This worked great for testing oil pressure. The manual is a bit ... well, there isn't really a manual per se. You have to infer everything, watch YouTube videos, maybe even read some forums. Here's a couple of things I learned:1) This kit has brass fitting. These are used for 90 degree elbows, extensions, size changes. All of these are NPT threads.2) This kit also has aluminum fittings. These are used to connect between a brass fitting and the car's oil pressure sensor port. Aluminum is softer so I have to assume this will help prevent warping the car's port.3) You can use teflon tape around the NPT brass fittings, but do NOT use teflon tape around the aluminum fitting that you screw into your car. You absolutely do not want to get a piece of teflon into your oil system as it can cause problems.4) Make sure to hold the oil sensor screw threads against the aluminum fitting and make sure the threads match EXACTLY. For example, the Kia Rio I was testing had 1/8-28 BSP threads. You also get a few other common aluminum adapters for various auto manufacturers. Call the dealer service department if one doesn't match and find out what it is. Someone somewhere surely sells an aluminum adapter to match.5) Start screwing the aluminum fitting into your car by HAND. After a few rotations it starts to get too tight to hand turn, so use a wrench to continue until it just starts to get tight. Do not overtighten.6) Start the car and watch the oil pressure for at least 5-10 minutes. Oil pressure psi will be higher when the car first starts and will gradually decrease as the oil warms up. The car I tested started around 60psi and gradually decreased to 26psi. The main thing is you don't want it below 10psi at idle. If it goes below 10psi, you will probably want to turn the car off or else risk ruining the engine. Check the service manual to know your car's exact range.7) When you accelerate the car, the pressure should jump up. For example, the car I tested jumped from 26psi to 60psi.8) You don't want to see needle bouncing all around. That can be a sign of low oil or a pump going bad. It will slightly move with the RPM of the car, but it shouldn't be bouncing everywhere.9) Depending how high up the oil pressure sensor port is located, you may have to drain some oil out of the system before you can unscrew the oil sensor without oil running everywhere. Don't forget to top it back off before testing. After testing, you may then have to drain some oil again before unscrewing the test adapter and putting the oil sensor back in.This tester gave me the peace of mind that the oil pressure in the car I tested is fine, and the oil pressure dashboard light illuminating is most likely due to the wiring harness. It can be safely driven to a mechanic to have the wiring repaired.

Comes with many adapters and two gauges 0-100 psi and 0-400 psi.

Have you noticed how so many billboards are hard to read since designers started creating them on computers? They're pretty, but cluttered and lack contrast in the lettering.This is a good set of gauges, but the dial scale designers went for "cool" instead of "functional." The tick marks are annoying and hard to read at a glance. I have to count 'em up to read the pressure. This review would be five-star if they had designed a good, simple, clean scale.Hoses are good quality and the adapters are well machined.

Let me start by saying I have not actually used this product yet, as the engine I was going to use it on showed enough evidence of oil pump failure without this tool, and has since been removed.That being said, this is a really nice kit and while I hope I don't need to use it any time soon, I'm happy that I now have the tool on hand! The gauges are large and very easy to read, and all of the tubing and fittings seem to be made of fair quality materials for occasional use. This may not be the kit that you want if you're pressure testing engines and transmissions on a daily basis, but for those of use who only get the 'pressure scares' every now and then, I think this is perfect. The blow-molded case is also great and makes storing it on a shelf or in a cabinet easy!Overall, I have had good luck with OTC gauges and tools in the past, and I expect nothing less from this kit! I will update my review should I have any issues down the road.

It’s OTC what’s to say. They do the job well. Would buy again. If you need pressure gauges. Just get these it’s that easy.

I have been working in the automotive world for over 30 years,this OTC kit was replacing a Snap-on tool unit that was way past its prime.I was going to get another Snap-on because of Snap-on quality. I'm glad I didn't.this one is as good and at 1/4 of the priceIt has most of the adapters that you will need, no kit has them all that I have found.when I have a car that I don't have a adapter for I will make one from a old oil presser sender for that vehicle. it is cheaper and quicker than finding a adaptor.the hose is plenty long enough and the gauges are easy to read and are high qualityI would recommend this to any pro or shade tree technicianfew tools score high with me, this one gets a 8 out of 10PROsexcellent easy to read gaugeshigh and low gaugesgood choice of adaptersnice blow mold caselong hoseprice $$$CONscould use 2nd hose for extension when neededhard to get hose into and out of casecould still use more adapters

Can tell right away by the weight of the kit itself that it is high-quality all the pieces are there . no burs on the threads. Excited to be able to give accurate readings for warranty claims

A great set of oil pressure gauges for the home garage or workshop.Ideal for testing engine oil pressure and for transmissions and some hydraulic units .I would like to see improved padded protection around the shrouding.Typical OTC blue and white colour scheme makes these gauges easy to read.The contents comes in a plastic carry case to protect your investment.Airline type fittings make connection to the oil hose easier and prevents kinking.Comes with a variety oil adapter fittings.4.5 stars.
