I dont know what oil to buy for my yz 125 03 model what oil should i get?

25.3 fluid ounces

Gear box and engine oil are the same

there is a screw on the side of your clutch cover that is your oil level screw. dont even use it as its not reliable... beside the oil fill hole it will say how much oil goes in. on my 03 yz 125 it takes 650cc yours will tell you. Drain your oil and put how much it says in. I use rotella t oil from walmart its in a white quart jug. Its the same oil the pros use and its cheap as well. dont go spend a fortune on "good" oil when rotella t is just as good.

Calls for 10w30. Any brand mc specific oil will do, along with any of the more expensive brands. If you need to go cheap, buy Type F (only)automatic transmission fluid. Change as soon as oil looks dark.


*Help me out. Rate me!

there should be a 10mm hex bolt head with a phillips screw slot , oil will come out of this when full, use a motorcycle oil, car oils will make clutch slip

where is the oil buddy give me more detail

how do i check my oil level on my yz 250

yes that will work BUT,i have a 03 660 raptor and all i use and recommend is yamahlube.

Nothing significant, don't worry about it. You do NOT want oil marked EC, signifying energy conservation. Such oil will cause the clutch plates to slip and premature clutch wear. If the oil you put in does say EC on the small round type seal simply drain it out and put in the correct oil. Not critical but the sooner the better.
