I recently did an oil change on my 4age 100kw small port and have just realized that i used 5W 40 instead of 15W 40. I used shell helix ultra. the oil pressure is unchanged at all operating rev ranges.

depending on how worn the engine is (eg. doesnt burn it) you'll probably find it'll rev a little smoother and 'maybe' use a wee bit less fuel.
i used to run HPR5 (5w40) in my ~90- 100,XXX + k 4agze.
