Tom Bayer Racing Has Used Lucas Oil Products Since 1996.

In my 1040 horsepower Super Comp dragster I use the 20/50 racing oil, after 150 laps we pull down the motor and inspect everything. Not once have we found any oil related problems, the main and rod bearings always look great. This super comp dragster goes from 0-to 60 in 1.6 seconds in an eight mile @ 136 mph, and 7.50 seconds @ 178 mph in a quarter mile, this rocket-ship travels 240 feet per second. We depend on the 15/40 and the oil stabilizer to keep are 98 Frieghtliner motor home, on the road, which we average around 20,000, miles a year, traveling race to race. We also have found that my wife's Toyota Camry has picked up 2 miles per gallon using the fuel treatment. Lucas Oil Products really do work.
