money, I should tell him about the gas I used. I did and he told me to make sure to use only premium and only Top Tier gas. I was told to run that for a month and if I still had a problem to come back in. After the second tank, the miss was gone and my milage improved by 2.5 MPG. ______ Generic gas like RaceTrac, Citgo, and Pilot have only the EPA specified additive package which is insufficient for today's cars. This problem will only get worse as we begin converting to direct injection fuel systems. The service technician's advice is only partially right. If the car only requires 87 octane, it's a waste to buy premium. Many of the premium fuels do have higher detergency levels and if the car has deposits, then the high detergency should help but it's only needed for a short time. Even regular octane Top Tier fuel has enough detergency to keep the engine running smoothly. As for the 2.5 MPG "gain", one should realize that what really happened was that the 2.5 MPG was mileage that was recovered once the deposits were removed.

However, taking note that you used the word gasoline rather than gas or gasohol; there is a difference there. Everything I have ever put gasoline in rather than gasohol has gotten noticeable better MPG.

Houckster Champion Author Atlanta Posts:9,338 Points:693,295 Joined:Sep 2003	Message Posted: Nov 20, 2012 4:38:33 PM Ignore Houckster Report Abuse No one should see anything more than a very, very small difference in mileage between gas brands. Mileage is determined, assuming an engine is in good condition, primarily by the energy content. Real gasoline (E0) should give better mileage than E10, for example. The gas companies don't even advertise better mileage these days. It's all about keeping deposits from building up in the engine.
GrumpyCat Champion Author Alabama Posts:2,594 Points:786,900 Joined:Jun 2009	Message Posted: Nov 20, 2012 12:56:44 PM Ignore GrumpyCat Report Abuse Yes, but its not really by brand. It depends on the local distributor. Locally Exxon was the worst gasoline available until Kangaroo changed their source and moved into last place. I don't have problems with Exxon when out of town.

OilerFan Champion Author Tulsa Posts:14,032 Points:2,445,440 Joined:Aug 2005	Message Posted: Nov 16, 2012 7:44:45 AM Ignore OilerFan Report Abuse I've never seen any indication of a measurable difference in mpg from one brand to another. And I also believe that if there was a measurable difference, AAA would be telling their members, as well as many of the car magazines and Consumer Reports; and it would be on the news for people to be aware of.

dontuknowOH Champion Author Ohio Posts:2,098 Points:36,565 Joined:Aug 2009	Message Posted: Nov 11, 2012 9:55:26 PM Ignore dontuknowOH Report Abuse I have noticed at times, just a few, that my idle speed drops 50-75 rpms after engine is fully warmed to normal temps.I simply think that is due to a higher % of ethenol in the refueling mix or the fuel pressure regulator is changing slightly with a different fuel-tank level,posibly atmospheric pressure is changing (weather related....? No problem really but noticable. No change in mileage detected,radio antenna will resonate and that is visible at times when the rpms drop slightly.Then again the extra coolant fan could be kicking on/off unnoticed with the radio/CD playing.
