Guys,
If I am correct, ever since Honda started using the OLM back in 2006 they went to a 1 year/or go by the monitor which goes alerts you at 15% oil life left, down to 0% in 5% increments, which ever occurs first.
Factors such as short trips (low oil temperatures), operating outside peak efficiency such as very low rpms or very high rpms, or high oil temperature are factored into rate of decline of the OLM output.
I know that although slightly, the PP will keep the engine cleaner for the long haul. I just wanted opinions as to whether YB might give slightly better wear figures or mileage considering how easy this engine is on oil and the light loads it sees with my mom driving it (top speed in 7 months for her 50- for me 75 on city streets).
I don't think the long year drain is too much for the YB or I would think the OLM would reflect that and direct you to change it sooner.
I guess if there are no negatives to using PP 5w-20 at all, then I'll spring for it and have some piece of mind.
Not to change the subject I decided against including Mobil1 5w-20 (EP) not because I don't think it is a quality oil, but from my experiences with it seems to cause slightly noisier engines, which I do not want for her. If PP turns out to be noisier than YB I will switch back to it.
Thanks for all the replies,
Gary
