Viscosity, i.e. "thickness"; maple syrup has a higher viscosity that milk, for instance (I must be hungry). Use whatever is called for in your owners manual. It also is often printed on the oil filler cap. Generally speaking, either one will suffice.

read this:

as a matter of fact, there is no such thing as one oil weight, or viscosity, recommended for all cases of driving. you need to look into your driving style and climate. if it's alaska, you want oils that are less viscous, to prevent engine damage at cold starts due to lack of lubrication. and it's visa versa for very hot climates, when even heavier weight oil is more luquidy than a lighter weight oil in alaska.

you want to use oil that has the lowest possible difference between the 2 numbers, thus 5W20 is better than 5W30.

if your car takes no oil, does not leak oil, or smoke oil, or any of that - do next change 50/50 mineral oil and synth oil, and then switch it to full synth after that. amsoil is guaranteed for 25000 miles, for instance, royal purple - for 15000. i have been using nothing but those 2 on all of our non-oil taking vehicles for years, and they all run like swiss watches. pretty much, oil change once a year for royal purple, and in 1.5 year for amsoil. i do roughly 20K miles a year on my personal vehicles.
mobil one is the best filter out there. you can not buy the best-best one, it is for japanese market only. 2nd best is new K&N filter. you always get what you pay for.
