Do these oils affect car warranties? If an owner’s manual recommends oil
changes at 4,000 miles, will the car warranty still be in effect if I use
Mobil Clean 7500?
|
 |
Since the Mobil High Endurance Motor Oils exceed industry and car builder
requirements, drivers can rest assured that their engine is well protected. As
long as drivers follow the oil-change-interval guidelines set forth in their
owner’s manuals, they won’t have to worry about voiding their warranties.
ExxonMobil stands behind the performance of its products. Per the guarantee
listed on the back of the bottle, if a vehicle should suffer a
lubricant-related problem while using Mobil Clean 7500, we will provide
reimbursement for required repairs.

Do the products meet GF-4 specifications? How did the new specification impact
the development of the high-endurance product line?
|
|
The appropriate viscosities of Mobil Clean 5000, Mobil Clean High Mileage and
Mobil Clean 7500 all meet the stringent standards of ILSAC GF-4.
Mobil 1 Extended Performance contains extra performance additives to deliver
exceptional performance and protection. This fully synthetic technology is
designed specifically for longer service intervals and surpasses the GF-4
engine protection and durability requirements. The appropriate viscosities of
Mobil 1 Extended Performance are ILSAC GF-4 certified, and also meet API SM/CF
and various ACEA (European) specifications. (Updated March 2006)

What formulation differences exist between Mobil Clean 7500 and the synthetic
blend, Mobil Drive Clean Plus, introduced in the spring of 2003?
|
|
While Mobil Clean 7500 is a new formula, there are similarities to Mobil Drive
Clean Plus Synthetic Blend. Both formulas are a blend of premium conventional
base fluids and a high-performance synthetic fluid. Also, both formulas offer
an extra level of cleaning agents versus our conventional oil..
Regarding differences, Mobil Clean 7500 guarantees 7,500 miles between oil
changes and is formulated to exceed the requirements of ILSAC GF-4 and API SM.
Mobil Drive Clean Plus is an ILSAC GF-3/API SL formulation. Mobil Drive Clean
Plus will no longer be offered.

What is the Mobil High Endurance Motor Oil line of motor oils and what does
it consist of?
|
|
This line of high-endurance engine oils, designed to provide protection during
today's longer oil change intervals, includes four products -- Mobil Clean
5000, Mobil Clean High Mileage , Mobil Clean 7500, and Mobil 1 Extended
Performance.. Each product in this complete line of oils is guaranteed to
provide protection from lubricant related engine failure for up to 5,000,
7,500 and 15,000 miles, respectively. Mobil Clean 7500 is a synthetic blend
formulation with a boosted level of cleaning performance, 18 percent beyond
the level of even our premium Mobil Clean 5000 conventional motor oil, to keep
your engine cleaner longer.

What type of testing has ExxonMobil conducted to validate these high-endurance
claims?
|
|
ExxonMobil tested these oils in a variety of rigorous field, bench and lab
tests such as field testing with the Lucky Cab Company in Las Vegas, Nevada.
Mobil Clean 5000 and 7500 technology has been tested extensively in various
vehicles, under both normal and severe conditions, such as the Las Vegas
desert and urban city streets, to prove that the products deliver outstanding
performance and protection. Mobil 1 technology has a long history of extended
service performance and is approved by several leading car builders for oil
changing ranging typically from 10,000 to 18,000 miles. This includes
Mercedes-Benz, BMW, Porsche, Audi, VW, Cadillac and Chevrolet. These products
have been tested under the most severe service conditions and ambient
temperatures, and some of the more challenging engine configurations.

|
What was the sample size of the test vehicles? Were these test vehicles
representative of the U.S. car population? What types of vehicle engines were
tested?
|
|
Over 130 vehicles, both domestic and imported, including 4-cylinder, V-6 and
V-8 engines, were tested across the U.S. in real-world driving conditions as
well as very extreme conditions, from the congested streets of New York City
to the heat of Las Vegas.

If I go longer between oil change intervals, do I need to change my oil filter
more frequently? Or do I need a special filter?
|
|
Continue to change your oil filter when you change your engine oil. Special
filters or more frequent oil filter changes are not required.
Mobil 1 Extended Performance Oil Filters provide outstanding performance
during longer oil change intervals. Mobil 1 Extended Performance Oil Filters
are designed to offer excellent efficiency (remove more engine oil impurities)
and high capacity (60 percent greater capacity than conventional oil filters)
which make them ideal candidates for longer oil change intervals. (Updated

Were competitive brands included in testing of the Mobil High Endurance Motor
Oil line? If so, which brands and how did they perform compare to the Mobil
products?
|
|
We do not cite competitive brands that we test against. This line-up has set a
new standard in oil change intervals. We can assure you that the products were
tested against quality products that are representative of branded competition.

|
|
Were these tests and results conducted and validated by an independent third
party?
|
|
In many cases, our additive suppliers actually conducted the testing. This is
very common in our industry and deemed an acceptable practice. Of course, this
is in addition to the already extreme testing completed by ExxonMobil
engineers. (Updated March 2006)

Are these products appropriate for new vehicle engines?
|
|
The appropriate viscosities of Mobil Clean 5000, Mobil Clean High Mileage and
Mobil Clean 7500 all meet the stringent standards of ILSAC GF-4, the latest
industry requirements for new vehicles.
Fully Synthetic Mobil 1 Extended Performance is designed specifically for
longer service intervals and surpasses the GF-4 engine protection and
durability requirements. The appropriate viscosities of Mobil 1 Extended

|
Have Mobil Clean 5000 and 7500 and Mobil 1 Extended Performance been tested
over the long term in cars on the road?
|
|
The Mobil Clean technology was field tested extensively during the last
several years to substantiate the performance of the products. We have
significant long-term testing of Mobil 1 in extended service applications,
both on the road and in chassis dynamometer testing. Field research testing
for Mobil-branded motor oils is an ever-green project and field testing is an
ongoing project that continues year after year. (Updated March 2006)

To achieve the best peace of mind related to engine protection, many vehicle
owners change their engine oils every 3,000 to 4,000 miles. Is this practice
rendered meaningless with the advent of the Mobil High Endurance Motor Oils?
|
|
Consumers should follow the maintenance practice that is best for them, and
that meets their car manufacturers’ warranty. They can have peace of mind
knowing the guaranteed performance and protection intervals of the Mobil line
of high-endurance motor oils. Mobil Clean 5000, Mobil Clean High Mileage,
Mobil Clean 7500 and Mobil 1 Extended Performance protect critical engine
parts from lubricant-related failure for 5,000/7,500/15,000 miles --
guaranteed. (Updated March 2006)

|
Will the use of high-endurance oils have a positive impact on the environment?
|
|
Mobil Clean 5000, Mobil Clean 7500 and Mobil 1 Extended Performance are
marketed based on what consumers are currently doing -- going longer between
oil changes. However, if less used oil is discarded through the introduction
of these products, this would represent a positive impact on the environment.

|
If my warranty calls for a GF-3 rated oil, will using one of the new GF-4
rated oils invalidate my warranty?
|
|
No, GF-4 oils are backward compatible to ILSAC GF-3 and GF-2. This means that
you can use new GF-4 oils in any application calling for a ILSAC GF quality
oil.
