I store my 84 Cutlass every winter from as long as November to May (depending on how soon the bad weather comes and how long before salt seems to be mostly off the roads in the spring). We put all new gaskets in the 76 350 Olds engine in 2007, so they are getting up there in age now.
I have been running m1 0w40 FS euro lately, but last winter I stored it with fresh m1 HM 5w30 and ran that for a couple months after storage.
I'm wondering do the seal conditioners in HM oil do anything when the oil is cold or do they need heat to become active? If that's the case there wouldn't be any point in using it for storage.
The rear main seal is a ford 292 fel pro as seen in this picture. It says it's rubber. I don't recall what all the other gaskets and seals are made of. It's been too long. I'm just hoping to protect the valve seals, rear main, oil pan gasket, etc.
Thanks for any input on this.
