A little more info on LOF service intervals...

Chrysler is non specific about oil change intervals due to the monitoring of the engine oil quality by the pcm. Yes, there is a sensor submerged in the oil pan that monitors the resistance of the oil, along with programmed variables such as idle time, hard drive time, hi speed drive time.. etc.

Thus we have the...

FSS- Flexible Service System

This is the monitor on the dash.

This monitor can recommend an oil change as early as 1500 miles or as long as 10,000! (yikes!) This is based on the above listed inputs/criteria.

Now- I personally change my oil every 3k on my non-synthetic vehicle. Would I go past 5k on synthetic? Probably not. I too have seen our motors abused- and the $5000 estimate to replace a 2.7 would be conservative in a DC 3.2 Benz motor... SO in conclusion:

If the FSS says to change it... CHANGE IT
Can you change it sooner- absolutely!
Would I reset my interval and ignore it? Better have those LOF receipts when you want warranty engine work in my dealership- DC will require it!

By the way... LOF services are not a money maker for the dealerships.... At my dealership we charge 19.95 for a normal oil change. By the time the dealership pays me, the parts guy, the service writer, the porter, the cashier, the management there is not enough money left for the parts! Yes I am telling you we actually lose money on an LOF at 19.95. This is done to keep you the customer coming to us, so when you do need real service, you will come back to us.
