Yz 125 oils

[mritch8]

I'm wondering if you guys know any oil that I can use for my 125 that doesn't cost 15 per oil change like the Ams oil I'm using now. If you know any oil that works with wet clutches and I don't have to spend a lot on please let me know

Wal Mart Diesel oil, Rotella white bottle or cheap Wally ATF Type F are the cheapest to use.

Will rotella still work well with the wet clutch?

Ok great. So just any rotella oil that's the correct weight for my bike and I'm good?

[DEMI]

Yeah, save your cash and get the white jug

Rotella 15w40 is what I use in my Yz250x

[mlatour]

2-stroke gearboxes usually aren't picky, anything from a 'thin' ATF to a more viscous 15W-40 will work.

I've tried them all including expensive stuff and for my usage found a diesel rated 10W-30 shifts the best.

I use this, get at most auto parts stores.
Cost $9.99 a quart.

Atf type F = cheap! Rotella is a superb oil but will hang the clutches a bit til it gets warmed up but quality is excellent!

Like the other guy said above--smokers don't care.  I use whatever 10w40 is on sale, or the Rotella stuff.  

Maybe it's just my imagination, but there was a brief period in my life where I was using motorcycle specific gearbox oils, and it actually seemed like I started having clutch issues.

I've never been able to detect any "shift quality" differences between various types of oils.  I'm not saying they are not there.  I just can't tell myself, as I'm usually too focused on avoiding trees to be pondering my gearbox function.

Clutch drag as mentioned, especially cold, is the only difference I've ever felt between oils. For dead engine starts less clutch drag is more critical.

[mlatour]

In my case it's not really clutch feel but actually shift quality, for some reason

either with thin ATF-F or thicker 15W-40 and everything in between I was getting regular missed shifts/false neutrals.

 

An on-going problem during a 4 year period no matter the lubricant I tried but since the switch to

a cheap (re-branded) diesel rated 10W-30 last season, that issue has become pretty much non-existant.

 

Even the expensive Motul TransOil 10W-30 did not shift this well.

Haha thank you, and yes I agree my clutch seems to be slipping a little after the new oil so I'm hoping the rotella will fix that

I run the 20-50 full synthetic in my Harley and 10-40 in everything else good stuff been doing it for years

[master_o_69]

take 400 ml of 10 w 30 and mix it with 400 ml of ATF type f, been using this for years with no issues
