Rotella Oil

[mtnman1989]

Does anyone use Rotella T-6 full synthetic 5W40 motor oil in their RV?

I have a 1994 Chevy 454 with 50K miles on it.

I use Rotella T-6 in everything I have and was getting ready to change oil in my RV. I been using Mobil One 10W30 but I have plenty of Rotella T-6 5W40.

40 weight sounds pretty viscous. What weight is recommended for the engine?

Use it! Its just an expensive oil to be using with something with factory oil changes.
