I've been using it in all my equipment for 30 plus years and never had an engine failure. My Z turn is 5 years old and mows at least 6 lawns a week. No smoke and still has great compression. In a snow blower I would concider using 5W-30 for easyer starting.

You should certainly change it when putting the machinery up for the winter and I used to make a point of changing it at least once during the season. __________________ To view links or images in signatures your post count must be 10 or greater.

Thanks Most if not all manufacturers call for straight 30 weight in a 4 cycle engine,but 10w30 should be a good alternative.
