Lucas Oil???

Bah!

It totally crapped out my saab's motor. It ran funny then for some inexplicable reason the oilpan drain bolt blew/shot out. Thank God the threads were still ok. Took 2 more oilchanges to get rid of it so it ran right. The lucas trans stuff gummed my T-5 and that took 2 changes to get rid of it. The t-5 went from grinding to REALLY grinding.

Dont put this crap into your engine.
 
The biggest worry with this oil stabalizer stuff is

#1. How does it affect the defoaming agents in oil?

#2. Will it seize/gumm up your oil pump?

I'd stay away from this stuff and just run a heavier oil. Say 10W-40?
