rev up your engines nabob says Scotty does restore work okay
for those of you don't know restore is one of these additives you pour in your engine
and it says it rebuilds your engine as you drive with metal blah blah blah blah
blah well here's the thing if you had an old junker like a 65 Ford and it
was smoking like mad they can actually do something cuz it's all worn out and
the metal particles in it somehow can help seal some of the problems and I've
seen them burn less oil and run better don't ever ever think about putting that
stuff in a modern car that has variable valve timing gasoline direct injection
turbo chargers cuz the metal formulation there can clog a lot of that stuff up
don't ever do that I've seen people doing seen them destroy engines on
some old junker or you got an old mower that smokes a lot give it a try
you know it's on its last legs anyways but don't ever use it on any modern car
cuz that metal can get in there and destroy things so do not use that any
modern type engine especially ones that say they can only take zero w16 or zero
w20 and don't even think about using that stuff, Gary Gutierrez says is anti-lock
brakes the traction control necessary I always turn them off that's if you know
how to drive and where you're driving some of the traction control systems and
anti lock brake systems don't work all that well like GM's GM over the course
of the last couple of decades they got all these lawsuits against them because
they're anti lock and traction control systems weren't made all that well the
software wasn't that good so a lot of people have sued them you take something
like my wife's Lexus it's got an on it and they work fine I've never had any
problems I've never had any customers their problems with them either so it
really depends on the manufacturer and where you're driving how you're driving
because unfortunately it is true that computers can react a lot faster than
human beings so let's say you got one of your tires on ice or
the others on dry pavement maybe our systems gonna be able to
direct to it a lot better than a human being that's just the way that it goes
the computers can think faster than we can in reaction time that's just a fact
but you have to have a vehicle that it works good I like I said the GM ones but
kind of crappy I wouldn't trust my life in one of those I'd rather
to be driving with it turned off and drive it myself and of course if you
driving on dry pavement a lot of that stuff you don't even need in the first place
I scrub says Scotty quick questions you ever think in the future
manual transmissions will it continue to exist the other day some places yes
because there's always people that want to standard transmissions people going
in the mud farmers going into fields heaven on a mild dirt road that turns
into mud going into their farmhouse I mean it's probably always gonna be
reasons that but in the United States the last I checked the figures are a 96%
of the vehicles registered on the road we automated transmissions these days so
but I assume there's always gonna be a certain amount of people that want to
drive on they want to toll really heavy weights they want to be able to choose
the gears control what gear they're in a lot easier so the wheels don't slip so there
will always be a few I see that but I mean they are close to extinction where 96%
of the people aren't using them these days, Ali rec says when purchasing a used
car the car regional specs matter the main problem there is let's say you
buy a car somewhere else not in California but you find out it's got two
California missions that's a big deal because the California missions would
have more emissions stuff they're more complex to fix the harder to get them to
pass the emissions test and States because they have more stringent laws
there and if you noticed a few days ago Trump was tweeting that he
said that he was taking the right away from California that they could make
special regulations that only the feds can do that so who knows which way
that's headed but my advice if you're buying a used car and you plug in one of
those computers and it says California specs I'd passed and buy one that isn't and
those little computers always tell when I plug in a scan tool I can go
right to the data system right to the specs of the car
and it'll say whether or not it's California emissions or just federal
emissions on it this law you have to tell you, Mitchell says
Scotty what's your thoughts on air suspension well there's all kinds of air
suspensions when I was a younger mechanic guys would put air shocks on
the back other cars or pickup trucks so they could lift the back and put more
weight in I knew a guy was a scuba diving instructor he did it on his Chevy
on the back so that he could pump it up when he put on the scuba diving tank so
it wasn't dragging now their much more complex you take Lincoln, Mercedes
they got here computer hydraulic adjustable shock systems use all three
systems and they're well designed they work great when they're working but one
they break hmm you can spend five six thousand dollars on a Mercedes changing
4 of them out so you're talking about big money repairs of course if they use
air pressure eventually the air bladders crack and rip because they're rubber
they leak air then you got to replace them and there's a compressor that works
compressor will break down and the lines can rot and break because they're made
out of plastic and they'll up and get hard and crack so they get to be
expensive when they get old on new cars fine but as they get older they can be a
royal pain in the butt then of course this companies out there that make kits
to replace the air suspension with normal none air ones so
pick your poison on that stuff, so if you never want to miss another one of my
new car repair videos remember to ring that bell
