However, I hardly drive it, so I hadn't changed the oil for a while. What should I put in next? I was thinking of using Wako's additive or Prostage 10W-40, but... I happened to come across a video showing the use of mineral oil in an EK9. Since I used to own an EK9, I took a look, and it was presented with scientific evidence! I was drawn into the discussion.    • 【VTEC死んだ？】Civic Type-R EK9 / Integra DC2　合...      • 【油温120℃でも大丈夫？】Civic Type-R EK9 / Integra D...   [The Danger of Polymer Degradation] Civic Type-R EK9 / Integra DC2 ── The Dark Side of Polymer Additives | The "Design Philosophy" that Protects the B-Type Engine...    • 【ポリマー崩壊の危険】 Civic Type-R EK9 / Integra DC2...   @YouTube I watched this trilogy and it looks interesting! I also watched various other videos and think this might be very good for older vehicles. With that in mind, I decided to try Rise Oil's GT-RS, specifically the thicker 20W-50 mineral oil, in my Civic this time. Also, I haven't really filmed many maintenance videos before, so I tried filming one... I wonder if there's any demand for it... Please enjoy this video of me changing the oil while rambling on. If the view count is good, I might post a progress report video. This video is not sponsored or anything like that; it's just a hobby.
