I have 5130 miles on my SLK350, which is almost a year old. I did the break-in period as per the manual. At 3000 miles the check oil warning came on. I took it into the dealer and they added 0.5 liters and said it was basically normal. Shortly after that I was driving with my son, a short drive on a hot summer day. When we stopped he exclaimed "Dad why is smoke coming out of the engine?" Sure enough right in front of my face smoke was rising between the edge of the hood and the windshield on the driver's side. My initial reaction was that when the dealer had replaced the oil some had dripped on a manifold or another hot part of the car and it was burning off.

Re: Smoke from engine
I took my slk into the shop for its 12 month check and oil change. It is about a ten-minute drive from my house. As the service guy was taking the numbers off the car, I got a whiff of burning oil. I had him stick his nose between the windshield and hood on the driver's side where I have seen smoke in the past. He said, "yup, smells like you have a oil leak somewhere". After an hour, they located a leak at a corner of the valve cover nearest the driver.

is is odometer reading?
all cars burn oil if driven real fast, at 80mph, lots.
what i need is ,
1: speeds driven. avg.
2: and what weight, oil , is it hot there, sure, then run 10w-40 oil.
3: how many liters of oil per miles.
some cars go for years, burning 1quart of oil per 3000 mile.s
1L/5000 km to 1L /1000 km. (new car to old)
even more. on older engines.
if the engine runs good, drive it and change oil more often.
check oil at every petrol fill up, and learn what your engine needs
all engine burn oil by design. its a fact.
do an engine compression test.
2 times wide open throttle.
on a warm engine
if lower that spec, 150psi?
then add 1 teaspoon, of oil to spark hole , see if compression rises
if it does, its rings are old.
post the numbers, if all are 150 or more , drive it like you stole it.
half joking there, but drive it. and change oil often and check oil levels
every fill up or every other (depends on reality)
post the compression test readings. only NUMBERS count.
we need numbers and engine size.
The problem is that oil is an organic compound. I know that sounds a little odd but it is a naturally ocuring substance that will decay over time. The mileage is based on normal drivng habits and how fast the oil will break down under wear. Driving less will not make the oil last longer. Older owner's manuals used to tell you 2500 miles or 90 days, whichever came first. Oil today is better quality but the idea still applies. Leaving the oil in your van for 6 or 8 months or longer will do damage because the oil can't do it's job, it is degrading.
I would suggest that perhaps you should look into switching to synthetic oil. While it costs more per quart, it has such a long life that it would probably be less expensive for you.It is a far superior oil especially in terms of tolerating abuse like overheating but it also has superior lasting abilities. It doesn't degrade like regular oil. Most people who use it reduce their oil changes to once a year. Hope this helps.
If you need to ask this question you should consult the service department at a toyota dealership..... but i will save you the time and them the agony.... maximum i would change any oil in any vehicle is 5000 miles (8000kilometers) but as i say it never hurts to do it early. oil cahnges are cheap in comparision to replacement engines. break-in period of a toyota engine is closer to 20,000miles (32,00kilometers) in that time i would recommend replacing the oil at 100miles, 500miles, 1000miles, 2500miles and 5000miles on the odometer (not between changes).. break-in period is the most critical in an engines life. after that, regular oil changes make the difference between 150,000miles and 500,000 miles. I got a '97 rav with 282,000miles and it still runs llike a champ. treat it good and it will run forever... FOREVER TOYOTA....
Some people change oil at 3000 miles,most people don't really care or keep track
I would say 3 times a year,if you drive less than 10,000 per year
4 times a year ,up to 20,000 miles per year driven
Use at least semi or full synthetic oil
Depends on driving style. Dusty roads? Lot of stop and go? Lot of short trips under 5 miles? Then 3000 miles is a good interval. If it's all highway miles then you can stretch it to 5000 miles. Synthetic is always better because of it's resistance to breaking down and loosing it's lubrication abilities. Hope that helps. I'm not sure if it's required in that car.
Lost gas mileage. I would have to assume that you are not getting the require mile per gallon. For example If the car book say 32 miles per gallon. You are getting about 20 to 25 miles per gallon. If you want to improve the your gas mileage then you have to do the required maintenance Oil change every 3000 mile tune up as required Air filter If the wiring spark plug wire is old and crack then it need to be replace. If you park out side and the batteries is about 5 years old have it check If you buy the car new, you will have a car book follow the maintenance routine. If you have done all the maintenance and the gas mileage is low than recommended then take it to a shop to figure out if some thing is wrong or not preforming as it should. I do hope this help you.
I personally hold synthetic oil as the high-standard of lubricants. However quality varies. Without completely flushing I would not recommend use in a high mile engine. "ordinary oils" are far better than they used to be, but begin to break down substantially after about 2500 miles. No dealer wants your car to last beyond the warranty period. They sell new cars! Changing your oil & filter at 3000 miles is reasonable, and not too often. If you are using quite a bit of oil, take care of all external leaks you can. It will help a lot. You can't extend change intervals because of oil consumption. The filter must be serviced regularly or you will cause more internal wear.
