Oil viscosity in hot tropical climate
Hello! I have a Yaris 2007 sedan 1.5L V4 US version with 190k miles on it. The manual recommends to use 5W-30, but the dealership in Costa Rica is telling me that I have to use 20w-50 due to hot tropical climate. I'm concerned about this because I have read that running ticker oil is bad for newer engines, specially the ones that have VVT-i.
What I am currently using is Valvoline High Mileage MaxLife 10W-30 Synthetic Blend. I change it every 5k miles. A previous owner had this car and didn't know which oil was being used in it, so I'm pretty sure they were putting 20w-50 since it is the standard here, so I swapped it to 10W-30, and the only thing I noticed is that the oil consumption is a bit bigger, it burns like a quart and a bit between oil changes. My car does not burn oil through the escape, and there are no oil leaks. Ths is how the engine sounds when it is cold: https://youtube.com/shorts/Qe3OQspBDKw?feature=share Last edited by ricardo-cr23; 05-18-2023 at 01:08 PM. |
