To:All Ford and Lincoln Mercury DealershipsSubject:2011 Intelligent Oil Life Monitor (IOLM)BACKGROUND
As part of Ford Motor Company's commitment to increase product quality, build vehicles that are environmentally green, and use innovative technology, we are pleased to announce the Intelligent Oil Life Monitor system. This system will be available on over 90% of the 2011 model year Ford, Lincoln and Mercury vehicles sold. The system uses information from the Powertrain Control Module and an algorithm to calculate the proper oil change interval. The interval is calculated based upon the vehicle operating conditions.
The system uses the Message Center to display when the oil needs to be changed:
- "ENGINE OIL CHANGE SOON" at 5% oil life remaining
- "OIL CHANGE REQUIRED" at 0% oil life remaining
The oil change service interval can range from 3,000 to 10,000 miles depending on the vehicle operating conditions.
INTELLIGENT OIL LIFE MONITOR (IOLM) SYSTEM AVAILABILITY
The IOLM will be available on most vehicles under 8500 GVWR and the all new 2011 model year 6.7L Powerstroke Diesel.
The Fiesta, Escape/Mariner Hybrid, and the Fusion/Milan/MKZ Hybrid do not
use the IOLM system.
- These vehicles have a service interval of 1 year or 10,000 miles.
- They have an oil minder system that does not use an algorithm to adjust the oil change service interval.
- The minder uses a one year timer or 10,000 miles to indicate when to change the oil.
- For Fiesta vehicles only the Message Center will display: "ENGINE OIL CHANGE DUE NEXT SERVICE".
The following list of vehicles do not
have the new IOLM for the 2011 model year:
- Crown Victoria, Grand Marquis, and Town Car
- SVT Mustang (5.4L 4valve engine)
- F-150 with the 6.2 liter V8 engine (Harley Davison, Lariat and Raptor)
- F-Super Duty (except 6.7L Diesel)
- Transit Connect
- Expedition/Navigator (5.4L 3 valve engine)
The normal oil change interval for these vehicles will remain at 6 month or 7,500 miles under normal driving conditions. (except Raptor which will remain at 5,000 miles)
The IOLM algorithm uses a predetermined number of engine revolutions it would take to achieve 10,000 miles and has a timer up to one year. The IOLM then uses inputs from the Powertrain Control Module to adjust the oil change interval according to the operating conditions under which the vehicle is driven. Some examples of conditions that would accelerate the oil change interval are: trailer towing, short distance driving in colder or hotter temperatures, or the use of E85 fuel in Flex Fuel Vehicles
Customers can expect the service interval to be as follows:
- Up to 10,000 miles: Normal commuting with highway driving
- 5,000 to 7,500 miles: Trailer towing or driving with high loads
- 3,000 to 5,000 miles: Short trip usage, driving in extreme cold or hot temperatures
The IOLM must be reset after each oil change/service interval to initiate a new interval cycle, as indicated in the Owner Guide.
Note: Review the Special Operating Conditions section of the Scheduled Maintenance Chapter for exceptions.
OWNER GUIDE CHANGES
Beginning with the 2011 model year there is no longer a separate Scheduled Maintenance Guide for maintenance information.
The Scheduled Maintenance Guide content is now included in the Scheduled Maintenance Chapter of the Owner Guide. The information has been reformatted for all vehicles. A chart is used for reoccurring maintenance items and a table is used for items that require service at a specific non recurring time or mile interval.
SALES AND SERVICE DEPARTMENT ACTIONS
