I know I have a topic already about the best oil to use, but as it gets closer to my time to change my oil I am going to use the K&N performance oil filter sense they seem to do a good job of keeping the oil clean and they are durable, and as far as oil why do most people recommend synthetic oil? I don't understand I thought synthetic oil was fake? That is what my uncle says but then again he hates Pontiac and yet he drives a GMC envoy :banghead: which frustrates me, but moving on why synthetic? And I have been told to use certain oil I just want something for performance and protection. Thanks for the help and comments.
