Myths About Synthetics

People have a lot to say about synthetic oils. Unfortunately, it's not always accurate. Let's learn the truth behind some of the most common misconceptions about synthetic oils and your vehicle.


Myth:
You should break in your engine with conventional oil, then switch to a synthetic oil like Mobil 1.

Reality:
You can start using Mobil 1 in new vehicles at any time. In the past, engine break-in was necessary to remove any metal flashing (called swarf) or abrasive material left inside the engine after machining as well as to allow the valves and rings to "seat" properly. Today's engines are built with tighter tolerances, improved machining and under cleaner conditions compared to the engines of 10 or 20 years ago. Current engine manufacturing technology does not require a break-in period using petroleum-based motor oils. In fact, Mobil 1 is installed in the factories of:

Therefore, Mobil 1 is used in a car, even before you drive it off the showroom floor.


Myth:
I need to flush my engine before switching to Mobil 1.

Reality:
No special preparation is necessary when switching from conventional engine oil to Mobil 1.


Myth:
Using Mobil 1 will void the warranty on my new car.

Reality:
Mobil 1 will not void new car warranties, with the exception of the Mazda rotary engine because Mazda does not recommend any synthetic engine oil. Mobil 1 exceeds the API and ILSAC engine oil service requirements for all newly imported and domestic vehicles. If in doubt, always check your vehicle owner's manual or contact your vehicle's manufacturer.

Since most new car warranties call for shorter service intervals than those enabled by Mobil 1, ExxonMobil recommends you to follow the recommendations in your owner's manual while your car is under warranty.

Refer to your vehicle service manual for correct lubricant requirement and service intervals.


Myth:
Mobil 1 requires a special oil filter.

Reality:
While ExxonMobil recommends that you use a high-quality filter, you can use the same type of oil filter that you would normally use with conventional mineral oil.


Myth:
Mobil 1 will leak out of the seals of older cars.

Reality:
Mobil 1 does not cause leaks. In fact, new Mobil 1 was tested in dozens of industry standard and original equipment manufacturers (OEMs) tests to prove its seal performance. It is fully compatible with the elastomeric materials from which automotive seals and gaskets are made. If an older engine is in good condition and does not have oil leaks, Mobil 1 provides the same advantages as it does when used in a new engine. ExxonMobil recommends taking measures to repair the leaks before using Mobil 1. ExxonMobil also recommends following the automobile manufacturer's manual for the proper oil to use.
