I dont know why you would want to do that. The multi viscosity and straight weight oils wont mix and the multi viscosity oil will be expended faster when it is at its low end. If they happen to reach the correct temperature together, they will flow as united and become the same weight but never be homogenous.
Nothing if they were approved oils. You can mix 10w30 with 5w20 etc. Not a good idea but you can do it. You can mix brands with no problem.
why would you want to? Yes you could, the viscosity will average out .
when in doubt it's always 50 to one. one pint of two stroke oil to 6 gallons of gas. Actually, I have one of these motors and the manual. The mix is 50 to 1, 1 imperial pint to 5 imperial gallons or 1 US pint to 5 US gallons according to the manual. Use SAE30 or 2 Stroke oil, not 10W30.
That's okay.
usually motor oil and a sugar mix
Any name brand 10w30 would be fine. Don't mix synthetic and non-synthetic oils.
No. There is a oil tank much like your car that you top off.
The intake manifold in a motor is like the lungs of your car. Air is taken in through the intake manifold and then is evenly distributed to the cylinders to mix with gas.
No worries. If 10w30 was suited for your current climate then your new mixture will do just fine. If you needed to use 5w30 because the temps are still below zero in your area, then you may want to change to entirely 5w30. I remember hearing about people with LS1's in their Camaros mixing 4 qts of Mobil 1 10w30 and 2 qts of 15w50 in order to achieve a mix that was similar to a 10w40.
No problem at all.Tip: Always use Fully Synthetic engine oil in your car/motorcycle.
Yes, as long as the ambient temperature is above fifty degrees.
Yes
