i dont use additives of any kind there a wast of money i think

"lol that is hilarious. Im never going to try it. just like that oil stabilizer stuff that Lucas oil has out""

Well I can Not say anything bad about lucas... I work at a Diesel mechanic shop. and We use alot of lucas in diesels engine lots of truckers belive in it and once you pull diesel engine you can see the bearings are coated and it really does stop/slow leaks..

could be becase its a diesal... but I cant see a differance

I dont know about using Lucas oil in a diesal but my friend put the stuff in his honda (<-that might just be the problem lol) and it started knocking. im not sure why. we did not investigate but Ive been told that the lucas oil stuff just makes oil thicker and stickier. I know alot of drag racers and i have never heard of anyone putting the stuff in a drag motor.

Z-Max didnt do a darn thing for my 88 SS. However, the Lucas stuff is GOOD STUFF! Their fuel stuff i use at every oil change gets me about 1-2 MPG. Ive also used their tranny stuff in my 88 SS, held my little 200-4r together for about 2 months of daily driving with the 1-2 band going out, lasted for a while. I trust Lucas items.
