Engine/Transmission (1998.5 - 2002) amsoil 15w40HDD vs 15w40 CJ4

[JCyrbok]

Need to order a case of oil for my truck (see below) and noticed that Amsoil has a full synthetic 15w40 CJ4 for 2007 and newer trucks. Would there be any advantage to running that in my 01? or should I just stick with the 15w40 Heavy Duty Diesel/marine (that I know works, got 40k miles on my current oil).



The CJ4 is 10. 4 TBN vs 12TBN for the HDD.



Just curious before I order.

I'll go first..... and i'll probably p--ss someone else off. :-{}



If you going to pay the price Amsoil wants get the Royal Purple synthetic, especially in a 2nd gen. It's probably the same price (or cheaper). It also has a CI4 Plus rating. I believe it's above the 12 on TBN properties your concerened with.
