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.

I am a parts salesman for a living and build engines on the side. I am so impressed with your products, if you are ever able to make them better i would love to see it. we use your oil and stabilizer in demolition and circle track engines and it is amazing how much temperature and fuel dillution they can take. It sticks so well to the parts, i can pull an engine apart on a sunday and if its apart all week its still drips out on the next sunday, thats amazing. Your transmission stabilizer is amazing also. We once built a demolition derby car using an old transmission that wouldnt even pull itself onto the trailer as we went to load it for a derby many hours away. we dumped two quarts of the tranny stabilizer in and it is still running to this day. one year ago i pulled a 350 chevy tranny apart that had 26 demolition derby's on it and the first and reverse clutch pack had absolutely no friction material left on them, but this tranny still worked very well and never got hot nor were the plates welded together, it amazed me. i am yet to use a product of yours that i was not amazed by, keep up the good work thanks.
