Ran t4 10w30 in my 95 Cherokee for the whole time I had it and it loved in. Never ran better
Owner reviews for engine oil
Previous comments about mobil 1 are right it’s best for reliability - castrol are seen as high performance oils
mobil 1 is trash. i go with castrol5w40 or motul 5w40 or rotella diesel 5w40
I ran diesel oil in my '94 yukon for the entirety of it's 260k miles. My dad always said the same. The zinc was better for it. When I got rid of it, it was still running fine and driving fine.
I use valvoline 5w-30 full synthetic in my g35. Runs great
I use Motul 300v 5w40. I also drift so depending on what you’re doing it could be overkill. Before I just used Royal Purple 5w30 or Castrol full synthetic 5w30.
Can support the 1/4 cup of MMO in the engine oil. Had a Triton with a tick and adding the MMO made the damn thing run as smooth as a sewing machine
I’ve been using rottela t 15w-40 in my 70 Camaro for this reason.
For my Z with 210k miles i switched to the one your holding and it burns less. I get an extra 150 to 200 extra miles compared to mobile 1.
I have ran mobil 1 0w-40 for a long time without issue but am thinking of switching to thicker this change as it's starting to leak out one of the oil seals into compressor housing.
