Nathan Casler uses Lucas Synthetic Oil Stabilizer in 1986 Ford Ranger

I've been using you oil products for about 1 yr and after the first use I noticed a 4 mpg gain.now I am also using your tune-up-in a bottle and your transmission stop slip. both have worked wonders now I have no slip at all in overdrive when I apply power at over 65mph. the price is high but every bit worh it in the end. thanks, Nathan
