+1 here....
Yep....which is why I typically always add a dose of MMO to my fuel...or whatever other additive I can find cheap
[censored], last month it was "AUTOGUARD Gas Treatment" from the dollartree.com
Can't beat that for a buck! And I did notice a longer tank run....but not necessarily a MPG increase.....whatever that means...lol. Basically, got a real good "trip meter" reading from a tank, plugged it into fuelly, and my MPG was down....hehe.
But I don't know...the couple times I tried Shell, it seemed the MPG "bottoms out" with the top tier.....basically, once it does it's cleaning, you no longer see a MPG increase
Soooo...now I basically only use top tier (depending on price...) maybe once a month or so....typically Mobil, or Shell as those are the 2 big ones in my area...
