Ram 1500 problemi accensione

[nigel68]

Corretto: ho approfondito il discorso MDS (che comunque non ha attinenza coi problemi riportati all'avviamento) e riporto quanto scritto sul libretto, facilmente consultabile in rete..

"Engine Oil Viscosity (SAE Grade)
SAE 5W-20 engine oil is recommended for all operating
temperatures. This engine oil improves low temperature
starting and vehicle fuel economy. The engine oil filler
cap also shows the recommended engine oil viscosity for
your engine. For information on engine oil filler cap
location, refer to “Engine Compartment” in “Maintaining
Your Vehicle” for further information.
NOTE:
Vehicles equipped with a 5.7L engine must use
SAE 5W-20 oil. Failure to do so may result in improper
operation of the Multi-Displacement System (MDS). Re-
fer to “Multi-Displacement System” in “Starting and
Operating” for further information."

E ancora:
"Lubricants which do not have both the engine oil certi-
fication mark and the correct SAE viscosity grade num-
ber should not be used.
NOTE:
For 2500/3500 trucks with a 5.7L engine oper-
ating under a gross combined weight rating of 14,000 lbs
(6 350 kg) or greater, SAE 5W-30 engine oil is recom-
mended for all operating temperatures."
