Gas in Mexico is more expensive than in the US and of inferior refining quality from what I remember. Last time I was there was a few years ago.
$100 fill up have been reality to me for a while. My van has a main fuel tank of 30 gallons, and a reserve of about 2-3 gallons.
The boat has a 50 gallon below deck fuel tank, and two 18 above deck tanks mounted away. I have another reserve tank that holds 12 gallons, but I don’t generally carry that one aboard. So all in all I can haul about 100 gallons need be

.
Gasoline at the marina generally runs about 25-30% than dry land stations. I don’t usually get gas at the marina; I haul the boat out and trailer it to a “dry” station. I think the quality of the marina’s gas is an issue also.
I have always believed that Americans have had a “great deal” paying the lower gas prices we have enjoyed for years rather than what fuel coats in Mexico, Canada, and especially Europe.
I am still sticking to my “
not changing a thing about my lifestyle until gas hits $5.00 a gallon ” line, but seeing is gas is already at just about $5.00 at the marina, and home heating oil is at about $4.00 I might have to change sooner than I expected.
NNnnnAAaaAAAaa who am I kidding.
I aint' changing nuttin'
