Hot Rod & Classic Car 20W-50 Motor Oil

  • {irecommend}

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.

Ron Rich loves Lucas oil Stabilizer

Can I mix my oil/Lucas at a 25/75 mixture? I have a big block that has worn cam bearings. My oil pressure drops to almost nothing at a warm idle. Is it possible to have 100% Lucas and run it?

Ron,

Thanks for looking to Lucas for solutions. The maximum we recommend is 60% and I think I'd start with a 50%/50% mixture to start with and then if need be go the extra 10% to 60%. The 50/50 should give you excellent results. If you're not seeing improvement at this level it's quite possible that this motor has met the end of the line. Thanks again, John Mingus

John, I did it!! I used the Lucas oil stabilizer before going four wheeling. I was really skeptical at first. I went ahead and bought 2 gallons to mix with all my diffs and boxes and motor. John, I stayed in the woods all day long. My '87 K5 with a 454 bored .60 over with only a three core radiator stayed cool; whereas, the day before, it had gotten extremely hot in downtown traffic. John, the oil pressure stayed above 25psi at a warm idle all day!! Remember what I told you about my oil pressure before? Well, evidently it was just a lifter that didn't want to pump up. It pumped up right away with the Lucas. I just could not believe it!! I'm telling everyone! I was just so worried about my motor before trying Lucas.
