Since my doughter bought this car in 2012 it has used about a quart of oil every 1000 miles. That is not normal by any standards. I've tried lucus oil additive with the 10w30 recommended oil viscosity but it still sucking it up. It dosent smoke or leak a drop and it runs fine-it just eats oil!! Are there any suggestions besides trying to sell it? My e-mail is email@example.com
2006 Chrysler Touring 3.5 V6 uses a quart of oil in 1800 miles. I use Mobile One 10W30. I tried Valvoline and Pennzoil and it seem consume even more oil with those brands. From what I hear this is a common problem and Chrysler doesn't consider this excessive. Also to those who may be having idling problems (rough,surging) this may be due to carbon build up and there is a TSB for that.I used Lucas cylinder and switched to Mobile 89 octane gas ans after about 4 tanks of gas and taking it out and jumpin on it a few times it runs and idles great.
Every 3.5L 300 driver I have talked to (maybe 8 or 9) has the same oil consumption issue. I figure on 2 quarts between synthetic and 1 between regular oil changes. Needs to be checked every month if not more often.
I have the same problem with my 2005-300 Touring, though I use standard 10W-30 oil. I also see the same issue with my 2006 Chrysler Pacifica with the same engine. I have 190,000 on my 300 and 133,000 on the Pacifica. I usually add a half quart of oil at about 2,000 miles and I'm good until oil change. The problem doesn't seem to get any worse.
first it had an oil leak after its first oil change took it back 4 times was told it was the oil filter.Turned out to be the housing was bad. My belief was this year has the metric threads and they where using the standard thread oil filter. I have now taken over the service of the car after what I felt was poor work coming from the dealership after several mishaps. yet the car still uses oil about 2-1/2 qts between oil changes every 3000 miles. Also it is about impossible to remove the dip stick when the motor is hot. I took a trip in the car and drove about a 1000 miles went to check the oil and the dip stick broke as i tryed to remove it.
I've had this car a number of years. The car is consuming a lot of oil. I've been driving back and forth between Raleigh and Concord. I had my oil changed in mid July. This morning I had to put 3 quarts in just to hit the min marking on the dipstick.
My 300 also uses oil my car was dealer maintained the tech put on repair order my oil is low and dirty change more often little did he know I go every 3000 miles so I went to my old mechanic showed me a bulletin that I need a motor thanks Chrysler dealer glad the techs are factory trained this is after numerous complaints. Since about 20,000.miles they yanked my chain for 24,000 miles more. This bulletin goes in to 2013 all models. With this crappy motor after 20 years with this motor looks like jasper motors can rectify this problem but not Chrysler I should check in to it.they could be built in china or Mexico like most of GM motors and trannys
