I recently purchased a 2001 Chrysler Concorde from a fleet leasing company. The car is a long wheelbase version, the car had 76k miles on the odometer. I took the car in to a service shop for a checkup. the service writer recommended an oil change and suggested a synthetic oil due to the mileage. I also requested that they perform an engine flush w/ the MOTORVAC system. The car now has 86k miles on it. I recently changed the oil again (I have run synthetic oil in the past and usually extend the change intervals to around 10k to 15k miles). I always try to use good quality filters such as wix or donaldson. Will the solvents help as well? does the syhtetic oil have additives that may help the sludging. I took it to the dealership for a tuneup and they never mentioned the sludging problem. Any help you can give will be appreciated

Wel, in regards to the sludge that may be posibly in the engine, removing the oil filler cap may provide a small clue as to how much may be built up, if there is any on the inside of the cap then there is more in the engine, if it is clean then it is safe to assume the rest of the engine is also fairly clean. Also how clean does the oil stay on the dipstick after running the synthetic in there after a few thousand miles is another, synthetic oil will cleanse an engine better than conventional oil, if the oil got dark fast is because it's cleaning it out, if it is still a relatively light color but slightly darker than when it was first poured in then it is fairly safe to assume you are not having a sludging problem. The bottom line is to keep changing the oil regularily, even using regular oil will clean the engine, but if it gets dark fast using eithyer type of oil, then change it because the cleaning properties are deminished when it gets that dark, there is no sense in keeping all those inpurities suspended in the oil for any length of time.

Synthetic Will Not Fix The Slugging, But It Will Be Harder To Get Sludg Using It, However Seeing That Hte Car Has 76,ooo Miles On It, Its Not A Good Idea To Change To Synthetic. The Reason For This Is Because The Sludg Has Now Actully Provided Seals In Bearings. If You Change That You Are Risking Cleaning Out The Sludge That Has Now Made Its Home In Some Scoreing ,and Worn Bearings That Were Acctually Helping. You Would Probably Start Te Hear More Ticking Noises. Go To Your Local Autozone And Get A Additive Called Seafom. That Works Awsome..
