One 20 Oz bottle is the capacity.
I'd say $50,000$
1/2 quart
190cc equals how much horse power?
Yo mama fool...
possibly a lot of carbon build up in the combustion chamber but in a lifetime I have never had a small engine with to much compression.
If you are referring to a riding lawn mower, the manual specifies 12 - 14 psi in each tire.
Since you don't specify, I will assume you mean a power mower. A stripped-to-the-bones walk-behind power mower? $140 - $180. A bells-and-whistles self-propelled walk behind? $350 - $400. A lawn tractor? $1,000 and up.
If you want a push mower with good power find and older one with a 3.5 or 4hp Briggs and Stratton. Or an old Lawn0Boy 2-cycle

A 17.5 horsepower Murray riding lawnmower should always have 1.5 quarts of oil in it. You may have to add more than that after an oil change because some of the oil will go down into the oil filter.
You should always have 20 fluid ounces of oil in a Briggs and Stratton 5.5 HP lawn mower. This equals out to roughly 1.6 quarts.
I'm not sure I understand your ineptly phrased question, but if you want to know how to safely walk behind a horse, here is the answer: When you walk behind a horse you first of all want to make sure the horse knows you are there. So approach the horse from the side, touch him on the neck or shoulder so he knows you are around. Then when you are behind the horse you either want to be within about a foot of him (so if he kicks it won't have much impact), or you want to be at least 4 feet behind him (so if he kicks he will be too far away to make contact with you).
