Out of being curious, I went to the Cactus site and found the listings for oils. CAM-175 BeNOL Racing Castor Oil. $5.50 per pint. CAM-200 Techniplate Racing Oil. $7.70 per quart. By the way my loggon name KLOTZ means nothing towards an oil preference. I have all kinds of engines, all kinds of oil. Which of the oils listed with "Cactus" will, make all my motors, run cooler, run cleaner, develope more power, reduce tear down time, reduce engine wear, reduce bearing failures and leave my cylinder and piston slightly stained next time I tear these abused motors down for inspection of course! After all this I gotta try this stuff. Who carries this other than Cactus. I might have a preference here?
