I have only run cheap oil in my turbo car for the last 30 years. Ran Smittys, Peak, Supertech and many off brands I can't remember. As long as it is API approved and is cheap I have no problems. Just read the label and check out PQIA to be sure. I like Chevron in my new car (11 years old), but I get that on sale for not much more $$ than the off brands.
