Synthetic oil

Rule #5
Don't trust change intervals on the bottle of oil, use your owners manual.

Such as Mobil 1 annual protection.
 
I think I decided to use rotella in my next change for the Mule.
Here is what the owner manual states for viscosity in this engine.
5W30,10W40,10W50,20W40,20W50.
For my climate area what do y'all think I should use?
I've ran 10W40 all time. Or should I use 15W40.
:wink:
 
What's your climate type and how is the equipment housed in the winter?

If you're in Conroe, Texas I'd run 15w-40 all year long.
 
Yep, Texas. Mule is kept outside year round and used year round.
Hot as heck in the summer and mild to frigid winters.
Thanks cpurvis.
 
Let's see what Buddy has to say. He's done a lot more research on oil than me and he may have a different opinion.
 
new surroundings (here) have created a state of confusion for me. Today was a bad daty so best not try & reply.
