Engine oil Shell or AMSOIL

rotella t6 5w40 diesel oil. nothing else.

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.

It's a little more pricey but extends change intervals and has worked for me. Keeps engine temps a bit cooler as well.

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.

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.

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

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.
