Clarity in the oil consumption dispute
Nobody tricks with the oil
Finally, there is clarity in the dispute over oil consumption. At the request of Mercedes, the FIA has specified what they mean by the limited to 0.6 liters per 100 kilometers of oil consumption. This includes all the oil, including the one used in the turbocharger.
It was just a suspicion. The smoking Ferrari engines made the competition suspicious. Was everything right there, or did Ferrari find a way around the oil consumption limit of 0.6 liters per 100 kilometers? And if so, how? The engine engineers racked their brains on how to outsmart Article 20 of the Technical Regulations. Until one had the idea, one could press the oil into the combustion chambers via a "leaky" gasket in the turbocharger's supercharger, but not count it for consumption because the turbocharger is by definition not an engine.
On May 14, Mercedes sent a request to the FIA. The engine engineers in Brixworth wanted to know if the oil consumed in the turbocharger counts to 0.6 liters. And if so, would the combined consumption of lubricant in the engine and turbocharger have to be counted towards consumption limits?
The turbocharger is part of the engine
The answer from Charlie Whiting came immediately. In a circular letter to the four engine manufacturers, the FIA race director made it clear that all oils used in the drive unit fall under Article 20. From the point of view of the World Association, the turbocharger is the engine. Accordingly, the oil burned in the internal combustion engine and the turbocharger must be included in the total consumption.
The shot of Mercedes was obviously directed against Ferrari. But he missed his goal. We hear from circles of the FIA that none of the four engine manufacturers have to rebuild their oil system or the turbocharger. If someone had tricked in this area, he would have had to modify his turbocharger with immediate effect. Neither of the controls found a separate oil circuit for the turbocharger. This is the topic of the table. The battery affair, however, is still smoldering. But it should clarify the course of the weekend.
