Fluids

[old rat 49]

What are the engine, trans and differential fluids every one is using now ? Topped everything off when I got the car last year and oil and filter change in engine. Put about a hundred miles on it this week since I got it legal to drive and doing ten to twenty miles a day now. Plan on renewing all fluids first really nice day next week and would like some suggestions. Oil pressure is running a little low at this time and will rebuild/replace pump soon.

had good service from Tractor Supply Traveler Diesel oil. 10 40 but running in a recently rebuilt engine. Watch what you put in the transmission. Lots of the new gear lubes are not brass/bronze friendly (not good for syncros) Look for SG4 or lower.

Why a diesel oil ? An example of what trans/gear oil ?

Is this the same as GL-4?

My very old greasy and well used service manual says to use SAE 80 FGL in the trans. Have spent 2 hours on line trying to find an equivelent modern grade and gotten nowhere.

Have you tried a forum search?

I've been happy with Rotella-T 10w40 in my '50 Wayfarer. It had sat for 16 years when I got it, had huge amounts of crud evident in the valve lifter chambers, and a great deal of smoke once I got it started. After a couple thousand miles of running and a couple of oil changes, the smoking is completely gone and it seems very healthy. I gather the reason for going with diesel oils is to get the zinc for the flat lifters--not to say but there is a good deal of "discussion" about whether this is necessary. All I know is it's running well.

Yes GL 4 was a typo.

Pennzoil makes an oil for syncromesh trans that is brass friendly
