I have a 2005 Tacoma and do not drive it more than 1k/yr.  So, I go multiple years on each M1 0w20 oil change.  (Yeah, the oil cap says 5w30, but 0w20 wasn't made then.  I just use 0w20 in all 3 vehicles.)  Oil never looks dirty.
Had a VW TDI for nearly 7 years.  Went 10k on oil changes on it and also on our Mazda3 since 2016.  However, we're not putting enough miles on either the 3 nor the Miata now.  So, I'm going multiple years on their M1 0w20 oil changes.  Strangly enough, the Miata and the Tacoma 2.7 L take the same oil filter.
Synthetic can go 15-20k miles and multiple years.
