I'm doing my best to research if I should or should not start using synthetic motor oil. I have a 2002 Toyota Tacoma 3.4L V6 with the TRD package. I’m just about to hit 40k miles on it and want to insure that my truck lasts as long as possible. The majority of my driving is freeways about 32 miles a day. I don't do any hauling or offroading, just your average commute type driving. I have done some reading about Mobil 1, Castol Syntec, and Amsoil. My first impressions are that there isn't anyway that amsoil can be that good. I have looked for conflicting information, but it seems the only info out there is on sites owned by their own distributors. As for the other 2 oils, they are made by companies I do have some knowledge of. I have spent the better part of 2 hours looking though this message board and I'm worse off than before. I’m no chemist, so most of the acronyms and numbers mean zip to me. I would appreciate any advice given. Thanks in advance.
