Tom used Lucas Engine Oil Stop Leak to fix a rear main seal leak on his Cadillac STS

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.
