Steve Brown uses Lucas Heavy Duty Oil Stabilizer for Modified Pulling Tractor

To Whom It May Concern,

My name is Steve Brown and I own and run a modified pulling tractor with two alcohol injected big block Chevy's.

Being on alcohol I have to change the oil after about every four runs. I started using Lucas Oil Stabilizer, adding one quart at every oil change and this past year has been my best pulling year ever.

I had a problem with an oil filter plugging up and losing oil pressure two weeks in a row.

It burnt the rod bearing very badly both times and starving for oil. Neither time hurting the shaft or the rods. I rolled in new bearings and was ready for the next week of pulling.

It did take me two times of this happening to find the problem. I am HOOKED on Lucas products from now on. I add it to everything I own. Cars, tow vehicles, lawn mowers, anything with oil here has Lucas added to it.

Thanks for a great produc
