Shell Nitrogen Gas

**karpetcm** · 03-06-2009, 08:01 AM

Well shell has come up with gasoline that has nitrogen in it to clean the engine better and provide better performance. My question is i usually will go to shell gas stations when i need to gas up but do you guys think putting nitrogen in there gas is more effective then chevron with techron or any other gas out there or is it all mostly just marketing. I dont know much and i know alot of people here are very knowledgable and trying to get some opinions seeing if its worth just using Shell from now on.

My bad didnt know it was posted earlier, either way it answered my questions its mostly marketing and chevron with techron would be just as good. How many gallons of gas do our cars hold exactly trying to figure out my MPG.

Depends on the year. its in the tech stickies.

Best way to do it is fill up, clear mileage, drive, fill up till it clicks again, divied miles by gallons. woot

Lucky SOB...I wish I was getting 15!

Well im still driving on the gas and havent finished yet but as we speak its about 15MPG, damn driving my other car which is a civic i get 28.5 City and 34.3 Highway, lol. On my 01 M3 i would avg 16.8 with a lean code so will see how much my average is when im done with it. LOL, with 440 RWHP i wouldnt care if i got 10 MPG. It must be fun to have all that power, so your a lucky SOB.

what mods do you have to only be getting 15 mpg?

**karpetcm** · 03-07-2009, 03:55 PM

Its in my Sig up top but ill have it show at the bottom in this message as well, believe it or not i hardly ever floor it. I think the city driving really kills the MPG.

Damn, I just put a cam in and just got done driving it around 350 miles this weekend and I got 20 mpg. This was with half highway and the other half ripping around and having fun, so you might wanna check that. I used to get 26mpg untuned with longtubes...

my cars exhuast lately backfires everytime i shift hard acceleration or not. Its not consistant but will do it half the time im driving, noticed it wasnt that bad before. Not sure what it means or why its doing that soo much now then before.
