A treatment result is recognised as confirmed only where instrumental measurements before and after treatment are available. Measurements are taken with the same instrument, under the same load mode, with running time in between; both values are entered in the protocol.
The list of controlled parameters is grouped by component type: for each parameter the unit, the measuring instrument and the measurement conditions are specified. The report form defines the protocol layout; the filled example shows the content of each field.
Measurement guideline: before applying the compound, take baseline values for the parameters of your component and record the instrument, mode and running time.

One instrument, one duty, one point. The before and after measurements are taken with the same instrument, at the same load and at the same points: otherwise the difference reflects a difference of conditions, not the treatment result.
Running time between measurements. The “after” measurement is taken at the end of the full treatment cycle set by the component's procedure: from 30 to 700 operating hours, or from 1,500 to 4,000 km where the procedure sets mileage. Cycle lengths by component group are given in the pilot treatment timing table.
A second identical unit left untreated. Most cases in this catalogue have no control machine: the treated unit is compared against itself, before and after.
Cylinders of one engine wear differently, so their compression differs and is measured on each cylinder separately. Read the spread between cylinders, not only the average.
Take the first measurement on a decarbonised engine. Only then does it show the real condition rather than compression propped up by carbon: otherwise the gain looks smaller than it is.
Order of preparation:
Compounds and doses for decarbonising — in the procedure for your engine (industrial diesels, diesels under 30 l of oil, petrol engines): the names and doses there are the factory ones.
The form covers the fields most often left blank in the catalogue's reports. The filled example shows the content of each field; the plant in it is a stand-in.

The dosing and operating regime during treatment is set out on the page Guarantees and limits. The full procedure, from preparing the system to the “after” measurements, is in Pilot treatment procedure.
Dose rate, number of stages and intervals are set by the component's procedure: the amount of compound is calculated from the oil or hydraulic fluid volume or from the dose-rate table. All of it is published in full: the procedure for your component — what to add and how many stages, the dose-rate table — the amount of gel by component. The printed instruction comes with the compound; if its revision differs from the page, the printed one prevails.
