What oil temp is when 2023 x5 40i is warmed up. I want to do pills but don’t know what the appropriate oil temp is.

[eelnoraa]

Oil temp range is large. Consider warm enough to pushing the car, I would say 200F. Under heavy driving, 250+F ks entirely possible. Typical would be somewhere between 220F-230F of you drive normally on street and highway

[azj123]

I was mainly thinking what is the minimum temp recommended to drive it hard, like should I wait till it’s normal operating temp to push it?

Without knowing an exact temperature...the owners manual does give a recommendation as to how to drive depending on what the oil temp gauge reveals.

I would think the unwritten message is...don't drive hard until the engine has come up to normal operating temps. And the manual says where the pointer is when that temp is achieved.

yes, definitely wait for normal operation temp. There are many other downside of pushing cold engine. You can see oil temp in sport gauge. It take good 15-20 minutes of normal driving to get there.

Think this, the turbo will spin at 100K RPM when you push it. The bearing is hydraulic, meaning thin layer of oil. You oil to have the correct viscosity, so it get there and provide lubrication. Same for other bearing, such as rod bearing, crank main bearing, cam bearing ... It is exposure related as well. If you push it cold once or twice, it is not the end of the world, if you do it often and long, say cold car and starting doing track lap, sure shorten life

This gauge is coolant temp for most BMW, including G05. Coolant temp does NOT represent oil temp at all. There are only a few specific BMW model that show oil temp on cluster instrument

I know in sport mode, the temperature gauge is oil temperature per the user's manual, but I was under the impression that it always shows oil temperature as that reacts faster than the coolant temperature in an engine. The manual just says engine temperature, except in sport mode where it specifically says it's oil temperature, not coolant.

[eelnoraa]

In 45e, the temp gauge in instrument cluster is 100% coolant even in sport mode. Please compare instrument gauge vs sport gate temp. When temp gauge on instrument cluster reach middle, oil temp in sport screen is no where near 200F.

Coolant take 5 minute for less to read "mid" point even in cold winter days. This is because thermostat is working, by passing coolant loop to radiator. The amount of coolant inside engine block is small, gets warmup quickly. Oil is entire different story, you cannot by pass oil loop. The entire 7 quad needs to get to operation temp, circulating engine block and head. This also mean the engine block is up to operation temp. We are talking about 500lb of stuffs (engine + oil) here. It will take sometime.

Not quite the same. Qsilver7's said "engine temperature". Your's has "Engine Oil Temperature". Now the icon on both are the same, it looks like coolant icon tho. The oil temp icon should look like the attache picture. BTW, this part of gauge does NOT exist in PHEV. this corner is the HVB level even in sport mode. the only temp reading in instrument cluster is the bar at the mid part, slightly off to the right side (attached picture)

It is very easy to tell if it is oil or coolant. If it take 2-5min to get to middle, it is definitely coolant. Oil cannot get there that fast. If take 15-20min, and gauge slowly ramp up. It is oil. I know X5M has oil temp there, but the icon is different. I don't have 40i, probably I can check coworker's car if I get a chance to drive it for 10 minutes.

OK, I also found picture of my 45e, sport mode, instrument cluster and sport display in the same picture, clearly show instrument at mid level, oil at ~165F. Typical oil temp should at the middle of the sport display, which is 220F

[jad03060]

The attachment is from the 50e user's manual...the 45e's manual says the same thing. Note that there's a thermostat on the oil cooler, so the volume of oil is limited until it warms up, letting the oil warm up fairly fast, maybe close to in lock step with the coolant or close.

Oil temp changes significantly slower than coolant.

Sorry about that…I’m just now able to see the icon in the screen capture of the PDF owners manual I got that info from. I was on my work CPU when I uploaded the images and it was too small to see. I’m now on my tablet at home…so I can expand the pic to see that the icon is the coolant icon which has a temp gauge rising out of wavy lines. The oil gauge icon is a thermostat rising out of an oil tin…which is what the gauge icon is on my f06 & f15…it appears BMW has gone back to using the coolant icon on that side of the instrument cluster like the old E chassis models.

Having the oil temp gauge in the sport display is a nice feature, though. I give that two thumbs up…at least you all aren’t stuck with one or the other. If you want to know your oil temp….just pull up the sport display…sweet.

Good found. Beside the icon, the scale also can indicate oil, 140F-350F-360F, this is definitely oil temp range. Water cannot be at this temp.

I just checked my cars

E39 coolant
E46 coolant
E82 oil
E61 535xi (not mine, just doing maintenance with a friend), none, no temp gauge at all, it is MPG gauge there, WTF

It seem all E series non turbo has coolant. Some early E series with N54 has none. The later E series has oil. I don't have any F series car nor much experience with them

My F11 (530d) displayed oil temperature.

Good observation on the turbo/non-turbo BMWs in the switch from E to F chassis.

The e61 was produced during the era where BMW changed the instrument cluster design from having the four gauge rings down to only two gauge rings...so the oil/coolant temp gauge had to go away...and the moved the fuel gauge into the speedometer gauge as a meter within the speedometer ring.

I'm glad they brought back the four rings prior to moving on to the all digital displays that have everything but the kitchen sink.

I think this BMW mistake of removing temp gauge only exist in E9x and E6x. Toward end of 2000s, they realized this mistake. Even on the two "circle" cluster design, they replaced MPG with oil temp, like in E8x (1 series).

Honestly, if I have to choose between coolant or oil, I think for general public, coolant is a lot more meaningful. Coolant temp will be the first indication of overheating and cause catastrophic issue, long before oil temp can cause issue. And BMW cooling system will fail at various level at 60-80k miles.

Oil temp is more for auto sport, where the car get stress at redline for long duration. I would say even drag racing or autox, the stress is too short to create oil temp issue, it needs to be track events. For people who stress car this way, they all know better how long to warm up before going at it. People who warm up car for 5 min, see coolant gauge reaches middle, and start pushing the car, maybe they need a bit more experience in car and performance driving before doing so.

I went to death valley and ambient was around 130F. Oil reached 280+ while climbing a mild hill and I felt the engine misfiring. No warnings or light but it was enough to have me check the oil temp. Quickly pulled to the side and idled for 10 minutes, it was back to 230-ish. So in my experience, 280 is a no go.

PS. X5's ambient temp sensor tops out at 122F. That's 50.0 in Celsius.

I don't think high oil temp will cost misfire, I don't see how they are connected. What can happen is at high oil temp, BMW ECU will lower boost, so the car will fill less powerful. And 280F, it is definitely on the high side, but I am not sure it is out of operation range.

Assuming that one is using BMW recommended engine oil, oil sump temps of 300º F transiently is not a problem. The flash point of the LL-01 5/30 oil is ~450º F. Change the oil every 5K miles.
