I use Rotella 5-w40. I've been using it for like 5 years in my 02 1.8t and haven't noticed any wear really at all. I drive pretty aggressive, redline 3+ times a day.
I have done really well with Shell Rotella T6 5w-40 as well. All are good oils that you can get away with changing every 5-6,000 miles.
This Rotella T run looked good.
I have been trying the Shell Rotella T6 out for the last 3 changes. seems to be working out quite well so far. Just checked my fluids yesterday after 2k miles and I only needed about a quarter of a quart. not too shabby.
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
