rev up your engines, today I'm going to show you how to get better gas mileage in
your car, now I've been a mechanic for the last 50 years and believe me, I've
seen every scam known to man that promises better gas mileage, you don't
want to fall for any of those, for instance there's one that was called the
tornadoes, this asian company was selling it
they claimed, you stick this in the air filter and it would make the air go like a
tornado vortex and get better gas mileage, total nonsense, the things don't
work, now lately some guys have been making videos on this HHO scam, where you
get electrolysis and you make the water turn into hydrogen and your car burns
the hydrogen, but that's a scam too, because you use more energy and
electricity to break the bonds between hydrogen and oxygen than you ever get
burning the hydrogen, it's just a silly thing that people are making multi-level
marketing companies and ripping you off selling these kits, I've even had guys in
the past, claimed that if you put these magnets on your fuel line it makes the
molecules line up and they burn better, of course that's total nonsense
too, years ago a guy gave me one of those kits, he said Scott you're such a great
mechanic, you got to see this invention you get better gas mileage,
well I tested it out and I said, it's nonsense it doesn't work, then he said I
was an idiot and I didn't know what I was talking about,
he sure changed his opinion on me when I told him the truth, but there are real
things you can do to get the best gas mileage, first make sure you got a clean air
filter, realize for every gallon of gasoline that your car burns, it also
burns about 1100 cubic feet of air, if you don't have free-flowing air, you're
going to use more fuel with less air, so just make sure you got a good clean air
filter, then make sure you're using the right oil for your car, it generally
says right on the top of the engine, in this case it says use 5w30 energy
conserving oil, and in many newer cars, it'll say use zero w 10 oil that's a
full synthetic oil that's very light, because the lighter, the oil the less
friction inside the engine, the better gas mileage you're going to use, and remember
to change your oil frequently, because dirty oil, guess what it has more friction,
you're going to get worse gas mileage because there's more friction with dirty
oil, and if you use a full synthetic oil, like this dirty old bottle and I found
lying under some leaves in my yard I forgot about, realize they do flow better
and I've had customers switch from regular synthetic oil and they will get
slightly better gas mileage, now the next thing is air pressure in your tires, you
want to have the correct air pressure or you'll get too much rolling resistance
and get worst gas mileage, and realize if you're really a fanatic about gas
mileage, there are tire companies out there that make special tires that have
less rolling resistance, you will actually get a little bit better gas
mileage, you can check it out it's not made up, they have tread designs so they
have a little bit less friction and they get better gas mileage, and since the
more weight you have, the worse your gas mileage, make sure you got a relatively
empty trunk that doesn't have a bunch of heavy stuff in it, the more weight you
carry, the worse your gas mileage, so basically remove all the excess weight
in your car that you don't need, unless you're going on a trip and you're
carrying a bunch of stuff sure, but for everyday driving keep your car pretty
empty, and perhaps the best tip is drive conservatively, my grandfather had a
customer years ago before they were computers in cars and he said, you tuned
up my car but it's getting horrible gas mileage, what you do wrong, so my
grandfather the mechanic said, okay let's go for a ride, so he went for a ride with
the guy, he'd slam on the brakes at the stop light, step on the gas and tear off
when he was taking off, and my grandfather said, you're lucky you're
getting the gas mileage you do, the way you drive like a maniac, conservative driving
patterns are the biggest thing for gas mileage, that's why when you're on a highway
going 60 miles an hour, you get the best gas mileage, because the car is conservative
it's going at a lower rpm, it's not shift and up and down, you're not stepping on
the gas, stepping on the brake, and here's an odd fact that I found out years ago
if you're driving on the highway you actually aren't going to get worst gas
mileage turning off your air conditioner to cool yourself down, because rolling down
your windows actually creates more wind resistance and you're going to get a little
bit worse gas mileage with the windows rolled down to cool yourself down, then you are with
the windows rolled up with the air-conditioning turned on, so now you
know what you can really do to get better gas mileage in your car, so it will
last as long as it possibly can, and you spent the least amount possible on fuel
