My Clymer maintenance book said to use SAE10-W40 weight oil or a lighter viscosity oil (10W30) in cool climates and a heavier viscosity oil (20W50)in warm or hot climates.
No would use normal fluid
15W-40 diesel oil is typically used as a 'default'. If you operate in a particularly severe climate, you might have to use a heavier or lighter weight oil. If it's a 2008 or newer model year, you need to use engine oil which has API CJ-4 certification.
oil is lighter than glycerin.
You can use any kind of 10w-40 oil for a nighthawk
Most use Synthetic Oil.
Rocket oil
5-w30 is the recomendation from GM. The LL8 inline six has very tight tolerances and requires a lighter viscocity for engine protection.
I'm kind of at a loss that the question even has to be answered but, no, you can not use dry cleaning fluid in a cigarette lighter.
no, it can't be used because it is a bit more flammable and is can cause the lighter to explode because of the pressure
They use the oil God gave them in their oil glands.
synthetic oil
