Hi all

Did a Engine oil change the other day all went well though I have noticed that eurocarparts have given me A5 rather than A1, would this make any difference?

This was used Castrol Engine Oil (Magnatec Fully Synthetic 5W30 A5 Engine Oil (4 Litre))

A5 is better than A1

ACEA

This is the European equivalent of API (US) and is more specific in what the performance of the oil actually is. A = Petrol, B = Diesel and C = Catalyst compatible or low SAPS (Sulphated Ash, Phosphorus and Sulphur).
Unlike API the ACEA specs are split into performance/application catagories as follows:
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

Indeed, it could be better, but you should look at the oil specs, like Ford M2C913-B/C.
ACEA specs could be very generic.
