OP here, thanks for the input and usual MMO debate..
I ended up heading out without any additives in the crankcase or gas tank. I bought the van with 150k miles, one owner but no records. I do believe it was maintained regularly due to the overall condition of the vehicle, and good UOA's.
That said, I'd like to pull the front valve cover and if there is any varnish or cleanup needed. If so I'll do an MMO treatment with progression photos. I have plenty of oil and filters to use in the trial. (In signature)
I thought I might try MMO in the crankcase on the trip home to perform some cleaning before draining, but without before/after photos, it's anyone's guess what the MMO did. I'd like to use the opportunity (of a dirty engine) to document what some of these additives do.
Here we are at the rental neighborhood :
Illinois iPass next to the Florida Sunpass sticker. Despite them telling you it needs to be STUCK to the windshield to function, mine is taped there and it worked fine.
We got 20mpg to Effingham, IL. 23mpg Effingham to Murfreesboro, TN. 24mpg from Murfreesboro to Macon, GA. (Haven't filled up to calculate the final MPG.) Seems like the fuel got better as we headed south. Perhaps no winter blend down here?
