jmooner3 Posted January 18, 2012 Report Posted January 18, 2012 Guys - 1. What weight oil are you running in your trucks? I'm in Vermont but don't plan to run in winter. I thought I had seen a previous discussion but couldn't find in search. Manual says run SAE 30 over 32 degrees... Probably some better slick juice today then back in the day. Is anyone running 10 W 30 or 40? 2. I pulled the oil pan, cleaned out the sludge, painted etc, I noticed I have one oil pan bolt that is different (shorter) than the others? Is it stock and need to go in a specific hole or just someone lost one and used a different one? I've got a 1 in 20 chance of getting the right hole. Quote
Young Ed Posted January 18, 2012 Report Posted January 18, 2012 I run 10w40 in both my flatheads and Dad runs the same in all his too. Plus his v8s. Quote
MBF Posted January 19, 2012 Report Posted January 19, 2012 Ditto. A good quality 10-40 in the 52 Dodge, and 36 Plymouth. Quote
41/53dodges Posted January 19, 2012 Report Posted January 19, 2012 I run 20-50 in mine, but mine is unrebuilt, so this makes up for loose bearings! either way, it works well once it warms up, keeps nice pressure across the board. Quote
jmooner3 Posted January 19, 2012 Author Report Posted January 19, 2012 What oil pressure should I be registering? Quote
ggdad1951 Posted January 19, 2012 Report Posted January 19, 2012 What oil pressure should I be registering? If I remember right, I was about 50 psi Quote
Rusty O'Toole Posted January 20, 2012 Report Posted January 20, 2012 According to my 1954 Motor repair manual on a flathead Dodge car 1940 -54 you should have 45 pounds oil pressure @ 30 MPH except 1949 and 50 models 40 pounds @ 30 MPH??? Quote
