filled..
5. Once the syringe is full, remove the hose, empty
the syringe into the bottle and seal it as soon as
possible.

3/4 full.
7. Close the bottle by tightly screwing the cap and
check the information on the label.
Method 2: Sampling at the Drainage Point

draining of the oil sump.
1. Read and follow the safety precautions in
Section 3.1.
2. Place a basin under the drain point.
3. Open the drain point.
4. Allow a little oil to flow out before collecting the
sample.
5. Fill the bottle tightly to 3/4 full.
6. Close the bottle by tightly screwing the cap and
check the information on the label.
7. Close the drain point.
8. Top up the engine oil if necessary.
