if it is a 4 stroke mower you need a 4T oil. any brand will do although better brands mean better protection. lawn mowers arent too fussed with synthetic or mineral but you need a 4T oil. not actual vehicle engine oil. there is a difference.

if its a 2 stroke any good quality 2 stroke oil works as long as its not marine fortified stuff.the mower should tell you what ratio to use.

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

What kind of oil can i use

semi-synthetic 0w40 oil for the 500,600,700 sportsman quads, check what clutch your ATV has, "cvt" (continuosly variable transmission) clutches, or 'wet clutch'. 10w-40 or the 0w-40 that has the additves for "wet clutch" applications.

What kind of transmission oil should I use for a FXSTD 2000

Your bike came with H-D Syn3 20W50 synthetic engine oil in the engine, primary case, and transmission. There are many other brands of oil that can be used however. Go to their websites and check for their recommendations. Personally, I like the H-D semi-synthetic primary and transmission lube made for the earlier bikes. I think the transmission runs quieter with it in there.

Good Luck

I am wondering if my 2003 yz 450f has separate transmission oil? if so what sort of oil should i replace it with??

no, the tranny oil is the same oil that lubs the top end....your thinking of a honda, honda has 2 differen fills....i would go with a 10w40 semi synthetic. that bike takes 1.2 liters (i still have my 03 yz450f, love that bike:) make sure you replace the oil filter also.

On my kx85 wot oil do ineed to put in the block

The KX 125 is a two stroke and is lubricated with the fuel.
A good quality synthetic two stroke oil will be best in my view as the engine is used by many manufacturers including Aprillia in their RS 125 recomend it. Halfords do a good few types. It has a pump that meters the oil into the float chamber of the carbourettor, very cunning! Unlike my 1956 Lambretta LD150 that used 18 to 1 petrol to oil mixed as it goes into the fuel tank. Yours uses about 45 to 1.

What oil 10W-40 2 cycle or does it not matter

Your Kawasaki klx125 is a four stroke motor cycle. Do not use 2 stroke oil. Use any oil that is JASO MA certified motorcycle oil . In this case use 10w-40. A synthetic oil has some benefits . Your bike will run cooler and shift easier. Do not use car oil or any oil that says Energy Conserving on the label. These oils will shorten the life of your wet clutch and transmission gears ( different additives ).

What kind of oil does my 1999 955i daytona

Use 10/40 synthetic or semi-synthetic MOTORCYCLE oil. Don't be tempted to use slightly cheaper car oils as these are designed for use with dry clutches and contain 'friction modifiers' which make the oil slippier to help the car engines run more economically. These will make the clutch slip on powerful bikes which have a 'wet' clutch running in a bath of engine oil. You can get away with car oils in less powerful bikes.
