Kenny Gilmour uses Lucas 20/50 Plus Racing Oil in NHRA Top Alcohol Dragster

We have been using various brands of racing oil for the last few years. We have observed a multitude of scrubbed bearings due to alcohol dilution, further the stay in grade qualities proved weak. In July 2004 at Mission raceway we did not pack enough of our sponsored P brand of oil and decided to buy some 70 wt Lucas. We are happy to report the life of our main and rod bearings has made a dramatic improvement. It appears the Lucas 70 Wt can support higher loads, has a greater film strength and superior heat rejection characteristics compared to other brands we have used in the past. Bravo Best regards
