Question on MOTORVAC versus BG Products flush (BK44K).... Are both about the same in removing carbon from the induction system? For 98ES300 getting ready for 90k maintenance, I looked into availability of the MOTORVAC in the eastside seattle area. No one does it in my immediate area, BUT some said they use the BG Products cleaning system to decarbonize the induction system and it works wonders. So, is it better to travel a little, through Seattle traffic, to get the MOTORVAC cleaning or is the local BG Product flush just as good?
Search has turned up people claiming the BG44K product is good and that is used as part of the BG cleaning process. Both cost about the same (~$130). But it seems that the rage is all for the MOTORVAC process.
