Halftrack oil

[wreckerman]

Hello group

What do other halftrack owners suggest using for an engine oil?

I tried a word search but I don't seem to have much luck with the G503 search engine.

Thanks

Dan

Shell Rotella T Triple Protection, 15W-40 Part# 550023277.

It has the zink in it, and its tech department bulletin recommends it for 1990 and older equipment with older style cam shafts.

A lot of guys use it in the G503 jeeps too. I have used it for about 10 years in my MVs. It is reasonably priced too, and available at most truck and auto parts suppliers locally.

I use the synthetic version in my 1967 John Deere 2020 for pushing snow in winter.

I use the same thing for all my vintage vehicles.

Hello group

Thank you for your input.

A research shows Shell Rotella available as Rotella T Triple, Rotella T1 and Rotella T3 .

Rotella T Triple and Rotella T3 sounds like the same thing but the container label coloring is different.

Which one do you like?

We need to keep track of this as the ZDDP levels are dropping (DPF filters and CAT's) in the Diesel oils (label change?). They "WILL NOT" tell you it has been lowered but one of the ratings may "disappear" or it may say "Meets the new" standard. In time, I think the "not street legal" motor oils will be the only ones available that has an adequate level of ZDDP to protect these old engines.
