best diff oil

[rx7london]

im just about to fit my diff on my fd wondered what was the best type of diff oil to put in it and how much will i need thanks

For gearbox and diff we recommend Silkolene Syn 5 75w-90.

You can also use Silkolene Boa 90LS for diff only applications.

I usually use Redline Heavy Duty Shock Proof for the diff and g/box.

i used 20-50 engine oil should be alright yeah guys

Engine oil is not the right stuff. Get it replaced asap if you want it to last.

Indeed, 10w-40 is closer to the mark
