Recently purchased my first E, a 2008 EX. When I got it the oil life display showed 60%. I have a couple of questions. Firstly, should I trust this and run the car until the oil life gets low (in which case how low should it go before I change it)? Secondly, I've normally gone to Valvoline to get my oil changed since there's one right by my house. I know they have a special oil for high mileage cars (mine has 83k). Would this be appropriate for my vehicle, or would i be better off taking it to my local Honda dealership. Just wondering if there's anything from the dealership that makes it a more attractive option.
