Castrol12612 HYPOY C GEAR OIL

Happy to find this gear oil, shipped quickly and at a reasonable price. Must have for older classics cars.

Great product and great price around. Was having hard shifting issues and missed gears in my 85 BMW k100.... 850 ml. It this dude me right up... Smooth shifts now.

New name for the old Castrol Hypoy C. This non-synthetic oil is strongly endorsed by some of the old BMW motorcycle mechanics for transmissions and final drives, both the airheads and oilheads. I change the oil (80W90) every 20,000 miles in both the tranny and FD.

I use Castrol Axle Limited Slip Gear in my Subaru I wouldn't use anything else!! The product is wonderful I just put a new engine in my car and I was so happy to find it!!

Fixed gear lockout in an old 5spd trans.

Seems to work well in my posi rear end.

Good product.
