Hi Everyone,
Got a report back from my very first UOA. Had heard of Blackstone services a long time ago and now finally have a reason to use them.
Obviously the crankcase dilution is concerning but after doing a lot of reading on this forum and elsewhere on the internet it appears a long drive using the ICE continuously and holding the engine temperature at a it's peak operating temperature for a sustained period before draining and sampling the oil may alleviate the fuel value. On this oil change I made a 16 minute 8.5 km drive to my father-in-law's place to perform the service.
Prior to this oil change I drained the factory oil at 1,788 kms (1,111 mi).
My plan is take the M1 AFE in the crankcase now to about 14,000 km (8,700 mi) and test again to see how realistic the Toyota-recommended interval of 16,000 km (10,000 mi) is for my usage. Had someone at siennachat.com respond that OCI would be "pushing it" as a new engine has loose oil control rings that can be jammed up with dirty oil. I prefer to make OCI decisions moving forward with UOAs. I feel like there is a large segment of automotive enthusiasts out there who cannot shake the old change-dino-oil-every-3,000 mi-or-4-months mentality.
My use is primarily urban with only 10% highway. I have tried to squeeze the most fuel economy out of the vehicle by using the ICE as little as possible (coasting, very light and gradual throttle application). Since getting the van last summer I have averaged 32 mpg, with a high of 39 mpg in the summer and lows of 25 mpg in the winter (ICE runs more when outside ambient temperature is low). Pretty good for an 8 person family hauler that can also transport 8' fence posts and box springs! We're super happy with the purchase.
