Twin F150 Left uses more oil

[exttrimmer]

Hi Guys
I have a pair of 2005 F150s counter rotating. I use engines to ***** on Lake Ontario. Total of 750 hrs on both engines. I usually perform my own oil and filter changes. I follow maintenance schedule religiously. I have noticed while doing last two oil changes that one engine burns about a quart more than the other. Is this a big concern. I check oil regularly and it doesn't seem to be any lower over oil change interval. Really noticeably when I use oil sucker.
Is there anything that I should be doing to stop this from happening. Is this an issue that I should have a tech look at for me.
Concerned but not desperate yet. Looking forward to suggestions
Thanks

Engine oil never has to be added = no issue in my book.

When you change the oil level should be about half way on the stick, not at the full mark.

If anything the F150 tends to "make" oil. I would guess that the engine burning less oil might have an issue with running a bit cool.
