Oil Recommendatiom

[Targojoe]

I have a F-36. What weight oil should I be using in my Chrysler 440's? port motor shows 60lbs at the gauge...starboard is at 80lbs at the gauge...

Chrysler says 30W or 20w-40 above 30 degrees . However I recommenced Using a good 15w-40 oil that's rated for gas/diesel like Rotella . Many newer marine engine recommend it . But any of the above will be fine .

Oil pressure spec is 45-65 psi @ 2000 rpm . I suspect the gage maybe off on the one reading 80 psi .

thanks...for the help...yes I'm going to put a mechanical preasure gauge on inplace of the pressure sensor to get an accurate reading.
