Each oil extractor was assembled according to the manufacturer’s instructions. We then used each extractor to pump 1.0 quart of warmed synthetic oil and timed how long it took to empty its contents. After being filled, each pump was emptied and cleaned according to the manufacturer’s specifications.
Assembly: The first step to using any oil extractor is putting it together. We tested each oil extractor by putting them together properly, determining both difficulty and time elapsed, while using the manufacturer’s instructions if included in our purchase. The oil extractors that were easiest to assemble and put together scored highest in this category.
Speed: When using an oil extractor, you want a quick and easy process to get the job done in no time. By comparing how quickly each product extracted oil during our testing process, we could accurately rank each oil extractor according to speed. The oil extractors that performed the quickest scored highest in this category.
Cleanliness: When handling oils and other liquids in your car, the process should be clean and not require much tidying up afterward. The oil extractors that were easiest to clean up and pour oil out of for proper disposal scored highest in this category during our testing process.
How We Score Products
We want to honestly evaluate and compare each oil extractor and all products in our reviews. To do this, star ratings help us rank and differentiate between the top products on the market. For the oil extractors in this review, we calculated an average of 4.5 out of 5.0 stars.
: A 5.0-star rating is a well above-average score. If the oil extractors in this review exceeded our expectations in at least one testing criterion, you’ll see a 5.0-star rating.
: A 4.0-star rating is an above-average rating. If the oil extractors in this review could have been quicker in the extraction process but still completed the job in a timely manner, you will likely see a 4.0-star rating.
: A 3.0-star rating is an average rating. If the oil extractor posed some difficulty when it came to clean-up, but still had little to no spillage by the time we were done testing, we would give the extractor an average score.
: A 2.0-star rating is a below-average score. If the oil extractor was very hard to clean and caused some spillage, making the entire process more time-consuming and difficult, the oil extractor would receive a lower rating.
: While rarely seen in our reviews, a 1.0-star score is a well below-average rating. If the oil extractor is defective in some way, either during the assembly process or operation, we’d give the extractor a 1.0-star rating.
