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.

Kevin Fox uses Lucas Fuel Treatment for 1994 Chevy S-10

I have a 1994 Chevy S-10 with a 4.3L V6. It was running a little rough and the dieseled badly when the engine was shut off. I ran a bottle of your gas treatment thru 3/4 of a tank of gas. As soon as I left the gas station and was driving off the truck got a sudden burst of energy. By the time I had made it down the roadabout 4 miles the truck was running as smooth as a sewing machine and the engine shuts off as it should.

I was so impressed that I purchased several bottles and gave one to my younger brother who is a police officer. He ran the bottle in his patrol car. He stated that he knows his cruiser reaches over 100 mph. Because the car is running so rough it feels as if his engine is coming apart. After adding the Lucas fuel treatment he was in a pursuit in less than three hours. He said he looked at the speedometer abd was passing 120 mph and it was still running smooth.

Since these experiences I have switched to Lucas to several applications such as the gas treatment, Oil Stabilizer, Red and Tacky grease and your gun oil.

Thanks for such a great p
