[Lung]

i have been reading articles and post on TDR for years about all the good oils. im not going to bad mouth the ones you guys think are great. however i have owned a large consruction company for years. the best oil to use is DA oil. they have oil made for your specfic need. they also have free oil sampling. check out there website and ask your Amsoil rep how is oil Compares with DA oil. we have used this oil for about 20 years. it has all been on extended drain intervals and we have had great luck with it. they have a new oil out just for all the new EPA engines.
