Default Nitro fuel recommendation

I've been out of the hobby for quite a while. Looking to start flying again. My plane has a OS Max. .40. I found a place online, for fuel. My question is: is there Regular airplane 2% castor oil / 16% syn oil ok for my engine? 16% oil seems a little low, its been a while. Any help would be appreciated.

I personally use 20% oil in all my fuel, which is easy since I mix all of my own fuel. In your case, add 2 ounces of castor to every gallon and shake it up.

Easy enough to order ingredients online to modify a purchased gallon of fuel. Or you could mix your own fuel from scratch. Order oil and nitro online, find methanol locally.

The actual total amount of oil is 18%. 2% is castor, 16% is synthetic.
