Synthetic oil @330K?

[TexasR.N.]

Howdy All,
I am thinking about switching to a synthetic oil but have concerns with this many miles on the engine. In the past I have heard that synthetic will leak thru places that conventional oil wouldn't.
Any and all thoughts or comments are greatly appreciated.
Thanks,
Craig

ya it might eat your gaskets and and stuff for some reason but it will get rid of all of the sludge

The gasket materials that are used in our engines are not the same of much older engines. You can use Synthetics with full confidence that you won't develope leaks.

the main issues in older engines were cork and low quality rubber seals. Your powerstroke only has a, pan gasket, head gaskets, the entire rest of the engine is assembled with High quality oring seals and metal gaskets with orings.

If I can be of any help let me know

If you use syn to it potential yes it will save you 50.00 easy every 10k miles.

Synthetics arn't a new thing but new to many people. They have huge value even to older engines. Dinos do the job they are intended to do, synthetics do them better. With a higher number of Additives and highly refind POA group 4 base stocks good syn products flow much better in cold weather than dinos do.
