Adding Sea Foam to oil – 6.7L Dodge diesel [SOLVED]

Thanks for the question, Jeff. It’s never too late to start using Sea Foam your Dodge’s motor oil, so no concerns. Just add the recommended amount each interval and look forward to a cleaner oil crankcase!

Does Sea Foam keep your diesel fuel from freezing?

Hi Cliff. Sea Foam will lower the diesel pour point a little, but nothing like a specialized anti-gel product. Note that untreated diesel fuel starts to gel at 17 F. Depending on the temp you’re dealing with, you’ll need something that keeps diesel flowing. Hope this helps!
