Using the wrong oil filter can cause severe oil leaks, loss of oil pressure, and catastrophic engine failure due to improper filtration or oil starvation. Even if the filter physically screws on, internal differences can prevent your engine from getting the lubrication it needs.
Engine Damage: Installing the wrong oil filter on your car means you expose engine components to unfiltered oil or inadequate lubrication. Pistons, bearings, and camshafts wear down faster due to increased friction. Over time, these components can overheat or fail, putting the engine at risk of severe damage.

Under 99% of conditions there's really no difference between 5w20 and 5w30. If the car is stalling, the cause is not the oil. Your engine shouldn't know the difference. You might lose a microscopic amount of fuel economy, but I doubt if you would even notice that.
Using 5W-30 Instead of 5W-40
Using 5W-30 in an engine designed for 5W-40 may not provide enough protection under high stress or heat. Always check your vehicle's owner's manual before making a switch.
5W30 offers better high-temperature protection. It's great for towing, highway driving, or older engines, especially for drivers in Frandor and Lansing who use their vehicles for more than just errands. 5W20 is thinner and generally suited for newer engines that prioritize efficiency.
Technically, you can mix 5W30 and 5W20 oils. Both are multi-viscosity oils, which means they perform well in a range of temperatures.
Increased Friction and Overheating: Incorrect oil can struggle to regulate engine temperatures, leading to overheating and potential damage to sensitive components. Reduced Fuel Efficiency: The added friction and strain on the engine can cause it to work harder, consuming more fuel in the process.
Although 10W-40 engine oil is the recommended oil for most conditions, the oil viscosity may need to change to accommodate seasonal temperature changes. Using 20W-50 oil in higher ambient temperatures may reduce oil consumption. Visit KTECH™ 4-Cycle Engine Oil for more details and to see our oil viscosity guide.
Check your car's owner manual
The first step in choosing the right engine oil filter for your car is to consult your car's owner manual. The manual provides specific recommendations for the type and size of the oil filter that is compatible with your car's engine and oil system.

A common question is whether it's safe to use 10W-30 instead of 5W-30 oil, for example. While it's best to use what's recommended in your owner's manual, inadvertently using a viscosity one grade higher or lower than what's recommended generally poses no long-term harm.
Installing a low-quality oil filter not only can hinder engine performance, but can actually cause engine damage. Each type of engine is designed to work with a specific type of oil filter that meets your vehicle's oil flow, temperature, and performance needs.

Only if your vehicle's manufacturer allows it, check the manual or consult a mechanic, as switching grades may affect fuel efficiency and engine performance. 5W30 generally offers better fuel economy due to lower friction at operating temperatures, whereas 5W40 prioritises engine protection over efficiency.
10 Signs You're Using the Wrong Engine Oil
The presence of oil and its distribution is absolutely crucial to an engines continued operation. Engines can work without oil, but the effect is so damaging they are only capable of running for less than 30 minutes until failing - and in most cases, it's a lot quicker than that.
The recommended oil they tell you to use is what will always be “best” for the engine. However, unless to change the oil every weekend, you will never notice the difference between 5w-20 and 5w-30. Drive it until your next oil change. You will likely notice no difference.
As the engine noise is concerned, the most important property is the viscosity grade. Higher viscosity oils require a higher pressure head to be pumped through oil channels. On the other hand, they build a thicker lubricant film providing a greater sound damping effect.
Opt for thinner oils like 5W20, which flow better during cold starts and help your engine warm up faster. Choose 5W30 or 10W30 if you drive in warmer areas. These oils offer better protection at higher temperatures and are more suited for sustained engine loads.
5w30 motor oil's ability to function in a large variety of engine types and under a wide range of temperature conditions makes it incredibly versatile. Whether you have a light-duty petrol or diesel engine, 5w30 is often the suggested motor oil to use because it flows more easily in winter temperatures.
OLD ENGINES
Over time, the engine components will start to deteriorate. That causes small leaks, meaning the engine will consume oil faster. It is essential to compare the current oil consumption with the maximum permissible oil burning.
