Lucas Oil 10688 Details
Lucas Hot Rod & Classic Car Motor Oil SAE 10W-40 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 Engine Oil SAE 10W-40 is for muscle, showroom, classic and trophy cars without catalytic converters. It can be used in racing applications. Not recommended for passenger car use.
- Contains the high levels of ZDDP (Zinc) necessary to protect flat tappet cams, lifters, and pushrods
- Provides excellent thermal stability in case of overheating
- A true long lasting performance lubricant
- Contains special Lucas additives that protect against rust, corrosion, and dry starts associated with long periods of non-use

Can't find it on a shelf near me, but it's a great oil for flat tappet engines. It improved my oil pressure a bit over conventional 10w-30 that was in the car, sounds quieter too.

Been using this for a while, upped my oil pressure over conventional 10w30 and actually noticed a slight decrease in consumption in my 43yr old 350.
Would Recommend
I will definitely be ordering again in the future

I bought the Lucas oil for my 70 Challenger because of the high zinc content. Speedway motors had the oil in stock at a good price. I will be buying again from Speedway in the future.
