Why Won’t My Car Start After An Oil Change?

Maintaining your car’s performance and longevity is a top priority for any responsible car owner. Among the various maintenance tasks that should never be over looked, oil change service regularly stands out as one of the most crucial.By adhering to a routine oil change schedule, you can ensure that your prized vehicle continues to run smoothly and efficiently for years to come. Oil changes are a routine maintenance task that many car owners prefer to handle themselves. It’s a fairly straightforward process, but what if you make a mistake? Could a simple car oil change potentially prevent your car from starting?

While it’s unlikely that a minor mistake during an oil change in dubai will render your car completely immobile, there are a few scenarios where issues may arise.

  • Mistakenly Using an Incompatible Engine Oil: This is particularly true for modern engines, which have stringent specifications for the type of oil they should use. The additives in today’s synthetic engine lubricants help to shield the motor from damage at a broad variety of temperatures and pressures. Using the right oil specification in the engine is crucial in preventing long-term harm. The cold oil viscosity is a crucial parameter in the oil specification. When starting an engine from cold, the most damage may be done. The time required for the oil pump to distribute crankcase oil throughout the engine is typically a few seconds. When the oil is cold, its density or thickness determines how rapidly it circulates and how well it covers the engine’s internal surfaces. The engine may refuse to turn over if oil of a higher viscosity than specified is applied. To preserve the engine, the ECU may forbid starting if the oil pressure is too low and the engine oil is cold and thick.
  • Insufficient Oil Added to the Engine:If you don’t put in enough oil when you refill the engine, the oil pressure will be off and the car won’t start.An oil pump, which is often situated in or near the oil sump, circulates engine oil throughout the engine while the vehicle is in motion. The engine control unit (ECU) monitors oil levels and pressure using two distinct sensors.When the oil level sensor in the oil sump detects too low of an oil level, the engine will not start. The oil pressure sensor does the same for the oil being pushed through the engine. The engine control unit (ECU) may prevent harm by turning the engine off if low oil pressure is detected at startup.
  • The Oil Filler Cap Is Missing or Broken:If the oil filler cap is broken, leaking, or improperly reinstalled, the engine may not start after the oil has been changed. When it’s time to change the oil, you’ll need to unscrew the oil filler cap at the top of the engine. When properly reinstalled, it forms a leak-proof seal that allows oil pressure within the cylinder head to rise while the engine operates.Oil filler caps made of plastic are often very durable and may last the lifespan of the engine. Restarting the engine after an oil change with a loose or missing filler cap might result in severe oil loss or low oil pressure. Damage to the alternator, the timing belt, or the ignition coils, all of which are located close to the oil leak, might prohibit the engine from starting.
  • Not Changing the Oil or Using the Correct Oil Filter:Failure to replace a worn oil filter or use an oil filter that is not of the correct standard might prevent the engine from starting. Oil filters come in a variety of shapes and sizes, but each engine requires a particular one. A spin-on filter slots into an oil filter housing, whereas some engines utilize a spin-on filter that attaches to the exterior of the engine near the sump. Selecting an appropriately sized filter during an oil filter change is crucial for stopping leaks and getting the most out of your filtration system. Picking a high-quality oil filter that can trap and hold pollutants is also crucial.If the improper oil filter is used in an engine, oil pressure will decrease dramatically, preventing the engine from functioning as intended.

Don’t put off having an oil change or risk taking your vehicle to a technician who isn’t as qualified as the one you normally use if you want to keep your car operating smoothly all year long. Make sure all connections are snug and everything is back where it belongs before starting the engine for the first time following the oil change to prevent any complications.
