How long until engine is at proper operating temperature?
Guys, how long does it usually take to get your cars engine up to normal temperature? So you can unleash the beast?
I have a 128i and no temp gauge, so it sucks. All I do is a little suburban/highway driving to/from work, usually 20 minutes each way. |

Is that just for the 128? The 135 takes ages to heat up - like 15mins.

Lester, how do you know the 128i is up to temp in 2~3 minutes?
Not liking the absence of a temp gauge on my 128i, I asked my dealer's service manager. He said that BMW's official word to them was that the 128i motor warmed up very quickly and could be revved without concern after 45 seconds to 1 minute. Personally, I give mine at least 3~4 minutes before exceeding 3,000 rpm - more in very cold ambient temps. Tom |

There are many variable of course - such as ambient outside temperature etc. But most normal modern engines are required to warm up quicky to meet emission standards. It does not take long, expecially if you are driving even under moderate load for the engine to reach an efficient operating temp. Two to three minutes is all it should take.

The water is up to temp after a few minutes in the summer time. |

I don't think the oil gauge on the 135i is buffered as it moves around a lot depending on how you drive . But it does it take a while for the oil temp to reach the normal operating temps, so I shouldn't take that and I can drive normally after 3-4 minutes?

I don't think it's overly buffered, just delayed on cold starts. |

I'm not really sure if it's about the engine needing to be warmed up that long, or just a function of the sensor they're getting the reading from. I've read that the oil level sensor determines the level based on how quickly the oil changes temperature. Checking it takes several minutes sometimes. I'm thinking the car does an oil level check on every cold start, and maybe the sensor doesn't start outputting temperature readings until it's finished the process. That's just a theory though. What I do know is that I've had a lot of cars over the years, and I've NEVER seen one that takes even close to this long for the oil to actually come up to temp, so I have to believe we're not getting a real reading for the first several minutes of operation, for whatever reason. |

Personally, if you're only waiting a few minutes, especially just for the coolant to warm, you're doing it wrong. My M Coupe takes longer than the 135i to warm, and it makes sense that the 128i, without turbos, would also take longer than a 135i to warm. Waiting for the engine oil, and transmission oil to get to operating temperature will ensure the longevity of your engine, hammering it before this occurs certainly increases the odds of early problems. If it's a lease, carry on...

So on the 135i, is there any official information on how exactly should you drive before the engine is warm? An amount of RPM you should stay under?

Took mine out for a good run today, and it took just over 15 mins to get to 120 celcius. I dont go over 3000 rpm until the temp gauge is in the middle, then its fun time!
