saand, if you're lucky, you might find a BSFC graph for your engine on the internet. Otherwise, you'll have to do like I did, and experiment. Most 2 liter engines get best BSFC between about 1500 and 2200 rpm, at about 85% load, but YMMV. My SE-R and xB both like 85% load, but 85% on the xB is slow-moderate acceleration. 85% on the SE-R is brisk acceleration. I tested P&G on both my cars in different gears, different speeds, and different loads on the same 10 mile loop to learn what worked best.
