Is it OK to switch oil viscosity?

Keep in mind that a change in viscosity will have an impact on the lubricating film thickness. Changing to a higher viscosity or too thick of an oil can result in internal oil shearing, which is the process of oils pushing past each other causing increased heat and reduced operating efficiency.

Can 5W 30 replace 10W-30?

Performance. Both 5w30 and 10w30 engine oils have a similar SAE rating, meaning that they will perform the same at high or operating temperatures.

Can I switch from 10W30 to 10W40?

So if you change your oil from 10W30 to 10W40 you should take care about the weather in your surroundings. Changing from 10W30 to 10W40 will not do any effect on your engine if you choose right one for the right season. Its totally safe you can go for it.

Can I go from 10W40 to 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.

What is 10W-40 oil used for?

The synthetic 10W-40 flows easily and still maintains enough viscosity to protect piston skirts and bearings when it gets hot. The improved temperature stability of synthetics makes them a better choice for race engines and serious high-performance engines.

What does 10W30 mean?

That’s why you see two numbers on most oils. For Example: 10W30. This means the viscosity is at 10W when the engine is cold and 30 when the engine is hot. Low viscosities are good for cold temperatures (hence the “W” association) because the oil is thinner. Thinner motor oil flows more easily and moves quickly.

When should I use 10W-40 oil?

The 10W-40 engine oil has a thicker viscosity than, say, 10W-30 oil when the car engine is hot. This helps it lubricate older moving parts in high mileage engines while being less likely to leak.

Is 10W30 good for summer?

As a general rule, you’ll get the best protection in the summer when you use a slightly thicker grade of oil, such as a 10W30 instead of a 5W30. Engines need a thicker oil in the summer months because of the summer heat and its effects on thinning the oil out.

Should I Flush my engine before switching to synthetic motor oil?

The main difference between flushing your engine and a normal oil change to synthetics is the rate at which the built-up debris is removed from older engines. If you change to AMSOIL synthetic motor oil without flushing, for example, the detergents in the motor oil will clean accumulated deposits from the engine over subsequent oil changes.

Do I need to Flush my engine before switching to Amsoil?

The oil won’t last as long or protect as well if it must contend with sludge and deposits from the previous oil. By the way, we don’t require use of AMSOIL Engine and Transmission Flush before switching to AMSOIL synthetic motor oil, but we recommend flushing your engine if you want to give it a fresh start.

How to perform an engine flush?

How to Perform the Engine Flush: Step By Step Guide 1 – Engine flush treatment 2 – New engine oil 3 – Container to drain the old oil into 4 – A new oil filter 5 – An oil filter wrench 6 – Pressurized air, which is optional. Park your car in a safe and relatively flat area and bring the engine to full operating temperature.

What does an oil flush involve?

The technician then drains the oil and chemicals, replaces the oil filter and fills the car’s oil reservoir with clean oil. Auto technicians often recommend engine oil flushes as part of your car’s routine maintenance, but regular oil changes make this service unnecessary.
