Valvoline Premium Blue...Cleaning effect??

[sevobuck]

Stopped by the local Cummins dealer yesterday to pick up some Valvoline Premium Blue. The service guy there asked what kind of oil I have ran in the past and I told him I just recently acquired the truck (70K). He said that if it has had anything but VPB in it then I can plan on burning off some oil and the the VPB would have a cleaning effect on my engine. Any truth to this?

All quality oils have excellent cleaning agents... . I had the chance to study oil quality many years ago while I was in college...



Its my personal thoughts that any good oil is no better or worse than another... . if you read the fine print you'll find the same stuff in each bottle... .



I had a chance to do some work for a bottling company in Portland OR... they bottled oil... in the 1 qt and 1 gal containers... and packaged it into cases... . off the same product line were like 5 or 6 of the major oils... . the guy running the operation mentioned that yea... in a 500 gal mix... there might be a 1/2 oz difference in one chemical additive over another... .



The real question you have... IS, did the first owner of your truck take care of it... . if so... your in good standing... if not... I would do the lube oil and filter change and come back in say 2500 miles and do it again... . just to be on the safe side... .



BTW - all my trucks go to a lube center. . fast, quick, and reasonable... at 7500 to 9000 miles... . on 2 of my trucks that every 3 to 4 weeks... .



I know this is going to flame some of the guys who love their brand of oil... Just my 2 cents worth...

The top tier synthetics like Amsoil and Mobil seem to have considerably higher "cleaning power" than your typical Delo 400 or Rotella. The difference is apparent when you pull the valve covers on higher mile Cummins. My '96 had been run on Delo 400 all its life and had a fair accumulation of brownish residue. The ones run on Amsoil are pretty sqeaky clean.



I don't know about the "next step down" synthetics like Premium Blue Extreme, Rotella Syn, etc. I ran Rotella in my '96 starting at 355k and it did clean up some of the brownish buildup over the last 40,000 miles but it's not as pretty under there as the engines I've seen that have mostly run Amsoil.



At 70k miles I wouldnt worry about it, my only suggestion is to change the filter after about 1000-1500 miles and the oil at 3000 if you're worried about it, then stretch it to 7500 - 10,000 after that.
