There was quite a bit of backlash against Blackstone on nasioc when an Amsoil dealer was bad mouthing them there. The new DIT WRX's are having
very high fuel dilution and Blackstone's method for fuel dilution extrapolates the fuel reading based on the flashpoint and they do not actually test the oil for fuel. The Amsoil guy got a little out of hand and the President of Blackstone started posting.
My problem with them is that they will see a WRX uoa with apparent high fuel dilution, the viscosity is a 20 grade from contamination and/or shearing, and they will advise someone to go an additional 2,000 miles on that oil because the "uoa wear numbers are normal", even if it is beyond the interval that Subaru recomends. This article warns against reading too much into one or two random uoa's and using uoa's to compare oil in general.

Having said that, the twins
do seem to tolerate well on most oils in street conditions. Thank God you guys have the Toyota DI system!
