Asda seem to have some great prices on oil at the moment so I popped in to pick up some Castol Magnatec 5W30 yesterday but noticed there were 2 different tyres A1 or A3/4. Which one is the ideal choice for my WRX? Will be having an oil change in a month or so but at the moment, it has 5W30 in it and could do with a top up.

Its to do with what the performance of the oil actually is.

A1 Fuel economy petrol
A2 Standard performance level (now obsolete)
A3 High performance and/or extended drain
A4 Reserved for future use in certain direct injection engines
A5 Combines A1 fuel economy with A3 performance
