Thanks Frenchtown, I never heard of that idea of mixing to make the blend. My I4 takes 5 quarts so 1 synthetic for the protective properties and 4 regular for my wallet, would work out good since I like to change it often. I would never leave all the synthetic stuff in there the way some people go 15,000 miles with no change. I just don't trust it that long for how dirty I get everything wheeling. I also saw they have a synthetic blend made by I think Quaker State special for you type of vehicle, like I would use the 4x4 one. I dunno how much more a qt that stuff is over regular dino juice, but it is no where near the price of a case of Synth. I like the idea of making my own blend. cool, thanks.
