The 1.8 costs on average £439 a month doing 309 miles a week, 1236 Miles a Month and 16,068 miles a Year.
No wonder I have been living in my overdraft for the past year...
That doesn't sound at all right Sam.
Quick back of a beermat calculation based on petrol being £1.10 a litre suggests that's averaging about 14mpg!
There's no way that a 1.8 16v engine on mild cams and 'bodies should be anything like that, even driven hard.
Driven "normally" that should be doing 30-35mpg easily enough, going by experience of various 1.8/1.9/2.0 16v engines on aftermarket management. Even enthusiastic road driving should see well over 20. My old 306 GTi-6 on Emerald/Jenveys was actually better on fuel than a standard '6 to give you some idea.
I'd be checking very carefully what's going on - from memory T&R mapped it didn't they so I would expect the basic mapping to be OK given their reputation and from cars I've know of that they've mapped. If the engine is actually burning that amount of fuel, you must surely be on the borderline of bore washing it - does the oil stink of fuel?
I'm not surprised that the maths for the running costs on anything else, short of a V12 (or maybe an RX-8
) looks positively attractive by comparison!
