• 1.8L Dual Overhead Cam (DOHC) I-4 Engine

  The 1.8L Dual Overhead Cam (DOHC) I-4 engine has two camshafts. One camshaft controls the valves for each row of cylinders. The second camshaft does the same for the other set of cylinders. The 1.8L Dual Overhead engine is powerful and can run at higher speeds. It is ideal for sports cars that need a lot of power. Examples of cars that use the 1.8L Dual Overhead Cam (DOHC) I-4 engine include the Mazda MX-5 Miata and the Toyota 86.

• 1.8L Quad Overhead Cam (QOHC) V-6 Engine

  The 1.8L Quad Overhead Cam (QOHC) V-6 engine has six cylinders arranged in a V-shape. The engine also has four camshafts. Two camshafts control the valves for each row of cylinders. The other two camshafts do the same for the other set of cylinders. The 1.8L QOHC V-6 engine is powerful and has high torque. It is mostly used in high-performance cars. However, the QOHC V-6 engine is very expensive to manufacture.

Specification and maintenance of 1.8 engines

• Regular oil changes

  The engine oil lubricates and protects internal engine parts. Over time, oil breaks down or becomes contaminated. To keep the 1.8 engine healthy, perform regular oil changes. Follow the manufacturer's schedule, usually every 5,000 to 7,500 miles. Use high-quality oil and filters. Fresh oil cleanses the system. It reduces friction and wear on vital components. Oil also traps impurities. Regular changes prevent sludge buildup. Sludge can block passages and damage parts. Clean oil ensures consistent lubrication. It protects against costly damage. Sticking to the schedule is key. Adhere to the recommended mileage and timeframe. This simple maintenance step extends engine life. It optimizes performance. It also enhances reliability. Budgeting for routine oil changes is smart. The cost is much less than major repairs. A well-lubricated engine runs smoothly. It maintains power and efficiency.

  A clean air filter is essential for optimal engine function. The air filter prevents dirt and debris from entering the engine. Over time, it can become clogged. This restricts airflow. It impacts performance. To maintain a healthy 1.8 engine, replace the air filter regularly. Follow the manufacturer's recommendations. This is typically every 15,000 to 30,000 miles. Driving in dusty conditions requires more frequent changes. Inspect the air filter periodically, too. If it appears dirty or discolored, replace it. A clean air filter ensures proper airflow. This maximizes fuel efficiency and power output.

• Coolant flushes

  Engine cooling is vital, especially in warmer weather. The 1.8-liter engine generates heat during operation. To regulate temperatures, the cooling system uses coolant. Over time, the coolant loses effectiveness. It can become contaminated, too. To prevent issues, perform regular coolant flushes.

• Follow the manufacturer's guidelines, usually every 30,000 to 50,000 miles. A coolant flush removes the old fluid. It replaces it with fresh coolant. This maintains the cooling system's performance. It protects the engine from overheating. Sludge or rust buildup can damage components. Contaminants block hoses and corrode the radiator.

• Check and replace spark plugs

  Spark plugs ignite the air-fuel mixture in 1.8 engines. They are critical for combustion and power delivery. However, spark plugs wear down over time. They can become fouled or damaged. This leads to misfires and poor engine performance. To keep the 1.8 engine running smoothly, inspect the spark plugs regularly. Look for signs of wear or deposits. Replace them according to the manufacturer's schedule, usually every 30,000 to 60,000 miles. Fresh spark plugs ensure reliable ignition. They optimize fuel efficiency and power. Avoiding old or faulty plugs is crucial. They can cause rough idling, hesitation, or reduced power.

• Fuel system cleaning

  Over time, deposits can build up in the fuel injectors and intake valves. These deposits restrict proper fuel flow. They affect engine efficiency. To combat this, have a professional fuel system cleaning performed. This is typically done every 20,000 to 30,000 miles. The cleaning removes any deposits. It restores optimal fuel delivery.
