Nothing but Gassolina

I am awful at understanding lyrics to songs, and I don’t know what that pop/r&b song actually says, the only word many of us non-spanish folk understand is gassolina! Gassolina gassoline… it is getting pricier and pricier! Finally, a co-worker and I have scheduled days where we will carpool from boxborough to chelmsford. Good timing too because we are one car down for about a week or so. The ford escort failed inspection rather miserably, so we sold it on craigslist and bought a new one on craigslist (well, gave a deposit, title to arrive soon).

So, all it this is making me mindful of gas and driving distances.

Then, I took the beetle to get gassed up and the gas attendant told me that with a turbo car you really should fill it up with premium gas, that the regular gas can do damage and cost you thousands down the road. Guess it gives that recommendation under that gas cap too. Hmmmm, said I, and thanked him for the tip.

So, now I am seeing out experts on the matter to learn if this is really important or just a nice thing to do to a little turbo beetle. Any advice? Some websites have told me it’s a myth, others say go for the premium stuff. If I am not enlightened within a week or so I will probably have to call car talk. But i always listen to them online, what time are they actually on the air?

  1. Thanks for the advice… I did calculate that we are getting 28-30 MPG, this means we could get even more by driving efficiently and higher octane gas right?

    Jill, he’s right. The turbo causes an increase in the compression ratio and the higher octane fuel is needed to prevent detonation or knocking. The engine can typically compensate for this by backing of the spark timing, but this means you lose quite a bit of power and fuel efficiency. I’m in the same boat with a Passat that has the 1.8T engine. Sorry for the bad news.
