So im sort of an oil freak. Its always been something that has interested me and im a firm believer in Amsoil, Redline, Motul, and Klotz being superior to anything else on the market. I visited shindaiwa's website and saw the "Red Armor" worlds greatest 2 stroke oil. Its junk. I filled a fresh can up of 93 octane, ethanol free, and mixed this oil 50:1 and have used it for a couple weeks. Impressions: Sweet smelling!!! Disgusting sugar smell. I can smell it on me right now(from weed eating just now). Also, My equipment honestly is idling rougher. Not starting as easy. Im telling you, no joke. I know it sounds crazy. I will never buy this again. I used a different can with 93 octane and Amsoil at 70:1 and my equipment was idling smooth and running perfectly. Run normal oil and mix in seafoam if you want a spotless engine, not this garbage. Red Armor= JUNK!
