What is so Great About Full synthetic

This engine oil can never breakdown by overheating because, it takes the heat that is generated by the engine. With that said, it keeps the engine running longer as it moves through the engine

All retailers that sell Mobil 1 oil will sell a five quart jug for around $34.00. Which comes out to $6.80 per quart, that also equals $0.21 per fluid ounce.

Mobil 1 helps prevent deposits from building up in the engine (I.e. dust and debris). That is to say, the oil also creates a layer between the moving components of the engine to prevent them from contacting each other, which helps to increase the life span of your engine.

This oil has superior additives mixed into the oil that help to prevent wear and tear on the internal engine components. Where other oils do not lubricate well in colder climates, it takes more force to turn over the engine.

Because of the additives in this oil it reduces the friction of the internal engine parts. These additive help to keep the oil from freezing up in the winter and overheating during normal operation.

Why you Can’t Use the Oil

Mobil 1 full synthetic oil cannot be used in diesel engines, however they do make an oil that is designed for heavy-duty engines. Exxonmobil recommends Mobil 1 Turbo Diesel truck 5w40 for use in these engines.

Diesel engines generate more soot and operate at higher temperatures than other engines. That being said, the need for higher lubrication is needed to maintain the engine.

Something That Actually Happened With Mobil1

When I was a former technician I came a cross a story from the Corvette GM school.

A Corvette engine was mounted on an engine stand, in the engine was Mobil 1 full synthetic oil. This engine was kept at 6,000 rpm (revolutions per minute) for two or three hours straight while class was going on.

After the class, the exhaust of the engine was glowing bright red as the engine was shut down. Now the class went off and did something else.

After that task was done, the class started back up the engine of the Corvette and there was only the sound of the engine running, There was no knocking coming from the internals of the engine.

Furthermore, there was no excessive ticking coming from the engine as well. There was also no leaking coming from the engine after being run at max revs for a long period of time.

After hearing this story, I was sold on the idea that Mobil 1 oil is great for protecting the engine.

From hearing this story to today, I use Mobil 1 in all the vehicles that my family owns.
