Engine oil Shell or Motorex

Rotella T6 now comes in 10w-30 as well as a 5w-40 both are excellent choices.

I'll always use T6 because it's cheap, available, and damn good oil

The interesting part is that the T6 was used to tow a camper from Indiana to the Oregon coast where we are now. It’s interesting to see the viscosity, flashpoint and Moly are higher in the T6 even after towing through the mountains and more miles on the change.

I wouldn’t go with 0W20. Most people thicken the oil up in these when they start getting excessive oil burning. Lots of folks running Rotella 5W40. I ran it for years before I got tired of paying the premium price.

I run rotella t6 5w-40, and she loves it

10w30 Rotella will cut your oil consumption by 70-80%, ran it in my last Subaru until the clutch went at 234k and running it in my current Subaru

Change the oil with Rotella T6 oil.

I use Shell Helix Ultra 5w30 in my 330i car. It also has BMW Long Life certification. I'm very satisfied with it and would recommend it to you. It also offers good value for money compared to other higher-end brands. You don't get better performance for the money you pay.

It takes a “synthetic blend” of motorex 15W50 oil. And uhh yeah works good I guess, don’t have to change it too often, and as far as performance goes, it doesn’t really matter because I’m on restricted power anyways so yeah ????‍♂️

I run the diesel Rotella T6 5w-40. My catalytic converter decided to start throwing P0420 codes around 58k miles and I spoke to a shop that I am going to have tune my car and one of the techs said that they reformulated T6 a few years ago and it has more zinc in it than it used to and that might have had an effect on my cat and it's early demise.
