Why check the motor oil level in my BMW 840i?

Engine oil is a lubricant for the moving parts in your engine. If your oil reservoir is low or empty, these parts can grind together, generate excess heat, and eventually lead to BMW 840i engine failure. That’s why you should check your oil and get it changed regularly.

Can I change my BMW 840i oil at home?

First off, changing your own oil isn’t as easy as you’d think. You’ll have to buy special tools and figure out a way to recycle the old oil properly. Getting a professional oil change reduces the risk of something going wrong during the service, but also with your vehicle down the road.

Why is my BMW 840i spewing blue or gray exhaust smoke?

Why is the oil light on in my BMW 840i?

Your BMW 840i oil change reminder light may come on if you're overdue for an oil change. The oil pressure light will typically come on if the oil level in the engine is too low, the oil pump is failing, you have a clogged oil filter, or there's a faulty oil pressure sensor.

Do I need to change my 840i's oil filter when I get an oil change?
