what brand of oil
On the stang, when I got off the Motorcraft Blend oil and put Mobil 1 5W-20 Extended Performance in, I left it in for 3000 miles to try and clean the engine of any possible buildup from the blended oil. Then I put in the M1 5W-30 Extended Performance And just hit 5000 miles. I will change it next week. Have felt little or no performance drop due to leaving it in for 5000.
Car Talk (with Click and Clack, the Tappet brothers) on NPR this morning talked about this very topic! Actually, the question was, if Mobil 1 is not available, would there be any problems or noticeable difference if using another oil?
Click and Clack's answer was as long as the substitute oil is another full synthetic, then it would not harm the engine at all, and it would afford the same protection. They said using Castrol Syntec would be a good example - it will provide as much protection and performance benefit as using Mobil 1.
They used the analogy of ordering a Coke in a restaurant, and getting a Pepsi instead - even though they are not the same, they both do essentially the same thing, and the Pepsi will rot your teeth just as fast as the Coke.
