Beware using the Halfords site to find out the right top up oil. For a Petrol Flair 110 they say Fully synthetic 5W 30 whereas the dealer says, after looking it up, Fully synthetic 0W 30. It was pointed out that using 5W 30 could cause lumpy running. I bought 1L Total from them, at an extravagant price but they throw in a rather nifty plastic wallet thingy to store it with a wipe and velcro on the outside so it stays in one place in the boot! Result!
