why changing your oil is important

[Gibson486]

I hate my altima so much.....Infact, I hate it so much, that I purposely neglected to give it an oil change for about 17k miles.....it still runs pretty well, but when i accelerate hard, i hear this metal to metal sound, but i think it id related to my air conditioner.

Be glad you have a car... soon to be had a car... :evil:

I run 5K oil changes.. my runs like a champ..

Because Oil will sludge up (become tar) and break down inside of an engine, eventuely the oil will totaly fail to do it's job. I have seen a car die prematurely becasue the owner did not change the lubricant on a regular basis.


Oil sludge is gelled oil that clogs or fails to lubricate engine parts, potentially leading to engine failure. The passageways in many parts of the engine are much like human arteries which can clog when the fluid which passes through them thickens, becoming slow moving and eventually obstructing those passageways. When these vessels become obstructed engine parts can fail, often requiring a complete engine replacement.

Oil sludge can do significant damage to a vehicle's engine in a relatively short period of time. Some consumers have reported oil sludge problems at as low as 20,000 miles and were told that their engine had to be completely replaced. The problem of oil sludge does not seem to be unique to one manufacturer's vehicles, though statistics do indicate that certain makes and models may be at a greater risk for developing this problem.


The Engine on the left in this picture is in serious mechanical trouble, the one on the right has has had frequent oil changes with 192,000 miles on the odometer and looks brand new.

you like letting yourself get pwn3d by "mechanics"

Sorry but that site is full of BS.

You can't tell about oil qulity by looking at it. The picture that has black oil and says "BAD" is wrong. I have changed oils in diesels that look like that but I know they are good to go. Hck black means the oil is working, if it was not dark/black then that means the dirt is sticking to the engine.
Also the emission part. Check air pressure? How does air pressure in my tires increase or decrease my hydro-carbon number or any other part of my emission test? Also do NOT put premium gas in a car that does not call for it. Doing that may in fact increase some emission output if the car is a very low compression car, like most.
I can keep going. Some of the stuf is ok, but there is to much BS to make reading it worth it.

just use high mileage oils. swell the seals and such.

Amsoil + Wix oversized filter = no maintenance for 15K miles

For the value-minded, nothing beat the TropArtic dino ($1/qt) + Supertech Ecore filter.

I think I know what he meant by keeping the tires inflated. Fully inflated tires will not cut emissions when you are at idle (i.e. sitting still while getting your tailpipe metered), I think what he meant is when the car is in motion it will spew out less polutants when fully inflated.
