Compatible with all oil types and suitable for engines, gearboxes, differentials, and transfer cases, it’s the go-to solution for maintaining both new and worn engines with universal fitment. ## 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, aft 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%. ## Features - Increase oil life at least 50% longer - Reduces oil consumption - Eliminates dry starts - Raises oil pressure - Increases power and miles per gallon ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B07W6G46XC | | Automotive Fit Type | Universal Fit | | Best Sellers Rank | 44,643 in Automotive (See Top 100 in Automotive) 67 in Engine Oil Additives | | Brand Name | Lucas Oil | | Compatible With Vehicle Type | Car | | Container Type | Tin | | Customer Reviews | 4.6 4.6 out of 5 stars (548) 4.6 out of 5 stars | | Included Components | 1 x Lucas Oil Heavy Duty Oil Stabilizer - 1 L | | Item Type Name | Heavy Duty Oil Stabilizer - 1L | | Item Weight | 0.92 Kilograms | | Liquid Volume | 1 Litres | | Manufacturer | Lucas Oil Products Inc | | Manufacturer Part Number | 40001 | | Manufacturer Warranty Description | No Warranty | | Model Number | 40001 | | Number Of Packs | 1 | | Size | 1 Liter | | Unit Count | 1000.0 millilitre | | Upc | 049807110499 | ## Product Details - **Brand:** Lucas Oil - **Liquid volume:** 1 Litres - **Package information:** Tin - **UPC:** 049807110499 - **Vehicle service type:** Car ## Images ![40001 Heavy Duty Oil Stabilizer-1L - Image 1](https://m.media-amazon.com/images/I/71xAfL7ATgL.jpg) ## Available Options This product comes in different **Style Name** options. ## Questions & Answers **Q: What’s the Difference between Lucas 90001 and 90004** A: i use the heavy duty for all applications, but i dont know the difference, assome to do with engine loading, or high temps, eg a lot of motorway driving. hope it helps. **Q: hi i have a Sorento crdi 2.5 this is my first diesel is it ok to use and would you flush the engine before oil change ..** A: Flush if pos but can be used as is quieted my jag. Down **Q: Is it ok for diesel engines** A: Yes you can use this product in diesel engines. For newer diesel engines using a 5w-30 or 5w-40 the Synthetic Stabilizer 10130 would be better. **Q: Can you use for hybrid car** A: No, this product would be far too viscous for use with the light weights oils used in hybrid cars. For 5W- oils use Synthetic Oil Stabilizer (#10130) for 0w- Oils use Low-Viscosity Stabilizer (#41097). ## Customer Reviews ### ⭐⭐⭐⭐⭐ Greatest oil stabilizer there is!! *by on Reviewed in the United Kingdom 20 June 2025* Greatest oil stabiliser on the marketBeen using it over 20+ years on a variety of vehicles and have spent little to no time on breakdowns and relatively impressed with it in engines gearboxs and diffs ### ⭐⭐⭐⭐⭐ GOOD *by on Reviewed in the United Kingdom 16 November 2025* GOOD ### ⭐⭐⭐⭐⭐ It 100%Works *by on Reviewed in the United Kingdom 16 November 2024* Bought this product and wondered if it worked as well as it said , So got the product and followed the simple instructions on use. I removed a litre of oil then added the litre of Lucas oil. Ran the engine for a while then left it till next day. As if buy magic the engine had no start up rattles and sounded so much quieter.
