How much engine oil pressure is normal?
1, oil pressure is too low, will damage the engine lubrication conditions, causing lubrication, cooling and poor cleaning, will cause parts adhesion, wear and tear. The crankshaft spindle neck and connecting rod journal and bearing clearance is too large, oil viscosity is too low and the filter breakdown will cause oil pressure is too low.
Normal engine oil pressure must be maintained during engine operation. If the pressure is too low, the friction surface due to insufficient lubrication and wear speed; if the pressure is too high, easy to seal, tubing crushed, the engine power consumption. When the car is running, the pressure of the lubricant usually stays at 0.2-0.5mpa. When the engine is idle, the oil pressure shall be no less than 0.1mpa.
2, oil pressure is too high, although not much, but will also destroy the normal lubrication conditions. If the oil viscosity is too large, deterioration of rubber, filter and oil road plug, the adjustment valve improper or can not open, will cause oil pressure is too high
3, oil consumption is too much, the normal engine oil consumption and gasoline ratio is 0.5%-1%, if more than 1% is not normal. The reason for excessive oil consumption is that, in addition to the oil leakage, more oil is burned. The main reason is that the piston and the cylinder wall clearance is too large; piston ring wear or lack of elasticity; the valve guide wear too much damage to the valve stem seal. The SNAP engine super repairing agent can greatly improve the tightness of the piston ring, repair the worn internal parts, and reduce the consumption of the oil.
