Rev up your engines, charlie g says, why do most modern American
cars have 4 cylinder engines these days, well that's a very good question, the main reason
is because it's cheaper to make 4 cylinder engines, they weigh less, so they get better
gas mileage because they weigh less, their smaller they have to pull their own weight
and their pulling less weight, but they have a lot more power,
now the average 4 cylinder engine has 188.1 horsepower, so these 4 cylinder engines today
actually have more power than the v8 engines did 20 years ago,
now of course everything comes at a cost, if you take a 4 cylinder engine, and you put
in GDI with a ton of pressure and put dual turbo chargers on it, your straining the engine
more and of course if you strain the engine more it's not going to last as long,
so of course that kind of goes along with a lot of manufacturers they don't want their
products to last forever, so if the 4 cylinder turbocharged GDI engine wears out faster,
then you either have to buy another car or a very expensive engine to put in it,
so it kind of fits in with the times, that's the real reason is that their cheaper to make,
they don't last as long, and they get better gas mileage so of course their going to be
going with 4 cylinder engines, plus the cars themselves are getting smaller and smaller
so you don't need a big engine and a big engine isn't going to fit in them anyways, that's
one of the big reasons they went to v6 engines instead of straight 6, a v6 engine is shorter,
you can fit them in a front wheel drive vehicle where a straight 6 is too long and it's harder
to fit them in a smaller front wheel drive vehicle it has to do with size too there's
no arguing that, daniel says what's a cheap and good quality
synthetic oil I only drive 5,000 miles a year, ok that's a very good question because synthetic
oil there's all kinds of different types, the rule is that the oil has to be somehow
treated synthetically for it to be called synthetic oil,
but most of the ones in the US are perfectly fine to use, and since your only driving 5,000
miles a year you got to change it once a year anyways, go to Walmart buy theirs or down
the street the autozone it sells STP synthetic oil and it's like $5 a quart so what the heck
use that it's excellent quality oil, now the super expensive ones, mobile one or
redline the racing ones, they can last more than 5,000 miles but they cost so much more
and you got to change it once a year anyways so just use the regular ones their perfectly
fine there's nothing wrong with using them you don't have to spend too much money,
truth maker says scotty do chip tune devices work,
well they can work the really good ones, but realize that's for old style cars, years ago
the computers in cars had ram chips and it was programmable memory and you could take
them off of the computer and you can put different ones in and if somebody knew what they were
doing, they could put correct ones in for either
more horsepower or better gas mileage, but modern cars the computers are all reprogrammable
the whole computer itself there's no parts you have to change,
so if you're going to mess with a modern car, then you get one of these programmers and
you hope that you know somebody who has a good programmer and knows how to reprogram
it to run the way you want, but the ones advantage of those programmers are, they almost all
have a fail safe so before you do anything it says, store the original software and so
it will store the original software so if you screw something up you can push a button
and it can get rid of the software you put on and reinstall the original software, all
the good ones do that, you mess up all you have to do is push a button
and put the old stuff back on, cloud strife says what do you think of the
1.6 turbo gasoline engine in the Nissan Juke, ok I am not a Nissan fan since they merged
with Renault almost a couple of decades ago, their quality has been going down but Nissan
makes decent engines, it's the rest of the vehicles that often break down the engines
are decent engines, but the Juke itself I just think they look weird, that's a matter
of personal taste I wouldn't be seen dead owning one and driving it around I think they
look weird, but if you don't mind the way they look, if you are going to buy one, get
a standard transmission because they can run a long time, Nissan makes one of the worst
automatic transmissions in the world, it's call Jatco,
Nissan used to own all of Jatco it wasn't even Jatco it was Nissan and then they split
off from the company and decided to call it Jatco and they make the worst automatic transmission
in the world, I would not buy a car with one of those in it,
so if you never want to miss another one of my new car repair videos, remember to ring
that bell!
