I have never used the tranny stuff but I can honestly say the Lucas fuel treatment is great stuff. Made my moms old car run like new after a couple tanks. Car hadn't had that much ***** in years before using it.

 

Lucas fuel cleaner and tranny treatment are apples and oranges. I personally like redline fuel cleaner.

 

Most Diesel guys I know swear by Lucas. I have only used their gear lube in the race car before I got my Royal Purple sponsorship. The lube held up well in the quick change,and never had any problems. The only additive I use and continue to use is Seafoam.

 

Yes it is but since Lucas and additives in general we also brought up I figured I would comment on Fuel treatment. Never tried Redline. I know what Lucas will do.


As far as Lucas and diesels. Their oil stabilizer is the #1 additive used by the heavy duty truck market. I sell lots of it where I work. Never heard much bad about it.
