Valvoline Lubrication Recommendation Guide

EFV-8 Club Forum - CORRECT TRANS AND REAR LUBE. Topic: CORRECT TRANS AND REAR LUBE.

DEUCEMAN - @ 6:54 AM Please can anyone tell me the correct lube to use in a '39 trans with lincoln 25 tooth gears and in the rear, a '39 banjo with 4:11 gears. Some say 140 wt, GL4, others say the old Ford 600 wt and some say synthetic and others say no. In the trans if you use synoil the trans will leak and jump out of gear as the lube is too thin. Please may I have some suggestions. Everything is rebuilt, lass than 1000 miles and I'm currently using Ford 600 wt lube as that's what the rebuilder recommended, saying 'that's what Ford recommended', just change it frequently. Supereal - @ 7:51 AM Duece: Don't use 600W 'oil' in anything.

It is a thin asphaltic compound originally designed for use in the Model A's, which had transmissions that wouldn't hold conventional oil. It is obsolete, and will damage your gear boxes. We use 140W in our cars and trucks gearboxes. It tends not to leak if the level is kept below the filler hole. You should just be able to find the oil by crooking a finder into the filler. If you can't find 140, the usual 80-90 is fine.

These modern lubes contain additives for 'high pressure' use, ideal for most gearboxes. As for 'what Ford recommended', most, if not all, lubes in the manuals have long since become obsolete. Modern oils are light years ahead of those. The exception is synthetic oil, which while a fine lube, does get dirty as quickly in old engines, and requires as frequent changes as conventional oil. It also has the added disadvantage of being hard to contain with old style lip and rope seals. You can do a whole lot of oil changes for the price of synthetics, as well.
