I have a 1979 351w engine and have low oil pressure at temp(good oil pressure when cold) I am currently running 10-40 will going to 20-50 help?
Engine has 250k miles and has never been rebuilt
I have confirmed the oil pressure with a mechanical gauge
my local ziebart has a oil undercoating option they apply annually then they have the rubber one… I was thinking of having them do the oil one or is that a no go?
If I apply oil like fluid film over existing rust will it let the interior rust get worse?
