Again, perhaps this is worth a look CENPECO

I buy it from a local distributor who delivers it to my shop for about what any good average qt of oil goes for. Have a few engines with it in them but nothing pulled down yet. I will say it has a cling to it like no other I have used, even hot with miles on it.

Said it before, VR1 in my 408 with pretty quick ramp solid FT since it's start a few years ago but only time will tell how good it is.
