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.

Matt Druyor uses Lucas Heavy Duty Oil Stabilizer in 2001 Oldsmobile Intrigue

I own a 2001 Olds Intrigue which currently has 118,000 miles on it. I purchased it in 2003 with 25,000 miles on it, no problems. Obviously, this car has been DRIVEN. Michigan's climate is known for excessive wear on engines and with the car being driven to Florida and back 5 times, I can say the engine is broken in. A friend reccommended your fuel treatment when I was having injector issues and in just two tanks of gas, the hesitation stopped. I then started to use 1 qt of the oil stabilizer in every oil change. Being the car takes 6.5 qts of oil, someitmes I use 30/70 Lucas/Oil and I must say that your product is amazing! The car starts on the first try cold or warm, does not burn ANY oil and still feels like it has all 215 horses. When I put synthetic oil in, usualy every 3rd or 4th oil change, I use the synthetic stabilizer- even though the 3.5 is known for "using" oil, I still have a full crankcase at every oil change. I will put your products in every vehicle I will own in the future.
