Curious about the characteristics of engine oils

Hello,

I just read two 5W30 engine oils specs and was curious to understand the numbers, yes I search on google but cannot really understand
Are higher numbers for instance in viscosity at 40 and 100c° better?
One is a total 5W30 INEO and the other one is the Mobil1 5W30

Sorry I forgot to put the pic, here it is

 

what is the question ??????????

the ARE NOT any brand name B a d oils !!!!

pick ONE USE GOOOD filters............. stock is just fine
few actually better

settle on a schedule change that matches Correct daily usage

keep on truckin !!!

 

Not better, or worse. As long as they fall into the range that the engine is engineered for, they're fine.
