Hello, I have just acquired a 1979 F-150 4x4 with a 351M, I found documents in the glovebox that the motor was rebuilt in 1990 at 90,000 miles. The truck now reads 32,000 miles so I don't know how many miles on the rebuild. I bought the truck from a local who bought it at a dealer auction about 5 years ago, he has not driven it much at all in the past 5 years, he used 10w40 but didn't drive it in winter. I have searched the posts here but still am not sure what I should do as my situation is a bit unique. I will only be driving the truck about 3000 miles a year, mostly hauling firewood and going to the hunting shack. Most of these miles will be on dirt roads, and our weather here runs from 90+ in the summer down to -50 in the winter, I won't be driving the truck if it's that cold though
My questions are:
What weight(s) oil should I be running in the truck? I assume I should change the oil in the fall and spring to get the best weight for the seasons. I know that I won't have many miles on each oil change but that's fine with me, I don't mind doing it.
Should I be using dino, blend or synthetic? The truck leaks a bit of oil, will need to add some often.
What brands do you guys recommend, does anyone else with a similiar climate have anything that works good for them?
I am also going to change the differentials and NP205 transfer case fluids (tcase is leaking a bit), any suggestions there?
This is a great truck in very good shape, I want to keep it running as good as possible. I also am not very concerned with oil costs as I will not be changing it often, just want to use whats best.
This is my first post, I also posted this question on the FTE (Ford truck) forum, I figured the more opinions the better though!
Thanks in advance!
