Blowby before+after treating with CRC and Seafoam.

I seem to have found a fix for my Equinox burning so much oil.  I did a video showing the blow-by before and after treating with CRC GDI Intake Valve cleaner and Seafoam. I added a can of seafoam to less that 1/4 tank of gas - thats twice the recomended mixture. When I was done with both things there was black suit on the pavement near the exhaust pipe. Blowby was reduced dramatically. Before the paper would float an inch above the oil fill opening after treating the paper covered it with no problem.

 

I had been using cat cleaners with every fill up for years!  Sometimes it would work but it was perhaps counterproductive.  With all the blowby the catcleaner would get into the oil and thin it out.  Then more oil would get burnt and dumped into the catalytic converter.  So I fianlly found a way to treat the problem at the source. 

I think the CRC cleaner might get to the rings as well.  However there was some brown foam coming out of the port where I was spraying the Seafoam into.


 Here is before and after readings on the lower O2 sensor. 



The O2 sensor did go back to spikeing after driving for a while but the check engine light is still off.
