What oil for my xxxxx motorcycle?

This seems to be a very common question, and even if its been written before is worth going through again. This is the simple version as there are a wide variety of bike from scooters, cruisers to racers

Do not use car engine oils they will cause wet clutches to slip.

Motorcycle shops are your best source, auto shops often have the oil but make sure it says motorcycles.
The labelling will tell you but read it carefully.

Four stroke or two stroke?, this you will have to know or find out and is quite important for your engine.

Two strokes burn some oil with the petrol so you need two stroke engine oil which is mixed with the fuel either by mixing with the petrol and putting in the fuel tank or via an injection system with a separate oil tank under the seat or side cover.
Two strokes will also need two stroke transmission or gear box oil, this lubricates the gears and clutch and needs changing when servicing.

Four strokes use the same oil to lubricate the engine, gearbox and often the clutch, so it needs changing often.

There are mineral oils, semi synthetic and full synthetic, with a big difference in price, so your budget may be a deciding factor.
Mineral oils are fine for low stress commuters.
Semi synthetic works in most bikes.
Full synthetic for the high power race bred,or you just want he best.
The weight or "W" value will depend on the bike, the usage, the tempurature etc
For this you need to consult your manual, read the labels and make a decision.
The staff at bike shops will help if its still all confusing, just by telling them the model and where you ride.
Dont forget a new filter at each oil change

Do u change oil on a 2 cycle

geez mate what planet r u on?
Two strokes require you to put 2 stroke oil in the fuel and the motor gets its lubrication that way. most r 50-1 meaning 100mls of oil to 5l 0f petrol so no you dont need to change the oil on a 2 stroke as you only need to do that on a four stroke

When my dirtbike is finally warmed up it begins to spit and sputter. I wrecked and bent my head pipe slightly. Would this cause my bike to want to die? When it is cold it runs just fine.

Hi, you dont say what this bike is, is it. Two or four stroke engine,
On a 2stroke this type of problem could simply be carbon jumping around between the gap on the plug,
Or a crankshaft oil seal leaking,

I have put two stroke oil in my four stroke lawn mower. What should I do

If you put the 2-stroke oil in the crank case you will need to drain the crankcase oil and refill with the appropriate oil. If you added the 2-stroke oil to the gasoline, you can siphon a gallon or so out of the tank and replace with fuel only to dilute the oil. It might smoke a bit will be OK.
Good luck.

What is the oil to gasoline ratio for a 3.8hp mtd push mower?

Most mowers are four stroke machines and don't need oil put into the gasoline, it has a crankcase to support the lubrication. If you mower sounds like a chainsaw when it's running it's two stroke, if it sounds like most othe mowers it's a four stroke.

If by chance it is a two stroke (which I doubt) use 3oz of "two stroke engine oil" for each gallon of gas.
