Rotella T6 or Mobil 1 TDT.....

Johhny04 · Aug 3, 2011

Hey guys, i've been using Lubro Moly 505.01 5w-40 for the past 160k km with no issues, but I feel like its time to try something different. I've been doing a lot of research and reading regarding Mobil 1 and Rotella T6 and can't make up my mind on which one to change too. What do you guys suggest? Appreciate your opinions.

The LM 5W40 is very good.

I use the LM 5w40 as well.

If what you use works well and doesn't cost too much, don't change it. No need to introduce an unknown when when you have a well working solution.

Are you guys talking about the purple LM 5w-40 bottle? I use the 505.01 spec (blue bottle) which is a group III oil. I wanted to move on to a Group IV oil base.

I would go with T6 - price vs. quality is excellent

Been reading alot of posts from Drivbiwire and from his posts, I think the best one to go with is Mobile 1 TDT 5w-40. Come on what do others think?

If you go on the website bobistheoilguy.... most of the people recommend T6(the blue bottle)

I've been on there too but can't find anything specific stating that T6 is better then Mobile 1 TDT for the PD BEW engine.

I didn't think the TDT was a Group IV oil...

Any of the oils you've listed would be fine for your PD Jetta. I'd pick based on price as T6 & TDT both seem to do wonders for cam/lifter longevity where the 5w30 505.01 oils don't appear to have done so well. Then again there's nothing wrong with a 5w40 505.01 oil either.

But since you're in Canadia, why not give Petro-Canada Duron 5w40 a shot?

Can someone confirm. Is Mobile 1 TDT and Rotella T6 Group IV oils or no?

LNXGUY · Aug 5, 2011

T6 is a Group IV, from all the reading I've done TDT is definitely a Group III semi synthetic.

In this case, T6 is the easy choice.

T6 is Group III+ (Shell XVHI). TDT is *probably* a Group III/IV mix. No semi-synthetics here

Rotella T6 or Mobil 1 TDT.....
