Regen???

[Rotti]

My truck seems to regen once every fill up. That is about every 245 miles or so. I drive 95% highway at about 65-70mph, and when Im putting around town, I try to be very easy on the pedal. I have noticed an elevated amount of fuel in my oil,dealership told me it was normal! Then yesterday I noticed the nasty tapping, knocking sound that I've heard so many people complain about. Then it stopped! Do you guys think there is something wrong with my truck, because it is regening so much with my easy driving style???

Well if your being easy on the truck and your going into regen every 250 miles that might raise some flags......being easy on the truck, regen should happen every 400 to 500 miles, at least thats what I've seen on other trucks.......getting 245 miles to the tank on the highway is not good either......on the highway I can get at least double that, now granted my truck is modified, but 245 seems really bad to me......I've heard different dealers say that the rise in oil level is normal, but what I would do to CYA is to take a sample of your oil and send it off to be tested and show them the test results and ask them to explain....

There are no stupid questions.....regen is short for renegeration mode

This was my thought too.

if that's the case, what does that mean, what does the truck do, what causes the truck to do it?

Regeneration mode is a process in which the truck cleans in the new EPA equipment that is required on new diesels. There is a filter called a Diesel Particulate Filter or DPF on the exhaust, which according to the EPA, is suppose to catch the soot or black smoke from the exhaust.....well like any filter it gets clogged and needs to be cleaned......the truck cleans the DPF by bring the exhaust gas temps or EGT's to over 1200F by injecting more fuel in to the motor and bringing the RPMs to 1200. The EGT's burn off the soot that is caught in the DPF. The process happens every 350 to 650 miles depending upon driving style

Wow! Thanks for the information guys, I will bring it to my service techs attention and hopefully I will get some answers as to whats going on. It will have to wait till next week because I can't get it there right now. Maybe there is more going on than I originally thought. I did ask my service tech about the rise in oil because when it was a week old I had noticed it was high. He said that ford says its normal if it rises 4%. I took his word for it, but it did not sound like fuel should be in the oil to me for any reason. Now that I have this nasty tapping, knocking sound coming from the motor I'm sure they will be taking a closer look at whats going on. Thanks to everyone for your input, and I will reply with more information when I take it in for service, thank god for the warranty.
