hi, first post n all that. i need to service my partners 1.6 8v petrol. a few questions to this very very quiet forum (is there a better one that is busier and more popular???) how is best to determine which oil filter element i need? there are at least 2 listed ! and where is the fuel filter and whats the best method to remove it ? What are peoples recommended oils? im used to modern high perfomance diesels as i have an octavia 2.0 140bhp tdi which absolutely must have the dogs dangly bits of oils. but the xara is petrol and not even 16v so thinking i can get away with either halfords own brand or 10/40 magnatec?? or should i go the whole hog and go for the 0/30 castrol edge in such an old motor? opinions please are greatfully appreciated.
