I Use Lucas Stabilizer in ALL of My Vehicles!
From the Daily Drivers,to my Race cars.
I Buy it buy the Gallon,and in My Daily Drivers,I add about 1/2 Quart at every other Oil & Filter Change.It Just Puts some SLIPPERRY back in the Worn Parts along with No so Worn Stuff!
Next Oil&Filter Change,dump 1/2 off the Quart in.The Old 4.3 will Tell You Thanks!!!
