Share on social networks:
Use a brand name, high quality oil, Pennzoil, Mobil 1 Castrol, etc. always change your oil filter and crush washer too, using OEM Hyundai filters or WIX! Mahle and Denso oil filters are also acceptable.
Pros: Denso oil filters
Vehicle:
Hyundai
I like the Denso filters from RockAuto.
Pros: good quality
I will always use nothing else except the denso made OEM filter. The flow rate, the drain back, or lack of one, is perfect for this engine.
Pros: perfect flow rate, good drain back

I buy Wix or Denso on RockAuto

I’ve been using Mobil 1 ESP and Denso filters since replacing the engine. Will let you know how it holds up in ~100k.
Mileage: 100000 km
I run densos on all my vehicles, including my built turbo charged Tacoma. No problems.
Pros: No problems
