What are the disadvantages of using 95 fuel instead of 98 in our 1.8T?
Im using 98 anyway and driving on LPG most of the time, but what would change on 95? Less power on high rpm? More knock retard? My tuner said its not recommended to do stage 1 on my 180 engine on 95 but I didnt have the time to ask why so there I am.
