Astra, Corsa, Zafira, Meriva, Adam, Agila, Combo
I have a Vauxhall Meriva 1.6L 2004 - 80K miles
- The oil looks black, there is milky residue gunk under the oil cap.
- Pressure test on coolant overflow gave good pressure with no drop on the gauge.
- I lose LOTS of coolant with no visible external leaks. Maybe 1 litre per 200 miles.
