So my F has been very slow to warm up lately, my 25 minute/20 mile commute usually leaves it at only 2 bars and doesn't give me a chance to open it up at all. I assume this is the cold temps (25-45 last few days) and not some issue with the car but it still seems excessively long, anyone else noticing this? Usually takes me about half an hour to get it up to temp.

 

Same here on the cooler days. When it's in the 90s here, it warms up fairly quick.

 

10 qts of oil take a long time to heat up. I put a grill block on mine last night and it seems to help with warmup times

 

Coolant or oil temp?

If coolant temp that seems excessively long and it's possible your thermostat is stuck open.
If oil temp, it's not unusual depending on how you're driving it.

 

Yes oil temp, I tend to keep rpm <2k till i hit 2 bars then <3k till 3 bars. Might have to look into a block heater if they aren't too expensive.

 

I almost made this post last night. Same conditions 30ish degrees and a 25 mile one way commute when I noticed it. I even did a pulls to 5k and still only two bars...

 

Yep. 10qts doesn't even get to temp for me on my way to work either. That's why the F goes under a blanket for the winter--she's not made for cold temps

 

same here. shes my DD and i will drive it carefully. though i do want to get a remote start installed for this reason. i hate the winter...

 

So its purely based on the amount of oil in this engine, nearly every other car I've driven that has an oil temp gauge warmed all the way up in ~10 minutes, even in 0 degree weather.

 

i would def say so

 

I'd say it is pretty normal... in my 10 minute commute, coolant temps go up quickly but the oil temp is still usually at 1 bar when I get to work in the mornings on a cold day.

 

Get an oil pan heater. Something like this: https://www.dieselproducts.com/en/en...s/th250-2.aspx

I live in the great white north and pick up my ISF in a couple days. I fully intend to winter drive it, and the oil pan heater will be one of the first things I buy for it. It's better than a block heater to help solve your problem (although I might use both since it's cold as ***** sometimes here).

Put it on a timer so it comes on a couple hours before you leave for work, and you should be good!

 

Mine is the same way. I usually do about 20 minutes of city driving to work and some mornings I don't even get one bar!

I'm sure our oil coolers aren't helping.

 

That's one of the things I noticed about the F as well, is that it takes a while for it to warm up. My previous C63 that took 9 quarts would warm up after I get off the highway in the morning, on the same commute my F won't hit 3 bars until I'm already pulling into my work garage, or when its colder it won't hit 3 bars at all.

 

Not much you can do about it and one of the main reasons gasoline engines have only held five quarts for fifty years. Any more and the motor just stayed cold. Engine oil coolers just made heating the motor worse. Operators did use engine oil heaters, blankets and other devices. During WWII the germans on the eastern front actually built fires under their tank and air craft engines.

Today it is a little bit better, Synthetic engine oils work well in cold temperatures (Make that cooler temperatures in the forty degree F range, in my opinion) I would not worry about the gauge and if you have two bars, run the hell out of it. Some expert engine people will run a motor to 10,000 RPM after a one minute or less warm up. (Outside air temp is usually 70 degrees or so.)

Basically if you use a little judgement you'll be fine. However, I'd use a good quality engine oil and the expensive stuff is not always the best.
