nope. the sm oils have nothing in them to protect older engines. the sm oils are better in all ways except in protecting the cam. if you could boost the ZDDP you would have one hell of an oil. valvoline makes the best right now called valvoline synpower oil treatment. will boost ZDDP 120 ppm per ounce. it runs about 5.00 a bottle.

I was reading the back of a bottle of napa premium oil at the shops today and it said API SM but below said compatible with all previous API ratings and then listed a bunch of other classes. So in other words according to what is going on here, they are lying? What am I supposed to do when winter comes around and I need 5W-30 for my engine?

The VR-1 is listed on Valvoline's site as SAE 30, 40, 50, and 50, as well as 10w30 and 20w50. Finding a store that sells it may be the problem.
Big Lots has CD-2 Street Legal High Performance Oil Boost for $1.99 a bottle with 4500 ppm zddp. Half a bottle should do it and it is half to a third the thickness of the Synpower Oil Treatment.
Also Walmart sells Powerservice Diesel Lube Oil Extender or something like that which I believe was about mid 4000s ppm zddp also (VOA on Bobistheoilguy).

Anybody have any advice as far as finding a 5W-30 for winter time? I know in summer I can run a diesel oil like Rotella-T, but what about winter? Do they make a 5W-30? Also, are the diesel oils available in a synthetic blend? I like the idea of a little bit more protection for the extreme hot and cold, but since my inline six is up there in years I don't want to pour in full synthetic and watch all the pin holes spurt oil everywhere.

why not just use the rotella year round? they have 10w30, never seen a 5w30 rotella... they do make 5w40, but thats a synthetic. Rotella is a great oil!

Diesel rated 5w-20? Yepper, and here it is:

Did any body state that it had to be CI-4+? Yeah, I know, it's splittin' hairs but it is diesel rated. Other brands fall into the same catagory in that they are diesel rated, just not a current diesel rating.
