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.

David Dower uses Lucas Transmission Fix for 1994 Chevy Blazer

Hey Folks,

I just wanted to drop you all a line to tell you how wonderful I think your products are and what a difference they have made for my vehicle. About a year ago, my Uncle in Florida told me about Lucas and how much better the engines run in his car, trucks and boat. I was a little skeptical at first, but when he told me how much of a difference it made, I thought what the heck, and gave it a try. Especially since one of his pick-up trucks has over 280,000 miles and is still running smooth.

I drive a 1994 Chevy Blazer myself and always kept up with the maintenance since it was brand new. Anyway, I let me Uncle put the Lucas Oil Stabilizer in my blazer last year and WOW! I noticed a difference almost immediately. I mean, it almost felt like a brand new engine. It ran smoother and quieter and even seemed to lose vibration when I drove at higher speeds. Also, I used to have a slight oil leak, that went bye-bye over a period of time. Now I have been using Lucas Oil Products for about a year now and it seems my Blazer is running better and better with every oil change I make! I also started to use your Fuel Treatment and your Transmission Fix. I LOVE IT ALL!

I just went over 155,000 miles on my Blazer and who knows, maybe if I keep adding Lucas Oil Products to my engine, I'll get another 155,000 miles easily! Keep up the good work and I will continue to spread the word around here in the Mid-Atlantic States!
