I just bought an 04 F350 with a 6.0 Powerstroke. It has about 193,000 miles on it. This is my first diesel, so I don't know a lot about it. It is running a little rough when it is cold, from everything I read this sounds like an injector stiction issue. I've got some diesel kleen in the tank and I'm going to try some Archoil AR9100.
Anyway, I have a bunch of Royal Purple 10w30 and 10w40 oil. 15 quarts to be exact, just what the Powerstroke needs. It is about 4 years old, just before they took the zinc out. (can't remember the spec) I want to use this oil up, I'm wondering if it would be any good in my engine? It's not diesel rated. Are there a lot of people running 10w30 in these motors? I understand it shears 40w down very quickly. I have half and half 10w30 and 10w40, can I mix them?
I am in Oregon and it doesn't get that cold here. I'll probably use a 5w in the future, but this is $130 worth of oil I'm not using...
