Synthetic 50 wt. Transmission Oil

Lucas Synthetic 50 wt. Trans 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 sulphur and phosphorus as a total anti-wear package. We at Lucas Oil Products consider this inadequate. Most heavy duty truck transmission manufacturers now consider sulphur 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.

Victor Stacy uses Lucas Transmission Fix for 1997 Chevrolet Conversion Van

Dear Sir,

In December 27, 2002 I left Lynchburg, Va. to go to the Continental Tire Bowl in Charlotte, North Carolina. I have a l997 Chevrolet conversions van approximately 60,000 miles. When I was leaving the Tire Bowl heading home my transmission started slipping.

I took an offramp and got on a side street, by that time the transmission had completely went out. I let it set for a few minutes while trying to get assistance. Then I started back up and was able to drive another 1/2 mile and the transmission went out again. I asked the guy at the service station to change the fluid for me. I then went to Advance Auto and bought a bottle of Lucas Transmission Fix.

The man at the service station said it would never work, but I drove the van home to Lynchburg, Va., approximately 200 miles.

I still had to have a new transmission, but as least it had gotten me out of a bad fix. Now when I change fluid, I put Lucas products in my vehicle.

Thanks for a product that really works.


Mr. Victor Stacy
