***Note: I forgot to mention in the video, as you can see I had a feeling that the oil sensor was NOT reading the oil correctly because it tends to lag behind the acutal measurement. The oil sensor seems to take a reading at certain intervals and then averages it out over time. The issue with this is that you may be burning oil faster than it can read ESPECIALLY if you do SHORT TRIPS. The oil level sensor will never get warmed up enough to actually give a good readout. So if you are leaking oil or burning oil and doing short trips, you could blow your engine easily because the sensor will never have time to do its work. This would cause your engine oil to run very low and eventually something would blow up.

N52s are high revving but not particularly high at 7k rpm? I thought was common for a 2.5l engine. Max power at 6500 rpm so anything after that probably lowers a 0 - 60 time ? I think BMW designed a larger crankcase so they can increase intervals between services, secondly it is possibly a failsafe measure due to these engines consuming oil.

[@vincentcooray9269]

Nice one bro. At last another video. Glad you answered my request. Excellent videos 👍

[@buildanddrive]

Thanks for the motivation. Editing the next one! 🙏

[@chadriddle3517]

1.25 liter low is my guess. I’ve done this with my 07 n52 b30 and if you suck all the oil out of the oil filter housing and let it drain for a long long time mine was roughly 1.25 liters low . Mine also uses oil between changes . It does not smoke and performs well it just uses 1 liter every 2,000-2500 miles which is way to much in my opinion but after years and years of use I’m pretty much use to it . The engine is great otherwise . Well it does have an oil pan gasket leak. So I loose a tiny bit there also. I just been avoiding that job lol . Ty for the bmw content

[@buildanddrive]

1L per 2500 miles is pretty good even with some leaks. But the n52b30 shouldnt burn oil so you're good🙏🏼

[@eriqrosado3337]

I drive an e90 08 328xi here in the states and it’s an n52b30a and the most my cars ever burned up was maybe a lt. but I’m gonna have to pay more attention. But I’ve been trying to figure out away to reto fit the s65 dipstick to ourn52’s

[@buildanddrive]

That's a great idea. I wonder if that would work. Does it share a similar oil pan?

[@eriqrosado3337]

@@buildanddrive that I don’t think so but I wanna say that on the n52 pan there is a spot that is marked for what would look like a dip Stick spot from older bmw engines

[@anantmaher2736]

I have a general question. I have 320d e90. My oil light kept showing, so I had my oil and filter changed as well as putting a new sensor on. Now I don't even see the oil level indicator as option on the bc list anymore?

[@buildanddrive]

Is the sensor plugged in? 😅😅😅 You're gona need to to check what's going on with your oil.

[@Dutch79]

Luckily I have the N52B30. These don't seem to have these high oil consumptions levels. Although mine is from late 2005 and has 320K kms already. 1:3000 for several years now.

[@buildanddrive]

Yes, these engines shouldn't have the same issues

[@hayleythomas2642]

My 07 120i smells funny every now and then but no oil on the ground whatsoever i got it serviced a month ago and only travel 5mins to and from work. My oil light will show every now & then. i’ve bought a new sensor for peace of mind but now it seems common for them to have faults? what would you recommend

[@buildanddrive]

What does it smell like?

[@mobb5014]

These happen to me ima just drain the oil and put new one and see how many liters I was really missing I’m taking the safest route

[@buildanddrive]

Yes, if you don't know your car yet, when you change the oil, measure it out. 👍🏽

[@zionswope3114]

Just did oil change and put 7 quarts and then the next day it reads lower and lower oil as the day goes by I’m sitting at 5 quarts but engine performance is not affected could it just be sensor

[@buildanddrive]

Not sure. Drive it a while and see if the sensor sorts itself out

[@walkeratsea]

Hey man - Good oil test there . I have a 14yr old 320i petrol coupe auto . And I’ve been suspicious of the oil level sensor for some time . Q. When dose the light come on !? I mean how low does the level have to go before it alerts you to top up ? Looks like for your motor . A litre or more . I had a feeling that mine was not running as smoothly as it normally would . More valve noise when cold . I took a chance and added 3 quarters of a litre and it’s back on top form !!!! I mean it made a significant difference . Pretty serious design flaw . It’s a shame as I really like the car and BMWs in general . I’m going on a long trip soon . I’ll be driving for over 9 hrs . Any advice on preparations for this ? Also --- Is there a High level sensor in the sump ??? Or will it just say OK 👍 even if the oil is bursting out of the engine Regards 🙏🏻

[@buildanddrive]

Bring oil in 1L jugs with you. As soon as the yellow oil light comes on, add 1L and drive the car at least 30 minutes before checking the oil again.

[@SebastianTapia-zr7nu]

Hey bro i have a 04 525i The light came on but i thought it was a oil change and i took it to the mechanice and he said it was coming out th drain plug. He said when he drained it. There was 3 to 4 quarts left. I was driving to work with the oil light on for two weeks. Did i mess up my car? Just wondering if it was leaking out drain plug and i was driving car for 2 to 3 weeks. Did i put wear and tear on it or everything should be fine.. mechanic said there was 3 to 4 quarts left and my car takes 6.9

[@buildanddrive]

It's possible. Should have checked the oil and filter for any shinny metals when you changed the oil. Drive the car with fresh oil, if you have no knocking or noises then you dodged a bullet. Always add 1L the moment the light comes on.

[@mollotin3060]

Yeah, just drained oil on my n52b25 and got only 4 liters out. the oil gauge did not even tell me to add anything... lol

[@buildanddrive]

😅😅😅😅😅😅

[@geronimomadmartin3499]

Is there a bypass oil system with an incorporated cooler for beemers? If so it could help increase capacity and possibly the oil longevity.

[@buildanddrive]

There is an oil cooler. It doesn't add much though.

[@BillCipher1337]

i have a N52b30 and the oil level jumps between 1/4 and 3/4 is this normal ?

[@buildanddrive]

No, how often does it jump?

[@sassysai8303]

I’m having the same issue on the e92. I’ve never had any issue before, but today I changed my oil. It said my oil is low and I literally just put in 5 quarts.

[@buildanddrive]

I would drain all the oil and measure exactly 6.5L of oil into the engine if you have the n52 engine. Then drive the car to see if the oil sensor is working correctly. If not... Replace it

[@sassysai8303]

@@buildanddrive thx you. I just learned the xdrive requires 6.9 and I only put 5 quarts

[@buildanddrive]

What year/ model BMW do you have?

[@sassysai8303]

@@buildanddrive I have a 2009 328xi

[@MattyBeanz]

@@sassysai8303problem Is… there could be still 3 quarts (which might be below the MIN). So if you add 5 then u will be over by at a couple quarts! Be careful… I messed up bc I added too much and then the oil pushed thru the seals bc it has nowhere else to go… ultimately leaking into the spark plug/ ignition coils causing misfires and feeling super sluggish… Nevertheless, just wanna give a heads up in case my experience might help someone out!!! So dumb BMW doesn’t have a dipstick!!!! I gotta ask my buddy who’s a BMW mechanic if there’s a reason behind that decision 🤦🏽‍♂️

[@sebaseb6930]

Hello you got Lower consumption oil after rebuilt?

[@buildanddrive]

No, I had several oil leaks that were causing the oil consumption reading to be wrong. I went from 1L/300kms to 1L/1600kms after the rebuild. I could have gotten even better oil consumption numbers if I replaced the pistons with the newer design with the new the oil return holes.

[@sebaseb6930]

@@buildanddrive thanks

[@patriciamorris4698]

Hello. I have a 320 BMW x drive. Only done 12k and over 3 years old. Oil level status is at maximum supposedly according to the beeps I keep receiving. It was serviced by BMW in September 2022 so I know its not the oil. Can anyone help me. It must be a dodgy censor. Thanks. Tricia.

[@buildanddrive]

What's happening exactly? What is beeping? What info is showing up on the dash?

[@Dutch79]

Oil level measurement: if you had idrive, you would get a message that the engine has to warm up fully before the oil level can be measured ;)

[@buildanddrive]

When you check the oil (before its warmed up) it also tells you its not ready to give a measurement.

[@Dashikardashian]

Can I get Idrive on a 2015 bmw?

[@workonesabs]

A colleagues car BMI series 1 , just lost all its oil. Yellow light came on, we stopped and checked oil. Very low. tried to get to garage then red light came on. Told him to stop right now!!! We did. What was left of the oild

[@buildanddrive]

Wow. How did it lose all it's oil???

[@workonesabs]

@@buildanddrive found out today, the turbo feed pipe fell off, or the bolts did. Garage fitted a new turbo last year - looks like they didn't tighten them properly...

[@lifenthefastlane]

Mine is the same way. Says 1 quart low drain out 5 instead of 6 quarts. In US it holds 7 quarts.

[@buildanddrive]

Yes, I'm not sure if this is by design that the oil pan can hold more oil than it should but the part that worries me is how much oil is left when the light comes on.

[@crazyharis]

I have a bmw 630i 2005 n52b30 !! Every month it pups up that i have to fill 1 liter ... i do so... so i think its normal that i have to fill it up .. when i fill it up the massage disepears so my engine consumes oil 😅

[@buildanddrive]

Possible.

[@geronimomadmartin3499]

My 2006 E61 goes through a quart about every 1000 miles, but I never see any smoke from burning oil. Is this normal?

[@buildanddrive]

Normal. 👍🏼

[@buildanddrive]

Is it possibly leaking any oil?

[@geronimomadmartin3499]

@@buildanddrive I've never seen a drop under it. The dealership says that the oil pan is leaking, but if it is I don't know where it's going. Also the valve cover gasket was done recently, so that might be why there's oil residue at the oil pan.

[@buildanddrive]

I'll make a video on every single oil leak on an n52 😂

[@geronimomadmartin3499]

@@buildanddrive I will definitely watch them all.

[@georan4323]

I hate the god damn digital oil reading gauge. It cost me a new valve cover. Apparently, I kept adding oil after they installed a new oil level sensor. It came on first thing when I started the car. And of course..what does the wife do....she adds oil and so did I. Causing it to overflow and blow the oil diaphragm housing that's built into the valve cover. Now, I won't add oil until I have at least driven the car for 45 minutes (this gives me a true reading) I wish BMW would get rid of that feature and go back to a $10 oil stick. Wish I knew of a way to weld an oil stick to my BMW now.

[@buildanddrive]

Dang bro. That sounds rough. Glad it didn't blow the engine!!!

[@leifharaldlongbeardiii861]

hey man how much oil you burning no per km, and you said bmw was telling people that 1l per 700km is ok, i thought it was 1l per 700 miles

Sorry, it's 1L/700 miles is what BMW says. My car is at 1L/1400kms

Dude if you can smell perfume through that non Bacteria Mask you are wearing ,you understand it does not workie Right !?

[@toonmag50]

Haynes manual and my wife's BMW manual states the oil needed is 5W 30. I dislike her BMW e91 , as just looking at it "the wrong way" something goes wrong. Most unreliable plastic box I've ever shared a driveway with. DIY oil change, just "do the maths" 5 litres new oil straight in. Drive a little Top up by one litre and relax. Do not be dependent and or preoccupied with your magic light Check the oil sensor light a couple of days later, following normal use

[@buildanddrive]

my old engine was burning oil 1L/300kms. The oil burned so fast that the light wouldnt come on fast enough, it evenually wore out the piston connecting rods due to lack of lubrication too often. (years of driving like this)
