after doing a brief search on google, it appears that gasolina is spanish for gasoline, and the name of a song by DAddy Yankee.
This in my personal opinion does not bode well for your domain, Daddy Yankee sounds like an American Rapper who I dont think is very well know in the UK and secondly Gasoline is a term more commonly used in the states rather than in the UK, and the term is a spanish term......... with a UK CCtld.
What I'm trying to say is the name appears wrong for the tld. Furthermore there is not a high ammount of PPC ads for this term. (Taken from Esti stats)
It would be wise to take all automated appraisal tools valuations with a pinch of salt and more as tool to provide a lot of stats for very little effort. I know this from my own experience. And if a domain which seems like it is worth a fortune is available think fast but think why is it still available? Before Registering.
Hope this Helps
