Remember, the engine won't "blow up." But you'll get a small burnt smell coming from the engine immediately after the high g-force maneuver. And then you'll realize that you have to add a quart of oil every 2000 km of driving when you never had to do that before. Increased oil consumptions among others are signs of a car that was driven aggressively while turning. Sure, drive a BMW 320d or a 320i and nobody will care; adding a liter of motor oil every 2-3000 kilometers isn't that unusual. But let's say there are two 320i vehicles. One is driven by Grandma, and one is driven by Grandson. Both have the same mileage and the same maintenance work done. Grandson drives aggressively through the windy roads in the woods, often taking turns at high speeds and g-forces. Grandma drives more sedately. At 100,000 km, grandson has to put in a liter of motor oil into the engine every 2000 km. At 100,000 km odometer, Grandma doesn't need to add a single liter between oil changes.
The BMW S65 and S85 (the V8 and V10 in the E9X and E60) are actually pretty good cars when it comes to auto crosses and light track duty when it comes to lubrication. But these cars have other problems with rod bearings and valve timing issues. And every S65 and S85 owner who attends autocross or track events probably knows to replace their oil at a frequent interval on these cars. I guess my point is that the other problems of these engines are so significant that the oil starvation issue is overshadowed by the bigger weaknesses. I can't say I'm a big expert on these cars, so I default to our member Convexproblem who probably has owned one. But I was a BMW Car Club officer and I was considering to acquire one of these vehicles, so I did do some homework on them, but never owned one. Nice car though. Really like the V10 soundtrack. Sometimes I think I should've gotten an S85 vehicle.
