Why Do Porsche Engines Burn Oil?

The M96/M97 engine can experience a wide range of faults, many of which can result in excessive oil consumption. The “Air to Oil Separator,” or “AOS,” as it is frequently called, is the first thing that needs to be investigated. This emissions device connects the oil-filled engine crankcase to the intake manifold in order to circulate crankcase gases. The amount of liquid and vapor oil that can be returned to the intake is metered and constrained by a number of diaphragms inside the “AOS.” As long as it functions as intended, this is fantastic. If it doesn’t, the intake manifold will cause massive amounts of oil to be induced from the crankcase when the diaphragms fail. This causes a “James Bond Smoke screen” to come out of the exhaust pipe. In some cases, the AOS diaphragms will fail less dramatically, and you could only notice a slight increase in oil consumption, slowdown, and a strange whistling or squealing sound coming from the engine at idle. Due to the increased amount of crankcase vacuum inside the crankcase, high speed air is drawn by the engine main seals, causing the seal to vibrate and emit a sound wave.

A common culprit for this is found to be malfunctioning fuel injectors, which lead to over-enrichment due to improper fuel atomization and fuel washdown of the cylinders. The piston rings and cylinders have trouble sealing due to the fuel “wash down.” When the engine is turned off, fuel injectors might “stick,” allowing fuel to drip into the cylinders as the engine cools. This fuel contributes to the contamination of the engine oil and other component damage at the subsequent start-up. If this problem is not fixed, it will result in “bore scoring,” about which you can read in our website’s knowledge base.

Are You Prepared For A Porsche That Burns Oil?

What do you mean am I ready? You might be questioning yourself if you own a Porsche 997, which can guzzle up to 1.6 gallons of oil every 622 miles. Porsche is considering introducing a diesel engine to its US portfolio, starting with an oil-burning version of its Panamera sports sedan and Cayenne SUV. However, Porsche is not talking about increasing the permitted oil consumption levels for its gas-powered flat-six engine. According to Porsche’s Bernhard Maier, both of its two largest vehicles will make their debuts in diesel form at the Geneva Auto Show.

Internally, we are debating whether or not to launch the Cayenne diesel in the United States this year. A Panamera diesel is another choice.

Since 2009, Porsche has sold a 240 HP diesel Cayenne in Europe. According to the European test cycle, this vehicle delivers above 30 MPG combined (non-EPA). Additionally, since the Cayenne and Panamera accounted for 63 percent of Porsche’s sales last year, the company is relying on those two nameplates to increase volume until its new goods, such as the upcoming “baby boxster” and the next-generation 911, are available for purchase. Offering diesels in the US won’t likely result in a significant increase in demand for Porsche’s best-selling items, but it won’t impede efforts to increase their marketability.

Many Americans would adore having an affordable diesel in a light truck (1/2 ton) that provides utility and dependability. Sadly, the Porsche Cayenne fails to deliver on both fronts.

What’s one more bite off the loaf when Porsche has ALREADY destroyed nearly every link to its founding background as a manufacturer of solely lightweight sports cars?

I suggest, bring the oil burners here. To partially atone for its corpulence, EVERY elephantine jumbo-SUV should have either hybrid or clean diesel technology accessible. Probably best to include a diesel Panamera as well.

Through Consumer Reports You are not alone if your automobile seems to be burning oil and you frequently need to top off the oil.

The Porsche Panamera and Cayenne, the Audi A3, A4, A5, A6, Q5, and S4 are among the worst. The BMW 5, 6, and 7 Series and X5 are among the worst.

BMW automobiles require frequent oil changes (10,000 miles). As a result, they could use up some engine oil, necessitating an oil top-up in between maintenance. All engines need oil to adequately lubricate the cylinder walls, pistons, piston rings, valves, and turbocharger, therefore oil use is common (s). Under specific driving circumstances, BMW engines (apart from BMW M) may need up to 1 quart of engine oil every 750 miles. In contrast, the more powerful BMW M engines can need up to 2.5 quarts of engine oil per 1,000 miles depending on the driving conditions.

It is crucial to remember that an engine that uses oil within specifications is not necessarily experiencing excessive engine wear. However, our dealer network will be able to offer a timely diagnosis and remedy if a customer encounters a circumstance where there is actually excessive engine oil consumption.

I should have read the instructions first, haha! What’s fascinating is that certain automobiles’ oil may be more heavily diluted, indicating levels that aren’t moving, compared to others, where levels are changing and the dilution is minimal or nonexistent.

Your engine using oil is common. The amount of oil consumed is influenced by the oil’s quality and viscosity, the engine’s operating speed, the environment, the road, as well as the lubricant’s degree of dilution and oxidation.

Even after 600 miles (or 1000 km) or more, the engine oil measurement may not indicate any decline in oil level at all if the car is driven frequently on short trips and uses a typical amount of oil. This is due to the oil gradually absorbing gasoline or moisture, which gives the impression that the level has remained constant.

When a car is driven at a fast pace, such as on an expressway, the diluting substances evaporate off, giving the impression that the oil is being used excessively.

The intervals between oil changes should be longer if you frequently drive in dusty, muggy, or hot weather.

The rate of oil consumption will depend on driving conditions, thus it is important to check the oil more frequently if the vehicle is being driven quickly, the weather is warm, and the load is heavy.

Oil is required by the engine of your car to lubricate and cool all of its moving parts.

Therefore, it is important to frequently check the engine oil and maintain the proper level.

If the oil pressure warning light illuminates and the engine speed is higher than idle, major engine damage may be in progress.

I just joined the forum. I recently purchased my first Porsche, a 2020 or 2021 Cayman S (I’m not sure when I’ll get it yet).

As I normally do before purchasing a new vehicle, I looked online and in forums to see what frequent issues particular models of vehicles had.

I haven’t found anything that would prevent me from purchasing this automobile, including information about poor oil usage.

In the past, I owned two VAGs. 2018 Audi RS3 and a 2011 Polo GTI. They each drank a lot of oil. Every two to three months on average, the oil tank was empty.

I made the decision to stop buying VAG vehicles. Why then did I purchase the Porsche? Because VAG hasn’t modified their engines yet, as far as I’m aware (just read a week ago that the new Cayenne GTS will use the engine of the RSQ8). So I made the decision to buy one quickly before they would.

The salesperson didn’t tell me that Porsche engines are known to consume oil until after I had already purchased the car. I feel as like I’m in a nightmare:(

In one of the forums, I read that several owners claimed their cars didn’t use any oil in between repairs. My issue is that I read the same in both the Audi and the polo.

Why does an engine burn more oil than usual?

Wear-and-tear parts are frequently the cause of burning oil. Your car may burn oil as a result of worn piston rings or valve seals, for instance. Piston rings and valve seals both function to prevent engine oil from entering the combustion chamber.

Porsche uses flat engines; why?

The air-cooled flat engine is the best option for sports cars since it is flat, lightweight, and allows for exceptionally low designs because the cylinders are lying flat. Because of the lowered center of gravity, it is possible to drive in a sportier, more dynamic manner throughout the entire driving maneuver. Because the flat engine’s weight sits on the drive axle when mounted at the back, as it is in Porsche cars, traction is enhanced. Drivers of Beetle and Porsche concurred that a car with a rear-mounted engine was by far the greatest option for winter driving conditions prior to the advent of all-wheel drive automobiles. The contrary is also true: A rear-mounted engine’s weight enables more braking force to be applied to the rear wheels during braking.

The flat engine, especially the six-cylinder version, is exceptionally smooth to operate and has no free moments or forces. Because of the perfect balance of the crank mechanism, short-stroke sports engines may travel at high speeds without experiencing undue strain.

The Porsche six-cylinder flat engines’ tendency to use less fuel as engine power rises is one of their most distinguishing characteristics. The flat engine’s design idea is around a consistent lightweight build, a low center of gravity, exceptional revving prowess, and a high specific output due to favourable charge cycles. All 911 engines must be both sporty and practical for daily use.

In general, a flat engine requires more work to produce than an in-line engine since it requires more parts. Two banks of cylinders, a valve train, cooling, and/or injection are required for the flat engine. Because the individual cylinders of a flat engine are spaced far away from one another, they can benefit from a direct flow of cooling air, making this engine a particularly strong option for air cooling. The four-valve technique is principally responsible for the 911 flat engines being water-cooled since the 996 model series. To reduce fuel consumption and exhaust pollutants while also improving performance, four valves are necessary.

But only lovers of water-cooled flat engines will find this interesting. There isn’t a club by that name yet, but when these engines stop being the newest technology and enter the annals of history, there will undoubtedly be one.

Is it bad to operate an oil-burning vehicle?

When defective engine components allow oil to flow into the combustion chamber, oil burning occurs. If your engine only burns little amounts of fuel, blue-tinted smoke coming from your exhaust could be a sign of this problem but may not always be noticeable. While it’s common for certain automobiles to burn more oil than others, if you notice a continuous low level, it’s advisable to get your car serviced as soon as you can.

Too much oil loss can cause major engine damage and costly repairs, especially in older vehicles with odometer readings of 100,000 miles or more. However, automobiles with fewer than 50,000 miles on the odometer should normally only need a quart more oil between changes.

As of model year 1970, Porsche’s new entry-level vehicle was the 914, which was jointly developed by Porsche and Volkswagen.

The mid-engine Sports Car with two seats was also known as the “VW Porsche.” The very long wheelbase compared to the length of the car, the small overhangs, the removable glass fiber reinforced plastic roof center panel, and the wide safety bar were all notable design elements. Additionally, the 914 had pop-up headlights.

The 914 had two engines available at the time of its debut. Volkswagen 914: 1.7-liter flat-four engine with 80 horsepower 914/6: 110-horsepower 2.0-liter flat-six engine from the Porsche 911 T Following this came a 2.0-liter four-cylinder engine in model year 1973 that had 100 horsepower and a 1.8-liter four-cylinder engine in model year 1974 that had 85 horsepower.

The ignition lock was on the right in the four-cylinder variants. Four wheel nuts were used to mount the 914’s wheels. The Osnabruck body manufacturer Karmann created the standard 914 model (914/4) for the market.
