Does the Mobil 1 Extended Performance meet GF-4 specifications? How did the
new specification impact the development of the high-endurance product line?
|
 |
Mobil 1 Extended Performance contains an extra performance additive to help
deliver exceptional performance and protection. This fully synthetic
technology is designed specifically for longer service intervals. Appropriate
viscosities of Mobil 1 Extended Performance also meet all the requirements for
GF-4. Additionally, they exceed the requirements of API SL/CF and various
ACEA (European) specifications. (Updated March 2006)

What is the difference between Mobil 1® Extended Performance and Mobil 1?
|
|
Mobil 1 Extended Performance formulas are designed specifically for today's
longer service intervals and are guaranteed to protect for up to 15,000 miles
or one year.
Mobil 1 Extended Performance has a unique formulation with a boosted level of
protection and performance. Mobil 1 Extended Performance, with the Advanced
SuperSyn System, contains 50 percent more SuperSyn than Mobil 1.

If Mobil 1 Extended Performance is recommended for 15,000-mile intervals,
what’s the maximum limit to which it can be pushed? In other words, if a
driver goes an extra 1,000 miles or so, is he going to damage his engine?
|
|
Mobil 1 Extended Performance is recommended for up to 15,000-mile or one-year
oil change intervals. However, if your vehicle manufacturer recommends an oil
change interval beyond 15,000 miles and Mobil 1 meets the performance level
specified, you can be assured that Mobil 1 will go the distance.

Upon what driving conditions are these performance claims based? Normal or
severe driving conditions?
|
|
These claims relate to all typical consumer driving conditions, excluding
those mentioned below. In other words, if you drive under normal conditions
and use Mobil 1 Extended Performance in your vehicle, the oil is guaranteed to
protect your engine for 15,000 miles. We also recommend that drivers consult
their owner’s manual while their vehicle is under warranty, and follow the
guidelines set forth there. Additionally, we recommend that if consumers drive
routinely in severe conditions that they follow the oil change interval
recommended in their owner's manual for severe conditions. We define "severe
conditions" as:
-
racing or commercial applications;
-
frequent towing or hauling;
-
extremely dusty or dirty conditions; or
-
excessive idling.

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.
However, 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 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 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 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.
