What does it mean when the oil pressure gauge is maxed out?
1 Answers
The reasons for the oil pressure gauge reaching the maximum include: 1. Insufficient oil storage, leading to no or little oil in the lubrication system, resulting in low oil pressure; 2. Dirty or overly viscous oil preventing the oil pump from effectively drawing in and pumping out oil, causing low or no oil pressure; 3. Oil being too thin or becoming thin due to high engine temperature, leading to leakage through the engine's friction gaps; 4. Oil pipe leakage, damaged oil pump, or excessive wear of its components reducing oil intake and output; 5. Excessive clearance between the crankshaft and bearings causing oil leakage; 6. Malfunction or weakening of the pressure relief valve due to soft or stuck springs or damaged steel balls; 7. Faulty oil pressure sensor, gauge, or electrical circuit.
