Title: Castrol GTX diesel oil w/zddp
Post by shorty on 05/25/14 at 20:12:23

found this on sale, diesel 15w-40 Gallon jug and the label states zddp additive for extra wear protection..

I bought 2 gallons since my diesel tractor would love this, but I wonder if there is enough zddp for the LS650

Tractor Supply Stores is closing them out for $10.88 gallon, my Harley buddy pays almost that much per quart :o

I did some digging and found this;
CJ-4 rated diesel oil (Rotella & Castrol) have a LIMIT of 1200ppm zinc/phosphorus..
so does that mean there must be LESS than 1200ppm?
so how much of the s**t is in there? >:(

Well... if Rotella is "approved" with that wording, so I'd imagine Castrol probably has the same amount as Rotella. Hm.

that's why I'm using it in the tractor until I learn how much zddp is in the Castrol.
It has the exact same ratings as Rotella, CJ-4 specifically addresses zinc/phosphorus content. Castrol specifically states zddp in there for extra wear protection.

I believe it's the same, maybe the MSDS will state exact quantity?
Regardless I'm getting more ;)
