ronm - 6/9/2022 08:07 303 oil came in with the New Generation 10 series. It was discontinued in the 70's when Hy-Gard came out. 303 actually contained whale oil, which was banned in the 70's...real JD 303 was excellent oil, better than Hy-Gard in some ways.
That's what the old JD guys told me about real JD 303.
