re oil

Question : If a multi vis oil is rated say 10w 30 does that mean it has the weight or viscosity of 10w and additives to equal 30 weight ?
and if that is true ,,then why do some engine manufactures ,,,and engine require a straight 30w? Why wouldn't a 10w 30 work ? Unless its additives don't add up !!!

And have you noticed its getting harder to find straight weight oils ?

I want to try a mobil 1 , 15w 50 synthetic in a kaw that specs for straight
30 for normal summer heat ,,,,
my understanding is if it runs cooler the less friction, and there for a longer running engine...

I also have a infared temp gauge and can check it under simular conditions
Thanks already rt
