Rear Differential Oil

[libertybellcdr]

Which type of oil is designed to be used in the rear differential?

Ezgo recommends 30wt oil for the Dana rear end in your cart. You can use an equivalent synthetic oil too.

I'm confused. The EZ-GO Textron service manual, 1989-1993 (Marathon) says to use SAE-80-90 oil, 8-10 oz. (see page S-14). I have the Spicer-Dana rear end in my 1994 Marathon.

Should I be using 30wt or 80-90 wt?

30 weight engine oil has the same viscosity as 80-90 weight gear oil. You can use either one, but if you use motor oil make sure it is non-detergent oil.

It's that the same oil I need to use in my 2008 TXT?

Yep. EZGO hasn't changed the rears.

This is easy to remember for both gas and electric differential oil requirements;
Of the 3 major makers, EZGO, Club Car, & Yamaha, only CC gas carts use 80-90 gear oil. All the rest use 30wt motor oil in the differential.

Unless you have an EZGO electric with limited-slip differential. Then it's 25oz Mobilube HD85W140 and 2oz of friction modifier.

My owners manual (2000 TXT) says SAE 30. Some on here are using synthetic.

So how do you know if you have a limited-slip differential?
