Common reasons for this to happen: Low fuel pressure, dirty or defective fuel injectors, or broken fuel pump: The fuel pump is responsible for transferring fuel from the tank to the engine. Loose or corroded wires in wiring harness: An inconsistently firing ignition will result in an easily stalled engine.

The primary cause is overfilling the non-vented fuel tank. Stop pumping gas into the tank when the nozzle first clicks off. Don’t try to squeeze every last drop of fuel into the tank. A mechanic will need to inspect the charcoal canister for fuel contamination.

There are 6 main reasons that might cause a car to stall while idling, these include the following: Faulty oxygen or mass airflow sensor. Clogged EGR valve. Bad spark plugs.

Common causes of intermittent stalling may include a bad idle speed control (ISC) system, low fuel pressure, loss of ignition, vacuum or EGR leaks, or other problems we’ll get to later in this article. This can lug down the engine and cause it to stall.

Bad performance. Your car may misfire or experience hesitation and stalling. Most cars default to the factory air-to-fuel ratio if the oxygen sensor fails, which can cause problems because of non-standard temperature, moisture, or air composition.

It is commonly applied to the phenomenon whereby an engine abruptly ceases operating and stops turning. It might be due to not getting enough air, energy, fuel, or electric spark, fuel starvation, a mechanical failure, or in response to a sudden increase in engine load.

If your engine has a major problem it will cease to work properly.

1. Pull over to the side. The first thing you should do is remain calm.
2. Try restarting the engine.
3. Call for a tow If you have tried to restart the car and you could not figure out the problem yourself, it is time to call a tow truck.

One of this is an automatic shutoff when the oil pressure drops to a certain level, or the oil level drops too low (note that this is not true for all cars). This causes the engine to stall and die. It’s usually noticed if your coolant is low, but low oil can also cause the engine to overheat.

The vehicle can have idling problems when there is an issue with fuel or exhaust issues. If the pressure is low then you may need a new fuel pump and filter, but should at least change the fuel filter and retest. You may also want to inspect the exhaust system and make sure the engine can breath.

If your car stalls out at red lights, it means that your engine suddenly can’t control the idle. When your engine loses the ability to control the idle, this could be due to several factors, including the following: A malfunctioning or dirty mass air flow sensor.

Symptoms of Low Engine Oil

• Oil pressure warning light.
• Burning oil smell.
• Strange noises.
• Weaker performance.
• Overheating Engine.

When you skip an oil change or go too long without one, the oil in your vehicle is unable to properly move through your engine. Skipping an oil change leads to the vehicle’s oil thinning over time and catching a buildup of metal, dirt, and other particles.

When the oil becomes thin, old, or poorly textured, you might hear the issue every time you drive. When driving with bad oil quality, your engine may make a knocking sound while the vehicle is in motion. Oil issues can also cause other noises, like ticking, which we’ll discuss in the last section.

Motor oil can only last for a certain period of time. That’s why it comes with an expiry date. For this reason, oil goes bad with time just by sitting in the engine. Over time, it becomes less viscous thus less efficient in maintaining proper lubrication between moving components.

Most oils will mix perfectly, provided they have a similar synthetic. Therefore, there is no problem in mixing 10w30 and 5w30 since one will be topping up. Mixing the viscosity of oils will not have any effect on the engine. 5w30 and 10w30 engine oils have close viscosity, and thus there is no harm in mixing them.

Using 5W30 oil for your vehicle will not blow out the engine. Your vehicle runs best at 5W20 and this is the type of oil that is recommended by the manufacturer; I always advise customers to use the type of oil that the manufacturer recommends.

You might notice a few oil spot in your garage or under your car because using the wrong oil can lead to leaks, or you might become aware of a burning smell while driving. If the oil isn’t working as it should engine parts might not be lubricated well enough and cause friction, which can burn the oil.

The only difference between these two oils is cold flow ability: a 10w30 oil will move slower than a 5w30 oil during cold startups. If the oil will be in the engine during winter and you live in a place where it gets cold during these months, use 5w30 oil. If it will only be in the engine during the summer, use 10w30.

5W-30 motor oil is the top viscosity recommendation by automakers over the past four decades for use in many vehicle types. Furthermore, high-mileage 5W-30 motor oil is specially formulated for late model vehicles or newer vehicles with over 75,000 miles/120,000 kilometers.

Newer vehicles can utilize thinner oils for faster lubrication of new engine parts. In contrast, older, high-mileage engines benefit from thicker oils to prevent friction and oil loss.

High-mileage motor oil doesn’t hurt and it could prevent leaks from starting. Some mechanics recommend switching to a thicker (higher viscosity) oil — such as 10W-30 full synthetic oil instead of 5W-20 full synthetic — or using oil additives to stop leaks.

Mobil Clean High Mileage 10W-30 is designed for vehicles with more than 75,000 miles. Its advanced formulation helps protect seals and prolong engine life. These oils protect against sludge and engine rust and corrosion under high and low-temperature operating conditions.

Comparing the Options

A 10w-40 motor oil is a thicker oil at startup than a 5w-30 motor oil. Therefore, 10w-40 oil clings to the engine’s moving parts more than the lower viscosity 5w-30 oil.

The recommended oil viscosity for your vehicle, according to Kia documentation, is 10W-40. If you drive the vehicle in exceptionally cold weather, well below 32 degrees, you can use 5W-30 oil but even 10W-40 is still perfectly OK to use if outdoor temperatures are below freezing.

As posted above, mixing 5w30 with 10w40 will give you an oil that performs somewhat better in the cold than 10w40, but less good cold than 5w30, and that has a viscosity a bit higher than 5w30 but a bit lower than 10w40.

Designed for high mileage vehicles Mobil 1 High Mileage 10W-40 motor oil is recommended by ExxonMobil for use in high mileage vehicles (even those that have used lower quality conventional oils†), including: Cars. Trucks.

Amsoil High Mileage Motor Oil The Amsoil Extended Life Synthetic Motor Oil works well for all engines, although it’s particularly well-suited to higher mileage vehicles due to being designed to stay effective and reduce wear over time.

When you’re choosing the best oil for older cars or high mileage engines, there are several criteria you can look at.

• Pennzoil High Mileage Conventional Motor Oil.
• Castrol GTX Part-Synthetic High Mileage.
• Valvoline MaxLife High Mileage Synthetic Blend.
• Mobil1 High Mileage Engine Oil.
• Amsoil Premium Protection Motor Oil.
