Review on Lubegard 30903 Gear Fluid Supplement - 8 oz. - Boost Your Vehicle's Performance! by Travis Vasquez

Update Oct 2018: Benefits I noticed stuck with the F250 when I had it (no longer) and I also used it in a new application: Ram 1500 2016. I chose Redline 75w140 and this product as advertised. The axis worked as I expected; very quiet. The engine is also from LG and this truck drives great. The average mpg per 24,000 miles is 19.9 combined. Not bad for Hemi! I have used this product on my Ford F-250 on two separate occasions; 4-speed manual gearbox and rear axle. Using this product mixed with 80w90 in a manual transmission has greatly improved shift quality, especially in cold weather. I also added a bottle to the Dana 70 limited slip rear axle. Used Valvoline 75w140 oil (contains a friction modifier) and a bottle of Gear additive. No problems after 500 miles, axle is quiet, no knocking. Lubegard isn't the only reason the axle is quiet, but it's one of the reasons I think. The LXE technology that Lubegard uses has an amazing effect on reducing friction. I have successfully used Lubegard products on engines, automatic and manual transmissions, axles, coolant and power steering. Use this product with confidence.
