is there a difference and can you use injector oil as premix. any pros or cons?

For your application a injector type of mixer would be ideal because you ride the street. But since those systems have exsisted for decades, there has been no improvements, and they are very commonly removed from bikes that were originally made to use them. I had one on an old Yamaha 2 stroke 125, and it sucked. I watched the oil level all the time and it never really ran low or needed more oil to be added. It wasn't long before the top end seized, it was a shit system, one that Yamaha has been using since the 1960's, and it they still use it, it sucks.

thanks port. from what I am gathering you can use injector oil as premix, but you can't use premix as injector oil. would this be correct?

some oils are used for both. some are premix only. too thick for the pump.

pull out ten bucks from your wallet and buy the right oil. 927 or klotz

that 4z for the answer. and I have a gallon on 927 in the garage. I just didn't know the answer and was curious. so am I correct that you can use injector oil as premix but you cant use premix only for oil injection because of the viscosity? do I have it correct?

Sounds right to me.

Would you believe the manual for my 66' Yamaha YM1 says you can use 30 weight motor oil in the injector system? Crazy.

Been there done that.............. It works, it's oil it lubricates....

Yea it just burns dirtier and can foul plugs.

In my ultra ghetto days I used cooking oil a few times.......

ok, where are Bob nigyver pics when you need them!

Hey when your broke your broke right! I would steal gas out of the lawnmower or boat or anything else, pour in a little oil (whatever I could find) and go make massive smoke clouds in the field!!!!

My first YZ490 had its own oil injection system, I ran it on straight gas and then kept an eye on the tranny oil level

Careful, we may be required to use something like that in the future

non-detergent straight 30 can be used as a substitute for premix in a pinch.
