If I need to add a little oil to the engine, and it was filled with 10W40 synthetic, and I only have 5W30 synthetic right now - will that work? Is it safe? I need to put in an extra quart or a bit less.

It really won't make a difference, honestly...
The oil is read in thickness (i.e. 10w-40). The oil acts as a 10 weight oil in the Winter (hence the W), and a 40 weight oil in the summer. Adding a different oil will just blend it a little.
Plus, it is better to have any kind motor oil in it than none at all!
If you're running an older car that used to run on conventional oil, now synthetic...there is the reason why your losing oil...synthetic oil will find its way out of any older engine and show you where all the leaks are located!!!

I don't think it would matter, just make sure that the 2-stroke oil is the same concentration, I saw 2-stoke oil on sale at West Marine, I looked at the "50:1" fuel ratio and it was something like 3.5 oz. of oil to every gallon of gas, as where the other major oil brands are 2.8-3.0 oz. of 2-stroke oil to every gallon of gas (It's cheaper but, you must use more of the WEST MARINE oil). I have a 2005 Johnson 50 h.p, I paid EXTRA to have the "VRO" removed, and add the oil manually to the fuel (It's only a 7 gallon tank, so it's no biggie for me, a larger motor would require a lot more mixing of fuel)

No difference except that 20w-50 stays thicker (thicker more slippery) longer but is not great for winter start ups. If you mix them the engine will mix the different oils into an average consistency. 20w-50 is best for older cars. The change-your-oil-every-3000-miles sales pitch is a big lie. The governemt started the business to stop people from dumping used oil in their back yard. Once the industry got going, the corporate lies started to boost profits. Keep your oil above half full at all times and change your oil filter and oil once a year. 5w-30 is good to have around becuase you wouldn't normally use it, except when you don't have anything else - then it's great. 5w-30 is designed to provide the least protection to help engines wear faster to increase auto sales.

No problem. It will mix fine, and will act as maybe an 8-38, depending on how much you put in.

Yes, that's fine.
