Hi all
I have a 73, 4 speed 340 Cuda,
what would be the best oil's to use for the engine, power steer, 4 speed box and diff?

Also what brake fluid? dot3 or dot4?

Thanks

I use 15/40 diesel engine oil, it contains zinc. if you like synthetic oil Z-rod by aims oil. I like regular power steering fluid back in the day they used type F automatic transmission fluid. Chrysler corp stated ATF could be used in the manual transmission. I all-was used 80-90 gear oil, same thing with the differential. again I prefer synthetic's my 2 cents worth but I hope this helps.

Brad Pen for engine oil, that's all I will put in my classics.
