No,,,,, outboard oil is designed to operate even with water present and lawn mower fuel is not
Using ordinary 2 stroke oil in an outboard is asking for it
Combustion piston engines can have two different work cycles, 2-stroke and 4-stroke. 2-stroke tends to have a better power to weight ratio, but pollute more. A 4-stroke outboard is simply an outboard engine that works the same way as a car engine.
Yes. Use same mix ratio.
2 stroke-NOT outboard, but the same type such as used in chainsaws
No. The bore, and stroke determine the cid. And they are different on these two motors. The 454, has a longer stroke.
Almost all lawn mowers are 4 stroke engines that use regular gasoline (no additives except maybe some StaBil when you store it for winter) and ordinary motor oil, the same used in cars in the crankcase. Usually you would put 10W30 or 10W40 in their crankcases. Briggs and Stratton engines are on most lawn mowers, though Tecumseh is also common. Some have Honda small engines. I suppose two stroke lawn mowers exist but they are the vast minority. You do not add 2-stroke oil to the gas like a chain saw or weed eater. If the mower does happen to be a 2-stroke, I'm certain it would be plainly labeled, probably on the gas cap.
78 lbs, as I assume it is the same as a '99 model
Two-stroke oil is the same stuff whether it says "snowmobile," "outboard" or "weed whacker" on the bottle. As long as the mix ratio is right, you can put the same oil in your snowmobile and your boat.
No. Do not use in your car. It is for use in some lawn mowers and aircompressor motors.
No as all the inline 6 cylinder motors are a 2:1 ration and all the small inline 4 cylinder are 2:3:1 ratio
50:1 is what we use in ours same mix in my outboard on the boat http://macswildboarpage.blogspot.com/ 50:1 isn't enough oil for these engines. Outboard motors run cooler since they are water cooled and may tolerate less oil. If you are using a very high line synthetic oil, then 40:1 is best, If you use a traditional 2 stroke oil (like from penzoil or made for a chain saw) use 32:1.
Yes all 2 cycle engine run on the same idea. Need more help contact me through my board and I will try to help.
One standard push mowers they help make the spark for the spark plug. On riding mowers and electric start push mowers they do the same and there is another set of magnets that charge the battery.
