I've been brought up to always believe in the sanctity of the 3,000 mile oil change interval. It's short money and a small investment up front in oil changes will make a huge difference in the lofe of my car's engine.

Lately, however, I've been seeing and reading a bunch of articles like the two below.

Stop Changing Your Oil
and
When Should You Change Your Oil

With 5 cars extending the interval of oil changes could save some serious bucks.

Interestingly, my car's change oil reminder just came on after 2500 miles and this time I reset the interval myself after the last oil change. Second time it's happened. First time I blamed it on the dealer not resetting the system.

What does everyone think?

I change the oil in the Sebring at 5k. My wifes BMW I change it every 10k.

If you really want to find the correct interval send the oil out for analysis

My personal take on this whole thing.... I did not read the articles you posted yet to bias my opinion.

Honestly, I change the oil in our vehicles when I am in the mood. I use to do it ever 3000-3500 miles. Using Mobil-1 or any other synthetic oil, that can get expensive..not to mention Mobil1 has an extended version good for (whatever the jug says), something like 12,000 miles for like $2.00 more for 5 Qts.......So my thought here is, so for about $.40 per quart, you can make me an oil that is good for 3-4 times the mileage of your REGULAR...Yea Right!!!! I honestly feel that the 3000 mile thing is 1.) for good ole pennsylvania crude/refined oils not the newer synthetics. 2.) for the higher reving 4/6 cylinder motors of the 70's & possibly 80's.

For this forum, I assume we are not talking about alcohol funny cars and you don't have Garlits or Force written on the side of your vehicle. Nor do you completely rebuild it after you drive it 1,320 ft. (1/4 mile).

That all said, where do you drive your vehicle, how hard do you drive your vehicle, what environmental contaminations is it subjected to? Example: I had a 4X4 Chevy PU that I drove off road quite a bit and ran it fairly hard in the sandbox type sand found in the Outer Banks of N.C. You guessed it, I switched to synthetic lubricants all through the truck, Grease, Motor, Transmission (manual 5 speed), transfer case and Differential and running in dirt, sand, saltwater etc. I changed all of it after each trip (each trip was usually 1-2 weeks, 2-3 times per year). Gotta love OBX.. :cheers:

I currently change our vehicles oil somewhere between 6-8000 miles using the mobil1 (sometimes regular, sometimes extended, sometimes high mileage..(That is a whole different ball of wax) :rofl: :rofl: Oh yea, that one has special additives to keep the rubber seals in good shape...Oh, so the regular blend is not so good for my oil seals????? Cummon!!!

Bottom line (fer me anyway) watch yer oil, you know how and where it is driven and under what conditions. Mind the mileage, but when it is dirty, change it......BTW run it all through a good filter and it is probably good for much longer than anyone, manufacturer (oil & Auto) our ourselves are willing to admit...Good Lord, when I was youger OK :nono: a lot younger it was good ole regular OIL and ya changed it ever 12,000 miles (agreed it was really nasty, BUT we had STP and Slick 50 to add to the oil.

Bob :blahblah: :soapbox: :cheers:

I use regular Mobile 1 in my GTC. I change it no sooner that 5,000 miles and no longer than 6,500 miles. I got the car with about 37,500 miles on it in September, 2005, and the first thing I did was change from dino oil to synthetic. It now has over 161,350 miles and I've had no problems with this oil change interval. I buy the Mobile 1 when it's on sale at Advance Auto. The cost for 5 qts. and the Mobile 1 filter is in the $32.00 range on sale.

I change mine when it looks dirty...or just before a big trip...My 2012 Chevy Silverado (My work truck) goes 8000 miles between changes (that's when the light comes on) the Baron is now running synthetic and it will get checnged when it looks like it needs to be changed...I've always done this and most of my previous vehicles (of modern times) were sold with no less than 188K on them...most were 250K or so...I have a long way to go with both cars...

I have the like changed in the Sebring every 3500-4000 miles, as the car in city driving most of the time and we live in a very dusty climate. Time frame about twice a year.

The TC however is supposed to go every 8000 miles, so that will be about once a year.

Old School. Don't use synthetic. Change every 3500 to 4000. Never had any issues with internal problems. Most of my driving is city and very short drives. 2.2 miles to work.

The original owner of my car obviously didn't change it enough.

With the newer oils it's a lot saffer to go extended periods of time!
However, look at the vehicle, my GMC truck had an oil sensor that tells me when to change the oil, and has gone as long as 7,000 - 8,000 miles. However, I will change out the filter around 4K and add 1/2 qt. Valves look GREAT @ 70K miles
Now as for the sebring, 1st gen, they have a oil sludge problem, so I replace it every 3,000 miles and I'm OK and at 120K.
Our 96 Jeep with 225K gets a filter change at 5K, and oil chg at 10K or one yr whichever is sooner! Just replaced the VC gasket, and it looks like a new rockers!
So I've extended the time frame when I change the oil, However, I do try and change the filter in between!!

I would agree with the 3,000 mile interval for your 1st gen; but, I've not heard of sludge problems with 1st gens. My understanding is the sludge problem is specific to 2nd gens from 2001 to mid 2003 model years with the 2.7L. Certainly, I could be incorrect about the 1st gens; but, I don't believe so.
