I added Lucas Oil Stop Leak about a month ago and what a difference!
I have a 2004 chevy cavalier with 304,000 miles which is my work car. I usually have to add 1 quart of oil every 2 weeks. I commute 80 miles a day back and forth to work. I added Lucas Oil Stop Leak about a month ago and what a difference! I have only needed to add a half of a quart oil since adding that. I will continue to use the Engine Oil Stop Leak with every oil change from now on!! AWESOME PRODUCTS!!! Tested, proven, and effective!!
