Woody Cofield uses Lucas Heavy Duty Oil Stabilizer for 1986 Jeep Pick-Up

I wrote ya'll not long ago and told ya how impressed I was with the Lucas Oil Treatment.

Well, my 1986 Jeep Pick-up 2.8 V6 4X4 started making grinding noises from underneath in the transfer case.

I remembered how well Lucas worked on improving my mileage and how it can be used in the trans,& transfer case & differentials, so I added it to all. The transfer case was down a full quart and the rest took another quart.

I was thinking of selling my Jeep, but now it runs so smooth and no more noise.

Thankx for a truly remarkable product.

Sincerely,

Woody Cofield
