Engine Compression Cylinder Pressure 0 300PSI Review

This is a great product for the money and comes in a nice case. It didn't have the right mounts for my intended use, but my cars are a bit odd. I kept the product anyway because I may use it one day. I gave it a 4/5 for accuracy because the handy quick release makes me question the accuracy.

Unfortunately due to the low price I should have known better but I figured the compression tester isn't that much so maybe that's ok. mine doesn't hold the pressure, the gasket material is very weak and the pressure escapes so you can't get an accurate reading. I only test jet ski compression from 75 to 130 pounds. it's better to seal them anyway, no luck, next time I'll buy a much more expensive brand

Tested 4 cylinders and used screw in adapters, did compression on all 4 cylinders showed 75lb per cylinder then used a rubber adapter and tried each cylinder and got a reading of hundred pounds per cylinder. You should have no difference between screw adapters and rubber adapters. Very confused right? I would go with another child that doesn't seem to work or doesn't work at all. I would not recommend this product

I bought this product to do a compression test on my 90hp Yamaha outboard. The first reading was 70psi/50psi/50psi on three cylinders. I ran a second test with similar results (50psi/55psi/50psi). Before taking the boat to the mechanic in the marina, I decided to try it with another tester. I rented one from Autozone and the readings were over 100psi across three cylinders. Save money and time by renting this tool from Autozone (renting is free!) or buy a better tool!

EDIT: Although I was long overdue for the return date because I wasn't at the point where I wanted to check the compression as other reviewers said the customer support was fantastic and They sent me that I need a replacement sensor. So you can make a purchase knowing that if you have any problems, this seller will take care of you. Thanks very much! Original rating: The pressure is wrong. Did the test twice on different days (because I was initially very disappointed with my results). Yes my…

I used this compression gauge on a used dirt bike to see how long the engine had to live. The adapters fit a 250cc Suzuki motorcycle engine. cm and also fit the engine of my B&S lawnmower. All in all it's versatile for what I've needed so far, although I haven't used it on a car engine yet. On the other hand, for the price, this is a very comfortable compression tester. The two adapter thread sizes I've used so far fit well when screwed into the engine's spark plug hole and sealed with an…
