I'll let the numbers speak for themselves.

Old mpg: 18.6
New mpg: 20.2

Granted, I believe this was the first time any injection cleaner has been used in 60k miles, but hey, I'll take those numbers any day. I haven't noticed a performance increase, but I didn't expect to. After my 60 k tuneup, I think I'll finally be happy with my mpg.

I'm still stuck at 16-17 MPG, but that stuff did make my car go up to 18 MPG last summer

 

chevron 93 is all i have used for years, i am tempted by the shell vpower rated a 94 but not available really to most. when im over in Louisiana i have been putting some in the tank ! lol

 

I'm surprised to see you folks are getting this sort of fuel economy. I consistently get ~23-24 mixed driving and 28 or more on the highway...but I drive the car conservatively.

 

23-24mpg city AND hwy with Chevron 91-octane only.
