Oil, gas mix Ratio

[Larcor69]

I sure this is an old question, I went looking for something similar, back into 2016
What ratio is everyone using, I just watched a video from obr, about breaking in a new engine, they are saying 28:1, that's like 5oz. To a gallon roughly, I have run gas boats for years always used 8oz to a gallon of gas, also I have always used Amsoil Dominator oil.
I am sure boats are cars are totally different, boats are run wide open continuesly, as cars are up and down with the rpms, I am new to running a gas large scale, so I am trying to learn what I can, Thanks.

Yup, I do the same also. 24:1 break-in & 28:1 after that. Also make sure to use good quality oil from a motorcycle shop, not a lawn care shop.

I noted as I have half a quart of Amsoil Dominator oil, is this good for car engines or should I go with something else?

Amsoil Dominator is amungst the best oils ?? just make sure it's actually for 2 strokes lol

 

[Larcor69]

I only use Castor 927 & have no experience with Amsoil so I can not give a opinion on Amsoil products.

Amsoil Dominator

I'll be doing 28:1 for my 34 reed case . That's what OBR recommends for their engines so that's what I'll do.

My obr34 loves 28:1?

Yup 24:1 for break-in and 1st gallon then 28:1 thereafter. I use Klotz Benol racing 2-stroke oil.

I run the same Amsoil in my King Motor T2000, and I mix mine at around 35:1-40:1 and it still burns the plug a little on the rich side at factory setting on the high and low needles, and it runs just fine like that, sounds really good too. Hahaha hopefully this'll help you out.
