What kind of oil does my 2003 rm 125 need - 2003 Suzuki RM 125

check ur compression dry and wet to see if u have bad rings oil will blow by if bad if ur wet reading is higher than dry. bad rings

quantity is .75 liters, and no, that oil will not work. You have a very high revving engine. You need to get yourself oil for a race engine. Take a trip to your local bike shop, they will have what you need. Even if they dont sell suzuki, its not specific to the manufacturer

10w40 oil will be fine

You can run Motor Oil in the Tranny or we run Automatic Transmission Oil in ours and we change it alot. We also run Lucas 2 Stroke Oil at 40:1. We run our Banshee and Yamaha Dirt Bikes on that also. Hope this helps.

0.75 liters is enough. you can try castrol, or any oil with racing performance.

Hi, firstly look on left side near cylinder base for a cap !its not a bolt[way too big] & usually has a bar arrangement so you can get hold of & twist it!
dont mix oil brands! use a TOP quality oil
as its the only insurance you can apply to it!
[ cheap oil kills engines] use what you can afford! & stick with it!

either 80 or 90 weight gear oil should be fine. and it either has a sight glass or more likely a check bolt to fill it to. it should take less than 1 quart

Use 10w40 motor oil in the gear box. Don't use any synthetic oils, oil marked "EC", or oil with "special" additives. Stick with the major brands; Pennzoil, Quaker State, Mobil or Shell.

Use TWO STROKE ENGINE OIL in the pump. If not using an automatic oil pump, then mix the gas and oil 32 to 1. That equals 4 ounces of TWO STROKE ENGINE OIL to one gallon of gas. NEVER use motor oil in the gas. Only two stroke engine oil.

Please top rate this answer. Thanks!

i recommend and use motul synthetic high performance oil and depending on the type of riding you do mix it at 45:1 for standard riding and about 35:1 for racing.. cost is aroung $15 australian per litre.

I would reccomend amsoil synthetic 10w30
