1972 fj40 oil question

[swsanders]

Basic question. What weight oil do you guys use when changing the engine oil? Thanks.

Do a quick search on the 40 thread or ntsaints build thread. They were just discussing it last week.

To answer you question I use 15w40 diesel oil. Some use 20w50.

Same here. Rotella (or equivalent other brand) 15w40 Diesel oil for the 40 and the 80.
