How long should I warm up my car before driving?

It largely depends on the age of your car, and whether or not you use fully synthetic oil. Such modern oils are very light (as in, low viscosity) , and do not take long to coat the engine components. My car is already 8 years old, but uses fully synthetic 0W20 oil, and the car manual says to give it ten seconds before driving away. This would be the same for most modern cars with similarly light oils.

Also, next time you turn your ignition to the ‘on’ position, before you start the engine, have a listen for the sounds the car makes. You may be able to hear a slight whirring sound - and this could be the sound of your fuel pump priming. It's important to let this happen before you start the engine. Give the car a few seconds (try counting to 5), before you start the engine. In my previous car, this sound was clearly audible, and when it stopped, I knew the pump was primed and ready to do its job. Getting into the car, and immediately starting the engine is neither good for the engine, nor the fuel pump. It can be a little harder to tell what's going on with keyless entry systems, they vary from car to car, but once the ignition is on, that fuel pump starts priming.

Perhaps most important of all though, is that you should not drive the car hard until the engine reaches operating temperature - most wear occurs when a car is driven too hard when the engine is cold.

So, switch the ignition on and wait maybe 5 seconds max, then start the engine and give it ten seconds. Don't leave the car running long before you pull away, but once you do, drive gently and accelerate smoothly until you see the needle on the temperature gauge rise a bit, and then you can start having a little more fun. This is far better than letting the car run for a minute or two before pulling away, and then flooring it!

If you have an older car, running on mineral, or heavier semi-synthetic oil, you might let the engine idle a little longer, but I still wouldn't wait much more then 30 seconds before driving gently away.

Gazzuzz, good morning. Please my Lexus Es330 is having acceleration issues of recent. Sometimes it moves smoothly and fast, sometimes it lags. I will have to step fully on the gas before my car speeds a little.

My mechanic has changed fuel pump, it stopped for a few weeks then started again. He changed notch sensor, the problem still persists.

Kindly proffer a solution if any please.

Your mechanic needs to change something else. Maybe the tyre, normally factory recommended tyre for the Lexus is Micheline. And it only rolls when you drive or push the car.

He should change the tyres. Ensure you buy Micheline, new, not Belgium.

For the tyres, I doubt. I have been using the car for two years, and this only started recently.

Thanks everyone for your suggestions.

JCFR:
My car Honda Accord 2008 isn't shifting properly especially when am about to go into motion. Highway drive shift smooth but when I slow down and want to accelerate. It fails to move into the next gear and just revs until I pull to N and back to D (not all the time).
I scanned it and it displayed "P0716 Input Shaft (Mainshaft) Speed Sensor (Range/Performance).
What is wrong here?

dicksonadams:
With 150k to 200k you should able to handle gear and labour confidently...

After changing avoid any other transmission fluid apart from Honda genuine transmission fluid.

However if your car is V6 automatic, replacing transmission can be factor in as a routine maintenance item say every 5 years.

Best combo for Honda accord is usual Honda i4 engine and manual transmission, everlasting bulletproof

What's the solution to Camry 2013 transmission shudder that makes it exhibit a brief, intermittent transmission shudder while driving under light loads between 25 and 50 mph? Heard Toyota recalled the vehicles and did software update. How does one fix such car here?

Machini:


I am currently experiencing this with my 2013 Camry too. I pray there's a solution that wouldn't involve replacing the transmission.
