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.

One poster Yes if it is branded like phillips 66 or BP or Shell any of the big branded companies gas seemes to be better than the unbranded gas like a Casey's gas. or people that have there own unbranded gas. 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.

One poster writes: I drive a 2002 Acura and have always serviced my car with the dealership. 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.

Yes buy some Ethanol gas at 10% min. then get some Non Ethanol gas at 92 Octane and tell me which one you get better MPG on.

That depends more on the vehicle than the brand of gasoline. 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.

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.

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.

I have purchased Shell's premium clean diesel a few times, and also bought diesel from the Mohawk Reserve close to where I live. About 15 cents a litre cheaper on the reserve and no difference in MPG at all.

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.

Thanks for the input. I had never seen a difference by brand but find it interesting that many ads imply better mileage.

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.

I find it hard to keep track.
A) since i don't wait till empty to refill so my tank is usually mixed.
B) my driving habits change fro day to day so i can't compare.

I haven't noticed a difference over years. The only place I can see where it might make be a difference is buildup in the fuel system over time. I use a non alcohol additive about once a month.

I keep track of every tankfull since I first started driving and record every gas station besides the price. I never noticed a difference in gas mileage from one brand to another. Some tankfulls may get beter or worse mileage due to driving conditions, weather, and many other factors. No brand of gas has consistantly proven to give me better gas mileage.

I have tracked my mileage for years and at least in my vehicles the difference is not noticeable. I have even tried ethanol free gas as well and not seen much difference.
