Hot Rod & Classic Car 20W-50 Motor Oil

Lucas Hot Rod & Classic Car Motor Oil SAE 20W-50 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 20W-50 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 (winter for example in some parts of the country) 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.

David McOwen uses Lucas Transmission Fix in 1998 Dodge

It took 5 months for my wife Debi and I to leave New Orleans after Hurricane Katrina but we finally sold the house and bought a house in Oklahoma. In January when I was pulling a 3,000 lb trailer with my 1998 Dodge Caravan I couldn't get past 55 miles per hour and I was burning gas up like crazy, motor running hot and noisy. At one station I noticed the Lucas Oil and Transmission treatment. First I put the Oil in and the Engine quieted right up (no more clicking valves) and the temp came down. Then I put the Transmission treatment in and got back on the road. It passed 55 easily and was able to cruise along at 70 without straining, stayed cool, quiet and decent gas mileage. Just this month I had a gas sensor problem where it would keep dropping to empty, low fuel light would come on and it would ding like crazy. I put the Lucas Fuel treatment in and the sensor straightened right out and hasn't given me a problem since. Like I said I am a walking Lucas commericial. Great stuff.
