Anyone know the reason that we have to change oil every 3000 miles.
It will always lubricate because it's oil so why do we have to change it?

i don't know why people change their oil every 3000 miles.. oh wait, i do... car companies and oil companies.
A non-synthetic blend motor oil can probally go around 4000-5000 miles before needing a change
A Synthetic motor oil is reaching it's prime lubricating form around 3000 miles. You can probally go 10k+, but should change around 7500-9500 (depending how hard you've been working your engine).
The CHP (california Highway patrol) uses a synthetic oil, and changes their oil every 10k miles. I think they would know a thing or two about car care..... though not a lot

Depends on how you drive. If you drive highway mile over 30 minutes each trip you should be ok with 5000 miles. If you drive short distances in the city you should change your oil every 3000 miles. I just got a new car and am considering synthetic oil, I heard you change the oil every 10000-15000 miles. Is this true?
Ps-my old Junker car I don?t give a rats a$$ about, I haven?t changed the oil this year. I'm about to donate it and don?t want to put any money into it. It runs fine, wouldn?t do this to my new one.

Always surprises me when this topic comes up, I think that it's only in America that oil changes are so frequent. All European cars have a service interval these days of 10-15,000 miles. Many, my BMW included, have service interval indicators that tell you when it's due, based on driving conditions etc. Mine averages 14,000 miles between services, uses synthetic oil of course.

Any proof the CHP does this, or just another word of mouth urban legend?
Roger that, my month-old car's trip computer is telling me that the first service is due in another 14,500 miles- and it's done 4,000 already. :shocked:
Are you guys sure that your "service" lights include oil changes? Even with synthetic, you shouldn't be running much more than 7500.
Edit: the oil may be good for 10-15 on a clean engine, but the filter will warrant it by 7500 .. not to mention these are new cars with engines you are breaking in ...

Very true, and it's really quite worrying me that the car reckons it won't need an oil change until then. Even though it's a diesel, 18,500 miles without a change is pretty damned long.
Still, it's a company car and they pay all the bills etc, so I'll leave it to them to sort out. I might ring the Renault dealership and ask them, though I have a feeling that they'll be as useful as a chocolate teapot.
You should change the oil as often as is recommended in the car's user manual. More frequently, if you make lots of short journeys, or spend a lot of time idling.
I'm not aware of any manufacturers that recommend oil changes more frequently than every 10,000 miles under normal conditions. Many now recommend 20,000 mile intervals.

Yea follow the manufactures words... :roll:
"Doug had to spend $5,000 to replace the engine in his 2000 Sienna minivan after just 24,000 miles of use. Gregory of Lilburn GA had a similar problem with his 1998 Sienna. He had to replace the engine at 60,000 miles and, like Doug and about 3,000 others, got no help from Toyota, which said he had not maintained the vehicle properly.
The sludge problem occurs when oxidized oil builds up in an engine. Its forms a mucky goo that can cause the engine to seize up. Because the problem can be caused by failure to change the oil. Toyota has been refusing to cover repairs under its five-year/60,000-mile power train warranty. "
Unless you are using a GOOD Syn. like Mobil1 (NOT Castrol Syntec) and/or driving most of your miles on the highway, then 3K is cheap insurance.
