Why do timing chain tensioners fail?

The most common cause of timing chain stretch is lack of maintenance and regular oil changes. The bad oil can also damage the tensioner which makes the possibility of the engine skipping time or a catastrophic failure even greater.

Can a bad timing chain cause low oil pressure?

If the main bearings are worn, the car will still have low oil pressure. Same if the oil pump is worn out. The timing chain, no, not the cause of low oil pressure. Other causes of low pressure could be the oil pressure relief valve, oil pump, bad oil filter.

Will thicker oil raise oil pressure?

Yes thicker oils will increase oil pressure, but will reduce engine horsepower. Excessive oil pressure may explode the oil filter, damage seals, blow out oil passage plugs or even damage bearings.

Is 5w30 thicker than 10W30?

10w30 is thicker then 5w30 because it has a higher viscosity in low temperatures. The engine oil will flow slower than 5w30 during the cold season. Thicker or higher viscosity metal oil has a better seal compared to low viscosity oil.

Is it OK to use 10w40 instead of 5w30?

Your vehicle does not use 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.

Is synthetic oil better for high mileage vehicles?

High mileage oil is designed for vehicles with more than 75,000 miles. This leads to less leakage and oil burn-off, which can be common in older cars. If your vehicle is high-mileage and high performance, it’s suggested that you go with this type of synthetic oil. Not every car requires synthetic or high mileage oil.
