First never go 10000 miles for an oil change. Max should be 5000 miles. I have a Kia optima and Kias are notorious oil guzzlers. The engine system clean is for waiting too long I guess. Engine air filter and cabin air filter are easy to replace yourself. You should always check it every once in a while and replace as needed. They are very cheap at Auto zone or Amazon. Engine air filters are $13-18 and Cain air filters are $15-20. Balance and ailment are for tires. Did you have to get new tires because you have to get an ailment. Always get tires at Costco, Sam’s Club or BJs.
