This gear oil replaces Lubrication Engineers LE 607 Almasol (SAE 90) with the new Duolec EP/AW/tackifier additive and a synthetic blend (LE 607 was 100% dino oil with Almasol EP/AW additive) base oil. I really liked how 607 performed and was worried when they changed the formula. It looks like it will be OK though.

Previous two UOA's were LE 607. This sample was the first UOA and fill of 1605.

The drain plug had a very small amount of gray paste on it (magnet). The smallest amount I've ever seen on a drain plug. This fill had a small amount of residual LE 607, since I didn't flush the diff. I expect the viscosity will be a little higher if I do another UOA. I change the gear oil frequently (whenever the tranny fluid needs changed). It only has a 0.82qt capacity, so I figure it's good insurance.
