FIA warns teams of Australian GP with oil consumption controls

D he tiresome oil consumption issue continues to smolder. The FIA ​​has already tightened the thumbscrews on the manufacturers. From this season onwards, only 0.6 liters of oil may be used per 100 kilometers. Last year the limit was initially 1.2, from Monza to 0.9 liters. The lubricant has recently been specified precisely. This rules out unwanted additives. It is no longer allowed to use two different varieties on one weekend. It is also forbidden to return the gases in the crankcase to the combustion process. In this way, the FIA ​​wants to prevent the manufacturers from using unauthorized oil additives to mobilize extra power during combustion.

Despite the clear limit, there are still major differences in oil consumption. Mercedes and Ferrari are therefore close to the limit of 0.6 liters. Renault and Honda are content with 0.1 liters per 100 kilometers. Because the suspicion is still circulating in the scene that there is trickery with oil consumption, the world association now wants to take harder and more transparent measures for everyone. And that is exactly what could lead to chaos in Melbourne.

Samples with full and empty oil tanks

The FIA ​​is measuring oil consumption this year with a sensor, but it only delivers over long distances the required accuracy. With a race distance of 310 kilometers, a maximum of 1.86 liters of lubricant may be missing after the race compared to the initial state. It becomes more difficult in qualifying when the teams are only 60 to 80 kilometers away. That would mean a maximum permitted oil consumption of 0.36 to 0.48 liters. Small measurement errors could have a big impact.

That is why the FIA ​​will repeatedly take samples of the teams over the season before qualifying. And with archaic methods. The teams have to remove all oil tanks so that they can weigh the technical delegates empty and full. Sounds simple, but it isn't. The cars are equipped with two or three oil tanks. They are often in hard-to-reach places. A check with the subsequent assembly can take a long time. 'We don't let a car on the track before it has been checked,' says FIA circles. If the process takes too long, teams may miss out on training. You cannot refuse because the regulations state that in an emergency, you can call the StewardsHaving to prove the legality of the car.

Mystery of the smoking Ferrari engine solved

Ferrari had an additional problem to solve. During the test drives in Barcelona, ​​the works team and Sauber in particular developed considerable smoke after starting the engine. Obviously, too much oil was burned when the drive unit was cold. Which would have been a problem mainly for Ferrari. Because the amount burned when starting naturally counts towards the total consumption.

The riddle of the smoking Ferrari engines has now been resolved. Obviously there was a lot of bearings in the turbocharger with excessive tolerances. As a result, oil was blown into the engine through the compressor and burned in the process. That is also the reason why the phenomenon was only seen at Ferrari and Sauber. Another batch of bearings is said to have been installed in the turbocharger for HaasF1.

In the gallery we show you once again the spectacular images of the unusual smoke development at Ferrari.
