I use it in my engine and going to be changing all my other fluids over to it soon. ok heres something for you to think about. Amsoil's trademark is "First in Synthetics" To get this patented they had to do 2 things. First prove that they were first as in the first to market synthetics to the public, which they were so no problem there. Second they had to prove that their synthetic was better than anyone else's as in being first. They submitted their test data and had to give all manufacturers of synthetics atlest 60 or maybe it was 90 days to contest the fact that they were the best. Well no other oil company contested that fact. Id say if the oil companies wont step up to the plate and contest that another companies product is better than theirs then I know whos product Im using. Not to mention can you find another company that will warranty anything that breaks that is oil related? I dont see anyone else doing this, Amsoil puts it in writing. Their engine oil alone they say to change every 25,000 miles or once a year and replace the filter every 6 months. Do I run it this long? Yes I do and have no problems doing so.[addsig]
