Chris,
-MMO is not a BG product-Do you change the oil w/in a week of adding the seafoam,? (otehrwise the varnish may re-deposit as the seafoam concentration in your oils goes down).-Some members have had the most success with ATF, use MOBIL1 ATF, in a Q you can put in a full quart, and let it idle (or drive <very> gently) for at least 30 bettter 40 minutes <right before your oil change>If done right before oil change and just idling/or gentle revs it is perfectly safe, I have done it at nearly every oil change in the last couple of cars I owned.-yes a heavier oil will cushion better and many have found lifter noise reduced that way , it's certainly worth a try, with summer coming a 10w-40 is a good choice anyway.-The DuraBlend is a good oil especially in 10w-40 where it meets ACEA specs (one of just a feew non syns to do so)
I gotto run, am late for something.
