My supplier says 10,000 isn't out of the question though. And he's the one selling the oil so it wouldn't make much sense for him to be less than truthful only to not sell as much product. We shall see. Should be a cool ( albeit a long) experiment. |
Lube Watch oil analysis for preventative maintenance- Chevron
Great way to find problems early like injector leaks, coolant, soot, silica, viscosity, etc. Hijack over. |
Dammit, I thought it was like a pregnancy test I could get at a local autopart store. Let my truck pee on the stick, and tell me if I should be worried...

This is all good information.
Thank-you all. Keep it coming. Almost all good information anyway... Haha DD |
i have used royal purple 15-40 in my duramax for the last 175k mi.(281k total). I had the motor apart for 10 weeks and the oil still had everything coated. i kept wondering why my parts all looked dirty when another duramax i had tore down looked real clean and had been running rotella. I then realized that my royal purple had a coat on everything when the rotella had just run off. Thus, the royal purple prevents dry starts and i don't have to run an additive. As a side note the oil pressure has also increased approx. 10 psi.

I too run Royal Purple in bith my IDI and my Cummins trucks ..... I was genuinely amazed when I pulled the heads and hg off the ford .... SPOTLESS...... my oil pressure has also gotten better in both as well .
the ford has been running RP for 5 + years .... the dodge only about 3 months .... picked up milage on both :tu: |
2009 CUMMINS 6.7 RAM3500 4X4 DW
I use Mobil1 5 W 40 Fully Syn Turbo Diesel truck oil and Fleet Guard filters...I change it every 5000 miles...I had the waste oil tested along with a sample of the new oil the lab results were the same except for the suspended solids from the fuel and the soot...The oil is quite expensive but have you priced a new Cummins 6.7 lately...I'll continue spending the $100 on the 3 gallons of oil just for the piece of mind...
