Is your blender blade getting more and more difficult to turn? The blade should spin freely when you turn it.

When you give it a spin, it should turn 2-3 revolutions on its own before it comes to a stop; if it stops immediately, it needs to be lubricated! Greatly extend the life of your blender by lubricating it the easy way!

The hard part about lubricating a blender is knowing what type of oil to use, and where exactly to put it! Let’s go through that now.

How to Lubricate a Blender

In this quick guide, I am using a Ninja 900w blender (which I don’t think is made anymore) but the principle is the same for just about any blender you are using.

This is really a great blender, the updated version is the 1000w Ninja which is what I would get if I were buying one now…

Get some olive oil, any type should be fine, the key is that it is food-grade olive oil. After all, this will be touching parts in this blender that may come into contact with your food, so you want to make sure that it is safe to consume in the event that it does make it into your smoothies!

Fill the cup with warm water and 2-3 tablespoons of olive oil. This will be the mixture that you blend. The mixture should go up to the max-fill line.

In addition, pour some of the oil directly onto the spindle shaft of the blender blades. Turn the blades by hand a little bit to work the oil in. Use a bowl or something to catch any excess oil that may drip off.

Pour olive oil around the blade shaft.

This is the critical part: turn the blade mechanism upside down and pour about 1-2 teaspoons of oil in between the cup mount and the spindle, as shown.

Olive oil around the shaft on the motor side is critical. Don't tip it over so that the oil runs out, keep it upside down.

From this point on, keep the bottom portion ‘upside down.’ Don’t turn it over, or all of the oil will leak out!

Keep the blade assembly inverted.

Next, turn the blender upside down, and fit it onto the cup/blade assembly. Turn on the blender for several seconds.

Note: For the Ninja, you press down on the cup (or in this case the blender motor) to activate the motor, so go ahead and do that. For other blenders, you may need to press the buttons. Turn the motor on at the lowest speed setting (e.g. grind).

Place the blender motor onto the cup and blade assembly - upside down so that we don't lose oil!

Verify that oil is not spraying everywhere. As long as you didn’t go overboard on coating everything with oil, it shouldn’t be a problem, especially if you keep everything upside down. 

This helps with the lubrication process, as the oil is forced down into the spindle axle.

Run the blender for 20-30 seconds at a time, 2-3 times. You may even hear the sound of the blender change, as the lubrication kicks in!

Run the blender for 20-30 seconds at a time, several times. You want to work the oil in.

After running the blender for a total of about a minute or so, remove the motor and set it down. Turn the blade by hand – It will be a lot easier to turn!

Check the blade turning assembly. It should spin freely.

If you want to lubricate some more, clean off the excess oil with a paper towel (mine was black!). And repeat the process.

That completes the lubricating process! 

In my experience, I repeat this whenever the blade seems like it is not spinning as freely as it used to, which is usually about every 6 months or so.

If you find that your blade assembly is still not lubricated properly even after repeated attempts, the bearings may be too far gone. In that case, consider buying a new blender blade replacement.

By the way, if your cups break or get worn out, you can get replacement cups pretty reasonably on Amazon.

Cleaning the Blender Gasket – Stops Leaks!

Another thing you should do is clean out the rubber gasket. This will not only stop the blender cup from leaking while blending, it can help to prolong the life of the blender.

The first step is to go-ahead and rinse off the blending/blade assembly with warm soapy water. 

Dry it off, then find a pokey-tool – I found a dental pick to work perfectly. 

Dental pick

Poke the pick between the rim and the threads where the gasket is. Gently pick it out from the side, taking care not to puncture or damage it.

Remove rubber gasket with a dental pick.

Once you get it out far enough, grab it with your fingers and pull it out.

Pull out the rubber gasket from the ninja blender.

Wash the gasket off and also wash the gap where it fits. Get all of the gunk out!

Clean up or replace the rubber gasket in your Ninja Blender.

Once it is all cleaned up, dry off both the gasket and the gap, and press the gasket back in place.
