Since your generator must be ready for use in any weather, Mobile One 0w40 is an excellent choice. Try to change every 50 hrs if no filter, 100 with filter. However, you can push to 100 hrs to get you through the outage using the synthetic 0w40 without a filter...keep an eye on the level though if it is a fairly recent machine, made in the last 10-15 years, it may have a low oil shutdown. Do not run over 100 hrs, and only to get you through a storm...50 hrs is recommended.
Use the exact weight of oil recommended by the manufacture of your generator and nothing else which may not be 0w40 weight or may be. I do recommend you use Synthetic oil in any air cooled engine. Any major brand will provide great protection.
The generator should have come with an owner's manual that lists the type of oil. Also, the oil refill may list the oil weight to use.
30wt sae oil
SAE 5w30 Full Synthetic.
SAE 10W30 synthetic oil.
A 3406 Caterpillar diesel generator should not present any oil consumption. The generator could consume one quart of oil per 100 hours and not be considered unusual.
SAE 10w30 Synthetic.
Use 100% synthetic oil in the exact weight as recommended by the manufacture of the engine.
MGS1500HV is the oil pressure for a 1500KVA generator.
this generator capacity of oil is 1.2 us quarts
The oil perisher for 1500 KVA generator is used for the lubrication purposes.
Diesel engine, using gas oil(MGO/DMA).
The way this is usually done is that the oil is burned; the heat then drives some type of heat engine. For example, in a generator it moves pistons. The mechanical energy (energy related to movement) is then converted to electricity with an electrical generator - using the so-called Faraday's Law. A silly and inefficient way: Pure the oil over a cliff, having a rotor catch the oil and spin a generator. On the bright side, this is a green solution.
