I'm BLUE Posted February 15, 2010 Report Share Posted February 15, 2010 I just want to know the right specs of the diff oil needed for '77 MAZDA truck :rolleyes: What model , engine size , transmission please ? Thank you ! DTP Quote Link to comment
Mini-L320 Posted February 15, 2010 Report Share Posted February 15, 2010 Im pretty sure that it uses the same as the Rx7. You do have the stock Rotary in it I'm assuming. but seeing since this is a truck it could use a bit more oil, rear end is slight bigger, I could be wrong. Best bet is to find a cheap Manual for it on ebay, I just bought one for my datsun 210 and only cost me $10 shipped. Quote Link to comment

Farmer Joe Posted February 22, 2010 Report Share Posted February 22, 2010 the lube for the rearend is prolly gonna be 80w90 gear oil. thats what my 77 luv took and im pretty sure that m 77 datsun book says 80w90 for a datsun. id just run a good brand of 80w90 gear oil and youll be good to go.

Anything to make it clear ???? :cool: There is no brass or copper in the differential so use GL-5 80 W 90 or a good synthetic for rear ends. GL-4 contains less sulphur and is more tranny friendly. Nissan recommends GL-4 for trannys and GL-5 for rear ends. I think many new trannys are different and can use the GL-5 and the newer younger mechanics don't remember the need to protect the brass in the older transmissions. I've heard them tell people that GL-5 is better, and it is but also it's not compatible with brass. It's a slow process (corrosion) your tranny won't disintergrate if you use it. But it will attack the brass/copper over time. 1 Quote Link to comment
datsunaholic Posted February 23, 2010 Report Share Posted February 23, 2010 Basically if you have brass or bronze parts you need a yellow-metal safe gear oil, I don't know about Mazda diffs but as far as I can tell there aren't any yellow-metal parts in a Datsun rear end. Transmission, there are. And not all GL-4s are yellow metal safe, and some GL-5s are. When in doubt, read the label. Been big discussions of this on a lot of older-vehicle boards. 1 Quote Link to comment
