Gas engine spark plug decoder

Most of the Mercedes Sprinter vans cam with a Diesel engine and not gasoline/petrol. So a spark plug reference is irrelevant as diesel motors have no spark plugs.

But, during the Daimler Chrysler partnership, many of the Sprinter Vans, both T1N and NVC3 were badged as a Dodge. And while those with a diesel got a made in Germany Mercedes Benz Diesel motor. The gas options came from Dodge.

For you few gas powered Dodge Sprinter owners, this is for you.

Know the condition of the engine from the spark plugs 👌

1- Good condition

2- Saturated with oil due to a problem in the piston

3- Needs to adjust the (gap) in the new spark plug

4- Evidence that the spark plugs have not been changed for long periods and needs to be changed immediately

5- Saturated with lead due to a high percentage of lead in the fuel

6- Saturated with carbon due to poor combustion, the fuel pump and air filter need to be checked

7- As a result of the engine temperature increasing above its normal rate, and therefore we check the system

8- Needs to change the type of fuel (for example, instead of 80 gasoline, it is 90 or 92 gasoline) or change the valves if it happened in a short period (less kilometers)

9- Evidence of a mechanical problem or a foreign body in the combustion chamber
