Engine/Transmission (1998.5 - 2002) Amsoil 15W-40

Anybody tried the Castrol Tection diesel oil? My local Wal-Mart had it on clearance for 5 bucks a gallon.

Read John Martins article on oils in TDR issue 58. Actually Robert Patton did the

article with info from Martin. Amsoil Prem. Syn. CJ-4 was among the bottom

of the list. You can get Valvoline Premium Blue Classic CI-4+ for less than half the

price and he rated it at the top.

I am using synthetic 15W40 Royal Purple because it is available with the CI + additive formulation. I am of the understanding that the CI + formulation is superior to CJ, at least for pre 07. 5 models. Although I don't know how the cost compares to Amsoil 15W40.

8. 97 TBN (its a 12 TBN oil out of the bottle).



J-

Sounds like it is hanging in there just fine.

There is no other choice. I do have to admit, though, I use the Amsoil 10w-40 that is CI-4 because that is what I use in my tractor and all my lawn equipment (keeps down inventory). It does just as good.

I used to run Valvoline (cummins), good oil, but have been using amsoil for a couple of years now and oil samples are awesome, emissions are great, and instantley saw 3+ mpg better (city and highway). Now all my vehicles run amsoil products. I can't say enough!!!

I used amsoil 15-40 marine/diesel and my 01 used about a quart for every 6000 mi..... switched to amsoil premium 15-40 and the verdict is still out... by the way... rotella was used the previous 178k and it didnt use any... wtf? we will see how the amsoil premium does...
