600 gear lubricant

A lot of people I know swear by the Lucas products. It's new to me but I'll try it. I've been told once you add it, it is always there. I remember years ago a company by the name of BG products had salesmen going around demonstrating their product. They had a machine that they'd put a common brand of engine oil on a turning shaft and then bear down on it with a flat bar stopping the shaft with the force they would apply to it, smoking hot. Then they put a smear of their product on the shaft and ask us to try and stop the shaft as they demonstrated earlier. We'd get the bottle of STP and it worked the same as their product. :D
 
Anyone remember the STP screwdriver test? The one where the salesman dips a plain flat screwdriver tip in STP and then asks the customer to hold it by the tip w/the handle down. W/the taper of the screwdriver blade and the sliptivity of the STP it always slips out.

I remember it - but STP is NOT a lubricant.

So I keep hearing.

****** filled 100 percent with non-lubricant, I guess.

Doesn't STP contain some ZDDP to add back into the engine oil, which should help with all that's been removed these past few years?
 
If I remember correctly STP [ Scientifically Treated Petroleum] does contain zinc. But it isn't a lubricant. When Studebaker owned the company we were supposed to try and sell that stuff. The only good thing I've found for it is engine or gear assembly.
 
A commercial about a "miracle" additive told how it helps an AUTOMATIC trans work well, but their CUTAWAY showed a MANUAL TRANSMISSION?????
What a bunch of BUNK!!!---It's all about that everloving BUCK!!
When I was a kid, we had that poopy BLACK medicine, that CURED anything, OH, the marvels of SCIENCE!!

I use the 680 product in my Transmission, Differential, and Steering Box. I love it. It quickly slows the Transmission gears when coming to a stop...
 
Lucas oil stabilizer is a wonderful product for transmission/differential. Makes gear shifts silky smooth. Very noticeable difference over the 600W.
 
Roger Kauffman, the MARC technical advisor for many years, stated several times that he ran 100% STP in his transmission and rear end. He drove his cars a lot and had no problems, and when he checked his trans after 1000's of miles, the STP was as clean as the day he put it in.
I took that to be a pretty reliable real world test.
check his comments out on the MARC archives.
