Oil questions please, need answers.

[Turqui]

I just got a 2015 toyota corolla, im going to perform oil change.
The car has 51k miles.
Acording to toyota, it uses 0-20
I will like to know if 0-20 is a must?
Im in Florida, very hot during the summer.
Can i use 5-30 or 0-30? Its too much? Any possible repercussions?
I will be using mobil 1
Thanks.

Stick with 0-20w . They know what works best for the car.

The engine was designed to pump thin oil . Thick oil could cause the inlet valves to stay open.

Your manual says you can substitute, and the next oil change add back in.

you can do what you feel is right and the car will run.

SAE 0W20, is recommended. I am in the Heat of the Moment and I am running SAE OW16.
