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.

Lou Zaffos uses Lucas Transmission Fix for 1992 Old Silouette Van

Dear Lucas Oil,

I want to thank you for making a product that actually works! I have been using your oil additive for 7,000 miles in my 1992 Old Silouette Van. The oil pressure which was always sitting right above 0 at idle is now back to where it was when the engine was new.

Recently I was having some transmission trouble. The car has 168,000 miles on it so I just figured it was time to turn the car in. While at the auto parts store I noticed your transmission product. While my transmissionwasn't leakingit was shifting hard and grumbling and growling and locking itself out of the 4th gear and overdrive. Half the time recently I was starting out with four gears and finishing my drive with three. While figuring there was nothing to lose I figured I would give it a shot. I mean...$8.00 is better than $2,000.00 for a re-built tranny.

This past weekend I drove it 330 miles. And the amazing thing to me was every mile I drove it got better and better! There is still an occasional growel during a downshift up a hill BUT I can't believe the fact that this tranny is running and shifting like new. I immediately went out and bought three more bottles for my other cars.

Do you guuys have some stickers that I can put on my van?

Thank you again for makin
