What Causes High Fuel Consumption in Camry?
3 Answers
The reasons for the increasing fuel consumption in Camry are as follows: 1. Temperature impact causing fuel consumption fluctuations: Generally, in winter when temperatures are low, fuel consumption tends to increase, almost comparable to using air conditioning in summer. This is because lower temperatures cause the engine to dissipate more heat. 2. Lack of regular vehicle maintenance: Dirty engine oil and air filters can also lead to increased fuel consumption. Dirty oil results in poor lubrication, increasing resistance in the engine's moving parts and requiring more energy to overcome this resistance, thus raising fuel consumption. 3. Spark plug replacement needed: Spark plugs are often overlooked. Even if they can still function, worn spark plugs may cause delayed ignition due to insufficient energy, missing the optimal ignition timing.
Ah, I've been driving my old Camry for ten years, so I'm all too familiar with this issue. A sudden spike in fuel consumption is most likely due to severe carbon buildup in an older car, especially the oxygen sensor—if that gets dirty, it can easily burn an extra two liters of fuel. A clogged catalytic converter is even worse, as restricted exhaust flow directly increases fuel consumption. Another common issue in older cars is carbon buildup clogging the fuel injectors, which disrupts fuel delivery. I once had a full fuel system cleaning at a shop, including carbon removal and oxygen sensor replacement, and my fuel consumption dropped immediately. Oh, and never cheap out by filling up at sketchy gas stations—poor-quality fuel burns incompletely, meaning you're just 'wasting' gasoline. Also, check your tire pressure; underinflated tires can make them 'consume' more fuel. One last thing: for cars over 100,000 kilometers, regular carbon cleaning is a must.
When I was fixing cars, I noticed that many Camrys had high fuel consumption simply due to minor issues. Low tire pressure is the most common—just inflating them properly might save you a liter of fuel. A clogged air filter is like a suffocating mask for the engine, forcing it to work harder and burn more fuel. If the spark plugs aren't firing efficiently, incomplete combustion wastes fuel. A blocked fuel filter restricts fuel flow, making the engine 'eat' more. Some people even forget to close windows on the highway, increasing drag and fuel consumption. Oh, and pay attention to the seal ring when refueling—a loose gas cap can cause fuel evaporation before you even use it. Also, avoid turning your back seat into a storage mountain—extra weight means extra fuel. These small details add up, so DIYers should check these areas first.
