Excellent oil for Harley Davidson 6 speed transmissions, much smoother shifts.
I brought the diff oil a couple of weeks ago, changed the oil in my differential..Seems to work quite well..Recommend Penrith for any oil change
Before I put this in, the mighty AU was struggling to do skids. Now I put this in and my open diff does double pegger massive danga burnouts. Good value.
Perfect product packaged well easy to refill with pullout filler tube The oil in my car was black I had just bought it and this was recommended for my VS Ute . I was a bit concerned that it seemed thinner and I might wind up with a little diff noise But none at all..in fact after a run it actually runs cooler with no a peep from the rear endHighly Recommended Oil will use it again AAAAA+++++
Reduces the noise during gear shifting. Makes shifting smooth.
I brought this on special instead of my usual Castrol brand. After use it appeared to have emulsified in my bikes final drive. Changed back to my usual Castrol brand and no problems. Would not recommend this product.
I bought 2 litres to use in my new Nismo diff during the 1,000km break-in period. Virtually identical specs (weight & friction characteristics) to supplied ‘factory fill’ 75W140 100% Synthetic Differential Oil by Motul. Penrite oil drained and inspected after break-in period and had done its job perfectly.
My diff was binding so thought better get some new oil. Binding has stopped feels smooth now. Vy clubsport
