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.

Jeff Skrukrud uses Lucas Transmission Fix for 1994 Chevy Blazer

Hello Lucas Oil,

I just wanted to drop a quick line myself about your Transmission-fix. I own a 1994 Chevy Blazer and a 1993 Chevy van and used your transmission fix on both. I was skeptical at first thinking this was going to be another downfall or wasted money. Boy what a difference. My Blazer was slipping here and there but after adding the transmission fix, I no longer have the slipping problem. The van had the same and I mean "HAD" but it too shifts like a new transmission was installed. This was the best money I could have ever spent. Its better than spending $1500+ to get your transmission overhauled.

You have me sold on your products and I will use the products again and again. I definitely say that your products saved me a lot of money and headaches.

Thanks again,

Jeff Skrukrud
