Klotz R50 oil question?

my buddy gave me a whole bottle of maxima, he knows thats what i run, he didnt want to use it in his ktm bike because it said 'for injection" on the bottle, but in fine print it also said "can be mixed', some say for injection and some dont, might be formulated a little thinner, but the same lubrication for injection????
 
i use r50 in my blaster but i premix and when it hot is super thin like water i dont know if it has the viscocity to work well with the oil pump
