hi brooklyn, the viscosity of motor oil is how quickly it flows
Low viscosity oil flows easier when it is cold but become thinner when it is hot.
olive oil
decreased temperature
Not usually
5w30
SAE 10W30
I understand you can use the same oil viscosity in both motor & transmission on the 2008 harley roadking!
A motor oil with a high viscosity (resistance to flow) like SAE 50, will be your greatest density motor oil. Low viscosity like SAE 20 will have the least density.
motor oil. higher viscosity better for hot weather, lower for winter
Viscosity and additives.
Of course you can but when you do you are changing the viscosity of the oil. Your engine requires a certain weight or viscosity of oil. Use only the weight oil recommended by the manufacture.
