Rotella 5W-40 synthetic ????

[2whlfreak]

Anyone using this oil, the owners manual states a 10w or 15w-40 . But I read somewhere that Ford has said the Motocraft 5W-40 synthetic is acceptable in all Powerstroke engines. Locally for me the Rotella is $10 cheeper by the gallon.

I havent tried it. I just run 15w40 because I get it for free!

I was getting the 15-40 free. Whats the Lucas stabilizer for?

It has special properties that helps the oil stick to parts for better lubrication and less of a dry start.

ISnt that why you use syn to start with?

The syn lasts longer does not break down under pressure or heat and helps control soot and carbon control
