To the topic,I like blends but for long drain intervals I don't like near dead residual dino left over that does not drain out,,at moderate intervals for me at least of 5-6k blends,more than that I would prefer a pure synlube,,just how I would work it for my own use anyway
Originally posted by Patman: A fully synthetic oil is going to be able to go longer drain intervals and will have better cold weather properties than a blend would. Keep in mind most store bought blends are a huge ripoff as they are only 10% group 3 in their base oil, and don't really offer any benefits. Although in the case of Schaeffer blends it appears they perform just as well as many full syns do, but that is a unique case. I can't think of another blend out there that compares to Schaeffer's blends. Their blend is about 25% synthetic.
quote:I did not say your motor or anyone elses would self destruct just to clarify ,I said I prefer not to run a oil to it's limit or past and pour new oil on top of near dead residual dino,blend or not I believe it will tend to make the next interval a shorter one making the oil clean up whats left over and knocking the TBN down prematurely.What you or anyone else does is your own business,thats why I chose the words I used as in the way "I " prefer to do things I know what you are doing,and that is not a interval. Intervals are when you run to X miles and change oils and filter,you are changing filters and topping off with new oil last I read anyway but that was yesterday,this is a new dawn
