I just changed my oil with 5w30 Mobil 1 and a STP oil filter. Whoever said that Mobil 1 synthetic oil improves performance noticably, is smoking serious amounts of crack cocaine. the only difference you may notice is the fact that your car needed an oil change and wasnt running all that great, then you put in fresh oil.
Also, anyone who lists Mobil 1 as a "mod" maybe in worse shape in the drug arena than the people that claim it improves performance.
Just my 2 cents.
