well, here are my experiences thus far(in a 92 ranger 2.3/5 speed):
total TC-W3 oil used: 140mL(4.7oz), so i've used it with roughly 23.5 gallons of fuel. according to the original sources, this MAY not be enough to see all of the benefits yet(since they recommended 2 full tanks, i think, and the average F-body/corvette has somewhere around a 16-18 gallon tank IIRC).
what i've seen so far:
fuel consumption: no idea. this truck never gets put through the same route/conditions twice, so my difference in fuel economy is never going to be able to be measured.
idle stability: seems to be better after using TC-W3... then again, got even better after changing out some really nasty oil in the crankcase for some proper 5W-30, so, likely a small effect.
was there anything else that was being targeted for review?
i can also be certain that this truck now requires less throttle to maintain a given speed... i can't feel it in my foot, but due to this trucks exhaust having fallen off immediately ahead of the cat, there is a noticable difference in volume when maintaining 55MPH, for example...
so, it's certainly doing something... from the way it feels, it's something good. i really need to try this out on one of my vehicles that i can grab data from... see if it's messing with fuel trims, knock sensitivity, etc...
