since my brother is an amsoil dealer i know this stuff, all amsoil simply does is has you send in a sample of your oil to blackstone and they determine if the oils bad and caused the problem. we run amsoil in the 11 cars we own and they get an oil change once a year, my father also owns a machinery moving bussiness with 10 semis and about 25 forklifts, they all have amsoil and recieve oil changes once a year, none of these engines have ever had a problem, have you ever tried amsoil? have you ever did any research on they're products? the guy who started mobile one used to work for amsoil, amsoils used in all the military planes because its the only oil that doesnt deteriorate, try it for a year and then if you decide you dont like tell me its *****, but until you try it you have no clue weather or not its the same as every other synthetic out there
Synthetic oils last forever.
Untrue. Although some "experts" feel that synthetic base stocks themselves can be used forever, it is well known that eventually the additives will falter and cause the oil to require changing. Moisture, fuel dillution, and the by-products of combustion (acids and soot) tend to use up additives in an oil, allowing degradation to occur. -Ed Newman, marketing manager for Amsoil, Inc.
Amsoil engine oil is better than non-synthetics and durablends, but so are the other synthetics that are API certified! I suspect that the major difference in performance between Amsoil and other synthetics is simply the amount of additives Amsoil puts in their product, especially after considering Amsoil's engine oil comparison tests and the Amsoil dealer retail prices. I suggest Amsoil eliminate the middle men and put their products on the auto store shelves, then see if their formulae stay the same and their product tests continue to be better than other major oil brand synthetics. As it is now, there really isn't a significant difference between Amsoil and other synthetic brands ... all exceed or just meet certification limits. The industry is price sensitive, so many major brands skimp on additives to meet guidelines and keep product cost down, and for other reasons, such as environmental guidelines. There are some "synthetics" that are made from petroleum, however, it from the high end of the distillation (gases). Most are just synthetic hydrocarbons designed by organic chemists. BigJim continues to disseminate reckless assumptions that synthetic oils are somehow the same as non-synthetic petroleum-based engine oils.
Exceeding the vehicle manufacturer's engine oil drain frequency is just outrageously imprudent and reckless. Larger vehicles have larger volumes of oil and will suspend larger amounts of engine contaminants to allow safe engine operation for loner periods of time over modern automobile engines. Jeep engines probably shouldn't even use synthetic engine oils except under extreme use in cold regions. Even sythetic oils breakdown due to factors such as heat and shearing; and, its additives are consumed by engine oil contaminants.
Playinthemud, you're probably a great guy, but you have to get over the product hype. almost every engine oil manufacturer has a synthetic oil that is made from the same basic organic compounds and additives that Amsoil is made. People are prone to adopt and promote what they buy, not necessarily based on Science and Economics. -F. Blackstone <img src="/forums/images/graemlins/cheers.gif" alt="" />
