Kathy Porter uses Lucas Heavy Duty Oil Stabilizer

We use Lucas Heavy Duty Oil Stabilizer in our dragster as an assembly lube and also as an additive to our regular engine oil. On more than one occasion it has saved us from replacing our rotating assembly. I went an entire pass without oil pressure and upon teardown we found that the Lucas had saved our crank and rods. I tell everyone I know to use this in their racing engines for extra protection and they will be glad they did!

On another note, just yesterday I lost the oil pressure in our old Ford pickup on the way back from Denver. This engine has well over 200,000 miles on it and is pretty weak. We put new oil in the crankcase along with 1/2 gal of Lucas oil stabilizer and drove it home from the truck stop. Thank you for a great product.
