I bought Klotz R50 and have noticed the color is relatively weak. From the bottle it pours like a dark orange, but when mixed with gas 40:1 the color is very hard to notice. It actually makes the gas look like straight gas that turned bad. I was under the impression all Klotz oil was supposed to be blood red, and its kind of inconvenient to have a 2 stroke mix that you can hardly identify. Has anyone else noticed this?
