What oil to buy for a service?

Forgive me for sounding thick, but the last time I did a service on a car you could just use Castrol or Duckhams oils and all would be fine.


Now with newer technology all this has changed.


I am going to do a service on my Renault Megane 1.4 16 valve RT. It states in the owners handbook that 15/40 or 15/50 is reccomended, but I am unable to find a suitable oil at my local outlet. I saw one there that was 10/40 semi-synthetic and conforms to ACEA A3 (that is the one thats recommended). would this be a decent oil for my car please


thanks

the 10/40 would be fine.


I DO NOT recommend ';just buying the cheapest';What oil to buy for a service?
Yes, that would work fine.
you need to drain all the oil out of your car first but just buy the cheapest they all do the same job and you could save money that way.
