I haven't had the chance to change the oil but I'll do it soon, I was just wondering, why do you need to change it so much?
How does it affect your car?Why do you need to change your car's oil?
Here's an example why it should be changed.
My dad works for Toyota, selling Toyota and Lexus wholesale parts. He got a call one day for a brand new engine for a 2004 Camry. He said, ';A new ENGINE? WHY??'; The person ordering the engine said, ';Because the owner didn't change the oil for about 20,000 miles.';
Also, what kind of car do you have? I've heard to change the oil every 3,000 miles, sometimes every 5,000 or even more. My car's, a 2007 Mazda3, manual says every 5,000 miles. I've seen some up to 7,500 miles.
Your car is probably not in any danger for being 1,500 over the 3,000 mile oil change but it's definitely something you want to either do yourself or have it done at a shop. You don't want your oil to turn into sludge, either.
I wish I knew who goes around here giving everyone's good answers and advice a thumbs down or two. Losers.Why do you need to change your car's oil?
oil breaks down and becomes contaminated/all the additives get burned off and if you wait too long you may have serious engine problems
One of the byproducts of the internal combustion process is acids which tend to build up in your oil. The acids tend to eat the working parts of the engine. The filter takes out dirt but not acids. The only way to get rid of them is to change the oil.
the oil is the lubricant for the engine and if you dont replace the oil your motor will lock up. and then you willl have to buy a new motor or a whole new car...
internal components inside the engine are constantly rubing against each other which causes wear, small particles enter the oil and these particles increase the rate of ware in the engine.......its like when your at the beach and you have sand on your feet, and when you go to put your shoes back on you can feel the sand rubbing against your skin, so you take your shoes off and wash your feet.
So changing your engine oil = washing your feet
It makes perfect sence.........?????? lol
Your oil serves three purposes. 1: lubrication. Oil provides a barrier between the moving parts inside the engine, preventing wear. The molecules do have a tend icy to break down over time. 2: Cleaning: With a gas engine you will have what is known as blow by, past the engine rings. This blow by contains impurities, some of which is carbon, water, and acids. Given time there will be enough carbons in the oil that it will act like sandpaper to the engine components. The water will destroy the lubrication qualities, and the acids will eat the metal inside the engine. 3: Cooling. Some oil will splash on the cylinder walls, then the rings will scrape the oil off the cylinders. During this process the oil takes some of the heat from the combustion process and transfer it to the oil pan.
Granted there are synthetic oils that will last longer, the molecules will not break down, and provide better cooling, however the oil will still pick up impurities. This is why it is important to change your oil and oil filter. Just changing the filter will not remove all of the impurities.
Oil does three things for your engine. It cools, cleans and lubricates the areas between the moving parts. If you don't change it it will not be able to perform these functions at maximum efficiency. It will break down and the engine will suffer premature wear.
you need the oil of course, a new filter, a drain pan, wrench to take the drain plug out, a couple of old rags, and a oil filter wrench. oil wears out after a few thousands miles and it don,t lubricate as well as new oil and it keeps all the moving parts running smooth like bearings and timing chain just to name a couple.
1. Oil undergoes thermal breakdown due to high operating temperature. When this occurs, the oil becomes less effective as a lubricant. And without a good lubricant (read: expensive), parts of the engine rub together and wear each other out.
2. Oil also contains additives that have the ability to neutralize acids. Over time, these additives get used up and stop being effective.
3. Finally, oil can absorb water, dust and combustion byproducts and also hold them in suspension. Eventually, the oil gets saturated with this stuff and can't absorb any more. Then that stuff remains in the engine and can cause corrosion.
Nick, if you gave a good answer we'd give you thumbs up. All you did was say that it was bad and give a few examples of what happens when you don't do it. The question, however, was WHY IS IT BAD!! Read it before answering and piping up! And yes, one of the thumbs down you now have is mine. And to quote Jack, ';If something I'm saying isn't true, (rips off sleeves)do something about it.';
