NCT test for LPG converted Volvo XC90 2.0T
You can see very low emission on the report below. Both low and high idle results for carbon monoxide (CO) show 0.00 vol%. This means that exhaust is clean as a whistle. Inspector at NCT centre said that it was as pure as breathing air :)
Remember - your car could be as Eco-friendly as our Volvo and on top of that you can save money.
