FAQs for Mobil 1™
What makes Mobil 1 superior to our conventional motor oil?
First of all, the performance of Mobil 1 is more robust, especially in terms of low-temperature pumping and flow. High-temperature stability leading to the protection against deposits is also superior. These attributes translate into less engine wear, to help keep your engine running like new, and a long engine life. Conventional oils lack the performance of synthetic motor oils in the areas of low-temperature performance and high-temperature oxidation stability. Mineral base stocks used in conventional motor oils also contain significantly more impurities, such as aromatics and other undesirable contaminants that cannot be completely removed by conventional refining of crude oil.
Back to top
Is it okay to mix conventional motor oil with Mobil 1?
Yes. Mobil 1 is fully compatible with conventional motor oils, semi-synthetic motor oils, and other synthetic motor oils, should it be necessary to mix them. But the superior performance of Mobil 1 will be reduced by diluting it.
Back to top
Will the use of Mobil 1 void my new-car warranty?
With the exception of the Mazda rotary engine (Mazda does not recommend any synthetic oils), Mobil 1 will not void new-car warranties where an API certified oil is recommended. Mobil 1 meets or exceeds API (American Petroleum Institute) and ILSAC (International Lubricant Standardization and Approval Committee) motor oil service requirements of all new-car manufacturers, both import and domestic. If in doubt, always check your vehicle owner's manual or contact the vehicle manufacturer.
Back to top
Is it true that new engines need break-in periods using conventional motor oil?
That is a myth. In the past, engine break-in was necessary to remove metal flashing or any other 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 much tighter tolerances, much improved machining, and under much 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.
Back to top
Should I follow the "severe" service oil change intervals mentioned in my owner's manual? Does Mobil 1 offer specific benefits under these conditions?
Many kinds of driving conditions qualify your vehicle for severe service oil change intervals, and Mobil 1 is ideal for this service. Severe service conditions can include, among other things:
  • Trips of less than 10 miles
  • Driving in cold weather
  • Idling for extended periods
  • Stop-and-go traffic
  • Pulling trailers/carrying heavy loads
  • Driving in dusty conditions
Under both normal and severe service conditions, Mobil 1 is engineered to provide performance reserves in the areas of sludge prevention, piston cleanliness, wear protection, and high-temperature durability.
Back to top
How often should I change the oil if I'm using Mobil 1?
Oil change intervals can be as short as 3,000 miles or as long as 15,000 miles on some new cars. We recommend that you follow the oil and filter change frequencies shown in your owner's manual, especially during the warranty period. With Mobil 1's high-performance reserves, you can have the confidence to go the full mileage or time frame recommended by the vehicle manufacturer. Mobil 1 is especially suitable for the latest vehicles with extended drain intervals or vehicles with oil monitoring systems that vary oil drain intervals.
Back to top
Can I use an oil supplement and/or engine treatment with Mobil 1?
ExxonMobil does not recommend it. According to the API (American Petroleum Institute) and Alliance of Automobile Manufacturers (AAM), "certified oils eliminate the need for supplemental engine oil additives." In fact, the use of any oil supplement is not recommended by car manufacturers and may void a warranty.
Back to top
Can Mobil 1 be used in lawn mowers, snow blowers, and other small-cylinder engines?
Yes, if the small engines are four-cycle engines that call for detergent-type motor oil. This type of engine has a separate crankcase for motor oil – it's not mixed with gasoline.
Back to top
I like to change the oil myself. How should I dispose of Mobil 1?
You should follow the same environmentally sound procedures that you do with conventional motor oil. The U.S. Environmental Protection Agency's (EPA) guidelines for disposal include:
  • Do not dump used motor oil in the trash.
  • Do not pour it on the ground or down the sewer or storm drain.
  • Place the used motor oil in a closed container.
  • Take it to a service station or a collection location that recycles used motor oil.
  • Do not burn the used motor oil in a space heater.
  • To make it easier to recycle, do not mix motor oil with other substances, such as gasoline or antifreeze.
Locate proper disposal locations in your area. Many Exxon and Mobil service stations will take used motor oil from do-it-yourselfers and will follow EPA-approved recycling practices. Please note that it is acceptable to mix used Mobil 1 with used conventional oil. In short, Mobil 1 should be disposed of in the same manner as used conventional motor oil.

I thought Mobil 1, as a full synthetic, already provided the protection my high-mileage car needs. Do I really need to switch off Mobil 1 to your High Mileage product for my high-mileage car?
Mobil 1 High Mileage is designed for high-mileage vehicles that have been using conventional motor oils. It's true that most Mobil 1 vehicles with 75,000 plus miles should be in excellent condition and would not require some of the Mobil 1 High Mileage benefits. However, most cars on the road today do not use synthetic oils, so we developed this oil specifically for these cars that would benefit from switching off conventional oil.
Back to top
I'm currently using Mobil Super High Mileage with good results. Why should I change to Mobil 1 High Mileage 10W-30, which costs more?
If your vehicle has been maintained well, Mobil Super High Mileage represents an excellent choice. However, if you believe your engine may have sludge through less-than-adequate maintenance practices, Mobil 1 High Mileage may be the more suitable selection. Mobil 1 High Mileage helps reduce the sludge that other oils can leave behind which can result in extended engine life. For severe cases where sludge and other heavy deposits are present, shorter oil change intervals of 3,000 miles are recommended as clean-up proceeds.

FAQs for Motorcycle Oil
What was the reason for the formulation change to the Mobil 1 Racing 4T™ 10W-40?
Mobil 1 Racing 4T 10W-40 is an internationally available product and, as such, represents advanced global technology. With the release of the recent JASO motorcycle standard (MA 2006), an opportunity was presented to again upgrade the Mobil 1 Racing 4T formulation such that it continues to meet and/or exceed the latest industry and OEM standards for motorcycles.
 
Back to top
So how is Mobil 1™ synthetic motor oil for passenger cars different from Mobil 1 for motorcycles?
First, let's be clear about the overall benefits of Mobil 1 synthetic motor oil compared to those of conventional motor oils, whether for passenger cars or motorcycles:
  • Superior long-term engine protection.
  • Superior high-temperature stability.
  • Excellent low-temperature starting.
  • Outstanding engine performance.
  • Low volatility/low oil consumption.
It's a little hard to generalize about the difference between Mobil 1 passenger-car motor oils and Mobil 1 motorcycle oils. That's because not all viscosities of Mobil 1 passenger-car oils have the same levels of zinc and phosphorus, and there are even greater differences among the two Mobil 1 motorcycle oils. In general, Mobil 1 motorcycle oils have:
  • Additive packages balanced differently for motorcycle engine and transmission operation. For passenger vehicles, fuel economy and emission system protection are higher priorities. These require low phosphorus systems and the use of friction modifiers. Motorcycle oils do not require friction modifiers for fuel economy and for better clutch friction less/no friction modifier is optimum. Motorcycle oils allow the use of higher levels of antiwear additives such as ZDDP (phosphorous).
(Updated December 2007)
 
Back to top
What are the overall advantages of Mobil 1 motorcycle oils?
In addition to the overall benefits listed above – specifically, high-temperature stability and low volatility/low oil consumption – Mobil 1 synthetic motorcycle oils also offer superior anti-corrosion performance compared to conventional motor oil, which is important in many parts of the country where bikes may sit in garages for several months of the year.
 
Compared to conventional oils, Mobil 1 motorcycle oils provide superior wear and high-temperature protection, and promote engine cleanliness and lower oil consumption.
 
Once you get past these general advantages, you have to deal with each specific motorcycle oil one at a time to understand the benefits.
Back to top
Okay. Let's start with Mobil 1 Racing 4T 10W-40. What does it offer that Mobil 1 for cars does not?
Mobil 1 Racing 4T 10W-40 is designed for sport bikes. Most of these bikes have multi-cylinder/multi-valve engines and use a common sump, which means the engine oil lubricates the engine, transmission and wet clutch. So unlike Mobil 1 for cars, Mobil 1 Racing 4T 10W-40 motor oil has no friction modifiers, which could lead to clutch slippage.
 
The motorcycle oil also has more phosphorus/zinc for enhanced wear protection at high engine speeds and high loads.
 
In addition, Mobil 1 Racing 4T 10W-40 has a high performance dispersant/detergent technology for better high-temperature performance and engine cleanliness. Mobil 1 Racing 4T 10W-40 is also offered in a different viscosity grade than Mobil 1 for passenger cars. (Updated December 2007)
Back to top
What about Mobil 1™ V-Twin 20W-50 motor oil? How is that different from Mobil 1 for passenger cars?
Mobil 1 V-Twin 20W-50 fully synthetic motor oil is designed for air-cooled, large-displacement bikes. Because of their design, these engines can generate very high localized oil temperatures and high overall bulk-oil temperatures.
 
As you know, a typical air-cooled V-twin's rear cylinder gets a lot hotter than the front cylinder – it's a matter of airflow. When it's hot out and you're stuck in traffic, the oil temperature in your bike climbs rapidly. Above about 250°F, conventional motor oil is going to break down. Mobil 1 V-Twin 20W-50 fully synthetic motor oil is good to above 300°F.
 
Like Mobil 1 Racing 4T 10W-40, Mobil 1 V-Twin has high levels of phosphorus/zinc and the same high-temperature detergent technology for superior wear protection and engine cleanliness, even at elevated oil temperatures.
 
With Mobil 1 V-Twin oil, you can go the full length of the manufacturer's recommended oil change intervals with ease.
Back to top
The owner's manual says I should change the oil every 5,000 miles or once a year. I change my oil every 2,500 miles or twice a year. So why do I need that kind of protection?
For peace of mind and added protection. You pay a lot for a bike these days, so why risk running your engine in ordinary oil? Just like Mobil 1 synthetic oil for cars, Mobil 1 synthetic motorcycle oil helps keep your engine clean – free from varnish and deposits – and smooth running mile after mile, no matter what conditions you ride in.
 
Mobil 1 oil benefits engine life and performance. In fact, the lubrication capability of Mobil 1 motorcycle oil helps maintain peak horsepower and acceleration throughout the life of your engine. And with Mobil 1 motorcycle oils you can go the full 5,000 miles between oil changes.
 
So, if you want to ride your bike long and hard and not be concerned about the oil, choose Mobil 1 motorcycle oil.

Mobil 1 15W-50 is a higher viscosity oil that delivers a thick oil film for protection of high performance engines. While Mobil 1 15W-50 can be used and is recommended for both street and track use, the new Mobil 1 Racing oils are not recommended for general street use where vehicles use catalytic exhaust converters. Mobil 1 Racing™ 0W-30 and Mobil 1 Racing 0W-50 are lower viscosity oils designed to protect the engine under high output conditions in high operating temperatures. Additionally, Mobil 1 Racing Oils offer boosted levels of anti-wear protection (nominal zinc level of 1850 ppm) for extra engine protection in highly loaded flat tappet engine designs like those used in the NASCAR Sprint Cup series.

Are Mobil 1 Racing oils compatible with a wet clutch engine?
These oils are not recommended for wet clutch applications due to their high level of molybdenum.

Are Mobil 1 Racing oils the exact formulation used by the Formula 1, NASCAR, and Le Mans race teams?
Mobil 1 Racing oils are formulated with the same race-proven, fully synthetic technology used in racing applications around the world.  However, typically, Mobil 1 tailors its racing oil technology based on the specifications required by specific teams and/or race applications.

You say that Mobil 1 Racing oils are not for street use.  Why is that?  Does that mean I can't use these oils if my race car is also my daily driver?
Automotive street use oils that meet the latest industry standards are required to have a lower level of Zinc and Phosphorus anti-wear chemistries than oils formulated years ago.  The latest automotive street use engine oils are designed to be compatible with emission control equipment.  Mobil 1 Racing oils are formulated with anti-wear (Zinc/Phosphorus) chemistries at twice the level of automotive street oils to provide enhanced protection of highly loaded valve train systems found in some race engines.  Based on the high level of anti-wear chemistries, Mobil 1 Racing oils are not recommended for street use.

Zero weight oils are thinner.  Will using a 0W oil cause excessive engine wear while racing or qualifying?
Mobil 1 Racing oils employ fully synthetic, latest generation, wide viscosity grade racing oil technology, designed to help reduce engine friction and protect the engine under high output conditions in high operating temperatures. Both Mobil 1 Racing 0W-30 and Mobil 1 Racing 0W-50 motor oils offer boosted levels of anti-wear protection (nominal zinc level of 1850 ppm) for extra engine protection in highly loaded flat tappet engine designs.
