Why won’t my car start after oil change

If you’re wondering why your car won’t start after an oil change, it’s because the engine needs time to fully cool down before being started. If you have a newer vehicle with a computer that controls the timing of ignition, the computer will automatically shut off fuel delivery for five minutes after shutting off the engine. The reason for this is so that any hot oil or debris from the engine doesn’t go into combustion chambers and cause damage. However, we have concluded 5 possible reasons which are causing your engine not start after an oil change.

The following are five possible reasons why your car won’t start after an oil change.

Honda Crv Won’t Start: Possible Reasons And Best Solutions

1. You didn’t tighten the plugs enough

If you don’t give the plugs a good, hard-wrenching when changing oil, they might become loose due to vibrations and general engine movement after starting the vehicle for the first time after the service. This is especially true if you purchase cheap replacement parts or use old stock spares that haven’t been properly tightened by factory service centers. If the plug becomes even slightly loose, it can easily fall out completely while driving down the road. The engine can then suck in air instead of gas and stall out on you right away. To avoid this problem, double-check all connections– not just once but several times–before starting the engine.

2. New oil doesn’t have enough additives for winter weather

When you change your oil at home, you don’t usually use oil that’s specifically designed for cold climates. That’s because most people live in regions where winter temperatures are mild, and the standard stuff works just fine even when it gets colder outside than usual. However, if you drive around in an area where the average annual temperature is below freezing, you should opt for oil with extra anti-freeze so that your car will start right away when the air gets chilly again after summertime. Otherwise, the lack of this additive can be extremely inconvenient during cold seasons when starting problems occur frequently.

3. You filled up with diesel instead of gasoline

This is a common mistake when you fill up your car’s gas tank in a hurry, especially if it is located close to the ground. In most cases, the nozzle will fit into the filler neck with ease even when you put diesel instead of gasoline in there. It isn’t until after you’ve started driving that the misfuelling becomes obvious. To avoid this problem from ever happening again, always check for the fine print on both the pump and inside the vehicle before filling up with gas or diesel. Also, take a look at what your neighbors are putting in their cars so that you don’t make the same mistake twice by accident.

4. You filled up too early

If you change your oil frequently–like every 5k miles or so–you might be tempted to top off the oil tank right away after draining it. It probably isn’t necessary, but if you’re eager to go on a long trip or let your engine run for several hours there’s no harm in doing so. However, if the new oil hasn’t reached maximum capacity after two minutes of driving, it is advisable to pull back over and wait until the level reaches optimal levels before continuing on your way. Otherwise, you will reduce efficiency and save money by wasting fuel by running low on lubricant all the time.

5. The timing is off

If your engine wasn’t started soon enough after an oil change, most likely it won’t start at all due to incorrect positioning of internal components that are reliant on rotation. It is impossible for most people to determine when this part of the service was performed correctly, but mechanics can do it in less than five minutes without opening anything up by using special tools instead of trial and error. If you’re not sure whether or not your timing is off, bring your car back to the mechanic who did the oil change and let them take a look at it. In case they don’t find any problems after checking out your ride, hopefully, they will offer to cover the cost of their mistake since there’s no charge from turning a wrench incorrectly before filling up with oil.

Conclusion

In conclusion, getting an oil change regularly is important for keeping your car running smoothly all year long, so make sure you don’t skip on this necessary maintenance or take your car to an unknown mechanic who may not be as skilled. To avoid any problems with starting the engine after the oil change has been completed, make sure all connections are tight and everything is back where it belongs before turning on the engine for the first time.
