I have a '95 F150 ext cab 4X4 with 220k kms that runs very well, but will be changing rear end oil as I will be travelling out of town this winter and wanted fresh fluids and filters throughout the vehicle. The full tuneup has been done and rear oil is the last thing to do. The truck has a 8.8" limited slip with 3.31 gear ratio. I bought 4 litres of Heavy Duty Hypoid limited slip 80w90 gear oil and 1 litre of Lucas Synthetic oil treatment additive (good for limited slip). Will this be good for the oil change or do I need another type/weight of gear oil ?
Any info. appreciated !

 

That sounds good to me.
