FYI...When to change your oil......
I'm gonna play by Jeeps rules and go by their Oil Change Indicator System, That way no warranty issues down the road. When the indicator says I need to change it then I'll change it. Most likely my first change will be at around 8000-10,000 miles as I checked it tonite with 4775 miles and it is at 56% life left.
Here's the info from WWW.WK2JEEPS.COM........................
Oil Change Indicator Systems
2008-2012 models (gasoline engines)
The oil change indicator system was introduced on most 2008 Chrysler, Dodge and Jeep models. This system displays a "Oil Change Required" or "Oil Change" message at appropriate intervals on the instrument cluster.
Schedules A and B have long been a part of required and recommended maintenance on Chrysler Group vehicles. One drawback of using these schedules is that customers sometimes end up making a best "guesstimate" of the correct maintenance interval.
With the introduction of the Oil Change Indicator system, that's going to change - customers are automatically notified via the cluster or EVIC that an oil change is required. In addition, the system does away with Schedules A and B and instead combines both into easy-to-use lists and tables.
The Oil Change Indicator system uses the Powertrain Control Module to process a variety of inputs and then decides on an oil change interval. The factors which point toward severe use include the following:
Based on the inputs, at a fixed number of miles since the last reset, the Powertrain Control Module decides on the severity of the operating conditions. If one or more of the conditions indicates severe use, the PCM sends a message over the bus so that the appropriate message can be displayed. If the PCM decides that the normal service interval applies, it waits until additional mileage has accumulated before sending out the request for a message.
The EVIC message may also include A dealership's name and phone number, which can be programmed into the vehicle with a scan tool. However, the dealership must receive the customer's approval before adding this information. Hitting the trip button will temporarily end the message, and it will reappear with the next key cycle. In addition to the oil change, the related items listed in the Service Information should also be performed when service is indicated. All other items will follow a single maintenance schedule with the same calendar/mileage intervals no matter what the oil change interval.
2013-2014 models (gasoline engines)
2013 model year vehicles will be equipped with a new variable automatic oil change indicator system. Operating conditions such as frequent short-trips, trailer tow, extremely hot or cold ambient temperatures, or E85 fuel usage will influence when the "Change Oil" message is displayed indicating service is required. Severe operating conditions can cause the change oil message to illuminate AS EARLY AS 3,500 MILES SINCE THE LAST RESET.
NOTE: ALWAYS CHANGE THE ENGINE OIL AND FILTER WHEN PROMPTED BY THE OIL CHANGE INDICATOR SYSTEM AND UNDER NO CIRCUMSTANCES SHOULD OIL CHANGE INTERVALS EXCEED 10,000 MILES OR TWELVE MONTHS, WHICHEVER COMES FIRST.
Certain maintenance services are now coupled with the oil change indicator system rather than being listed at THE REVISED FIXED INTERVALS - 12 MONTHS / 10,000 MILES. Listed below are the maintenance services that are required to be performed at every oil change interval as indicated by oil change indicator system:
2007 MODEL YEAR AND PRIOR
Separate schedule A (normal) and schedule B (Severe)
2008 MODEL YEAR
New 6 months or 6,000 miles interval maintenance schedule and automatic oil change indicator. Severe condition oil drain interval 6 months or 3,000 miles.
2011 MODEL YEAR
Maintenance schedule revised to 6 months or 8,000 miles (except SRT). Severe condition oil drain interval revised to 6 months or 4,000 miles.
2013 MODEL YEAR - VARIABLE OIL CHANGE INTERVAL Maintenance schedule revised to 12 months or 10,000 miles (Except SRT models and Diesel engines). Fully variable metrage algorithm based automatic oil change indicator system. Improves customer satisfaction and reduces environmental impact. Monitors driving habits, hardware differences and environmental conditions continuously compared to the previous system that did not adjust the oil drain interval beyond 3,500 miles. Supports, "Percent Oil Life Remaining" dash display along with the "Change Oil Soon" and "Change Oil Now" dash display features.
Re: FYI...When to change your oil......
I've always tried to change my oil at 3k miles even if the indicator didn't come on. its just a force of habit
Re: FYI...When to change your oil......
That is the recommendation for your 2008 under schedule B (Severe).
