one, two, three, four!
Rev up your engines!
It's time for the Scotty Kilmer Channel
today I'm going to help you answer the question, what gasoline should you put in your car
because you don't want to waste money buying expensive gas you don't need, but
you don't want to have the wrong gas your car either, well here's the truth of
the matter, most modern cars are made to run perfectly fine on regular gasoline
just pull out your owner's manual and look inside, as it says here, use octane
rating 87 or higher, fuel-injected engines are all controlled by computers
that make the engine run perfectly fine on regular gasoline, if you throw in
higher octane gas, basically you're just wasting your money and throwing it away
and realize that all gasoline sold in the United States, by federal law, have to
contain certain additives, so that they don't pollute and that they make the
cars run correctly, now unfortunately unlike a milk carton that shows you
everything that's in the milk, they don't tell you anything at a gas pump of what
ingredients are inside, so as to what you're actually putting into your gas
tank, you never really know, because they're not going to tell you, they're
worried about gasoline additive Wars I guess, we're they'll have to put more and
more additive to compete with each other, but over the last forty eight
years of fixing and driving cars, I've learned one thing about gasoline, if your
car runs fine on the gasoline that you've been using, stick to it, because then
you know the attitudes that are in that gasoline, are working quite well for you
as the saying goes, if it ain't broke don't fix it, but of course there are
exceptions, if you want a Ferrari they are made for high test gas and they'll
only run correctly on that and take my old motorcycle rusted in a garage here
it's got 14.5 to one compression ratio on the engine it has to run on high test
gas, but modern technology can make you run on regular gas, even with some of
these modern fast cars, take this four-cylinder EcoBoost Mustang, it's got
306 horsepower when you run it on high test gas, but it runs perfectly fine on
regular gasoline, only it goes down to 260 horsepower is now and if you have an
engine that's really worn up and is all carbon up inside, that increases the
compression of the engine and run better on high test gas, but if
that's the case, you really should have your engine carbon cleaned out with a
pressure cleaning machine, to make it run correctly and not deal with a problem by
just putting high tests gas in it, now a lot of people are asking me about the
use of ethanol and gasoline, now realize most modern gasolines contain 10%
ethanol to boost the octane, now on normal car not made for running on
ethanol, ethanol can damage things, but the gasoline that has 10 percent ethanol
also has additives in it to prevent ethanol from doing any damage, but if your
think about using that 85 then it's 85% ethanol, realize you can use that in one
of those flex fuel cars, it's made to run on regular gas or on this E85 with a
high percentage of ethanol in it, only you need to know one thing about physics
then, ethanol contains about 20 percent less energy than gasoline, so you
generally going to get about 20 percent worse gas mileage than you will with
gasoline, so if you're going to use the E85, hey, realize you're going to get a lot
worse gas mileage, even though it does burn a lot cleaner, so it's your choice
a cleaner burning engine or one that uses more fuel, that's up to you, but
that's nothing that I have to worry about yet, because all my cars are so old
they can't run on e85, they got to use regular gasoline, so the truth be told if
you drive a regular car, running in on regular gasoline will be perfectly fine
it'll run and have no problems from gasoline and remember if you have any
