That's what I was scared of. It was with fresh oil and 2 bottles. That's for all the help guys. Where is a good place to get a set of injectors at a reasonable price?

Personally I like xdp prices. They offer bostech and alliant. Ive used a bunch of alliants with no issues. I cant say good or bad about bostech but they are slightly cheaper. There are also supporting vendors of this forum that can sell you injectors. You can request a price quote from the home page.

will running 15w 40 in cold weather cause stiction in the 6.0?

I run 5-40 Rotella synthetic all year round. I started using it when we were going to upstate New York in very cold snowmobiling, and I needed to be able to run in very low temps. I was so happy I kept it. Hot shot secret is best if you have a dirty oil situation where someone before you neglected their maintenance. If it's really dirty oil use hot shot to clean it up and rev-x with synthetic to maintain. XDP has been good to me. Can you get a scanner showing you cylinder contribution before you replace injectors. Also is your fuel system up to par? Gel will cause problems too if it's cold there! 38 shouldn't be bad but if colder over night and you are coming in early am ? Return will send warm fuel back to tank. . . .

Ditto on that revx! Expensive, but worth it. Way better starts!
