EWK Tools Oil Extractor

If you’re planning to do oil changes as a DIY… stay away from EWK Tools.

EWK Tools produces low quality shop tools and products at premium prices. I purchased a 15L oil extractor and it never worked. The most it ever pulled was 4L, and never held vacuum. They tout an 18 month warranty that they never have the intent on honoring. Stay away from their products!

Another option is buy from amazon which at least if something happens you have the support of amazon to make it right.

I'm curious if you had the engine up to operating temp before trying to suction the oil.

When I bought a brake fluid bleeder I tried it out and it would not hold pressure and i was thinking it was junk. Until i looked in the box and saw a tool to tighten down the cap. After cranking down on the cap it held pressure perfectly.

I recently bought a new gas tank for my string trimmer to replace a cracked tank. The new tank was a generic made in china copy off Amazon. My string trimmer is a 4-cycle so the gas cap just has info on using gas only. But the new gas tank must be for a 2-cycle since the cap has both gas and oil symbols. I figure i'll just swap out the caps but to my surprise when I did put my old cap on the new tank gas would leak out the threads. I ended up writing a review and gave it 4 stars noting the gas cap issue. But then I decided to try the old gas cap again and really tighten it down, sure enough the cap did not leak gas anymore. I went and updated my review changing it to 5 stars.

The products I bought worked fine, it was me that wasnt using them right.

Good point, the temperature makes a difference as well.

Just as an FYI, there are a number of good oil suction devices at boat shops. That’s the only way to change oil on many inboard boat engines. I have the 8 liter version of this one.
