For the record, the engine is a DL50 not a DA and for the reasons you describe is why I suggested that he ask his preffered support network. As you know, when it comes to oils and mix ratios, the opinions on any forum can be very confusing, varied, and misleading. Your experience, while very good information, could lead someone to ignore the manufacturer and or the advise of their selling dealer which, if the engine is still under a manufacturers warranty, would be the worst thing one could do.
I KNOW it's a DL50. You apparently don't get my point.
My reference to the DA was just an example to point out how manufacturers don't always give out the best advice. It's not out of malice or ignorance. Just out of different experiences and opinions.
I'm simply suggesting people use their heads, rather than blindly follow a manufacturers recommendation.
