2011 Hyundai Sonata Hybrid @90000 mi
Out: Valvoline High Mileage Full Syn 5w-20; OEM 35505 filter
In: Valvoline EP Full Syn 5w-30; OEM 35505 Filter
OCI: 3200 mi
Fumoto valve makes me wonder if I can change oil w/o an oil pan. It all works well until I'm ready to take the filter off. Filter doesn't care, oil dripping left and right, eventually I have to grab an oil pan to finish the job. Almost forget to collect an used oil sample.
I'm surprise the oil getting that dark, it only stay in my car for two month and I drive on highway most of the time.
Valvoline EP doesn't quiet my fuel rail( or valve train/injector, whatever the noise is), next time will definitely give QS a shot. In fact I can't feel any difference compare to 5w-20 on the way to recycle oil.
BTW some part of my car's under-body has similar rust shown in pic2. Should I be concerned about it and apply some WD40 as protection, or leave it alone? Currently I'm following my user manual, give her a bath with undercarriage wash every two weeks.
