I have a 2010 KIA 1.4 L gas engine. It has 137,000 km. I use 10W40 oil and it uses 1.06 Liters per 1,500 km which is 0.06 Liters more than normal. Should I switch to a higher viscosity such as 20W50? Is this a sign that my car may not make it to 200,000 km? Thank U to anyone who helps may God bless U.
What is the recommended viscosity? Barely over 100k km and already burns 1L of oil? That engine is crap.

Do not put heavy oil in a modern engine. That's a trick to reduce oil burning in cars like a 1965 Chevy. 21st-century engines have tight internal tolerances and hardware designed for a specific range of oil weights, such as variable valve timing phasers. Using a heavy weight oil can cause more problems. (Even 10W40 would be too heavy a viscosity for most.)
Hyundai/Kia engines are notorious for oil burning and even sudden catastrophic failure. They are not good long-term vehicles. Just keep up with the oil usage and next time don't buy a Hyundai or Kia product.
My '79 Pontiac uses 10W-40 because I drive on the highway a lot and I don't have overdrive, haha.
Perfectly fine for those old cast-iron pushrod V8s, and 20W50 would be OK as well if you were using some oil.
I know, when I changed the oil for the first time ever, I was expecting to use just one oil all the time. Instead, there was an ambient temperature chart and differing oil viscosities based on ambient temperatures, haha. Totally not what I was used to.
