Engine Oil vs Coolant Temperature – Solid Truth!

It is a commonly held misconception that engine oil warms up faster than coolant. While this may be true in certain instances, it isn’t always the case.

With that said, we are going to explain everything you need to know about engine oil vs coolant temperature so that you can have a better understanding.

Engine Oil vs Coolant Temperature

Engine oil typically takes longer to reach operating temperatures than coolant does, as it is a thicker and more viscous liquid than the coolant in your water jacket. Furthermore, engine oil contains additives which lubricate moving components of your engine while eliminating built-up heat.

In short, oil must reach 100 degrees C (212 degrees F) to properly do its job and burn off condensation that forms within your engine during cold temperatures. If it fails to reach this temperature, you will experience increased wear-and-tear on your engine components.

If you drive your car regularly in cold weather, this could be an issue for you. If the coolant gauge indicates it’s colder than expected, have it checked at a NAPA store by an adviser.

Maintaining your coolant level is essential, as this will reduce the amount of heat it emits into the atmosphere. Your NAPA advisor can tell you whether or not your coolant levels are satisfactory and suggest an appropriate type of coolant for your car.

Modern engine oils are designed to cling to parts of the engine, so that they don’t all drip into your sump immediately after being added. This allows them to circulate better and transfer heat more effectively – especially helpful when your engine is hot.

What this means is that if you don’t start your vehicle immediately after starting it, the oil may take longer to reach the correct temperature – potentially leading to issues in the future. Therefore, it is recommended that you don’t idle your car for extended periods of time.

Advice You Should Follow

You should definitely avoid accelerating your car immediately when cold as this can cause parts of the engine to expand and contract, which isn’t good for either performance or longevity.

To get your engine warm, let it run for a few minutes. This will ensure all moving parts are lubricated properly and also avoid any metal-to-metal rubbing which could cause premature engine wear.

Sometimes you just can’t wait for your engine to warm up completely. So, if this is the case for you, you can start slowly by revving gently and driving slowly for a few minutes; gradually increase speed and revs as needed until your car feels completely warmed up.
