Fits my Accord
Simple easy install for my 2016 Accord. No changes in sound, no changes in how my vehicle runs. Nice it’s 18k miles.

Great oil
Size: 1 Quart, Style: 6-Pack, Configuration: Euro 5W-40
OEM for many European cars. Have utilized for years in my 2 Fiat Abarth's, great oil at a competitive price and if you change oil yourself you save quite a bit as compared to dealers or other shops. No breakdown even with the excessive heat the little 1.4L turbo puts out, great oil to rely on.
