I'm not a huge consumer of grease, and I primarily use this on bicycles. I refurbish old bicycles for a co-op and two main reasons I like this product, 1) high-temp so I can use on bicycle coaster brakes, 2) easy to use squeeze tube. I know I can buy tubs of grease for less cost per volume, but the convenience and ease of a squeeze tube is nice. I primarily use this on loose ball bearings, coaster brake rebuilds, on screw threads, and as a general multi-purpose grease. 1 star deducted because of what I think is a high price. A tub of Stay Lube marine grease costs $11/14 oz, but a tube of this is $15/8 oz. So in tube form, it costs 2.3x more. I probably use a tube a year, so not a deal breaker.

My Ford F150 truck has the driveshaft slip yoke clunk issue as the gears shift from low to high. I used many grease in the past that only lasted about a month. This grease worked for about 8 month. I am very happy with the results. I will be certainly buying more.
