If he wants Valvoline, we tell him we use Valvoline...etc.". I was appalled. Gxx knows what they use - probably bulk stuff and who knows if the oil is the right viscosity. So, with all these problems, I think that I am going to go with Mobil Super Synthetic 0w-20 and the Fram Toughguard TG7317 with a 5000 mile OCI after I get rid of the factory fill (15% oil life as recommended). If have used this oil, or Peak Synthetic (5w-20 flavor) with this filter and OCI, in my other Hondas with the 2.4 litre engine and all of them run extremely well. I just had the valves adjusted on my '03 Accord and the mechanic said that everything looks super clean and within specs. As was mentioned, the owner's manual simply says to use any SN rated 0w-20 and both oils are that. I look forward to more feedback. Thank you!
With this modest OCI, Mobil Super Synthetic is sure an option. But consider Castrol Magnatec 0w-20 as a less-expensive alternative that's very well-regarded here or Mobil1 AFE 0w-20, which is perhaps more easily found and not much more expensive.
