I recently made a post about switching to synthetic, but looking at the answers and information all around i decided that it was not worth it for me.
I have an 115.000 kms (70k miles more or less) 10 year old Honda Fit GD01 (2008) and in the manual says the viscocity of oil recommended should be 10w40.
Where i live we dont have -0C° (32 farenheit) anymore. Last time i remember was the earlies 2000. Minimum temperatures range from 0°C (extreme cases) to 38°C (around 104 farenheit) so I don't know really if 10w40 is the right oil.
I'm thinking about putting some 5w30 oil, but i'm not an expert.
Would you recommend this viscocity for my climate and car or it will suffer from it?
