I've tried to make a science project out of two vehicles. I did "before" compression checks and UOA. It will be Spring most likely before any "after" testing is performed.

One vehicle had never been ARX'd. The other vehicle had been ARX'd twice, which brought it's oil consumption down from one quart every 1,700~miles to a quart every 3,000~ miles.

Checking 1,000 miles into the Cermax treated oil change interval the dipstick was still on full.
