Reason I ask is I forgot to tell the service attendant to use my oil laying on the passenger seat so they installed Havoline 0W-20 Syn and some UI brand of filter in the Accord. Can't fault them since I failed to tell them to use my oil and filter. I've been using PP or PU and Ultra filters in the Accord and wanted to continue with that. The MM was at 10% with 20K on the oil. Should I go with the MM until it tells me it time again, or dump it at 5K and put the Penn in? I'm just not familiar with Havoline products.
