Engine oil Shell or MOTUL

Motul x-cess. It cut my consumption down from just under 2qt/5000mi to under 1qt/5000mi.

I took my car to the dealer to drain the factory fill oil at 1400 miles and have Motul 8100 X-cess 5W40 oil added, they also did "Updated software level, performed 24R9 Recall"

When I bought my '80 MB 300SD I did an oil chamge with 15w40 Rotella. The first day it dropped below 35* it struggled to start. Below 25* it needed a few hours of block heater time. I changed it out to 5w40 Rotella T synth and 6 years later I've still never plugged it in, even in -10*F.

After a vigorous break-in and draining the factory fill oil at 1409 miles, added Motul 8100 X-cess 5W40 and then drove on a 5000 mile vacation from Wisconsin to the Pacific Northwest and back.

So far, though, it appears that engine wear and presence of contaminants, as shown by UOAs, are significantly "better" with Rotella T in my car's engine than they were with any other oil I used, and especially Castrol Syntec 5W-40.

I was running Motul 8100 and got tired of having to pay alot of money and get it shipped, so I did alot of research and found that overall, the Rotella is one of the best oils for the price, so I switched to that. I notice no difference in power, and it costs alot less

My Blackstone Labs analysis reports always come back with great results for my Motul 8100 X-cess 5w40. I get an analysis of every single oil change. It's a great oil.

And I use a 15W40 diesel oil year round here in the Bay Area, currently Rotella-T, but have used Mobil Delvac 1300, Delo and others.

i always used 15w40. usually shell rotella in all my old diesels. sometimes i used castrol. but it was always 15w40

Rotella T 5/40 syn hopefully going in this weekend after a seafoam treatment. 25 CAD for 4 litres, inexpensive as it gets up here and you can get it at any TSC or truckstop.
