When it comes to turbocharged performance, oil quality is everything. Your turbo operates under extreme conditions—spinning at speeds up to 240,000 RPM and enduring temperatures as high as 1,000°C. With these intense demands, the turbo relies on a thin film of oil to keep its bearings lubricated and running smoothly. If that vital oil supply is compromised, disaster is just around the corner.
HOW DOES POOR OILING DESTROY YOUR TURBOCHARGER?
Turbo bearings are designed to operate with a consistent, pressurised oil supply. The moment that supply is restricted—whether due to starvation or contamination—the thin film of oil disappears. Once that happens, metal-on-metal contact occurs, creating excessive clearances and rapid wear. In fact, running a turbo without oil for just five seconds can cause catastrophic damage, leaving you stranded.
Maintaining proper oil pressure is critical. A general rule of thumb is ensuring a minimum of 15 PSI at hot idle. However, it's not just about pressure—your oil feed pipes must be clean and free of debris. A clogged or contaminated oil line can starve the turbo of oil, leading to premature failure. Worse still, dirty oil can scratch and score the bearings, accelerating wear and reducing turbo lifespan.
COMMON CAUSES OF OIL CONTAMINATION & STARVATION
-
Overdue or clogged oil filter – A dirty filter restricts flow and allows contaminants to circulate.
-
Excessive carbon buildup in the engine – Old deposits can contaminate fresh oil, reducing its effectiveness.
-
Faulty oil filter bypass valve – If malfunctioning, it can allow unfiltered oil to flow into the system, carrying debris straight to your turbo.
-
Oil breakdown due to high temperatures or extended service intervals – Over time, oil loses its ability to protect, leading to increased friction and wear.
HOW TO PREVENT TURBO FAILURE FROM OIL ISSUES
At Demon Pro Parts, we know that cheap oil is an expensive mistake when it comes to turbocharged engines. Here’s how to protect your investment:
✔ Use only high-quality oil and a new oil filter—stick to manufacturer specifications to ensure proper lubrication.
✔ Choose the correct oil grade for your engine to maintain the right viscosity and protection levels.
✔ Inspect and clean your oil feed lines before installing a new turbo—carbon deposits, sludge, or debris can restrict flow and cause failure.
✔ Follow regular oil change intervals—old, degraded oil puts your turbo at risk.
Your turbo is only as reliable as the oil that flows through it. Don’t cut corners—choose premium lubricants and filtration, and if you do need a replacement turbo, check out our huge range at Demon Pro Parts to keep your turbo spinning strong.
