it is within factory specs to burn more than a quart of oil within 2500 miles it is also common with oil changes are done at small and quick oil change places that the oil is not filled to the max level making it look like it burns more than it does and not using synthetic oil as required asl makes a difference
Is it really burning it, or just losing it? If you have blue smoke coming out your tail pipe, and oily black spark plugs, there's really not a whole lot you can do about it short of a rebuild of your engine.
It really sounds like a rear main seal leak, or a faulty oil filter.
Your mechanic is spot on. The A4's are notorious for turbo overheating and failure. The oil burn is coming in the TURBO itself and then being distributed to 2.3.4 as a side effect. Your not noticing blue smoke because your catalytic converter is doing its job and the minor smoke being generated is being taken care of in the CAT. If you continue to drive as is you will run a certain risk of catalytic converter damage, cylinder damage from fouling (cylinder wash) build up, sludge, etc. If your mechanic has the knowledge on this specifc model there is a way to test the turbo output and turbo heat generation to absolutely confirm. One last thing. in ANY turbo car its imperative to run QUALITY oils not your local wal-mart brand or no name. Many people are not familiar with the demands on a TURBO engine and oil change facilities pull standard oil from 55 gallon drums via a pump.. so you arent feeding your car properly. The AVG (Audi/Volkswagen) company recommends FULL SYNTHETIC and either Castrol or Mobil 1. I have a Turbo Diesel and use Mobil1 as my choice. The recommended oil for your car via their web page is
4cyl. 1.8Liter Turbocharged Mobil 1 0W-40 A fully synthetic motor oil, Mobil 1 0W-40 with SuperSyn Technology exceeds industry standards and the major leading builder requirements, enabling the product to keep performing well after conventional oils cannot. Mobil 1 is recommended by leading car manufacturers as initial fill
No, it goes out when the oil level is read to be correct. If you have the right amount of oil in the car, your pressure sensor is bad or you have oil sludge blocking the pickup tube at the oil pump. Run some Seafoam in the oil for 100 miles and then change the oil and filter (or if the pressure light stays on, add half a can of Seafoam and idle it for 20 minutes before changing the oil). Repeat 2-3 times and see if it goes away. If not, change the pressure sensor (on the oil cooler - the aluminum block the filter screws onto). If this still isn't a fix, you need a desludging kit from www.ecstuning.com. If THAT doesn't fix it, drop the oil pan and change the pickup tube and filter screen, clean out the pan, and repeat the Seafoam treatment.
I have a 2004 pathy-same car.All paths push oil past the lifters-does not burn oil.I have to add about 1-1/2 quarts in between 3,000 mile oil changes.I check the oil when I gas up and add as needed.Hope this was helpful.
