Something for our fellow gearheads. Older turbochargers had their own oil chamber and oil pump. These had their benefits, because they’re now integrated into the engine’s oil system. As a result, contaminated oil from a damaged engine also damages the turbo directly.

Bad fuel is sometimes the culprit. Uncombusted particles can break pieces off the blades, damage the nozzles and/or create an imbalance that will wear out your bearings faster. Thankfully fuel quality is better now, so that’s nice. The old days weren’t always so good…
