does anyone know what the correct diff oil is for a 98 viper cheers craig

[ViperDave]

97 diff oil which I'm 99.99% certain is the same, is synthetic SAE75w140 + 4oz friction modifier.

here are the Chrysler's part numbers and prices from last year

C05103524EA 021D06 oil Power Ste £3.52 = Power steering fluid
C05103526EA 021E03 Lubricant GEA £18.31 = Diff oil
C05103522EA 021E02 Addative Axle £4.49 = Friction modifier
C04874459EA Lubricant Transmissi £25.73 = Synthetic trans oil
C04267020AB 004C05 Antifreeze 3 £9.86

but then it wouldn't be the correct diff oil. I guess you take you chances with any reputable 75w140 synthetic gear oil, either with the additive included in the oil or add it also.

some rave about royal purple (which i understand includes the additive) others talk of redline and mobil 1, but i have also seen negative posts about both in relation to viper transmissions. I guess once someone goes outside of the mopar stuff, any diff problems get blamed on not using mopar oil, with mopar oil in there a diff problem is viewed as diff problem not an oil problem so who knows whats really best.


You really don't have a main dealer Chrysler nearby?

ps annoyingly you will also need just over a qt of the stuff so you have to buy two bottles and only use a fraction of the second one.
