2006 PONTIAC GTO LUCAS HEAVY DUTY 85/140 GEAR OIL

I was having problems with my limited slip differential. I could not get both wheels to spin at the same time. I kept getting "one wheel peel". I put some of the 85/140 gear oil in it. Now I can get both wheels to hook up with no problem. It is also very quiet now. All of the Lucas products I have used do what they say.
