So earlier today, I was playing Mario Kart: Double Dash, and while playing Time Trial on Yoshi Circuit, I felt like reading the ads on the side of the road, and one of them says "Luigi Oil". I was curious as to what it was, so I searched it on the Wiki. However, it seems that we've yet to add Luigi Oil to the List of Implied Items. I'm pretty sure we should add it. What do you guys think?
