I have heard people talk about mixing some high milage and regular dino to allow for some seal swelling but not too much...
I gues that alternating regular and high milage OCIs would do about the same thing.
If you go with the mixing, maybe 40% High Milage and 60% regular dino???
I use 2 quarts Havoline Synthetic and 3 quarts Havoline dino. I get a good syn blend with 40% syn...
