what are the consequences of not changing the motor oil in my car every 3000 miles.?

Answer 1

If it is a new car under warrantee you may void the warantee...that is expensive. It will run better igf you change the oil regularly as the manufacturer requires.

Answer 2

in accordance to the California air components board and the vehicle makers you in elementary terms replace oil each and every 3000 if youpersistent your motor vehicle short distances or in fairly grimy circumstances. changing oil at this low miles is dropping reliable oil if youpersistent usually. examine your vendors handbook. maximum now say 5000 miles or 6 months minimum. the Carb mentioned that the 3000 mile drain era basically wastes completely reliable oil and provides to pollutants. The oil is so plenty greater helpful now, which you may stick to the recent vendors handbook innovations. 5000 is the advice on maximum non synthetic oils, and finished synthetics are reliable for no less than 10,000 miles.save some funds, and save the planet by utilising stretching your oil to a minimum of 5000 miles.

Answer 3

Motor oil accumulates sulphur and nitrogen from the hot exhaust gases as they get blown by the cylinder rings during the combustion cycle.

When you shut off the engine, the engine cools down, water vapor in the oil pan condenses into liquid, and the water, S and N molecules combine as weak concentrations of sulphuric and nitric acids. These acids are not helpful to the soft metals in your engine - particularly the crankshaft and camshaft bearings, and other soft metals like steel timing chains.

Other exhaust by-products accumulate in the engine oil, such as carbon from unburned fuel. The detergents in most motor oils keep the carbon and other solids suspended in the oil, so that they don't remain on engine parts but are flushed when an oil change is done. Motor oils contain a small amount of an alkaline (base) to neutralize the forming of the above-named acids.


If you wait too long between oil changes, the oil viscosity thickens into sludge and builds up in various places in your engine.

At some point, the sludge makes it nearly impossible for oil to circulate in the oil galleries, so your engine becomes starved of the lubrication needed to prevent metal-on-metal wear and to remove the heat of friction.

Bearings melt, rotating parts stop rotating, and very quickly you have a 4, 6 or 8 cylinder paperweight.


Change your oil and change your filter as recommended by your car's manufacturer.

Answer 4

Probably none if you do change it every 5000 or 7500 miles. Look in your owner's manual. Many manufacturers recommend this interval. The 3000 is a scam invented by auto shops and service centers. Many newer cars only require changes every 10,000 or 15,000, but do require the more expensive synthetic oils. I have never changed oil every 3000 and every car I had ran great at over 100K miles when I sold it.

Answer 5

Voiding the Warranty WILL NOT happen unless the owner's manual recommends a 3,000 mile interval. Stick to what your owner's manual recommends for maintence. They will typically give you the "normal" and "severe" schedules. Most people's habits (city driving, short trips, cold climate etc) tend more toward the severe side, so it is probably better to err on the side of caution and stick with that.

You can always check the color of the oil as well when you fill up with gas. If it looks clean, it is fine. I still recommend following the owner's manual.

Answer 6

The oil is still in good shape at 3000 mi., the oil filter is what you have problems with first. 5000 mi is about as far as you should stretch the maintenance intervals. However, if your car is still under warranty anything over 3000 could void the warranty.

Answer 7

I'm not kidding when I say some have gone over 10,000 miles on pennzoil conventional..... oil analyisis was fine..

conventional oils can go much further than 3,000 miles..... more around 5-6, and 6 months. Though it really depends on your driving style..
Change it a little later.... well less money in they're pockets.... more in yours and the engine doesn't care.

Answer 8

There used to be an add on TV that is to the point. i.e pay now or pay later, your choice. So depends on how long you plan to keep the car. Oil gets contaminated with gas, water, dirt etc. The oil not only acts as a lubricant but as a coolant as well.

Answer 9

Sludge build-up, added wear of engine components, shorter engine life. That sort of thing.
