Synthetic 50 wt. Trans Oil

Lucas Oil Products, Inc.

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.

Al Santos uses Lucas Transmission Fix for 1993 Ford Explorer

I wanted to tell you how pleased I am with your Trani=mission Fix. I have a 1993 Ford Explorer that has 157,000 miles on it. I just put in a rebuilt automatic transmission 2 months ago, when last night it suddenly dumped most of it's transmission fluid out the front pump oil seal while idling in the driveway. It would not move forward or backward. I was really suprised, but I know these transmissions have issues with oil pump seals.

I figured the seal was probably not damaged , but had probably lost it's seal at one edge. I thought aboout what a lot of work it would take to get the tranny in and out of there, having to fix the problem and missing a few days from work. Iwent down to the local parts store and askedwhat was the best transmission leak sealer., and they pointed out the Lucas Transmission Fix. I bought the Lucas Transmission Fix and poured it in the filler tube, started it up, and then poured in 4 quarts of ATF, and NO LEAK!

I drove it to a short test drive and it drove and shifted perfectly. I was estatic! Toda I drove it to work and back on my usual 55 mile commute to work with no problem.

Lucas has really saved me a LOT of TIME and TROUBLE. Thank you so much for makingan excellent product that works so well and so quickly. I will be recommending Lucas Transmission Fix to everyone I know because everyone ought to know about Lucas. I will try using all the other Lucas products

Thanks again,

Al Santos
