Anyone ever tested to see how accurate those test-tubes are? I’ve seen them read as high as the low 90’s on some other forums which has made me a little skeptical. Not sure it’s warranted, just asking.

i’d say that the test tube works perfect… had no issues last year… I only used the mobil across from keeler to fill up… travis loves his high priced gauge but a few % -/+ i dont think will cause any issues. My car is getting the proefi ecu as we speak and that comes with its own reader so I will no longer need the test tube…

I use both the test tube and the Zeitronix. The test tube is 100% accurate when used properly. If you don’t fill each fluid to it’s proper line, the reading is going to be a little off. I personally use a syringe to fill it to ensure proper readings.
