DON'T use it...I used it in a hi mileage V6 and it jumped time a week later. They refused to pay for having it fixed, but I know it was the SLICK50!
If you want an engine clean, just do a kerosene clean. At oil change do 2 qts oil/2 qts kerosene and run for 10 min at
LOW RPM's. Then drain and refill w/ good quality oil. But you have hi miles, and it may remove deposits that are "beneficial" to an older engine. Good Luck!
