I am on my first oil change after finishing my full ARX treatment. I put in GC (the green stuff). The car is at 4500+ miles and it's almost a quart down. So either ARX helped or the GC is helping, or both. But, unlike what I would have done in the past, I'm simply going to add a quart at the 5000 mile mark or so, and drive another 3000+ miles. Highest OCI on this car ever.
BTW, it's a 93 chevy caprice, 350 TBI, 214k.
