Ken_P Posted April 18, 2020 Share Posted April 18, 2020 My dad has a 1954 GMC half ton. He is looking renew the lubricant in the steering gear, and his owners manual refers him to "SG lubricant" - steering gear lubricant. Any GM experts out there have advice on what to use? I know on my Packard, it specified 160w oil, and apparently cotton picker spindle oil from tractor supply company is a near perfect match chemically. Not so sure on his pickup though. Thanks!

Ken, It is generally used for older vehicles to prevent leakage from older (teens & 20's) steering gears that have no elastomeric seals. But it should also work just fine for your GMC.
