Bought a 2005 Accord 2.4l, Gen 7 & K24… I think. Ran it for a couple hundred thousands miles…then bought a 2016 Accord, now have 65K on that. Here in Michigan with road salt other things get you before engine miles.
Anyways I used 0W-20 on both…however, agree with comments on this forum that 5W-30 would be fine. On my 2016 which is GDI, I do plan on switching over to 5W-30 when my 0W-20 stash runs out. I do 6 - 7.5K miles on an oil change with whatever synthetic is on sale…or better yet, clearance!
