So, what engine oil grade would you recommend for summer and heavy traffic situations that will increase fuel efficiency and protecting the engine? The car is 3yo and 52k in its odo. Just like Bony_ahmed Im considering to switch to 0W40 if it is safe and can satisfy those aims.

thanks a lot in advance.

Hi, just use 5w30 conventional lube oil (non-synthetic) if you live in Cebu City area.. I am a native of Cebu too but currently my family is in KSA.. Cebu City driving, you cannot exceed 100kph at most you are driving at 60-80kph and normally you are in traffic areas. So to save money better use dino oil and replace it every 5000km, that is simple, it doesnt hurt your pocket... But if you plan on travelling daily just like i do for +100km then i suggest to go for fully synthetic 5w30.

The manual says to use 5w30 for vios/yaris 1.3L in our region.
