Limited Slip Diff Oil

Hi

I've been a busy bee lately (fitted a new cooling fan and upgraded the brakes), I'm on a roll and don't want to stop now.

I'm going to change the oil in my Suregrip diff, does anyone know what type / grade of oil I should use and and would it require any limited slip diff oil additive?

There are oils specifically for LSDs,bought some years ago Duckhams DL90,so you shouldnt need any additive.
This may not be correct for a Mopar though.

Thank you for the feedback. I found this site on the internet which gives some information on Mopar rear axles

http://www.extrememopars.com/dodgerearaxles.htm

but when I searched for the part number (2585318, special sure-grip lubricant) for it's modern day equivalent, I couldn't find anything. Duckhams DL90 also doesn't seems to be available any more.

Still searching, I'll let you know if I find anything.

I used the readily available GM equivalent limited slip diff additive (called a friction modifier)and had no problems at all...I got mine from US Automotive in Bedford.

Don't know how the price compares with others.

Hi Moparfolks.

Mopar still sells 'friction modifier' for Jeeps etc.
One bottle per diff is just enough for two litres, but play safe and use two!
Comma Oils still make LSD oil and is still available in good Car-parts shops.

Bacca.
