Any BMW with AWD, including any “xi”, “xDrive,” or “X-series,” has a front differential that requires fluid much like the rear differential. The standard 75W-90 differential fluid recommended by BMW is used. Along with the BMW fluid, we also offer the excellent LIQUI MOLY 75W-90 gear oil as a substitute.

You can check with Volvo, Toyota, Honda, and other manufacturers, but the majority of them do not mention fluid changes for MT. This is largely because MT, even when using factory fluid, easily lasts 200K miles or more with the same fluid. This (200K miles) is much beyond the threshold where automobile manufacturers care.
The drain plug on many MTs has a magnet to collect metal shavings from friction. Unlike Engine Oil which is contaminated by gasoline combustion by-products, MT fluid is not impacted by gasoline combustion by-products but rather by metal fragments.
It makes sense to change the MT fluid every 50K or so if you value your BMW and want it to last 350–400K. This is what I do, and as far as I can remember, it is not described in any service manual. In a sense, MT fluid maintenance is a “orphan” or “forgotten infant.”
Reasons to Replace BMW Transmission Fluid
In rare cases, BMW Service Advisors or other repair facilities have advised BMW drivers that they shouldn’t change the gearbox fluid in their cars. This, however, is a total fabrication; according to BMW, most of their models should have their transmission fluid replaced every 100,000 miles, and the M models should have their fluid changed even more frequently. The shops that advise against changing the fluid may simply be unfamiliar with BMWs and reluctant to try. No fluid is actually lifetime.
Even more extreme advice has been given by some gurus, who claim that replacing the transmission fluid “simply causes problems” with the car. Maintaining the performance of your BMW requires changing the gearbox fluid. Each BMW benefits from these service plans since they are built with particular maintenance schedules in place to guarantee that the life of your car is extended as much as possible. Transmission fluid is a crucial component for many of your car’s operations, even if it is not frequently needed.
How can the transmission oil of a BMW be checked?
- Prior to checking the level, turn the engine on for a while.

You should change the fluid in most manual transmissions every 30,000 to 60,000 miles, and in most automatic transmissions every 60,000 to 100,000 miles.
What volume of oil can a BMW differential hold?
A new drain stopper and a few fluid bottles are all you need to finish the job. BMW claims that even though the drain/fill plug is made of metal, the Viton-style seal they utilize is only intended for one usage. It will cost you slightly over $5 for the new plug.
BMW sells 500ml fluid bottles, and the differential requires about 1.2-1.2L. You’ll need at least two bottles to fill the diff because the bottles cost about $60 each. Set aside about $200 for the project overall. The additional funds should be used to purchase brake cleaner or rags to mop up the surplus fluid that will leak from the differential.
BMW requires gearbox fluid, right?
You don’t even need to drive your BMW to see these warning signals of transmission trouble. Step outside of your vehicle after starting it. Is it scratchy sounding? Your transmission may be having problems if you hear unexpected noises like grinding, slamming, rumbling, or other odd noises.
Check for any odd scents emanating from the vehicle while you’re out there. Every 30 to 60 thousand miles, your BMW’s gearbox fluid should be changed; if it isn’t, it may begin to smell. The transmission fluid could have a pleasant or burning odor. Your car should be taken in for an inspection if it emits any strange smells.
Does BMW require a replacement of gearbox fluid?
In order to keep your car’s transmission lubricated and friendly, BMW transmission fluid changes are strongly recommended. Your BMW transmission may slip if you don’t frequently check your fluids at least every 30,000 miles or so.
How is gearbox oil checked?
- Your engine must be running and the oil must be heated in order to read the dipstick. To begin, park your car somewhere flat, engage the brake, and let it sit idle until the engine heats up.
- Locate the gear oil dipstick by opening the hood of the car. Typically, this is placed close to the rear of the engine compartment.
- The dipstick should be removed, cleaned with a cloth or towel, and then reinserted. Check the oil once again with the dipstick. The cross-hatch pattern on most dipsticks indicates where the oil level should be. Additionally, you might see hot and cold lines; your oil shouldn’t ever cross the hot line.
- If your oil is getting low, top it off with the recommended amount of gear oil; you might need a long-neck funnel for this.
What happens if you don’t change your gear oil?
Your car’s gear systems frequently make metal-on-metal contact, which generates heat and wear-and-tear. By lowering friction and transporting heat away from them, gear oil contributes to the protection of these moving parts. Changing your car’s gear oil on a regular basis is critical maintenance that will increase its lifespan and save you money on future repairs.
In your car or truck, differentials, transaxles, transfer cases, manual gearboxes, and transmissions all need gear oil as a lubricant. Your transmission runs more smoothly thanks to gear oil. More importantly, it assists in preventing essential internal wear and heat damage in the gear systems of your car.
Important drivetrain components might get scoured, corroded, scratched, and pitted as a result of inadequate lubrication. Your car’s performance may be hampered by this deterioration, which could ultimately require expensive repairs. Motor oil and gear oil are not interchangeable and are not the same thing. For use on gears, gear oil is specially prepared. Motor fluid That’s right, it’s for motors.
Consult the owner’s manual. The specs of a gear system might differ from car to car. It’s vital to use just the gear oil that is advised by the manufacturer of your vehicle because using the incorrect gear oil could lead to poor performance or even damage to internal components.
The most popular gear oils on the market are those with the GL-4 and GL-5 classifications assigned by the American Petroleum Institute based on overall performance. Most automobiles require GL-4 gear oil. GL-5 gear oil may be necessary for heavy-duty or high-performance vehicles like trucks and sports cars.
You run the danger of seriously damaging your car’s transmission and other gear systems if you don’t change your gear oil according to the manufacturer’s recommended timetable. This can necessitate expensive transmission repair and part replacement.
Over time, gear oil deteriorates. Many metal-on-metal contacts are necessary for the operation of manual gearboxes and other gear systems. These moving elements are worn down by natural friction, and microscopic metal particles gradually build up in the gear oil. If your gear oil is not drained and replaced on a regular basis, these variables will gradually reduce the lubricating characteristics of your gear oil, shortening the lifespan of your transmission.
If you drive your car normally, you should have your gear oil changed every 48,000 to 80,000km (30,000 to 50,000 miles) for an automatic gearbox and every 96,000 to 160,000km (60,000 to 100,000 miles) for a manual transmission. For more information, consult your owner’s handbook first. You may need to change your gear oil as frequently as every 24,000 kilometers (km) if you frequently subject your vehicle to harsh circumstances, such as towing or driving through mud.
As you change gears, pay attention to how your transmission feels. Does it thump or slip? Other indications that it’s time to change your gear oil include strange burning smells and whining or grinding noises. Watch out for leaks because they may be a sign of tainted oil. It’s time to change your gear oil if it’s black or grittly. Last but not least, an illuminated “check engine” light on your dashboard is always an indication that anything inside the engine has to be fixed right away.
