Hi,
I am interested in using this in my truck (98 chevy ZR2 4.3L v6), which tends to sit for about a week at a time in between long drives. I want to use it for the moly addition as well as the antimony, to combat any possible rust or moisture issues. I do always gett he oil up to full temperature (I assume it is because I drive the truck over 15-20 miles continuous whenever it is used).
The first problem is that I worry about mixing it into my oils. Schaeffer's 5w-30s dont appear to have the newest specs(they all seem to be GF-2), and I want an SL rated, GF-3 oil. I currently have a good supply of Castrol GTX, which suits the bill, but I have to wonder if the mixing of two schaeffers products would be better than a castrol and schaeffers.
I usually dont go 3000 miles in 3 months, but because it is sitting a lot, I usually change it that way for peace of mind. I wouldnt mind extending the drain, because the oil is most likely fine after 3 months.
My ideas are as follows:
-use castrol GTX 5w-30, with the 132 additive
-use half GTX 5w-30, half castrol german synthetic 0w-30 and 132 additive
-use M1 0w-40, no other additives
-use delvac 1 5w-40 no other additives
What would be best? I worry about mixing too many things, even by the same mqanufacturer and getting an additiver clash and low TBN number. I also worry about using a 40wt oil, as they seem to rob me of a bit of power. I do like the extended drain specs of the m1 0w-40, but then again, it is a 40 wt, and Im not sure how good it will be extending the drain time with lots of sitting in between anyhow.
The key is to keep my engine as clean and new as possible for a long time, as I intend to keep this truck for a long time.
Thanks for your help,
JMH
