Great product
Exactly what I was looking for

Finally a better option from Merc!
Extreme Perf lube is Merc's answer to finally have a decent product to protect Bravo 3 outdrives. Their previous "high perf" lube wasn't up the the heat/pressure generated by the B3. Here's hoping they don't cheap out again!

High quality product at a much more reasonable price than the Mercury name brand.
A week before launching our boat I noticed the outdrive lube was a little low. Having this delivered so quickly and being able to get it at such a better price than the Mercury brand was really nice.

Extreme Performance Gear Oil
This is the only gear oil that I trusted in my Bravo outdrive. The drive never ran hot or discolored the paint, and never needed a drive cooler added on our Baja Twilight Cruiser with the coupled 7.4 Mercruiser. Now itโs the only oil that I trust in my new Mercury 300R gear case.

Fresh oil annually
Good oil for the drive. There is an oil one step above but was harder to acquire in a short time frame. Worked just fine in our Bravo 1

What I needed!
Was what I needed for Mercruiser outdrive. Order 2 though. It takes more than a quart.

Hard to find stuff
This was the viscosity noted in my new 3 point tiller's manual. I checked half a dozen farm, tractor, auto and hardware stores but nobody had it. Not wanting to void the warranty, I figured I'd check Amazon and there it was. Not only that but it was next day (Sunday) delivery.

Best lower oil
I change the fluid in my Mercury 2.5 200hp every other year. This is the only fluid I put in there.

This is a US quart which is much smaller than a UK quart.
Should have read the advert line by line and zoomed in on the picture of the label. I ordered this of Amazon.co.uk and paid in ยฃ and where I come from (UK) a quart is 1.14 litres. This is a US quart which is only 0.946 litres. I got less than 3/4 of the amount I expected. Can't fault the product, but selling in a UK market with US units is misleading. Disappointed.
