The standard is every 3,000 miles or 3 months.
Synthetic oil is done every 5,000 miles or 5 months. Or every other normal oil change.
I have to totally disagree with the above answer. The 3,000 mile oil change is only recommended by people who make money off oil changes. The 3,000 mile oil change was needed 20 years ago but with modern engines, modern oil, and filters it is a waste of oil and money. Look in the owner's manual of almost any vehicle made in the last 10 years and you will see recommended oil change intervals of from 7,000 to 10,000 miles and that is with conventional oil. My recommendation is to change your oil/filter every 5,000 miles with conventional oil and every 8,000 miles if you use synthetic or to follow the recommendation listed in your owner's manual. The manufacture knows way more about this that some Quick Lube shop wanting to make money off oil changes. This is not 1990 and to change you oil every 3,000 miles is overkill.
Most new Ford cars have a service interval of 12,500 miles and a lot of European manufacturers - BMW, VW - have longer service intervals of 15,000 miles or two years and this has led to specially formulated long-life oils for these cars appearing in the shops. However, many people are still distrustful of these lengthened service intervals and will change the oil (and especially the filter) more frequently, and there's nothing wrong with that! But with the price of fully-synthetic oil being a minimum of twenty quid for five litres in the UK - £45 for a premium oil like Mobil 1 - well, we aren't going to throw that away every 3000 miles! And you should still check the oil level once a week - a longer service interval doesn't absolve you from that!
Every oil change.
You should change your oil every 3,000 miles. If you drive your car rough, then you should change it more often.
you should change oil on you car every 5000 miles

Usually the oil filter of the car is changed when the oil is changed. The oil change should be done on regular bases after like 3000-5000 miles or when the car is brought to the garage for a service.
There are 2 answers that should be done together. Change your oil more often, and use a thicker oil.

To keep your car running well, you should do it every 3,000 miles.
Every three months or every 3,000 miles.
Changing the oil is critical to a long lasting car. I change the oil every 3,000 miles. There are various thoughts about how often oil should be changed however, the cleaner the oil, the better it is for your vehicle. My last car had 365,000 miles on it and it was still running. I attribute a lot of that to changing the oil frequently. A car in many cases is an individuals major investment. For the cost of changing the oil, it's all worth it.
This depends on the oil that goes into the car. If it is synthetic you need to change it every 10,000 miles if it is regular than it needs to be every 3000-3500 miles.
It is best to change the oil after every 6000 miles. The most important thing is to follow the recommendations for your car.
