Q3. My vehicle has been modified to run LPG (liquid propane gas) or dual
fuel, do I need to change my spark plugs to allow for this?
A3. Generally speaking no. Plugs may not last quite as long as with a
standard petrol engine and the ignition system may have a harder time
generating a spark. The denser charge in the combustion chamber means a
higher voltage is required to jump the gap. For this reason it may help to
reduce the spark plug gap by 0.2mm. If spark plugs become prone to
overheating then it may be necessary to replace with plugs one grade
colder. Also, see Q.25.
