Car oil ....ok??

Sv`s do use a bit of oil from time to time , especially with a bit of "Spirited" riding . On a normal day to day run and commute it won`t take much but if you have been for a good blatt and have have given it a bit of welly in places it has been known to sip a bit . 100ml is nothing to worry about . As far as filling goes , don`t overfill them as the first symptom is a very hard to find Neutral and a very aggresive gear change .

100 ml in over 2500 ml's

Id say any friction inhibitors present will be quite diluted, and wont cause much interferance in every day operation

On your next oil change (providing you do it yourself) just keep the left over stuff to one side for topping up
