I'm thinking about Melbourne already and there are two things that can really affect the race: (1) What in the world gives with Renault engines?

The Webbo's terrible black cloud at the start in Bahrain was dismissed by Speed's commentators as some sort of fuel burn off resulting from over filling the tank?




So I guess I'm asking: will RBR use the same engines for Melbourne that they used in Bahrain?
And, (2) Ferrari changed engines for Bahrain before the race. So Melbourne will be the second race for a second set of engines?
Can they use the first set of engines instead? That is, can they re-build the engines they thought were affected by sand and use them again, or, when you change engines, do the rules say you have to toss the old ones out?
Thanks for your thoughts,
