Hello and thank you for using Just answer!
I'm Billy and i will assist you with this.
Feel free to ask if further info is needed.

The difference would be:
- a higher grade (like the one you used = 40), means that the oil has more viscosity, and can lubricate in higher temperature, and is a bit thicker.
- a lower grade (like the one on cap = 20), means less viscosity, lubricate in lower temperatures, a bit thinner.

Since you live in a hot climate, then you may definitely use the 5W-40.....actually it would be better to do so.

Just make sure that you use synthetic (better characteristics and longer life span), you check the oil level on dipstick every now and then, and replace oil and filter at regular intervals (8000 km, for best engine lifespan).

Thank you for trusting JA and myself.......get back to me if further info is needed.....positive feedback and bonuses appreciated...
