How long should I warm up my mercedes?

Question

It is a 03 Mercedes E500

Answer 1

2 minutes is good for warm weather....5 for cold.

Answer 2

I have always given the car or truck time to get the oil flowing and the parts lubricated. Somewhere between 30 secs to a minute. Once I start the engine, then I put on the seat belt and adjust the volume on the radio, then you are ready to go. I also, try and drive a little easier during the first 3 or 4 miles giving all the parts time to warm up to operating temp. Then it is to just drive normal. This has worked for me many years.

Answer 3

I agree with fordman and gave him a point. I start my diesel the first thing THEN I do the seat belt thing, arrange anything I put on the front seat and figure my schedule. Then after noting my oil pressure being up I drive away. By the time I'm out of my complex it's plenty warm. I do not run it to the red line until the temp comes off the peg tho'.

Answer 4

Two things, the first is that the diesel is very efficient. When Rudolph Diesel designed his engine he didn't include a cooling system, he didn't think it would be necessary. Second, maybe you have a failed thermostat. My f-250 diesel needs to run with a coolant temperature of 195F or it doesn't run right, to achieve that it has a thermostat that stops coolant from reaching the radiator until the temperature rises and the thermostat opens. Iam having exactly this problem right now, I'm changing the fuel filter, air filter and thermostat tomorrow.

Answer 5

My trusted Mercedes mechanic says there's no need to warm up at all in warm weather. If it's really cold, maybe 30 seconds, and then drive slowly for another 30 seconds before going full speed.

Answer 6

Unless your owner's manual specifically identifies a warm up as normal operating procedure, a car does not need to be warmed up.

Most vehicles operate just fine without a warm up and in fact, the vehicle will consume more fuel because of the warm up.

To warm up a vehicle, drive the first block or two slowly, then proceed as usual. This way, the engine and drivetrain warms up at the same time.

Answer 7

Hi Andrew
If you intend on keeping the car for a long time, you'd do well to allow the vehicle to warm up properly, even if it means burning a little gas,,,,here's why.
On a cold morning, your car has been sitting for 8 - 10 hours overnight. ALL of the oil is sitting in the oil pan, NOT in the engine. When you start the engine on a cold morning, you are turning METAL against METAL for a number of seconds until the oil warms up enough to lubricate all of the internals of the engine. If you just start the engine and go, this is even WORSE as you will have metal to metal while under load, until the oil is sufficiently warm enough to lubricate the complete engine. Any time you are turning metal to metal, you are accelerating the wear on the engine. I allow both of my Toyotas and my Mitsubishi time to get to operating temperature on cold mornings. All three of these cars have in excess of 200K miles on them and I fully expect them to get to 500K using this procedure. Your merc should EASILY get to 500- 600 K using this procedure along with proper car care.
Also note. If your winters are real cold, use a 5-30 oil in the winter time. The 5- 30 oil will warm quickly and coat engine parts faster than a 10-40 oil.
Hope this helps.

Answer 8

There's absolutely no need for an extensive warm up. just drive moderately for the first mile or two.

Answer 9

Long enough 'till it shifts properly into third. Ive had issues that it would neveer shift into third without having it heat up all the way. get it up to a little after the 1st bar.

Answer 10

you really should warm up your mercedes 3-5 mins,
this allows your engine and transmission to run smoother
