Re: Oil Change Interval - Article in USA Today

Seeing as how the manufacturers make their recommendations (and even program the vehicles to pick a schedule based on the driving style), the oil and filter makers are telling us the 3K interval is overkill, and the only folks still pushing the 3K interval are either those charging you for the service or people who say "well, it's better safe than sorry," I think I'll stick to the book on mine.

I just don't see any valid reason beyond "it doesn't hurt" to stick with the 3K interval if such an interval isn't recommended by the manufacturer.

Re: Oil Change Interval - Article in USA Today

So what should I do if my Jeep tells me to change the oil at 3500 miles? Reset the sensor and wait until 8000 miles?

Re: Oil Change Interval - Article in USA Today

Just had the oil & filter changed at the dealer I bought my WK2 from. They reset the oil change reminder and put a sticker on my windshield that told me the next change was due in 3,000 miles or 3 months. I think I'll go with the manual and change at 8K or 6 months.

The way the vehicle computer works in the Jeep is very similar to most other vehicles with maintenance reminders. That is, it tracks your driving style and selects a given maintenance schedule based on what it deems appropriate.

With the WK2, the oil change intervals are either 8000 miles (regular duty) or 4000 miles (severe duty). The maintenance reminder will trip at 500 miles before the designated interval (in order to give you plenty of warning.

If your reminder comes up at 3500 miles, it is because the computer deems you to be "severe duty" and therefore has you on the 4000 mile interval. In other words, when it dings at you, change it.

The article is reminding us that the 3000 mile interval is a relic of older days, looser engines, crappier fluids and fuels, smaller crankcases, and a generally harder life for the lubricants. Today's engines, lubricants, fuels, and engines gives our oil a charmed life by comparison. Keep in mind that the larger crankcases also play a part- in the past, an engine the size of the Pentastar might only have a 4 quart crankcase. The Pentastar holds SIX. More oil means the contaminants (of which there are fewer) are spread through more oil, and the oil itself gets more time to "rest" and cool down, prolonging life. If the manufacturer recommends longer intervals, there's not much need to do 3K mile changes. If 7500 or 8000 mile intervals unnerve the owner, then by all means go with the severe duty schedule if it gives peace of mind. But just getting it done when the notice pops up is just fine.



Rich mac, my dealer also puts on stickers showing 3000 mile intervals. I remove them and go with what the computer says. Of course the dealers want a 3K interval; if you are like me and the vehicle deems you to be on the 8K interval, that has you in the dealership almost 3x as often, and that's 3x the opportunities to sell other unnecessary services (methinks they don't make much on oil changes, but on other things, it's like free money).

I was planning on having it done every 4K anyway...methinks that the V6 engines work pretty hard to haul this vehicle around, and I plan on doing some towing with it as well.

Re: Oil Change Interval - Article in USA Today

I got my Overland in October and it only has 2250 miles on it, basically it is a weekend car. I have not gotten the oil changed yet. So do I wait the 8000 miles or should I get it changed soon, based on the fact it is 8 months old.

Re: Oil Change Interval - Article in USA Today

Manufactures are pretty conservative. I change oil annually or about every 15-25,000 miles, using Mobile One and high quality filter, and have run several engines over 200000 miles without issue when the vehicle was sold/donated for scrap. Engines still not using oil or showing much signs of wear. The engines would likely have gone 300000 miles if they had a car under them. I used to send oil out for analysis and when contaminants reached a certain level made the change. I don't do much stop and go and no short trips, so the oil stays pretty clean over a long period of time. Using pure synthetic means no acid or sludge build up, minimum oil break down. Sludge can be a killer and some asian made engines are sludge monsters.

My daughter on the other hand gets oil changes every 3000 miles, whether she needs it or not, and has run into more wear problems because of under filling, overfilling, or forgetting to put oil in... poor quality oil or filters.... I dunno.

Couldn't possibly be poor driving habits could it? My neighbors daughter redlines her Honda Accord for minutes on end every morning on cold days to "warm it up faster" and not only does it run poorly, it smokes a bit of blue (less than 20,000 miles on it). Just food for thought.

Re: Oil Change Interval - Article in USA Today

A timely thread for me. I am going to have my oil changed at 1K the first time. I have not decided yet after that. 5K? My question is, what kind of oil is in my Jeep now and what kind of oil should I use from now on? Also, I think I am not going to bring my jeep back to the dealer for maintenance. I have a local garage that I like, but do you have any info that may change my mind? Any thoughts and advice is much appreciated!

Re: Oil Change Interval - Article in USA Today

I change the oil in my cars once a year when I get my car inspected. I have been doing this for 15 years and never (knock on wood) had an oil related issue. My Altima had 140K miles when I got rid of it, my Fusion has 80K miles, my old crown vic is now my mother in law's car and it had 80K on it. I put 19K on my fusion last year on the same oil. I looked at it when the guy I go to changed it and it looked just like all of the other oil he changed that day.

My Jeep started yelling at me to change it before I went on my trip last week. I now had 5200 miles on it but the beep at startup is getting annoying. I have a free oil change from the dealer so I may take it in to get it done but I hope there is a way to do away with the oil change beep in the future.
