Ok i dont like to promote stuff but I did a compression test noticed cylinder 3&6 were a little low. The next day i was telling a shop owner friend of mine about it and he gave me a can of BG 109 and a 5qrt thing of mobile1 for FREE! He told me to do a oil change then run the 109 through and do another oil change with my favorite oil. So i did the oil change, I checked the oil level, oil was clean and clear then I ran the 109 like it said too. When i was just about done I started smelling something burning and their was a little thicker smoke from the tail pipe. Anyway finished up and drained the brand NEW oil and it looked like i hadn't changed it for 10,000 miles it was so black. I got everything done and did the compression test again all cylinders were GREAT!!

I've found some videos on you tube about their MOA stuff and really want to try it but my friend has to charge me for it so next pay check maybe.

Anyway BG check it out

 

Sounds like a seafoam treatment of sorts. How'd you "run the 109 through"?

 

Much like most treatments I guess add it to crankcase bring the engine to normal operating temp then increase RPMs to 1200 for 10 min
