Dipstick shows no oil, can I top with 10w30 for a short drive to mechanic?

So I guess I have one of those notorious 2010 Prius that burns oil like mad.
I checked my oil this morning and although there's some oil in the system (as evidenced by oil along the side of the dipstick), the dipstick itself isn't registering a line of oil - so it's scary low. Dipstick middle is dry to touch, so not a matter of not seeing the oil. Oil check was done on level ground, cold. No oil spots ever in driveway. No visible oil leaks or even wetness anywhere under or on top of the engine.

I'm up on a mountain, no neighbors. I have access to 10W30 (used for a different car). Can I use it just to get my car to a mechanic? Or will it cause more damage? Maybe that's a stupid question, but I'd rather ask you guys than try to figure it out on my own and even then possibly miss something important. I have been running synthetic via dealer oil changes every 5-10k (now I know better, but up until today I thought that was the responsible thing to do).

Thoughts? What would you do? Looking for basic info because I know crap about cars.
Thanks everyone!

Phew, thanks you guys! I tried to send the "YOU GUYS ROCK!!" email prior, but it failed to send! I added the available oil, then added the 0w from down the hill, and then got my oil changed at the dealer. (A decision based on necessity at this point, but I checked it before I drove it and it was in between the two dimples - cold check too so I think all is good). Engine sounds fine, no knocking, no ticking. I did have to add 2.5 quarts though. I think I'll be trading her in and then letting someone else get the benefit of the certified warranty I will be monitoring my oil usage carefully until then. THANK YOU SOOOO MUCH!

 

yeah? 2016? I was thinking 2012 or so with about 60k on it... BUT for the very first time I can see the VERY real advantage of having a brand new car and being there to ensure it was taken care of as it should be.
