just about everyone does with either an old car or a new car with high mileage.how excessive? is oil consumption.well first thing is to check for oil leaks either underneath the motor or any oil lines feed into the motor .any major leaks would be pretty noticeable.if none are present then one would assume that your motor is burning the oil through the exhaust system .check to see what color smoke is coming threw the tail pipe.blue or black smoke indicates oil burning white will indicate engine coolant burning.in any case some color smoke is normal just depends on how much.so lets say your exhaust smoke is normal still could be burning oil just not a noticeable amount.on average you shouldnt have to add anymore than 2 quarts a month or every 1000 miles .depending on your driving conditions if you are having to add more than this there would be a leak some where or heavy color smoke.keep up on oil changes and always add lucas oil usually 1 quart its alot thicker than conventional oil so it reduces engine wear and will handle any small leaks in the engine components like the pistons and rings.if problem still present get to a dealer or certified mechanic as soon as possible good luck.
have it checked for oil leaks, if there is no oil leaks or small leaks that won`t justify the amount of oil your losing then you engine is burning the oil. it could be stuck oil rings. there is chemicals that you can add to the oil to see if they will free up and stop burning oil. just because you don`t see a lot of smoke out the tailpipe doesn`t mean its not burning oil. another thing to check is the PCV valve as if it isn`t working properly can cause oil burning as well.
Blue smoke is caused from the engine burning oil along with the gas and oil. This indicates an INTERNAL oil leak. An external oil leak is one that makes spots on the driveway. The ticking is probably from low oil or low oil pressure. Id have it checked pretty soon by a professional mechanic. It may be time to spend serious money.
it is nt uncommon to have to top up by half a litre of oil or so between servies. Also the harder you drive the car the more oil it will burn as there is more crankcase wear and also more heat produced. If there is no leak its burning it im afraid, there is no other explanations
My 1993 voyager is like that. It may burn some , it definitely leaks some , and it could be just sending some through the PCV valve. Oil leaks and burning oil causes pollution . If you can fix it with a new seal or a valve cover gasket it is easier than constantly checking your oil. Temperature, trailering, speed, outdoor temperature, and engine RPM all can be factors if you are losing oil. If your engine is a quart down, the engine oil consumption rate doubles or triples. In other words the lower the oil level the faster it disappears. High mile cars will drive for years as long as you add oil when it is needed (keep the oil level between the marks). Fix any obvious leaks. Then determine your oil change interval (3000 miles, 4000 miles, 5000 miles). I change between 4000 and 5000 miles. If i am a quart low at 3500 I add a quart. If I am a quart low at 4500 miles I just change the oil in the car. A good practice is to carry a quart of oil in your vehicle just in case you need it. It is far cheaper to add a quart when needed than to go to the dealer once to maybe fix a problem that they may not be able to find or fix. Older engines (even some newer ones) just use oil , especially in hotter climates. Fix the obvious and carry a quart.
I can't imagine that your car is "burning" all that oil in 20 miles. To be sure, remove the spark plugs and look for a lot of ash or really black/oily plugs. I would say more than likely you have an oil leak. Check under your car for a lot of oil streaking. At that rate it should be everywhere underneath.
If you are adding oil every week; then the vehicle is definitely either leaking oil or burning oil. Providing that it is in fact burning oil and not leaking it; you will need to find out what the faulty component is in the engine so that you know how to go about proceeding with repairs. Performing a compression test and a cylinder leakage test should help you to verify the faulty engine component.
You have to identify where the oil is leaking. Check the spark plugs if it has oil, you may just need to replace the oil seal in the plugs. If you meant actual burning from the exhaust, you may want to check the head gasket and the piston rings if the oil seeps into the combustion chamber.
Try to determine how much is leaking by putting a plastic pan under car overnight..
Typical leak sources are pan gasket, oil plug, oil pressure sender.
If burning oil, it will be obvious at startup and/or from the rear
while driving especially during hard acceleration. Have some drive
behind you to observe. They'll see obvious bluish smoke.
If burning is most responsible, and not much is leaking, you may have worn valves or piston rings.
Both fairly expensive to repair. As a temporary cheap solution, add oil
additive (such as STP or Rislone) to reduce burning (it may slow the
leak a bit too).
