Synthetic oil does not run hotter and actually when you use synthetic oil in your car or vehicles engine the engine will run cooler as the synthetic oil reduces friction.
Synthetic oil reduces friction and therefore heat.
It is also able to transfer heat faster.
Synthetic oil tends to flow faster which may also reduce heat.
Synthetic motor oil works better in both hot and cold temperatures.
It's more chemically stable so it doesn't readily evaporate or break down in the high heat produced inside your vehicle engine.
The synthetic material can withstand higher operating temperatures without oxidizing (burning) or breaking down.
Mineral-based oils can be heated to a temperature of 250 to 300 degrees Fahrenheit.
The temperature of synthetics can reach 450 degrees Fahrenheit.
The synthetic oil is better for your engine than conventional oil.
Although conventional oil (i.e., mineral oil) can provide adequate lubrication performance, it can't compete with the overall engine performance and protection provided by synthetics.
Synthetic oil is a man-made lubricant that consists of artificially made chemical compounds.
Synthetic oils are typically created from chemically modified materials such as petroleum components, but the base material is almost always distilled crude oil.
Unlike regular car oil, synthetic oil is more refined which can lower friction, reduce engine sludge, and increase engine performance.
It's recommended that you change synthetic oil every 7,500 – 15,000 miles, depending on the vehicle and the brand of synthetic oil used.
Conventional motor oil is refined from crude oil, while synthetic motor oil is man-made using chemical compounds designed to feature the best aspects of crude oil.
As a result, synthetic oil features fewer contaminants, which leads to a lower risk of engine sludge and buildup.
