So is that article stating i shouldn't use 93 or 94 octane, only 91 since thats what our car states? I use 92-94 depends on where im at and how much i feel like paying. One time I filled up on 89 and used a bottle of f/I cleaner. Car ran awesome. Don't know why
My friend only runs race gas in his 69 camaro...
but it runs 9's and has 14 to 1 compression
