As per the post title really. Halfrauds are stupidly dear so i'm looking for a decent price as my change is due.
Not really sure what the relevance of my technical understanding is? Could you not argue that about the dvd player or the lawnmower you dont quite understand?Halfords only have one oil suitable for Skyline's, Mobil 1, and even that's not the best option available as elsewhere, try Opie oils who advertise on here for example, where you can get a far better lube than any at Halfords and probably for similar or less money.
I would recommend you read some of the oil related threads on this forum before you go wasting money on oil which you'll have to change every 2000 miles or alternatively rebuild your engine every 3 years or so.
I have to be honest here, what are folk's with so little understanding of motor mechanics doing buying a car like a Skyline?
