i wonder which brand other S2000 owners choose, 76, Chevron or Mobil.

 

Whichever is closest and cost less. I don't think there is any significant difference between each of the brands you mentioned.

 

Shell.

 

Shell here also, Amoco if Shell isn't available.

 

Chevron.. since from what I've read Techron is the best additive to gasoline..

 

Sunoco here.

 

 

Techron

 

Techron is the lable that Chevron puts on their bottled fuel additive. I think the true name is actually Techroline.

 

Here in CA, the forumula for premium unleaded (all we get is lousy 91 octane) is exactly the same. The only difference between Tosco (76), Chevron and Exxon/Mobil is the additives and color that they add to their product. Color makes no difference and additives are personal choice.

Go with whatever you prefer and/or is cheaper. Unless you have a dishonest station owner you're essentially getting the same thing.
