My 2002 Envoy (199890 miles) was beginning to use oil the last year or two. About one quart every 2500 miles. I ran the BG EPR for about 20 minutes at 1500 RPM as per their instructions before the last oil change. Changed oil and filter as usual.
So far, as of today I have 1000 miles on the oil change and it hasn't moved from the exact "full" mark that I filled it to during that last oil change. I know it's too early to tell for sure but it seems to be helping.
The only other change I made was to go back to the 5/30 W Valvoline Synthetic Blend that I used for many years before switching to the Mobil One Extended 5/30 W. I know this throws a variable into the equation so nothing is perfect with my hypothesis.
Will keep you all posted as the miles increase.
