So I only have 2k miles on my new Honda Pilot. The owners manual specifically says in 2 different places not to drain the factory fill early. The Oil monitor is at about 80%. We are getting into the winter months of Chicago. This car is usually garage kept over night but sometimes sits outside as my wife works 3rd shift. Should I drain factory fill early and replace with the Redline 0W20 I have or should I follow the owners manual? IF keep the factory fill,should I replace the filter at 50% and add 1/2qt of PP to top off? thanks for your replies.
