Why do wolves roll in engine oil on forest roads during early summer?

In Belarus during many years of study on wolves during the early summer (May-June), when I was investigating denning in wolves, I noticed numerically that wolves roll in an engine oil on forest roads once and again. The same red foxes do, sometimes, lynxes do that. Later in July-September wolves almost stop this habit.In Belarus just  early summer is characterized by a horrible outbreak in mosquitos. So, I think that wolves apply engine oil as some kind of anti-mosquito’s repellent.

Interestingly, that the same i.e. usage of engine oil (for instance from a crashed land battleship) against mosquitos was applied by partisans and survivors during the Second World War in Naliboki Forest in Belarus.
