I have a Saito 120s 4 stroke, and a magnum 91 4 stroke. I have never run 4 strokes always had 2 strokes so wanting to know what fuel to use? Both engines are used and appear to be used quite a bit so should be broke in.

I run Wildcat brand Premium Extra 15% Nitro with 18% castor/synthetic oil in both my 2 and 4 stroke engines.

I use this Wilcat 2/4 at 10% with 18% full synthetic, as recommended by LASER engines UK. I've run it about 12 years, Saitos thrive on it.

150 rpm down from peak with the tank half full. When using a regulator I run them at 50 rpm below the peak.
