Service on a 2003 fx35 with 120k miles

Hi,
If you do some more research you'll see that 1 Qt per 1K miles is considered acceptable, as the dealer stated....not that I agree either!

You may try replacing the PCV valve and ensuring the valves are adjusted properly.

Also, try a different oil - maybe a different weight may help.

I WOULD replace the O2 sensor as it can affect the amount of fuel that is used and may actually dilute the oil if it's getting past the rings.

Just to ensure the engine is healthy you can get a Compression and Leakdown test down. This will tell you the 'health' of the engine.

Go look on the Hyundai/Kia forums for oil consumption, too. You might come across something specific to your model.

maintenance as in basic? Oil changes depend on the type of oil you use. General idea is about every 5000 miles, air filter and spark plug wires and spark plugs should be checked at 18k miles. not sure how long you've owned the car. The timing belt should be replaced at 100k miles, despite what your dealer says. Earliest at 80k miles.

A service engine light means it's time for an oil change. That light needs reset after the oil is changed. The computer senses the miles drove automatically and says "change my oil, it's been 3,000 miles" A CHECK engine light means it has to get a scan done. Change the oil, it will be fine. It is suppose to do that. Let me know if this helps you.

3,000 to 5,000 for oil changes, 15,000 for fuel filter, 30,000 for transmission, 60,000 for differentials, 100,000 miles for "tuneups".

Change the filter with each oil change. Unless your towing, the tranny filter is usually 60k miles. Check your manual to be sure. Your manual should spell out when maintenance is to be done. If a garage wants you to do some outrageous expensive maintenance, have another garage look at it.

The above "Guru has no idea what he is talking about. The yellow oil light means you need a new oil level sensor, if your oil is indeed full. Its located in the oil pan and costs around $100. Oh, and oil changed are around 15,000 miles, not 6000 miles. When the BMW is due for an oil change or inspection, the display says so. The yellow light is low oil. Please avoid giving advice when you don't know what you're talking about.

Your owners manuel will give you the desired intervals for service. It also depends if your last one was a major or minor service. Minors are usually 15,000 miles apart, with majors being at 30,000 mile intervals.

coolant flush and fill.. differential oil changed out ( assuming you have done trans service already also ) .. driveline (u-joints) and steering linkage lubed , fuel filter(s)..and all belts /hoses inspected ... have fun :)

You should change your oil & filter every 3 to 5 thousand miles. The more frequently you change the oil, the more life you will get out of the engine. Rotate the tires every other oil change. Replace the air filter every 15 thousand miles. Flush the cooling system and flush the transmission (automatic) every 30 thousand. Change the iridium plugs every 90 thousand. There is no timing belt to worry about, that veh has a timing CHAIN. That is basically it.

hi the light is doing its job and telling you that you need the 30,000 mile service
services are A B and C the 30,000 is a C and is a major service
garage prices should be in the rejion of £155 /£200 depending on labour rates as this service involves possible replacement of brake parts as well as changing ALL filteres ,oils and coolant it is not recomended for diy chris (merlin v12)
