Normal oil pressure can vary from 30 to 70 psi depending on the type of semi you drive. If your rig has low oil pressure, there could be a problem. Anything below 20 psi on a truck that has been running for at least 20 to 30 minutes is considered to have low oil pressure. Keep reading to learn what can cause low oil pressure and how to fix it. When you need semi truck maintenance or repairs due to low oil pressure in Anaheim, CA, or the surrounding towns, contact Orange County Fleet Services for unbeatable service. Not Enough Oil The most common reason for a low oil pressure reading is if there simply isn’t enough oil. This can happen even you’ve recently had the oil filled or changed. Check your oil level to make sure it’s above the minimum line. If not, add oil and look for any signs of oil spots or leaks under your truck. Other reasons for low oil could be due to a leaking seal or worn-out piston rings. This is more common with older trucks. Contaminated Engine Oil or Filter Contaminated oil could be caused by a leak, or if fuel, coolant, or water has mixed with the engine. To solve the issue, the leak will need to be found and repaired by a mechanic. Then the oil reservoir will need to be completely drained and replaced with fresh oil. We also recommend replacing the filter in case it is clogged, which can also contribute to low oil pressure.
