10 or 15 years is a time for a new car. So no need to care so much! 🤣What is your engine type? I asked the dealership techs as well and they gave me the standard well it's thinner so it's more efficient. Personally, I think 0-20w is a little thin for a turbo engine, but they engineered it with that in mind. Amsoil, Redline, liquid Molly, are all better oils if you want something with better performance. If you are just looking for something during summer heat, add a bottle of water wetter or purple ice.
