Audi Oil Consumption Issue: Is Your Audi Drinking Oil?

Audi Oil Consumption Issue: Is Your Audi Drinking Oil?

We have noticed an uptick of high oil consumption in Audis.  Some customers are adding a quart of oil for every 250 miles while factory spec is an unacceptable 1,200 miles.  We believe that well-maintained cars with less than 100,000 miles should not consume oil between oil changes.

Something is wrong.

 We have found three common causes for abnormal Audi oil consumption:

  1. Oil leaks
  2. Failed crankcase vent valve (PCV)
  3. Clogged piston rings

We have developed a protocol to help reduce oil consumption.  Most of the time it is effective, however, if any of these three items are neglected or too advanced, sometimes the issues are terminal.

Oil leak repair is paramount in preserving the longevity of all engines.  Most often, and if you are lucky, the upper timing cover and cam magnet seals leak.  The repair for these leaks is a gasket, two seals and an hour or hour-and-a-half of repair time.  Complexity and repair time increase significantly from here.


Your dad’s first car had a PCV valve, which evolved to a crankcase vent valve.  As the engine runs, pressure builds inside it and oil mixes with air.  The vent lets the pressure out and keeps the oil inside.


You can test your crankcase vent valve quite simply.  Start the engine and let it idle then, with the engine running, unscrew and remove the oil fill cap.  A faulty valve will create vacuum pressure and pulling off the cap will be difficult.  You will have a hard time lifting the cap off if the crankcase vent valve has failed.  You might also see excess soot or oil residue at the tailpipe.  The crankcase vent valve is also an easy repair and takes less than an hour.


  • If the engine pressure is not vented, issues will arise (item 1 being most common). If neglected, seals will be compromised as the pressure fights to get out…
  • If the oil is not retained, it is like a leak. It goes out the tailpipe and you have to refill. You can also check this–is there black soot inside your tailpipe? Is it powdery soot or oily residue? Oily usually indicates item 3.

Piston rings can be problematic–sometimes we can clean them so they seal better and reduce oil consumption. Sometimes they are not repairable. If the car has had frequent oil changes at quality shops (i.e. not quick lube shops that use low-quality oil), it is more likely to improve with these measures.

In either outcome, our process is to start with a quality oil change and ring cleaning engine flush. For the oil change process, we’ll use a top-shelf oil like Castrol or Motul’s ring-formulated oil. For the ring cleaning, we use the BG 3-step for this and have had favorable results. We also use BG 3-step on BMW’s cam actuators–Audi owners should not feel alone…

Then you drive your car and evaluate the results. With luck, it will improve, although we’ve never seen it return to as-new performance. 


Your Car After a COVID Quarantine

How sitting impacts a car: getting it back on the road

For many Houstonians, the COVID quarantine and resulting office closures have created a situation where a car has sat unused for long periods of time.  Like people, cars do are not meant to sit around.

A general rule of thumb is that a car should not sit for longer than a month without starting it up for 10 minutes.  This likely will not recharge a weakening battery, but it will circulate the fluids and keep rubber parts supple.

Today’s European Cars is starting to see cars that have not been driven for several months.  To date, all have had simple/predictable issues and only needed a comprehensive service to get back into shape.

If your car will quarantine longer than that, it should be driven monthly--a leisurely Sunday drive will keep your car happy.  If you let your car sit, parts will start breaking down and fluids will go bad.  This eventually will cause issues.

What Happens When You Let Your Car Sit

I don’t like to sit for a long time.  If I must, I get irritable and sometimes stiff.  Likewise, with your car:

  • Batteries go dead
  • Tires get flat spots
  • Gaskets and seals become brittle
  • Small leaks develop
  • Fuel goes bad
  • Engine oil deteriorates and traps moisture/condensation
  • Rust develops in the cooling system

This is not an exhaustive list, but the most common things your car might see after six months to a year of COVID quarantine.

A drained battery will probably be the first hurdle of a quarantined car.  Even though the car was “off” there are still systems drawing power—the clock always marches on, the car’s CPU consumes a little, and poorly grounded wires may continue to draw power.  We call this passive depletion “parasitic drain”.  Colder weather can exacerbate the problem and make it harder for your car to start—the cold reduces the battery’s output and thickens the oil, creatin resistance, and a slow or no start. 

On the quarantine list, the battery is usually the easiest to resolve.  Usually, a good drive or a recharge on a battery charger set at a lower output will cure it. Worst-case scenario is replacing the battery.

Tires lose air while sitting and the rubber on them becomes ineffective with longer periods of dormancy.  They crack and small holes eventually develop—you get flat spots because air is escaping from the cracks. If a car sits on a flat spot for a many months or years, you will ll need to get new ones.

Tires which have gone flat during quarantine need to be refilled to the correct pressure.  If they were old tires before quarantine, they should be examined closely. 

Gaskets, seals and rubber hoses often become problematic after sitting.  When left to sit, they become brittle and snap a little pull. Dormancy causes gaskets and seals to break down and not function properly.  Rubber hoses become stiff and don’t seal like they should; this is especially common with emissions and engine vacuum hoses.

Cars have too many seals and gaskets to review, but there are a few common failures we often repair:

Mercedes – oil filter housing gaskets and vacuum breaker plates

BMW – oil filter housing gaskets, valve cover gaskets and oil pan gaskets

W/Audi – water pump/cooling parts and O-rings, brake vacuum pump gaskets and engine vacuum lines.

Gasoline goes bad; and gas with ethanol goes bad quickly.   If gas is not stored in an air-tight container, the oxygen reacts with it and it breaks down.  Your gas tank and vapor system are supposed to be airtight.   However, the evaporative system is filled with rubber hoses, which frequently do not seal completely and air gets into the system. 

Lightly deteriorated gasoline will make your car run rough, and perhaps trigger a “check engine” light.  Often, simply adding new gas to the tank allows you to drive your problems away.

Heavily deteriorated gasoline will develop a gel-like substance, which will need to be flushed from the system.  It will clog systems and keep your car from running.

Engines deteriorate faster when not being used—even with our top-shelf synthetic Mobil1 oil.   Many drivers assume that because they don’t use their car that often, they don’t need to change the oil as frequently.  It’s actually the opposite—engine heat cycles evaporate condensation moisture which develops from sitting.   It’s the heat of running which helps with the evaporation.  Think of your house windows on a cold rainy morning and a sunny afternoon.  Same principle with a car sitting in the garage or driveway—the temperature changes lead to condensation.

Oil changes are an easy fix.  Do them every 5,000 miles or annually and you will be OK.

Weirdly enough, rust forms faster on cars when they aren’t used. Regular driving slows down the formation of rust on the outside.  When cars are stationary, the oxygen and iron have more opportunity to react and create rust as compared to a car is in motion.

How To Revive A Car That Has Been Quarantined

If you parked your car without preparing it for quarantine, no need to stress too much--you’re in a majority.   Most likely, all that is needed is a little diligence and a service at Today’s European Cars. 

If you are handy and have the tools, there are several things you can do to revive your car:

Check tire pressures and inflate to the PSI stated on the sticker inside the driver side door jam, the tire sidewall or to where you like to keep them.  Also inspect your tires.  If you see cracks, you need new tires.  Don’t forget the spare.

Check the coolant level.  Top off with regular water if needed.  This is always a good practice if you are under the hood.

Check the oil.  Again, a great habit.  If your car does not have a dipstick, look in the manual or on a maintenance screen on the car’s dashboard.  Most cars don’t have dipsticks anymore, but there is a level sensor in the oil pan and a way to access it through the dash.  YouTube is loaded with answers for this.

If you think you need new gas, do not start the car.  Instead, siphon out all the old gas and replace it with new gas. Most cars have an anti-siphon mechanism making this difficult.  A shop like ours will probably remove the fuel pump and siphon directly from the tank.

If you think the gas is probably still good, add a quality fuel stabilizer and let it sit for a few hours to remove any condensation that has possibly accumulated in the gas tank.

Next you’ll need to start the car.  Pay attention when you put the key in—is it like you remembered?  If the engine will not turn over, it’s probably a discharged battery. Try charging it with a battery charger. If a jump-start is required, be mindful of the connecting the positive-to-positive terminals and grounding correctly.

If your battery will not hold a charge once the car is running, you probably need a new battery.  We’ve had availability issues with a few of the Mercedes battery sizes—Mercedes is out of stock.  BMW batteries have always been difficult as most cars had three different sizes specified for the car; however, you should use a battery with the same specifications.  Don’t forget to program BMW batteries or reset codes on other German brands.  Don’t mix AGM and traditional batteries.

When your car starts, it may run a bit rough for a while as it works out all that gummed up fuel. The exhaust also might smell different if the gas is old.  Let it idle normally for 10 minutes. Check underneath the hood and car and for any leaks. 

If any of your gaskets went really bad, you might see some puddles underneath the car.  Make a note of what you see and the colors. Remember, most cars have under-panels, so leaks are not always apparent, and you can connect the position of the leak to the position under the car.

Oil – light brown
Transmission fluid – pinkish, except for some Mercedes, which are blue.  Usually more towards the center of the car
Power steering fluid – pinkish
Coolant – Blue for Mercedes and BMW, pink for VW and Audi.  No German modern cars should ever have green.
Brake fluid – clear and usually near a tire

Monitor the temperature of the car to make sure it doesn’t overheat. Don’t idle too long.  If you notice the temperature gauge rising, turn on the heater and put your blower motor on high.  If it still continues to rise, turn off the car immediately. 

If you notice leaks, we can help.  It is never 100% safe to drive with a leak of any sort, so you’ll have to assess whether you can drive it to us or use a tow service.  It all depends on what is leaking, the severity of the leak, and how much fluid has leaked.

We’ll probably start with an oil change and assess your car with our inspection process.  Each one of our techs has more than 10 years of experience; we can review a car efficiently.  Unless specified otherwise, we’ll review your car, build an estimate, talk to you for approval and complete the work as instructed.

Today’s European Cars offers a 24-month or 24,000 mile warranty on our repairs.  We call it the “Longevity Guarantee”.  We can do this because of the quality parts we choose and our benchmark workmanship—it gives us the confidence to offer this warranty to our

Audi Service Center Repair Maintenance Houston

For 100 years Audi has produced high-quality, luxury cars built to last for hundreds of thousands of miles. The safety and endurance of an Audi comes from state-of-the-art German engineering, but after it leaves the showroom, it is up to the owner to provide ongoing care that will nurture their car to its fullest potential.

Finding a reputable garage for your Audi service can make the difference between owning a car for a few years and driving something impeccably special that becomes a valuable and cherished extension of the family. Regular servicing done the right way will ensure the value of your vehicle and save you from unnecessary repair costs and hassles down the road.

Choosing a facility that specializes in Audi for your Audi service and repair needs is imperative for proper maintenance of your Audi. Garages that are geared toward European car repair and servicing such as VW, Mercedes, Volvo, and BMW will use genuine OE (original equipment) parts that will keep your Audi 100% genuine. According to Audi manufacturer guidelines, OE parts are required for all warranty protected work. Audi technicians are trained specifically on Audi diagnostic procedures with state-of-the-art equipment that will uncover any problems or potential trouble spots that cannot be detected with the naked eye.

When planning for your Audi service, it is important that you discuss your options with your Audi technician as to what particular type of service schedule works for you. A full service is usually done once a year (every 12 months) or every 12,000 miles, whichever comes first. Manufacturer guidelines vary, as some may require more frequent checks. Your Audi technician will know exactly what is required by Audi and your make of car. The next service option is called interim service which is performed every 6,000 miles or 6 months. Drivers who do a lot of short, urban stop and go type driving should go this route in order to keep their Audi maintained between full servicing. Interim service is also necessary for those who undergo very high mileage on a regular basis. Lastly, if you haven’t driven your Audi in while, it is always important to get it serviced due to problems that occur specifically due to non-engine use.
What to Expect at Each Audi Service Interval

Audi requires synthetic oil which last longer between oil changes (every 10,000 miles). However, changing the oil at 5,000 mile increments is a “cheap insurance” for a high performing vehicle like Audi.

Other fluid checks include checking the levels of your brake fluid, engine oil, coolant, brake and power steering fluids.
Checks on lighting, brakes, signaling and clutch will also be performed, as well as, reading of onboard auto diagnostics.
Air filter checks and replacements and spark plug checks and replacements.
Windshield wiper fluid checks and function checks
Belt and hose checks

One last thing to note is when you find an Audi service center that you like, make every effort to stay with them and develop a full service history. This is a highly sought after source of information that will ensure you get the highest return value from your car.

We are conveniently located in Houston TX just west of the Galleria, and service mainly the Memorial, West University, Mid Town, Heights, Sugarland and Bellaire areas.
