How is the maintenance of this Pentium B70 15000 km? Can you just change the oil and clean the throttle?

Nothing needs to be changed, synthetic engine oil. You don't have to wipe the gas pedal if you go to the countryside every day. Antifreeze is not changed every year. Use the same brand of antifreeze. If it's missing, make it up. There is no need to change it every year. 15000 km without changing the brake oil. Mainly oil and three filters. The oil and oil filter must be replaced. Air conditioning filter and gasoline filter are not dirty, so you don't need to change them. Only run 15000, it won't get dirty, and it doesn't need to be changed. 40,000 kilometers to change brake oil. Spark plugs, clean carbon deposits and throttle.
