This might be a heated topic. What brand of fuel you use to get best fuel mpg? I have seen so many videos on brands that arw top tier. Lets see what the forum says.

I've normally filled up with premium at 76. After commuting sightly further for work I've switched to Costco and noticed slightly better MPG(27-30MPG). Both are top tier brands as well, which is a minimum requirement IMO.

I mostly use premium 91 octane from costco with my civic. Occasionally if Im driving home from class or work later at night when Costco is closed and am running low, then I fill up with premium 91 octane from Chevron but that's just in emergency situations where I need to fill up to get home. Costco is my main go to.

QT is my backup. Also gives me an opportunity to grab the 2-for-$4 monsters, haha.

Monsters, taquitos, burritos, breakfast biscuits, they have it all.

Comparing gasoline is like splitting hairs. Just drive slower and you'll get better gas mileage. Or make up the difference by ordering one less pizza during the year. Of all the ways to save money, gasoline is not at the top of my list.

In the '70s, here in so cal, when you could only get gas every other day.
You would pay any price just to get some. I remember thinking what a rip it was having to pay 67 cents a gallon for premium grade fuel.

Fortunately businesses were exempt, and I knew a guy...:winky:

Any top tier. As Mr. Egg said, your right foot has more to do with mileage than anything and, obviously, few drivers know or use their foot well.

My commutes are mostly city, as I live about 15 mins from work. The best way I can max mileage on these drives is 3k shifts. But, that's not why I bought this car, lol. And I'm already getting way better mileage than my Silverado, so I'm happy.

I actually get better mileage with the GTI than I did with any of my Si's. The GTI averages about 31-32 mpg whereas my Si's averaged 26-28 mpg. Same driving.

You say that now... But eventually carbon buildup will reaffirm what everybody knows; Vtec always wins.

To reaffirm what everyone is saying, it really doesn't seem to matter. I alternate between Mobil and Shell pretty often and can never tell any difference between the two. A 5 degree temperature swing will make a much bigger difference than the brand of gasoline.

That's why I leased it. I'm pretty sure I'll never own a car again.

Don't know if VW is one of them but most manufacturers using GDI are now also using a small amount of port injection to get the back of the valves sprayed and cleaned off.
