How to Solve High Fuel Consumption in Older CR-V Models?
2 Answers
Once damaged, it will cause an imbalance in the engine's air-fuel ratio, leading to a sudden increase in fuel consumption. Replacing the oxygen sensor can resolve the issue. If not replaced for a long time, incomplete fuel combustion can occur, increasing engine carbon deposits and fuel consumption. Therefore, the three filters should be replaced regularly.
As someone with over a decade of car repair experience, I believe the high fuel consumption of older CR-V models may be caused by engine carbon deposits or aging components. Worn spark plugs can lead to unstable ignition and incomplete fuel combustion; a clogged air filter reduces air intake, forcing the engine to work harder; low tire pressure increases rolling resistance; and a faulty oxygen sensor can affect the air-fuel mixture ratio. The solution is to start with the basics: perform regular maintenance, changing the oil and oil filter every 5,000 kilometers; check tire pressure yourself and keep it at the manufacturer's recommended level; if you frequently experience jerking while driving, promptly visit a professional shop to clean the fuel system and injectors or replace faulty parts. For older cars, don't overlook the details—using higher-quality fuel and occasionally driving on highways can also help clear carbon deposits. These minor adjustments can save you some money on fuel; otherwise, long-term neglect could lead to doubled fuel consumption, which wouldn't be cost-effective.
