I've heard of BG products before. I've never really looked into their MOA line. You mentioned the slight improvement in consumption and I must ask if your driving conditions have changed at all in that time frame? Things like high RPMs and traffic seem to cause a faster rate of consumption for obvious reasons.

I'm going to ask my mechanic about the MOA, I know he's an advocate of their 44k product. I'll see if he can get me a couple cans and I'll run it. You add one can every 3000 miles?

Also, had you have had a cylinder leak down test? This could possibly isolate the source of blow by to a specific piston or oval cylinder. I sort of want to have to test done so I can confirm its the pistons and eliminate valve steam seals as a potential cause.
Your question about my driving habits is a really good one, because as you noted that will affect consumption. But no I haven't altered my driving at all. I do believe that the improvement in consumption that I am experiencing is a result of the MOA. However, as I alluded to before, I am working off of limited data at this time, and won't make any absolute conclusions until I have more complete data.

So far I have added the MOA at a 3000 mile interval. This interval works out to maintain a reasonable concentration of MOA with respect to the rate at which I am consuming oil, without exceeding BG's recommendation of MOA to oil ratio. Looking ahead, I will most likely just add a can during my regular oil change and then 1 more between my 7500 mile oil change interval...however this should all be adjusted for individual rate of consumption...

I never did get a compression test; deemed it would be inconclusive and thus not worth the expense...
