Another advantage of platinum spark plugs is that they run a little hotter, which burns deposits off the spark plug better and helps prevent fouling. Platinum also handles high heat, enabling the spark plug to wear better. Platinum spark plugs come in two varieties - single and double platinum.
Found in many passenger vehicles, hot spark plugs have more insulation to transfer the heat slowly, which keeps the temperature high enough to burn off carbon deposits and avoid premature fouling. This helps allow for more time between spark plug changes.
Indeed, iridium spark plugs are generally considered more durable than other kinds of spark plugs (like platinum ones). Nonetheless, they're not invincible and can still foul and corrode. Oil, fuel, or carbon can foul iridium spark plugs just like platinum.
Oil fouling occurs when oil is allowed to enter the combustion chamber. Oil deposits cover the spark plug which can keep the spark from arcing across the gap. Instead it takes the shorter path to ground through the oil. Usually a sign of advanced engine wear.
Each valve has a stem that fits into a guide in the cylinder head. If the guides or seals are worn, oil can enter the combustion chamber and foul the spark plugs. The engine will also consume oil and you may notice smoke from the tailpipe (often when the engine is first started).
Wynn's Stop Smoke is an oil soluble supplement designed to reduce exhaust smoke due to oil burning. Applications: For petrol, LPG and diesel engines. For cars with excessive blue/grey exhaust smoke due to oil burning. Especially effective in older engines with worn components.
Untrue. A leaking engine will leak the same amount of either. Unless an engine is a real oil burner, it will burn less synthetic than regular. Myth: Synthetics void warranties.
Iridium spark plugs are better at starting engines than other types of spark plug because the spark is highly concentrated in the central electrode, and consequentially requires less voltage to operate. This makes ignitions faster and more reliable, and also reduces power consumption.
Iridium Vs Platinum: Which Is A Better Plug? A platinum plug may be harder than a copper spark plug but an iridium plug is the hardest among the three! The iridium spark plug can last longer than platinum by almost twice the mileage, reducing the need to replace a bad spark plug every 60,000 miles.
Platinum has a higher melting point and is denser than copper, making it an excellent choice for long-lasting replacements. What spark plugs are better than iridium? Iridium spark plugs are at the high end of the scale. However, a double iridium electrode offers excellent durability.
When making spark plug heat range changes, it is better to err on the side of too cold a plug. Running too cold a plug can only cause it to foul out, whereas running too hot a plug can cause severe engine damage.
Overflowing engine oil can also lead to bent engine rods and collapsed valve pipes. Spark plug fouling – Excess oil can find its way into spark plugs, which will then need to be replaced.
In some cases, using a higher viscosity motor oil can help fill the widening gap between the rings and cylinder wall, reducing oil consumption.
Oil Smoke Stop reduces the oil consumption of gasoline and diesel engines via the piston rings and valve guides. It prevents blue smoke and oil mist and acts against the loss in viscosity in motor oils.
If your engine is low on oil but there isn't a leak, that means it's probably being burned inside the engine. A bad PCV valve is a frequent culprit in the case of burning oil--but what is it, exactly? A PCV valve is designed to let air escape when the pressure in the crankcase is too high.
Idling your car or truck longer than is necessary causes it to burn more oil. The longer you let your engine run, the more motor oil circulates and burns. That means spending more money on more frequent oil changes. Excessive idling also decreases your car's performance.
Oil making its way into the spark plug wells will drastically affect the engines performance, leading to misfires, increased oil consumption and blue exhaust. In extreme cases, it can even lead to an engine fire. If the vehicle is exhibiting any of these symptoms, the spark plugs should be inspected immediately.
Specifically, if the PCV valve malfunctions, or is stuck open, it allows some of the oil that is used to lubricate the pistons and cylinders to escape. This wayward oil can then find its way to the surface of the engine's spark plugs, resulting in a condition known as “oil fouling.”
