Today we are discussing the situation with my engine with our several services all day. The reason is unclear. The reason is definitely not the liners, otherwise they would have given wear and metal particles earlier. Connecting rod liners are not the reason, they just take the blow on themselves, failing. The oil is definitely not to blame, 0-20 retains the oil film, 0-40 in this situation would not help. And yes, we had cases of the same failure of engines with 5-30 and 0-40 oils.
The quality of my oil is good. I pour Wolf 0-20 oil, according to the parameters and tests of the oil, it is better than Acdelco. DFM, not to blame, I was driving 150kmh in Trailer mode, DFM, in these conditions off. There was no dilution of fuel, because I was driving on the highway, and the oil was hot, the fuel in this situation evaporates instantly.
It seems that suddenly, some block gave an error and the oil pump turned off, which, with the engine running at inertia, allowed the connecting rods to work dry, without oil.
What else surprised me. I drove at a temperature of +7C, at this temperature I usually have the radiator curtains always open. When everything happened, I saw that the curtains were closed. Why, it is not clear. Maybe they closed when the engine was turned off, or maybe not.
As one of the versions that the curtains could close due to an error, for example, thereby sharply causing the engine to overheat, which, having received overheating, turned off, turning off the oil pump, and the engine continued to spin without oil inside by inertia. Causing such fatal injuries.
But this is only a hypothesis, since the logs were erased because we were disconnecting the battery.
