Has anyone noticed a difference on how the car feels depending on the gasoline they put I to the car? I normally put in shell premium, but I filled up with 76 this last time. I gotta say, the car feels better. I wasn't anticipating that at all, and I'm pretty sure it's not in my head. Thoughts?

 

I tried Shell the last fill up and noticed more difficult to start after hot. Normally use Sunoco.

 

As long as you're staying with a "top tier" brand (both Shell and 76 are) then I'm pretty sure it's in your head.

when i drove a chipped 335, i had problem with 76 gas. It seemed 76 gas contained higher percentage of ethanol which caused HPFP failure.

I only used 76 occasionally, but every time i did, my car sputtered.

Now, i do my best to use Chevron.

 

I use the 93 Chevron? Is that a good brand?

 

Chevron blends excellent gasoline. You're lucky you can get 93. Most out West is 91.

My choice for gas suppliers:

1 - Chevron
2 - Union 76
3 - Shell

 

Dealer in Toronto suggested shell 91 but I switched to petro Canada 94 and no issues.

 

kk thanks for the feedback

 

Does bp gulf mobil sunco all have diffrent blends? Is all there 93 the same? Intresting topic. Is it bad to mix the gastions i try to keep one brand

 

Likewise. I run Chevron in all my cars. Shell in a pinch. When I lived in the Northeast I ran Chevron or Sunoco 93. Here in LA it's 91.

Likewise I find that 76 seems to use more ethanol and causes my wife's Mini (turbo) to lag more. I don't notice it in the NA cars.

 

turbo cars seem to be more sensitive to gas brands.

i stick with 76, valero, mobil, shell or chevron. i avoid arco largely because they don't accept credit cards. i think sunoco and BP are just fine too. I avoid no brand and run down stations because they can have contaminated underground tanks. they also don't add detergent additives

 

Hate to be an "I've heard" poster but I think I've heard the Detroit car manufacturers have Chevron shipped in for their MPG and performance tests. Anybody confirm?

 

I switched from petro can 94 to Shell 91 because of the ethanol content. I have better mileage on the shell

 

Relevance?

 

He is speculating that Chevron gives better mileage and performance.
