I purchased a 2007 Honda Pilot earlier this week for the wife. It will be her daily driver, about 30 miles a day mostly highway. The car was sold as "certified" by Honda which included several fluid exchanges - ATF, brake, coolant, oil, power steering, etc. I checked all the fluids before purchasing and feel comfortable that all were changed except the p/s fluid, which I have already changed. I am fairly certain they used Pennzoil conventional as the oil fill as that is what they advertise in their oil change shop, and I know by inspection the oil filter is an OEM Honda by Filtech (supposedly the better filter). My question is how long to run this fill since I don't really know what it is. I know color doesn't matter but the oil on the dipstick is darker than I would expect for a recent oil change. I have some Synpower ready to go, but don't want to waste the oil fill if its OK. Any thoughts?
