- Friction causes the temperature of an object to increase
- Heat means temperature increases
- Therefore, friction causes an object to heat

- Friction causes an object to heat
- Oil is used to decrease the friction among parts in the car engine
- Hence, oil can be used to decrease the heat among parts in the car engine produced by friction

So, oil can be used to decrease the heat among parts in the car engine produced by friction
Question

Context
- Friction causes the temperature of an object to increase 
- Oil is used to decrease the friction among parts in the car engine 
- Heat means temperature increases
