I agree with xseler, the Echo oil is a quality oil and should give good service in your china girl engine with a well tuned carb, Lucas also makes a synthetic blemd oil that I think would be a good choice, the Echo oil can be bought at any Home Depot Store which makes it a good choice if you have a Home Depot close by.
