Bought a E85 test tube tester recently to check out the consistency of a few local Eflex servo's. Both came up pretty close one 73 the other 76. When doing the test on these, it only took a few mins for everything to settle. However, when I did a test of some drum E85 I just bought, after 15mins it still looked like this
Does drum E85 have to sit longer than pump with the test tube test? Or have I pretty much got E100?? lol
