I have learned a great deal here in the past few days and have yet another question about my new Honda Ridgeline. It has an on-board computer that some other Hondas and (I think) a few GM cars use to "analyze" oil life. It measures start ups, trip durations, RPMs, temps, etc. and comes up with a percent of oil life based on your driving habits. When the message comes up on the dash that you need to "service soon" you have about 15% oil life left; at 5%, you get a "service NOW" message. These messages are suppose to be when Honda's computer feels you need to change oil.
I'm not sure I trust this thing 100% but I would like some thoughts from those who have such a system. The reason I'm not so sure about this system is that it does not know if you are using good or junk oil, synthetic, EM type or what. If you have such a warning device on your vehicle is your OCI based on the computer message or on mileage/time factors? If you have one of these on-board systems and do not use it as your guide, please tell me why? Thanks in advance.
