Hot Rod & Classic Car 10W-40 Motor Oil

Lucas Hot Rod & Classic Car Motor Oil SAE 10W-40 is manufactured with the highest quality paraffinic base oils and is fortified with a unique additive package containing high levels of zinc, molybdenum and phosphorus, which provides a tougher, thicker additive film for maximum protection even under the most severe conditions. It lowers oil temperatures, extends oil life and minimizes metal fatigue. It improves the film strength between the cylinder wall and piston rings and slows oil burning and improves pressure in worn engines. It has good cold temperature properties and stands up to high operating temperatures. It is compatible with methanol and all racing fuels, as well as with synthetic and non-synthetic oils.

Lucas Hot Rod & Classic Car Motor Oil SAE 10W-40 is for muscle, showroom, classic and trophy cars without catalytic converters. It can be used in racing applications. Not recommended for passenger car use.

Available in convenient 5 quart bottles, the formulation is perfect for the Hot Rod and Classic Car crowd with an increased zinc value of 2100 PPM. Because many of these very special machines often spend long periods off the roads, a number of the components of the additive package used in Lucas' Marine oils to provide rust and corrosion protection have been included in its unique formula.

Steve G's fixed transmission issues on his 2006 S10 with 150K Miles with Lucas Transmission Fix

I use Lucas Products in all my bikes. But, I want to tell you about my shop truck. In 2006 I bought a S10 pickup for the shop and to pick up bikes. It had 80,000 miles on it, 2.2l with a 5 speed. Shifting wasn't crisp and 3rd gear howled badly. Replaced transmission oil and still had noise. I replaced fluid again but this time added 50% with Lucas Sythetic Stabilizer. About a week later was driving around and noticed shifting felt crisp and could actually feel detents like a new truck and noise was somewhat quieter. A month later noise was gone. 5 years later and 70,000 more miles it still feels great and still quiet.

Thanks Lucas.
