<![CDATA[BYD Shark 6 & Sealion 6 DM-i First 1.5L/1.5T Engine Oil & Filter Change DIY Notes (0W-20 API SP)]]>For BYD Shark 6 DMO and Sealion 6 / Seal U DM-i owners curious about the hybrid engine maintenance schedule:

On-Road Impressions, Efficiency & Setup Details

  • Oil Spec: Fully synthetic 0W-20 API SP / ILSAC GF-6A low-viscosity hybrid engine oil (3.8–4.2 litres with filter).
  • Because DM-i and DMO engines run mostly in their optimal thermal sweet spot (1,600–2,400 rpm steady load) and have electric water/oil pumps, the oil comes out remarkably clean—though doing an early run-in oil & filter change after the first 5,000 km of HEV running is great preventative care!

Being able to run a 2,000W induction stove and espresso maker off the V2L socket while only dropping 3% SOC over an afternoon is a game changer.

I checked the service manual torque specs and fuse layout over the weekend and everything matches what you outlined here.

Every EV and PHEV platform has trade-offs, and seeing real long-term feedback like this is why independent owner forums are way more useful than brochure numbers.
