crankcase oil

[killer454]

i have looked for this answer in the forum and thought i found it but now i dont know.

i read on here somewhere to run 75 or 80 weight motorcycle 2-stroke transmission fluid (maxima mtl) no automotive oil.

now i looked in the free manual and it says to run 10w30 motor oil as in automotive oil.

this is my first 2-stroke and i think i allready screwedup by puting sae30weight in the crankcase,luckely im having trouble with the carb so have not ran it much on this oil.
got the 30 drained and picked up this (valvoline high performance sae 75w-90 gear oil.

can anybody please let me know which one do i put in this 1998 blaster?
10w30 or 75w-90

thanks for the help

use belray 80w. some ppl have good luck with type f tranny fluid too

you can use 10w30, 5w30, 10w40, and ATF.
there is also the SAE80 stuff made for it too.
all will work just change your fluid ever so often and you will be golden.

Be careful using regular motor oil like the 10w30, 5w30, etc, as it is likely to contain friction modifiers which are bad for your clutch. It will cause slippage. Your best bet is something like belray transmission oil, or ATF.

use atf type f , i use it and it works great. just change it more often than normal, which is fine cause you casn change it out about 5-6 times more than if you buy the 11 dollar a quart stuff from the dealership.
