Product Information

The Merchant Automotive Oil Syphon Pump is designed to work in concert with the Merchant Automotive Fluid Analysis and Coolant Analysis kits to make it easier to draw a sample without draining. Using the Syphon Pump and included polyurethane tubing you can draw a sample from a dipstick tube, fill plug opening or coolant reservoir cap. Lubricating fluids and coolant are literally the lifeblood of any engine powered machine with engines, transmissions, gearboxes, transfer cases, differentials, hydraulic systems and more relying on proper lubrication and cooling to reach MAximum service life. The MA Replacement Syphon Pump tubing kits include 10-feet of chemical resistant 1/4-inch polyurethane tubing and 10-feet of chemical resistant 3/16-inch polyurethane tubing which is enough for several samples as the tubing can be cut to length.

NOTE: For the most accurate test results and to avoid cross contamination from previous fluid sample draws, a new length of tubing should be used for each sample draw. The poly tubing can be cut with a razor blade or tubing cutter, but be sure not to crush, pinch or kink the tubing when cutting or using it as that could cause a poor seal and make it difficult to draw a sample.

While changing fluids at the general recommended service intervals will work for most applications, it can yield waste, additional expense and added load on the environment and natural resources in the case of replacing expensive oils and fluids before for the service life of the oil or fluid has reached its course. On the other hand waiting too long to change the oil, fluid or coolant can lead to extensive damage and very costly repairs once the protective qualities of the fluid break down and are no longer able to protect, lubricate and cool the moving parts within your engine, transmission, gearbox, transfer case, differential or hydraulic system. With proper fluid analysis it is easier to spot and isolate problems while they are small and less costly to repair.

Following the old-school recommendation of changing the oil and filter every 3,000 miles is a perfect example of premature fluid replacement in most cases. The 3,000 mile oil change requirement myth that your grandpa handed down to your father was developed decades ago largely as an incentive by oil companies and lube shops to sell more oil and service. This may have been a good general rule decades ago when lesser quality oils and simpler component designs were common, but with modern oils and lubricants (especially high performance synthetic versions) extended drain/change intervals can exceed 10,000 miles for modern highly engineered and refined engines and much longer for transmission and gear oils that do not have combustion byproducts to contend with.

But how can we know if we are changing our fluids too early and wasting money and resources or too late and hurting our vehicles? This is where precision fluid analysis comes into play. Merchant Automotive has teamed with the experts at Apex Oil Lab and their state-of-the-art testing facility to offer scientific fluid testing, evaluation and diagnosis with specific attention to automotive lubrication and cooling parameters that is typically reserved for large scale fleet operators, now available for individual customers at a very reasonable price.

Lab testing measures up to 32 different elements to determine wear metals that are suspended in the fluid as well as various contaminants, additives, fuel dilution and more to determine the internal health of the engine, transmission, gearbox, transfer case, differential, hydraulic system or coolant system that the fluid is sampled from. Detailed analysis can help to show problems as they initially develop and can be corrected rather than once they become catastrophic. The analysis can also help you determine the best maintenance interval for your particular vehicle and driving habits allowing you to MAximize the service life of your fluids along with your vehicle. Test results are presented in an easy to read and understand format that clearly outlines the results along with warnings for elevated or potentially dangerous readings that need to be addressed.

One kit is required for each fluid sample, so order a few to be used at a later date or to test multiple fluids within your vehicle at one time.


This replacement tubing kit is for the Merchant Automotive Syphon Pump. The 1/4-inch tubing is best for most fluids while the 3/16-inch tubing may be needed for vehicles with small dipstick tube diameters. Both tubing sizes work with the MA Syphon Pump.

The Merchant Automotive Oil Syphon Pump and tubing can literally be used on any car, truck, SUV, CUV, tractor, motorcycle, ATV, UTV, generator or whatever other vehicle or equipment you own that relies on oil or fluid for lubrication and cooling. Engine oil, transmission fluid, gear oil, hydraulic oil and even engine coolant can be drawn and tested by our partners at Apex Oil Lab.

Can I use the Oil Syphon Pump for other automotive fluids, or is it just for oil?

Despite the name, the Merchant Automotive Oil Syphon Pump can be used to draw samples from all automotive fluids for the purpose of testing and analysis. Note that Apex Oil Lab does not test brake fluid or power steering fluid.

Will USPS mail my sample since it contains oil?

In our experience yes, the USPS will handle mailing oil samples. Please make sure that both the sample bottle and shipping container are both securely closed, and that the information form is inside the shipping container with the sample bottle.

How do I get my analysis results?

The fluid analysis results will be emailed to the email address you provide on the enclosed oil analysis form.

How long does the analysis take?

Oil test results are typically given within onebusiness day after receiving the sample at the lab. Coolant test results can take up to two weeks depending on when the sample is received in relation to the lab's coolant testing cycle. Of course we cannot control how long it takes for the sample to be delivered to the lab, but we are confident that the lab will complete the testing and provide results very quickly (typically the same day if the oil sample is received by 11:00 EST) once they receive the sample.

Can I test both my engine oil and transmission fluid with the same test kit?

While you can send in multiple samples at a given time from the same vehicle, each sample requires its own container. Mixing the samples will not yield usable results for either component.
