Which one of you would highly recommend me to use the gas octance for VE engine , Would it be more than 91+ octane ? My Engine is kinda of little bit shaking cuz I've been using regular ( 87 octance ) gas . So I think it could be one of those reason ? Which is the best gas station would u go to , Mobil or Sunco eh ? I think , I'll choose Sunco (SP)? over mobil cuz they have high ultra pure RICH gas. Every friday , I always put NOS octance fuel injector cleaner. Whatcha guys think eh ?

 

for my car , when i have money, i put in 92 octane from chevron. cause i've read that chevron has the best quality gas , could be wrong just what i've read.

 

i used to use regular but now i use 91+ everytime i get gas, the car doesnt shake that bad anymore... i go to whichever station is cheapest... i dont like the NOS brand stuff... try the Outlaw cleaner, oh and you dont need to use it that often
