My ten bottles of millers arrived this morning
Just been and added a full bottle to the tank when i filled up (5 litres in tank added 40 litres of petrol to full) It states a full bottle to 50 litres of fuel but cupra only holds 45litres.
Shouldn't be a
problem should it?
Will do some airflow and timing pull logs tonight to compare, then do it again in a few weeks as its meant to take a full tankfulls to get max effect?
