Rotella Oil

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.

    Thats precisely why when I ran gassers I ran 10W-40 oil. When it gets HOT and starts to lose its lubricating ability a 40 weight still keeps you in the charts wheras a 30 wgt has let you fall off.

    Looks closly at your supposid charts and see what oil weights are recommended for what temp...and then looks when the temp gets HOT
  • 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.
