Yes - the car boys run their racing engines on very low levels of oil, scary low sometimes.

Don't know if you've been to many car races, but they're fun to watch and they run the poo out of their engines and cars. They tune by sound and temperature - all the competitive drivers have a screwdriver sticking out of one pocket and a digital thermometer in the other. They are really pretty good engine tweakers and since the tracks are not large, they can easily see and hear how their cars are performing. Race preps are usually run a lap, drive onto the pit ramp, check the temp, tweak, then run another.

Having a box of $350 engines at a race is not too unusual. Frankly, when they're running in the mid-twenties enclosed in a car body, on dirt and with such low oil, I don't know how they last.

BTW, my numbers matched LG's, assuming the lube was initially 100% syn. To come up with the exact numbers, we would need to know Trinity's syn/cas ratio.
