I have been using the Lucas Oil Stabilizer in my engine oil and it doesn't froth like that. Wouldn't the frothing be apparent on the crankcase dipstick? Perhaps his experiment is flawed with possible air compression through the gear teeth?
My oil consumption is down with the additive in the oil but I am not quite sure of the quantity since the dipstick obviously doesn't have any capacity markings. Also the car is rarely parked on level ground overnight so I don't think I am getting accurate readings. I'll have to set up more scientific tests.
