synthetic oil?
I was wondering what you guys thought about using synthetic oil. Someone told me the 5w40 full synthetic diesel oil is great. What arw your thoughts? Do they make a heavier synthetic for diesels? The heaviest I can find is the 5w40. Will this be fine in my 7.3 or should I use conventional?

Follow up. I currently have a synthetic blend In and just got to 4000 miles. So I went and bought a new oil filter and changed it and topped it off with rotella 5w40 full synthetic. After this I noticed a considerable gain in power. Is this because of the thinner oil and the hpop can pump easier making the injectors more efficient?

I use Shaeffers 15/40 but it's a blend.

You are truly a testimonial and supporter of Shaeffers, you should get at least a gold starr for your support. I hope your trip is going well this year :) |
