Oil Additive?

[SKIP780]

i see ya all agree that the synthetic oil is all that is needed.good job.come to think of it the trucking co i work for doesnt use any oil additive,just change the engine oil regularly (and an additional LUBERFINER filter). will stick with the synthetic oil only and 3000mi changes. thanks-frank

Back in the 60's we use to call STP.....Snake Oil....but I would just use good grade oil without any other stuff.....
