What’s the Difference between Lucas 90001 and 90004

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.

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 ..

Flush if pos but can be used as is quieted my jag. Down

Is it ok for diesel engines

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.

Can you use for hybrid car

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).
