I bought my ole 83 F150 a couple of months ago. I knew it had over 285,000 mile and I knew there would be leaks and such. Since I got such a deal on the truck I desided to make it a LUCAS truck. I have used nothing but LUCAS additives to my truck. The motor, tranny, power steering, rear axle, fuel, you name it. To say I am happy with your product is a vast understatement. Its like driving a new truck. I done this as an experiment to see if the your product could really bring back this ole truck back to life. IT DID! What is the most shocking thing is the money I have saved. Not in just repair bills, but in fuel economy as well. I tell everyone I see about your products. All I have to do is start my truck and pull it up a few feet and tell them to look where it was parked and show the results of no drips, or stains on my driveway. Then I watch their jaw drop. I wish I had the money back I have spent on other products that didnt work on my other trucks. I'll never regret making this truck a LUCAS truck. Keep up the GREAT work.
