My company has been a Schaeffers dealer for some time, primarily for use in our company trucks though. I have been running the 5w20 in my two fairly new Hondas for over a year now with no trouble. They are both the 2.4 four cylinder. Has anyone else used this oil for any time and with what results? It is supposed to be good stuff, but many people do not even know it exists, and you cant exactly go buy it anywhere.
