You can do an early UOA. You do not have to drain the oil to check it now to be safe.When I hit 7500. It will be a while.
The increased fe is the same and occasionally better than D2. Straight D2 I avg. 33mpg. Last few tanks I'm at 34 with B20. I should probably not make it sound like such a big increase but when the car is used by me I get a better tank than my wife, who drives like an old lady. The car is probably getting better fe as the motor breaks in...I'm guessing.
Interesting, the same commute with my 05 Passat got me 30mpg, at most, on B20.
Dip stick does not show an increase in volume....yet. But I will keep an eye on it as usual.
Just ordered the Blackstone Kit.
Just saying it is better to know now than wait and find out the hard way...Kind of like the Dr., the longer you wait the worse the prognosis.
Again, remember I want to be proven wrong, but my research convinced me that Post Combustion injections on the CRD do not work with even B20.
