Do you change your own oil? Have you actually looked at the oil? Redneck I completely disagree with all your "expert" opinions from a bunch of garbage internet sites.

You don't need to be a mechanic to understand -- it's very simple, changing every 3000 ensures the cleanest oil and the best performance. If that means nothing to you, than by all means change it every 6000 miles.

Hell I bet most people could change it every 10,000 and be just fine. I plan on keeping my JK for life, so I change it every 3000 miles..and its some dirty stuff. And I don't even ride it that hard. I do it because I've seen how dirty my oil gets and I CAN tell a difference in how it performs when I change it. Maybe you can't, but I can.

I agree that changing every 3000 isn't 'required', but to call it a myth and act like anyone who changes it every 3000 miles is an idiot is just plain garbage.

The bottom line here, in my opinion, is that its best to change it at 3000. Changing it more often can never hurt anything. However, the opposite can. That's my

 

I have to agree with JackMacOKC

The only way I would go beyond 3,000 miles for a change is if I have the oil analyzed and did so every 1,000 miles. Then looking at the Data decide when to change it. However it would probably be cheaper to just change it at 3,000 and be done with it.

As the previous person said you CAN'T hurt it by doing at 3,000. However all the dirt accumulated from the last change it in there riding around in the oil. You can't tell me that isn't contributing to atleast some extra wear.

I each his own. Mine doesn't have the lifetime warranty so I am changing it.

 

This is one of those topics that will get as many opinions as types, brands, and weights of oil. I think everyone has a little validity to their statements/opinions/expert advise. 3000 miles in many cases is excessive these days. Can you do harm by changing oil sooner than later (i.e. at 3000)... hell no... clean oil is a good thing. Will changing your oil at 5-6-10K be hard on your engine... maybe/maybe not... If you're concerned then get an analysis... that will give you the straight up facts. If you don't want to mess with that, change it at the interval that you feel comfortable with that is within the guidlines of your warranty. And if that still leaves you feeling slightly uncomfortable, take the age old conservative approach of changing it at 3K.

 

I never said "expert" on anything. I simply am referring to what the CHRYSLER OWNER'S MANUAL says in black and white. Toyota recommends 5K intervals, Ford 7500 intervals, so 6K is in the ballpark. If you're going to mod an internet site and offer "advice" on a public forum, it needs to be correct. I can back up my "opinion" ALL DAY LONG with FACTORY RECOMMENDATIONS. But, as you say, the 3K oil change is your OPINION. Since it's in black and white in most EVERY domestic auto manufacturer's owner's manual for nearly twice the 3K and MORE, that is FACT enough for me. I won't argue with you on this again. Remember, you're the one who said you were an idiot, not me.

 

The question I have is...

Mine is an early 07. My Owners manual says in Black and White for severe use to change it at 3,000 miles. What changed in 08 to allow for 6,000?

Is 3,000 absolutely necessary no.... Am I "Wasting Oil" Maybe ... But I am following the manual that came with mine. For the piece of Mind I will keep doing at 3,000.

 

My Lexus IS300 manual recommends twice a year oil changes

 

My manual says 10000km

 

Lastly, I'll leave yall with this article. It is hardly "internet garbage", but make your own minds up. There's some truth to both sides of this argument, but clearly, auto manufacturers agree that 3000 miles is too often. The best bet is to just follow what's in your owner's manual.

Improvements in lubricants, engines extend guidelines

DETROIT -- Most major automakers agree: The adage that you should change your car's oil every 3,000 miles is outdated, and even 5,000 miles may be too often.

Ford Motor Co. became the latest manufacturer to extend its oil life guidelines, making public that it is raising the recommended oil change interval from 5,000 miles to 7,500 on its newly redesigned 2007 models and all subsequent redesigned or new models.

The company, like many other manufacturers, said Tuesday that higher oil quality standards and new engine designs were responsible for the change, which affects vehicles driven under normal conditions.

"The oils have advanced a lot since the days when 3,000 miles were the typical oil drains," said Dennis Bachelder, senior engineer for the American Petroleum Institute, an industry organization that sets quality standards. "They're certainly more robust than the oils of 10, 15 years ago."

These days, motor oils start with a higher-quality base oil than in the past, and they have more antioxidants that make lubricating properties last longer and other additives that keep deposits from forming on engines, Bachelder said.

Pete Misangyi, Ford's supervisor of fuel lubricants, said the company conducted numerous fleet and laboratory tests with newer oils before it raised the interval.

"That allows more comfort, if you will, in extending the intervals using the new oils," he said.

Some manufacturers, such as Honda Motor Co. and General Motors Corp., have stopped making recommendations on all or most of their models, instead relying on sensors that measure oil temperature extremes and engine revolutions over time to calculate oil life and tell drivers when to get the lubricant changed. Oil can lose its lubricating properties if it runs at too low or too high of a temperature.

Peter Lord, executive director of GM's service operations, said oil can last 12,000 miles or even more for many drivers who don't run their vehicles in extreme heat or cold or tow heavy loads.

"It really does depend on the individual customer and how they've used the vehicle," he said.

Ford said it has found that its customers like a set mileage for service rather than wait for a sensor to tell them what to do.

For those who don't believe the sensors, Lord says GM has reams of data showing that they're reliable, and they notify drivers far in advance of when a change is necessary.

"We are absolutely confident of the technology. We back it with a 100,000 mile power-train warranty now, so there's no doubt in our mind that this technology works," he said.

The longer oil life can save customers money. Ford estimates that drivers would save $600 over a five-year period by going from 5,000 miles to 7,500 between oil changes.

"From an environmental perspective we can save an enormous amount of oil," Lord said. "There's no point in wasting precious oil changing it prematurely. And we don't have to dispose of so much waste oil, either."

When to change oil is not without controversy, though.

Toyota Motor Corp. reduced its change interval from 7,500 miles to 5,000 in 2004 in part because it found that more drivers ran their vehicles under severe stop-and-start and short trip conditions that cause oil to deteriorate more quickly, said company spokesman Bill Kwong.

Toyota also had an oil sludge buildup problem on less than 1 percent of its 1997-2002 model year vehicles, Kwong said. Changing the oil more frequently prevents the sludge problem, which he said was caused by owners going more than 7,500 miles before changing oil.

The company lengthened warranty coverage on the affected engines to handle the problem, even before some owners filed a class action lawsuit, Kwong said.

For some engineers and mechanics, 5,000 miles is too long .

Drivers must take the weather and how much freeway driving they do into account before deciding when to change their oil, said Danny Beiler, part owner of an auto repair garage in Sarasota, Fla.

Freeway driving is less harmful to oil than driving in the city, but in Sarasota, the heat places nearly all cars under severe driving conditions that warrant more frequent changes, Beiler said.

"I have a problem with telling people 7,000 because you know they're going to go over that. I'd rather err on the side of being cautious and tell them to do it early."

Dewey Szemenyei, marketing manager for passenger car motor oil additives for Afton Chemical Corp., said he still changes the oil in his 1998 Toyota Sienna minivan every 3,000 miles.

"I really feel it's great insurance," said Szemenyei, whose company makes additives that go into motor oils and who chairs a Society of Automotive Engineers committee on engine lubrication.

"There's not what I consider a right answer. However, if you go with the owner's manual recommendation you should in general not have any problems," he said.

 

6K is per Chrysler to keep lifetime warrenty = 6k oil changes for me. I do use Mobil 1. Have not had a car in my 38 years of driving that I could not get 200K out of the engine. Typically something else died such as my current Ford Sporttrakl with 180,000 miles, transmission appears to have died today.

 

Since I went to synthetic in my vehicles, I change at about a 5,000 mile interval. Is it ok to change at 3,000 - of course. I just watch the oil to see how dirty it actually is, and adjust accordingly.
