Yes, old gas can cause the check engine light to come on. Over time, gasoline loses its volatility and can form gum and varnish deposits that clog fuel injectors and diminish engine performance. This can lead to incomplete combustion, which might trigger the check engine light as the vehicle's onboard diagnostics detect irregularities in the engine operation, such as misfires or emissions exceeding regulatory thresholds. To prevent this, it's recommended to not let fuel sit in a car's tank for too long, ideally using it within 3-6 months. Adding a fuel stabilizer can extend this period, especially for vehicles that are not used frequently. Always address the check engine light promptly with a diagnostic to prevent potential further damage to the vehicle.
There are various ways to determine the engine size of your vehicle. The owner's manual typically lists this information and it can also be found under the hood or on a label or sign on the engine itself. Another option is to check the vehicle identification number VIN. which is usually located on the driver's side dashboard. The 8th digit of the VIN usually indicates the size/type of engine and an online decoder can assist with interpretation. For a more direct approach. you can calculate the cylinder diameter. stroke. and number of cylinders to measure engine displacement. but this requires technical knowledge and equipment. For certain types or older vehicles. engine size is often expressed in cubic centimeters cc. liters L. or cubic inches as a reflection of the space in which the pistons move during operation.
To increase an engine's torque, consider several modifications: First, upgrading the air intake and exhaust system can significantly enhance airflow, thus improving combustion efficiency and torque. Installing a larger or more efficient turbocharger or supercharger can also boost the amount of air in the combustion chamber, increasing power. Tweaking the engine's electronic control unit (ECU) with a remap can optimize fuel and air intake, maximizing torque output. Additionally, reducing engine weight and rotational mass can lead to quicker revving and more available torque. Lastly, upgrading to a higher performance camshaft can change the timing of valve opening/closing, potentially increasing the engine's torque output. Each modification carries its potential benefits and costs, requiring careful consideration and compatibility with other engine components.
