2019 Toyota RAV4 XLE Premium FWD
I live in Dubai, UAE. I imported my car from US, according to the manual I should only use SAE 0W-16 oil but the temperature here in Dubai is really high (40 degrees C).
Can I still use 0W-16 oil or should I switch to 5W-30?
Thanks
Double check your manual. There is most likely two different weights for your specific car. 0W-16 and 0W-20.
0W-16 is what is recommended.
You can use 0W-20 in a pinch.
If you use 0W-20, you have to do your oil changes more frequently.
Don't use 5W-30. It's not rated for your engine. It might even be too thick for your engine. The tolerances are so tight on modern Toyota's that a thinner oil like 0W-16 is what works best.
This is true, the manual says I should use 0W-16 and in case of using 0W-20 I should go back to 0W-16 on the next oil change and also I should change the oil filter.
temperature here in Dubai is really high (40 degrees C).
please search the forum. This has been answered many times. All engines run at the same temperature (~90C)
It's also answered in our FAQ. Use the recommended oil.
