Your cart is empty.Gear oils have needed improving for years, especially in the hi-performance industry. The Lucas 85W-140 gear oil enjoys the technology Lucas developed in making the "Lucas Heavy Duty Oil Stabilizer", the number one supplemental oil in the heavy duty industry. This formula is fortified with special anti-wear agents and lubricity agents to control wear and drag as well as special additives to control heat. This feature is not found in ordinary gear oils. This gear oil is both excellent for race cars and any heavy-duty application where plain gear oils just aren't good enough.

I use Lucas products in EVERYTHING! From gear oil to power steering and brake fluids to fuel treatments. It's in my bikes, my off road toys, my hot rods and my daily drivers. You just can't go wrong with Lucas! BUT I wanted to correct one thing on the ad. It is NOT made in China as is listed in the details section. I'm happy to report that as of the time I posted this(09/01/24) it IS still Made in USA. To some of us that matters

Excellent for heavy duty use such as Quad gearboxes and differential, and also keeps the noise down that is produced by these parts.

What can I say... It's gear oil. I trust the Lucas Oil brand, and, the price is great. Nice to have some of this on the shelf for top-offs, etc. I used this in my Toyota Tundra differentials. I also blended about 25% of the Lucas Synthetic Oil Stabilizer while I was filling them. First time doing this "blend", but since I accidentally bought the Stabilizer (I meant to buy Lucas Gear Oil), I decided to add some in. I can't really tell a difference, but it's reassuring to know there is fresh, high-quality oil in there!
