Change your air filter!
Too many cars on the road today have extremely dirty and clogged air filters choking their car engines, leading to poor performance; micro particles being sucked into the engine possibly increasing engine wear; dirtier oil; coating of air flow sensors which might result in misfires, poor fuel economy and increased emissions.
PCV valves vent toxic gases, unburnt fuel and water which have made their way past the pistons during engine operation into the oil in the oil pan. They eliminate pressure build-up in your engine and help remove contamination from your engine oil. Bad PCV valves, depending on whether stuck closed or open, can cause increased oil consumption, dirtier oil, rough idle, leaking seals and gaskets and sludge. It is necessary to replace them periodically about every 2 or 3 years.
Oil filter is replaced at the time you replace your oil engine oil and is extremely important to keep harmful particles from circulating back into your engine from the oil pan.
