How often should you change the oil in your car?

I have heard it is suggested to change it every 3 months or 3000 miles and I am curious if it is really neccesary to do it that often? Thanks for your advice.How often should you change the oil in your car?
Yes, you do need to change it every 3,000 miles. I remember my father telling me years ago that it used to be like 9,000 mi or something. lol. The reason you need to change the oil every 3,000 is because the ';Viscosity'; of the oil. Meaning it BREAKS down after prolonged use. When you first put oil into the engine after an oil change, the oil is a thick and light gold color. After a couple of thousand miles the oil becomes a lot less thick and your pistons don't have as much ';Cushion'; or ';Support'; as fresh oil has. For example, 2% milk in comparison to Butter Milk. lol. I researched this a bit on the net and here is the most complete explanation I could find for you. Here is the link.

Hope I explained somewhat. Have a great day.How often should you change the oil in your car?
Read the manual. Follow the mfg's guideline on change interval %26amp; oil viscosity. Meet the API specs. - www.api.org Report Abuse

You can go somewhat longer if you use synthetic oil. Report Abuse

keep in mind the suggestions for ';viscosity breakdown'; are given by??? The oil company. Report Abuse

the oil companies want you to, but reality is it isnt necessary. Report Abuse

Actually, I know old dog mechanics that will tell you to NEVER change the oil. Instead, simply add new oil from time to time to keep the oil level up to the necessary levels. It's the particulate in that builds up in the oil that provides the best protection. Report Abuse

Of course, this is a direct violation of most warrenties. Also, the manufacturer will specify when to change the oil. If the warrenty is your issue, then change your oil based on their schedule requirements, at least until the warrenty is up. Some manufacturers list it 3000, 5000 and even 7500. Report Abuse

no its not. i change it every five thousand or so miles, but it also depends on the condition of your engine if its an older engine 100k miles or more it will break down faster than a newer engine, you can tell what condition your oil is in simply by pulling out the dip stick and if it is still clear your good but if it is black as coffee you need an oil change
If you do a lot of stop and go driving then you need to change it more often 2500-3000 miles. If most of the driving is on the highway you could get away with every 3 months. The best way to be sure is to check your oil regularly. If you check in once a week you will be able to tell when it starts to turn darker in color. Then you could calculate what was best for you.
It depends on how much you drive it. If it is a daily driver, change it at 3000. If it sits a lot, for instance; I have a truck that may be driven 1000 miles a year.( Yes; Year) In a case similar to this you can wait 6 months but I would never wait longer because of the condensation (water) that collects in the oil pan. Hope this helps.
I've always done 3 months or 3,000 miles (usually the latter because I drive a lot). I have a '97 Honda Civic with nearly 200,000 miles and it runs like a champ.
3000 miles or three months, which ever comes first
Every 3000 mi. The manufacturer will tell you every 5000 mi so you can come back to them when the problems begin.
Generally, a good rule is to change it every 3000 miles, if possible. I wouldn't go over 5000 miles, then you are really pushing the envelope.
it all depends on the nature of your, driving. is it normal driving, maintaining speeds of 55 to 65 mph, with out stopping, no ac, nothing in the trunk, or is it severe driving, around town, grocery shopping, dropping the kids off at school, sitting in traffic for 30 minutes, just waiting to get home. typicaly. normal driving, which is very rare, can go 5000 miles, but every one else can usualy only go 3000 miles or less ( three months figure that one out)
You can actually go 7500 miles between changes according to newer vehicle manufacturers.The people who actually make the bottled oil say 3000,tops.Whatever you choose,make sure to change the filter.
Okay,.An oil change for a car could be looked at as the equivalent need in the human body for water.


Water keeps all your blood and tissues free of toxins and keeps you from being constipated too, right? keeps everything moving where it needs to go.


The oil change for a car is necessary for the same principle all the pistons and valves to move freely within the motor. They do this at a very fast rate..if the oil within the motor becomes too dirty it slows down this function and then you have more performance problems.


The life of your car is dependent upon the oil changes every 3000 miles. It's good preventive health!!!
