The sticker on my 50V says 3oz per .6 gallon – This works out to 4% (I have no idea why they use .6 gallons since the tank holds a full gallon)
The service manual found here: http://mopedriders.org/article_cat.php?fldAuto=2 indicates 4oz per gallon which is a b it over 3%
It is a 79 which is way after leaded fuel went away, so I don’t think that’s a factor.
Any ideas as to why the discrepancy?
What do you use?
