RE: DL-50 engine
You may want to go back and talk with someone from KLOTZ. I bought the KL-310 Syn. Oil at the Toledo RC Show and it comes highly recommended by many RC Modelers. This oil is mixed at a recommended 32:1 to 50:1.
I think we need to remember that each oil manufacture has its recommended mixing based on its characteristics. This mixing recomendation for the Klotz KL-310 for a 50:1 mixture is 2.6oz to 1 Gal. of Gas. Each is going to be different based on volume.
ie. Lawnboy Ashless for breakin for a recommended 50:1 is a 4oz to 1Gal.
GATTUSO2170, Checkout the KL-310. I'm wondering if your looking at the wrong oil???? Not Sure.
