BMW N55 Basic Maintenance Question - JB4tech.com

zintapritie2 · 05:44 PM

I have a 2012 BMW 135i, manual transmission. Where I am from, the weather is getting cold. This is my first turbo vehicle, and my factory warranty will be expiring next few months. I am figuring out some stuff....

Starting a vehicle, do I need to warm up my turbo before I take off? Sometimes I am in a rush, so I turn my car on and then take off maybe 10-15 secs later. The manual says that I shouldn't wait and just go take off. I also drive very low rpms about 1 to 1,300 rpm during this stage till my engine warms up before I push it harder, or the oil guage goes to the middle range before I would push it.

Do I need to let my turbo cool off before I turn off my vehicle? I don't drive my car hard, and I know these are watercooled turbo engines. I know the subaru turbo's you should have a turbo-timer and have a cigarette before turning it off, etc. How about BMW N55? Can I just turbo it off right away?

Oil changes, dumb questions, I drove my car for approx. 4-5,000 km since last oil change, how often should I change the engine oil? Is there also turbo oil or just engine oil? I guess, I can look up my manual for this. https://nox.tips/ https://xender.vip https://testmyspeed.onl

Listen to the manual regarding warm up. There is a turbo timer if things are really hot, so no need to let it sit before turning it off. I do oil changes every 5K miles. Turbo oil system is connected to the engine oil system.

I'm in Wisconsin, in winter I try to warm my car for 5 min before taking off and then don't push it hard as the engine continues to warm to operating temp. There are days when I can't warm it for 5 min so I wait for the rpm to fall to normal and then i will drive but I accelerate slower than normal to allow the engine temp to come up. That's just me though.

I'm in Wisconsin as well! Milwaukee for me. Where are you located?

If you have the JB4 it will have a safety that is on by default ( you can turn it off ) that limits your boost until the oil temp is 165*F+
