## Overview

Lucas Oil 40686 Heavy Duty Oil Stabilizer is a 355ml pure petroleum additive designed to extend oil life by 50%, reduce engine wear and heat, eliminate dry starts, and boost oil pressure. Compatible with all oil types and vehicle classes, it enhances engine smoothness, power, and fuel efficiency, making it a must-have for maintaining both new and aging engines.

## Description

Lucas Oil Stabilizer is a 100% petroleum product formulated to eliminate dry starts and reduce friction, heat and wear in any type of engine. It allows motor oils a higher degree of lubricity which reduces oil consumption and operating temperatures. Use Lucas Oil Stabilizer in gear oil to stop leaks, reduce operating temperatures and increase the life of the gear oil. Since it is pure petroleum, it can safely blend with all other automotive lubricants, even synthetics, ATF and mineral oil. It keeps old engines alive and new engines new. Use 20% of system capacity (example: 1 litre Oil Stabilizer with 4 litres engine oil). In badly worn engines use up to 60% of system capacity. Use in every oil change. In light duty manual transmissions use 25%. In heavy duty transmissions use 25-50%. To stop noise and wear in differentials use 50-100% no special additives needed for limited slip. In transfer cases, use 50%

Review: It works - Tried different makes of this additive—but this one works -definitely makes the engine quieter and smoother— also going by the oil pressure gauge does increase oil pressure
Review: Increased oil PSI - This product works as intended. I read many reviews before buying.
