Brands of fuel
Greetings. I am new to the site. I purchased a 92 SSEI about 8 months ago. I learned much from this site about the various "quirks" the vehicle is known for. My question is 1) regarding the brands of fuel. I do use 91 octane. When I use Arco gasoline, the car runs rough, and sometimes kicks a bit. After getting that fuel out and using Chevron or Union, it'* okay. So, I know, don't use Arco. Has anyone else encountered this problem using Arco gasoline? 2) I am no mechanic, and follow the mfg'* advise in using 91 octane. Some so called "know it alls' tell me I am just wasting $$. That the car will run fine on quality 87 octane rated gasoline. I haven't, fearing that I could damaged the fuel injectors. I value your thoughts on the above, and thanks! Oh, it'* a California car with all the smog stuff on it.
