In my area Mobile 1 is about $0.10 cheaper than what Amsoil 7500 is. I recently compared 3 2.7l engines, 1 running Amsoil, 1 running Mobile 1, and the 3rd running conventional Castrol. All 3 trucks were within 5k miles on the odometer and the oils had been used from the 1st oil change. When you looked at the cam through the oil fill cap, what little you could see, the Amsoil truck looked brand new (no build up at all). The mobile 1 truck was very close, and the one running conventional had a considerable amount of build up for around 50k miles. This is all the proof that I need personally. We could debate this till the end of time, and there would be no winner. The fact is that there are thousands of Toyotas on the road with 300,000 - 400,000 miles, no major repairs, and that have ran conventional oils their entire life. I personally do not think that running Mobile 1, Amsoil, or any other synthetic oil is going to make a huge difference in the longevity of the vehicle. I fell that the most important thing is to make sure that the oil and filter are changed at regular and reasonable intervals to prevent breakdown, and to get the dirt out. I personally run Amsoil for my peace of mind, and I go no longer than 5k miles without changing the oil and filter. I do not think that it make a hill of beans what kind of oil or filter you use as long as it meets or exceeds the manufacturers reccomendations, and is changed when it is supposed to be. It's just my .02.
