If you are using a good oil and changing it regularly there isn't any benefit in using the Lucas. Hell, if you are using a cheap oil and not changing it regularly there isn't any benefit in using the Lucas.

 

fuck lucas. its over priced junk.

Schaeffer's Moly EP additive is $4 well spent. Im pretty sure you could run w/o oil on that shit.

 

What got me thinking is a comment from a local tractor puller. http://74.54.199.34/~boyd/greenstreak/index.php?pull=res_details&id=73 IIRC, They were having problems spinning bearings and someone sugested they try the Lucas stabilizer. Boyds started useing it and a bond was formed between the two companies. Soon Lucas was sponsoring Boyds. And the rest as they say, is history. That is the story I was told anyway

Lucas is very slippery. It works the opposite of seaform or other toluene based cleaners which clean out the varnish to free parts such as stuck piston rings. It works more like penetrating oil, loosening stuck parts by lubricating them.

I've had too many positive experiences with Lucas products to list them hear. So suffice it to say, I use it along with off road 15-40 diesel oil in my GTO. The offroad diesel does not have to comply with 2007 standards, thus it contains much more zinc, a major antiwear additive.

As to moly additives, they are slippery too, but do not help raise the viscosity shear point. With Lucas you gain the slipperiness while also raising the shear point.

 

The only issue I would have with Lucas is that it doesn't have any anti foaming agents in it. Other than that it is good stuff.
