From my experience it will take about three fill ups to get the proper dilution throughout both tanks. I normally add 15 ccs of Archoil at each fill up and over time that creates and maintains the correct dilution (or a bit more) throughout the system. Today was a good example. We drove from Spokane, WA, to just over the Columbia river on the Oregon side. It was between 98 and 102 the whole way. I don't think the fan clutch is functioning properly (will replace it before the next trip) and the temp gauge in the Clasco seems to read a bit high. We were 205 to as high as 220 indicated with lots of long uphill grades. The only blurble was after a stop for a drink in Kennewick, WA, during which I left the engine idling to keep the AC on for Sharon. When we started back up we had a long, tough uphill pull over the Horse Heaven hills on the way to the Columbia river. I felt a bit of vapor lock, turned on the aux pump and normal drive was re established without slowing down
. Off with the aux pump after about a mile. End of issue. Hope this works as well for others. I do need to restate that I now only use fuel from Costco, Chevron or Shell. I know many say all the fuel comes from the same source with only a can or two of additive added to differentiate one brand from another, but that has not been my experience.

I purchased the Archoil based on these and other recommendations. Will test on tomorrow's trip going East. It is amazing to me that such a small
quantity of additive can make a difference. I am sure the chemists on board can explain...
