Reviews of Shell parts For Business

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.

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

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.

Personally I would run a higher detergent 40 weight oil such as Rotella synthetic 5W40 than a "high mileage" oil.

Rotella 5w40 here. IMO, I wouldn't run less than a 40w on the upper end if you do a lot of freeway driving.

I just changed my oil to Rotella T 5w40 Synthetic. It's great stuff. So far so good and the car runs smooth.

i use the shell anti freeze it says it safe on aluminum blocks .. so it has a lower corrosion factor.. (aluminum corrodes easly)..
