Then your original comment is still wrong, because diesel engines are significantly more thermally efficient than 25%. Even modern gas engines tend to beat your 25% claim.
No, we’re on the same page you just haven’t read enough of it. The very article you linked says Otto engines can reach 30% efficiency. It also touches on other 4-stroke engine cycles.
Are they not four-stroke?
All Otto cycle are 4-stroke but not all 4-stroke are Otto cycle.
Such as Wankels, ok, just replace “Otto cycle” with 4-stroke in my original comment.

I guess we’re not on the same page on what a four-stroke engine is, as only one “stroke” of four is doing actual mechanical work.
