Schaeffers 170 Extreme Performance Full Synthetic Sae 75w-140-1 Quart

Picked up an extra mile and a half a gallon on average and my diff definitely runs cooler. No need to to add friction modifier for limited slip either. Great product.

Oil great quality good. Seller is awful received a bottle with a leak in it and seller wouldn't replace it. Paid over $27.00 for it and it should be a full quart bottle. Seller also known as CNC Motor Sports

Schaffers oil is good stuff. Did will in my SUV transsvercas it rolls much beatter down the road .

Everything Scaeffers makes is top shelf. This no exception. Used their products for 40 years.

Installed in my 88' F350 with no adverse results (so far). Good stuff but wish they'd sell it in bulk locally!

Pricey but it's the best there is.

This is the only gear oil I will use in my 2015 Harley Davidson breakout.
