rev up your engines, today I'm gonna talk about five things to never do on a new
car after you buy it, now when I was a young mechanic in the 1960s there were
things that you had to do to cars that you no longer have to do when they're
new, it was a good idea to change the engine oil and filter after four or five
hundred miles of driving as the engine was breaking in, but you don't need to do
that today, because the oil like this Amazon full
synthetic, it's better made the metallurgy in the engine is better, they
don't shed pieces off like they used to, so you don't need to do that, and the
same thing goes for the automatic transmission, back in those days we
changed the automatic transmission fluid the first five hundred or a thousand
miles to get anything out, you don't need to do that anymore on modern cars either
when you buy it brand new don't get in and just rev it to the redline and peel
out, you don't want to go full acceleration rpm for the first five
hundred or thousand miles, now there's no problem driving at normal speeds ifthe
speed limit 65 you can easily drive 65, but it's a good idea depending on your
engine, to keep it under either 4,500 for 3,500 rpms the first
five hundred to thousand miles, and that leads into the second thing not to do
and that's don't shift your car at the redline when it's brand-new, just as I
said try to keep it under 4,500 or 3,500 rpms, so the engine can bed itself in, the
piston rings can bet inside the cylinders, you don't want to be revving
it as fast as you can and then shifting the gear and then go on as high, it's not
a good idea to do that anyway in any car, but it's really more important when the
car is brand new, now my next suggestion might sound a little weird but, for
the first thousand miles, probably not a good idea to use your cruise control
because as your engine wears in, it's better to have varying speeds and
varying loads when you're breaking the engine in, now back in the 60s again they
told people the same thing, just don't get in your car and drive 65 miles an
hour for five hours, that speed it might bed in a little bit wrong, it's best to
have varying speeds over the first thousand miles, and the cruise control is
just gonna leave it at one, I mean if you're gonna use it for 20 minutes
no big deal, but you don't want to put it on cruise control and say drive from
Houston to Los Angeles nonstop, and of course realize modern cars everything is
run by computers, the computer actually acclimates the vehicle to your driving
style, you want it to have all the driving you do, in town on the highway
low speed, mid speed, high speed, you don't want to calibrate the whole system just
going one speed, now later on it's not gonna affect it, but as you're breaking
it in, it's a good idea to not use the cruise control
now of course doing so isn't going to blow your car up, but you might find if
you keep your car like me for 10,15,20 years, then you end up getting an engine
that maybe burns a little bit of oil as it's older, best to take really good
care of the car the first thousand miles you drive it, now the next thing to do
with a brand new car is try to avoid just driving short distances, 3 or 4 miles or
something, once it's warmed up it's running really well, but as any mechanic
or engineer will tell you, the most where that occurs on any engine is upon
start up, especially on a cold engine, oils is at
the bottom of the engine and has to be pumped up to the cams to lubricate them,
if you're only driving a little 3 mile trips or two mile trips, and then
shutting it off coming back hours later that's the most where that can occur to
your engine, you want it to completely warm up and then drive it around
some, even if you don't have a new car you're gonna notice a real
difference if you just take short trips for weeks on end, take my wife's Lexus
for example, she's retired now but when she worked at HISD and was a teacher, it
was only two two and a half miles to school so she didn't drive it much, we
decided to go to San Antonio to the Alamo, so we took it out there and part
of the way there the speed limit is like 85 miles an hour, took about two and a
half three hours to get there, then when we came back same thing, you couldn't feel
the engine, you couldn't hear the engine, that longer
trip it cleaned out the engine and it ran a lot better, yeah okay
it was running a hundred percent before it's probably running like 95%, but I
could feel the difference and so could my wife
I just did a blind test and I said, oh look I did something to your car what do you
think, and she got it and said, oh wow it's really smooth now it's ultra smooth, and
I said I didn't do anything we just drove it San Antonio and back
then she got mad at me, now if you live up north in a cold cold winter,
you're probably gonna warm the car up anyways to get the heater to work, if you
think about it down here in hot humid Houston, hey in the summer if you buy a
new car, odds are you're gonna turn the air-conditioning on and let it cool
down before you start driving anyway, so that'll help warm it up, but you don't
want to just like go to the convenience store and back and that's it, you want to
take regular trips with it, if you've got an excuse to go visit somebody cross
town, or even next city hey take it, it'll help wear it in correctly, now the last
of the five things not to do is pretty logical, don't overload your vehicle,
twenty people like the old college kids in a Volkswagen to see how many people
that can fit in a car, don't carry a bunch of weight in your trunk, weight is
gonna get worst gas mileage anyways but the most crucial part of your engine is
the first thousand miles, you don't want to overload the thing either by revving
it too high, or by carrying too much weight, realize that modern cars of
course what are they full of plastic parts why cuz they weigh less, so they're
trying to make these things weigh as little as possible to get better gas mileage
by putting smaller and smaller engines in them to get better gas mileage, well
you don't want to strain that smaller engine by putting a ton of weight in a
car either, stay away from that especially when the car is brand new, and
here's some bonus material, here are things that you want to do so your car
continues to look good, cuz it's a brand new car it doesn't have any dings, it's got
a beautiful paint job, you want that to
last too, so don't do like me don't park your car under trees, trees are full of
what, birds and what a birds do, they crap all over the place and since birds don't
have teeth, they have really strong digestive acids to digest their food
they don't chew things up they just chop them up and eat them, so the bird poop is
full of acid it will eat right into your paint, you don't want bird poop and stuff
to get on your paint, so me I keep a bottle of this goo be gone in the trunk
my wife thinks I'm crazy but every time I see a bird is pooped on the car
I get out and clean it because the heat of the Sun especially here in Texas
closer to the equator, that bakes that bird poop on, it can eat right into the
paint of your car, and also keep a roll of these blue shop towels, they're nice
and soft, they don't scratch so you can clean the paint off and you don't have
to worry about it, plus if you get tar or anything
like that on a new paint, that goo gone is really good for taking that stuff off,
and let's hope you don't follow a truck where a pale of paint falls off and
splatters all over your car, but really if that does happen you got the goo gone,
you run out wipe it off, you can save that paint, now I know it's a new
car but I like this nu finish polish it's a polish for polishing cars, I've
used it for decades now, and the thing about it is, it coats it so well it says
once a year but I don't care, I do it four times a year, once every season in
the beginning so you don't forget, this car is pushing 20 years old and the
paint still looks excellent, so now you know five things that you shouldn't do
to a new car, and a couple of bonus things that you should do, you spent a
lot of money on that new car make it last as long as possible, so if you never
