Well…I can report a marginal improvement on the Audi Q5. I’ve gone from burning a quart of oil every 200-250 miles to burning the first quart at just over 600 miles. I suspect the treatment “unstuck” the rings one cylinder and not the others. Since this is a fairly straight forward process, I will do it again at 3,000 miles and report back the results.
