A friend of mine owns a 2017 with 31K miles. She brings it to me for service 9-10k miles (she follows the OLM) and the oil level has never risen. However, I did post an UOA on this site where the fuel dilution tested >5%.
We are not receiving the service campaign in CA, at least not for now. However, the software is available countrywide thru the Honda J2534 program. Since I own a J2534 tool, I went ahead and performed the ECM and CVT module updates (along with the required post-programming relearns) myself. At the time of the updates, I also performed an oil-only replacement as specified by the bulletin.
It has been about 700 miles since the update was performed. The car was here yesterday and I was able to get some time with it. Here are some informal observations:
1) The engine oil has no obvious fuel smell and the oil level is exactly where I left it before. However, I have never seen the oil level rise on this particular CRV, even after a 9500 mile oil drain.
2) The Oil Life Monitor (OLM) is down to 90% after 700 moles. This vehicle usually comes in for service at about 9-9.5K with 10% remaining, so I think the OLM is dropping a little bit faster than before.
3) I did not pay attention to the temp gauge until people start complaining about the slow warm-up times, but I did two informal tests after the update to see how long it would take before the coolant temp gauge read normally:
A) ambient temp - 45F. 3 miles and 5 min of constant 45-50 mph cruising.
B) ambient temp - 39F. 1.5 mi and 9 min of stop and go driving with stop lights. Average speed was probably 10-15 mph.
Not sure how this compares to other CR-Vs that have not received the update, but the warm up time seems normal to me.
