Gary Arnold uses Lucas Heavy Duty Oil Stabilizer for 1993 Dodge Dynasty

To whom it may concern,

I have been using your Lucas Oil Treatment in my 1993 Dodge Dynasty since it turn over 100,000 miles (this is when I found out about it). My car now has 220,000 miles on it and is still going strong. It does not smoke or burn any oil, but it leaks it. In the winter time the engine may sound like a diesel in the morning, but within a few moments it quiets down.

I am planning on making a trip down south (about 1700 miles) in January and have no fear. Thank you for such a great product, I buy it by the gallon. I am disabled and not able to buy a new car so you are keeping my car running like a new one.
