I love this....!
Filter the old oil through a Mr. Coffee!!! and re-use it!
Or, or > render down some bear fat and boil soap to get something that is slippery enough to pass as a scooter engine lubricant....or , or - put in some cheap shampoo and bacon fat..
Shoot...4 bucks for a Qt of oil is crazy when we've only spent a few thousand $ for our scooters. 15 mins to change the oil is wasted life.
I say, never change the oil until you feel her starting to seize ...just a touch! Then push her home and get out the coffeee maker.
I love this ....Stig
