Hello all, I need some advice / opinions!
I'm due my 2nd service (2yrs/20,000 miles) in a month or so.
I've bought 5 litres of Castrol Edge 5w30 to take care of the oil change, as last time it was changed they put Shell in.

My main worry is, i'm on t&d service, not longlife, do I have the correct oil? I've checked the manuals I received with the car and the specification of the oil type for t&d service is different to that on longlife service plan.
I'd gladly put the Edge 5w30 in, as I am led to believe it is right & best for the car, however will the people at the garage see this the same way and just fill it up with the oil I bought, or will they say, 'you've bought the wrong oil' and 'it could screw your warranty'??
What do you guys think?
