The other day getting on to H1 I noticed my car was pinging (Tesoro 87). I'm testing the Shell 89 seems like the old 87 hmm.... is our gas getting shitty or.....

 

Sorry for the double post, didn't do anything after I clicked it once.

 

I use Top Tier Gasolines, 87 octane Top Tier Gasoline

 

try another tank to see if it was a bad batch.. i use sams club 87

 

Premium, where ever I happen to get gas.

 

Either 87 or 93 octane (if around $2.50 or less) at a Chevron, Texaco, or Bucky's.

 

i heard from the salesman at the dealership that tesoro gas sucks. you should only use top tier gas on hondas.

 

chevron regular.

you can always get a tank from a bad batch. ethanol is a bitch.

 

Yes I just got the worst MPG since my Fit was new 29.1mpg and the tank before that was 36mpg same drive to and from work....? gas companys changing from warm weather mix to cold?? Va.
Exxon 87 with 8 oz. of daddy's recipe with every tank

 

And what exactly is daddys recipe,lol?

 

well funny you should ask sonny ya take 1 part STP inject. cleaner and 1 part.......hmmm wouldn't be a secret now wood it?

 

Thanks, for the replies.. Shell and Chevron are Top Tier I don't know who Sam's and Costco get their gas from but, car ran good. I always liked Shell a posed to Chevron. I guess I'll run Shell and when I'm in the hood I'll go Sam's..

 

Stick to tier 1 fuels, and I avoid ethanol.

 

costco is aloha.

 

I do a bit of driving for my employer, so he buys be one tank a month. That tank is always Shell Premium, no matter what it cost. When I'm paying, I get the regular Shell 87. I ususally end up going trhough about 2.5 tanks per month and I always wait until I'm running on fumes before filling up "his" tank.

 

Aloha gas is top tier. Costco is top tier and fine.

87 octane is recommended for the Fit.

It doesn't make a difference to use Premium and just a waste of money.
If someone else is paying for the gas then you can waste their money.

You can check to see if you are pinging.

If your car manual says you need to use premium fuel then you should always use Premium even if it runs OK on 87 octane which it could but not as good as with Premium. It doesn't work the other way around.

 

Okay, I did some testing Shell and Sam's Club gas work a little better than Tesoro but, still get some detonation around 3.5k getting on to the freeway 4th gear. The only thing I can think of that's causing it is the lighter crank pulley. I ran 89 Chevron tonight and my car's a lot quieter and and no pinging.
