Bill Eichelberger Is A Believer

I'm a beliver. i have a 1989 ford f 150, i changed out the motor with a 1984 ho 302 with about 13,000 miles on it. this motor sat for about 25 years. I changed out the intake and must have gotten some of the wire brush down inside the block. After i put 500 miles on the motor i changed out the oil and filter and added lucas heavy duty oil stabilizer. I ran the truck for another 3000 miles, when out in the middle of no where with no cell service and 17 miles to the nearest town ( jordan valley oregon) my oil pump freezes up. It picked up some of the steel from the wire brush. I had no choise but to drive the 17 miles to the next town. I said a little prayer and took off. long story short i  made it there called a friend to pick me up and tow my truck back to bosie idaho.

I pulled the oil pan and sure enough the oil pump drive shaft was twisted a full turn and was snaped in half an inch from where it plugs into the oil pump. I changed out the pump and shaft, looked at the rod and main berings, and put it all back together. It fired right up no knocking or any other noise. I still cant belive it. When i stoped at jordan valley my truck was making death rattle sounds, now you would never know the abuise i put that motor through. I will use Lucas Products in all of my engines, lawn mower, weed eater, whatever, i have told everone i know what a supierior product lucas puts out. I am a coustomer forever.

Thank you Lucas Oil
