In the power distribution center under the hood. It is the 30 amp fuse also there are 2 relay's there.
10w-30 will work fine.
Check the crankshaft sensor. If the sensor on the Grand Voyager is bad then there wont be any spark.
take it in
5w-30
5w-30 synthetic will work fine.
The John Deere X320 is recommended to run 10w-30 Turf Gard oil in the motor, however any 10w-30 motor oil from a local parts store will work as well.
5w-30 is best to use but yes you can use 10w -30. Any w30 oil will work but 5w30 is recommended
I have a 90 Voayger 2.5 Turbo with a 5 speed and it says to use 5W-30 motor oil. I would assume it is the same, but I am not 100% positive.
