The high mileage oil supposedly has some additives that make the gaskets swell so it reduces leakage/seepage. I would not use it in a brand new car. Even my 2005 Camry with 160K Miles doesn’t need it-yet.
Honda usually wants to keep the factory fill in for longer because of the high Molybdenum content, so be aware of that. Don’t change the oil at 1500 K miles as was done in the old days.
I just bought two 5 qt jugs of Mobil 1 from Walmart and submitted the online rebate for $12 each, it is going on until the end of October. WM is not on their list of retailers but on previous tries they have issued me the rebate check.
Most of my cars now need 5.5 qts-I guess because they are direct injection, these are still 4 cylinder. But that 0.5 has turned into a PITA. I have an extra gallon in the garage to top off at every oil change to make it 5.5 qts.
