What does low engine oil pressure mean?
2 Answers
Low engine oil pressure refers to insufficient gasoline or oil pressure. If it's insufficient gasoline pressure, it may be caused by a malfunctioning fuel pump. If it's insufficient oil pressure, it may be due to a lack of oil in the engine or a faulty oil pump. Gasoline is a volatile, flammable hydrocarbon mixture liquid obtained from petroleum through distillation or cracking processes, used as fuel. Different octane ratings represent varying fuel anti-knock properties, with higher octane numbers indicating better anti-knock performance. Engine oil consists of base oil and additives, where the base oil is the main component of lubricants, determining their fundamental properties. Its functions include: 1. Lubrication and wear reduction; 2. Auxiliary cooling; 3. Sealing and leak prevention; 4. Rust and corrosion protection; 5. Shock absorption.
Recently encountered low oil pressure, it's really urgent to deal with. My car also had this problem before - as soon as the warning light came on, I immediately pulled over and shut off the engine. Talking with the mechanic revealed that oil pump wear or filter screen clogging could prevent oil pressure from building up. Another hidden killer is excessive bearing clearance, which older cars are particularly prone to. A fellow car enthusiast thought he could keep driving with the warning light on, only to end up with cylinder scoring that cost over 8,000 yuan to repair. Remember that red oil can warning light on the dashboard is no joke - if you shut down immediately when it first comes on, you might still save it with a tow, but forcing it will mean waiting for an engine replacement. Now during every maintenance I make sure the filter gets replaced - small savings can lead to big troubles.
