Synthetic 50 WT Transmission Oil

Lucas Synthetic 50 WT Transmission Oil is designed especially for heavy duty truck transmissions but can be used in many other applications.

Common gear oils are mostly base stocks with little more than an addition of sulfur and phosphorus as a total anti-wear package. We at Lucas Oil Products consider this inadequate. Most heavy duty truck transmission manufacturers now consider sulfur and phosphorus to be potentially corrosive to copper and brass and consequently recommend against common gear oils for this reason. The other 50 WT we have tested, synthetic or otherwise, are pure base stock, we consider this also inadequate.

Lucas Synthetic 50 WT contains an exclusive additive concentrate derived from synthetic oil that ensures lower operating temperatures and better lubrication, especially to upper bearings and gears. This is a long lasting fluid that is far superior to conventional synthetic fluids and contains nothing that could be harmful.

Meets or exceeds API MT-1, Eaton Transmission Div., 164 rev 7, Mack Truck TO-A Plus, International Truck TMS 6816 and other applications requiring non-EP Lubricants.

Lucas hi-mileage stabilizer IMMEDIATELY quieted engine

2003 F150 5.4L Triton 3-valve. Timing chain, guides and cover had disintegrated at about 280,000 and constant oil leakage. Put new chain, guides, oil strainer, pick-up tube etc and drove to 345,000 using 20w50 and losing about 2 quarts a month. Noisy upon start-up which I understand is typical for these Tritons plus lifters made constant noise. Was about to install a new/used motor when I figured what the heck try a bottle of Lucas hi-mileage stabilizer. IMMEDIATELY quieted engine and after adding another bottle a week later, engine is running QUIETLY!!! leaks less too. Have installed new coil packs and I think this 5.4 might just make it to 500,000!! I also added 1qt to the tranny...shifts smoother.

I would recommend Lucas products to anyone with a diesel…

I have been using Lucas products in my 2001 Ford diesel since new with much success, it has over 250000 miles and going strong. I would recommend Lucas products to anyone with a diesel.

Try out the Motorcycle Oil Stabilizer you’ll hear the difference…

My Harley always had the top end tick like most bikes do. So I decided to purchase the Lucas Motorcycle Oil Stabilizer. Wow I can't believe how much this has helped granted it's still makes noise but it dampens it down alot! I run Lucas Synthetic 20w/50 in my motor with Lucas Gear Oil in my trans. And Lucas primary oil. I don't care what anybody says Lucas makes some great oils! Try out the Motorcycle Oil Stabilizer you'll hear the difference it made a believer out of me and it will you too!

It was like riding a completely different bike.

I have a 2008 Harley Dyna Street Bob which has been completely customized to include engine work, custom exhaust and multiple dyno tuned sessions. The motor has 31k miles on it. The engine has always run extremely hot and destroys any oil thats in it in less than 2000 miles. This past weekend, I decided to switch over and try Lucas Oil and added 6 oz of Motorcycle Oil Stabilizer to the fresh oil. The bike is extremely quieter now (always had a sewing machine noise) and runs significantly cooler. It was like riding a completely different bike. I am sold. This stuff rocks.
