Owner reviews for engine oil

Mobil 1 0W-40 is what I use; had 0 oil consumption problems w/ stock pcv.

Now i am referring to amsoil, Delo 400, mobil one turbo deisel truck oil.

in my Diesels i use amsoil or chevrons delco synthetic for heavy duty diesel engines.

Of course this is assuming you're using really good oil, something like Mobil1 ESP 5W-30 or at least the Castrol LL03 VW507.

i change at the extended interval and use only 100% synthetic oil usually Amsoil. I plan on using the same in my TDI at the normal service interval unless vw makes a full syn diesel oil

i changed mine @62k miles with similar results. i to change my oil around 5k and was useing m1 0w-40, but just recently started useing fuchs titan oils.

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.

The zinc and phosphorus levels (ZDDP) is much higher in the redline. Iron per 1000 miles is much better. Viscosity retention and flashpoint are much better also.

I love red line, search for my UOAs... i've tried most of the top teir vw502 approved oils in the FSI (Motul xcess, motul specific, total energy), and they don't even come close to touching red line with regards to longevity / performance.
