Having sold your products for years in my positions with Pep Boys and CarQuest,and using the Oil Stabilizer and Fuel Treatment regularly,your true worth hit home recently when I needed a leak stopped in my engine. I drive a Cadillac STS with the Northstar engine and over the last year it developed a slight leak from the rear main.This past spring,it got worse to the point that I had to get it fixed.To no surprise as I searched for someone to do the job,I was met with outright refusals,and costs of over 1 thousand dollars! With an oil/filter change coming due (145K miles),I visited my local CarQuest and grabbed a bottle of the Engine Oil Stop Leak and added it to the change. Less than 400 miles later, NO LEAK ! Thank you Lucas for saving this unemployed car parts guy a bunch of cash! I'll contonue to support your products every chance I get.
