Maintenance Schedule.

[Turbo Terry]

I’m trying to work up a maintenance schedule .The book says for warranty etc but I want to talk about differential oil. ( notice I didn’t call it gear grease). At 3500 I had Amsoil 75/140 severe diff oil put in front and rear . I haul heavy truck camper 3000 lbs 3-4 months a year. The rest of the year it’s empty . Book says severe duty 22500 miles and 18 months . Regular duty 45000 miles 36 moths . I would like to do the later. What do you think?

45 is perfectly for your use.
You aren't hot-shotting 20k trailers in Texas.

If more assurance is better, I 2nd 45 is fine.
