Aldi sells 1l full synthetic 2 stroke bottles for only $12.99 in their special buys from time to time. Some posters here have claimed you can reduce ratio of oil to petrol this way, but not sure how much. 30:1 or 40 :1 perhaps? I think I'll just stick to the recommended 25:1 and let the mower enjoy the full benefits.

Ahh, if only victa had kept producing the thumblatch catcher series, they would be in better shape today!
