My wife's 2020 CRV EX-L, which is a proven dilluter because of almost exclusively being short-tripped and only driven about 3k/yr has been using Mobil1 5W-30 EP without any issues and with the dealers blessing. I find it easier not to obsess over it. Goes in for an OCI every 6 months. My Civic Touring Sedan is running Mobil1 0w20 EP as it's showing low OD, changing every 4-5k, will probably go to 5k next change. CRV,s seem to have more OD, ours because it seldom gets a good highway run. Everyone has different driving patterns but Honda's1.5t definitely works best when driven enough to get the oil hot enough to evaporate the fuel.
