Can someone explain the concept of viscoity in great depth. When comparing differing oil weights for example, 5W-20 vs. 5W-30, what is the advantage of using them, say in a climate where the temperature isn't too extreme, but rather mild. Say 72 F throughout the year.

To my understanding, the hotter it is, the more viscous a material is going to be, given use to an everyday example, like syrup or cooking oil.

Can someone explain how exactly is gas consumption/hp is proportionally related to the differing weights of oil used?

Thanks

 

NO WAY!!!!!! A simple search came up with your answer! OMG

Can you read that whole article and explain to me how different viscosities contribute to gas consumption and hp?

I've searched there, and even here: http://hypertextbook.com/physics/matter/viscosity/

Unfortunately they're not motor related....

 

Results 1 - 10 of about 177,000 for Oil Viscosity horsepower

Guess what the first one is...

What search protocal are you, and do you do searches on holidays?
