I have a Thinder Tiger 54 4 stroke engine. The manual says run at least 30% lub with 15%nitro.
Anyone else running this engine or any other for stroke, and what fuel are you using? Would 2 stroke 15% nitro and 18% lub be ok?
Thanks for your input.

I use PowerMaster YS 20/20 in every glow engine I own........

I use regular 2 stroke 18% oil fuel in all my engines.

I use the combination oil that is 75% synthetic and 25% Castor oil
