Engine oil Shell or RED LINE

Shell Engine oil

T6 Rotella 5w-40 when I run test pipes on tune, the heavy weight is great for keeping oil temps down and the zinc is awesome as a friction inhibitor but is terrible for cats so when I’m going to pass emissions I run Kirkland 5w-30 full synth on stock cats.

Pros: heavy weight, friction inhibitor
Cons: terrible for cats

I use 5w40 shell helix ultra on my 520i. It doesn't burn a single gram, it's relatively inexpensive (cheaper than the liquy moly I used to use) and is BMW long life 01 approved. The car runs smoothly, I'd recommend it

Pros: car runs smoothly
Cons: relatively inexpensive
Vehicle: BMW

Rotella T-Syn is a great oil but for our turbos...i wouldn't recommend it since if any oil gets burnt or makes it way through the rings...the higher amount of ZDDP (zinc) found in the Shell Rotella Synthetic oil will be harmful to your catalytic converter which may cause a failure.

Pros: great oil
Cons: harmful to catalytic converter
