Edinburgh-Currency. The UK currency is the pound sterling (Â£), with 100 pence (p) to a pound. 'Quid' is a slang term for pound. Several Scottish banks issue their own bank notes which can be used in the north of England and in Northern Ireland, but may be refused elsewhere. UK banks will accept them but foreign banks generally do not.
Regular oil changes (every 3000 to 7000 miles, or every 6 months if it's a vehicle that's not driven often) with the proper type of oil for your car will assure you get the maximum possible mileage and performance from your engine.
Most people change their oil around 3000 miles, but they said the oil is fine up to 5000. Of course, you might want to go with what the manufacturer recommends, as you could void your warranty. Good luck. How many miles you can go, it really depends on what car and what oil do you use. Just check your oil, if it looks very dirty, means time to change it. If it's very dirty it cannot lubricate the engine internal parts properly, the friction increases and the engine wears a lot faster. Source(s): worked as mechanic.
