Turbo
![]() Turbo Oil StarvationWhy does oil starvation damage turbos? As turbochargers can operate at over 240,000 rpm and endure temperatures of 950°C, turbo bearings are under great stress. The turbine shaft and bearings rotate in a thin film of oil. If oil is not present at start-up and while the turbo is running, the bearings will fail. Running a turbo without oil for five seconds is as harmful as running an engine without oil for five minutes. While it is important to check the engine oil pressure meets the manufacturer’s specifications, it is even more critical that the oil feed pipes to turbo are clear and clean, so you are certain they can supply oil at the correct pressure. What causes oil starvation?
Extreme heat damage due to lack of oil.
The blue colouring indicates excessive temperatures.
Scoring and discolouration due to insufficient oil.
