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.
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.
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
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.
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
