rev up your engines today I'm gonna talk about it radical new motor oil it's very
important for people that have cars with the modern engines in them the new oil
is gonna be called gf6 and it's really important for people with those GDI
variable valve timing engines and a lot of modern cars have the little
four-cylinder engines that put out as much horsepower as a v8 take the Honda's
they've had a problem with oil dilution where gasoline was getting past the
piston rings past the lubrication and diluting the engine oil which leads to
engine damage and other GDI engines have had carbon buildup timing chain problems
with the timing chains wear out prematurely well that's what this gf6
oil is made for you can't buy it yeah unless of course you're watching this
video in the future this new gf6 oil isn't going to be out in the marketplace
until May 1st 2020 make sure you look at the label on account oh well because the
label explains it all as you can see on my bottle of Castro here then I using
this old car you go by the service labor this is API service SN SN s M s l and SJ
how the quality of the oil fits your engine and you want to research your own
engine to see what you're supposed to use now as I said it's not gonna be
until May 1st 2020 that you're gonna be able to buy the new gf rated oil
you can see here it's not gonna look like the old one it's gonna look like
this new one that's a different shield 0 W 16 especially for the modern engines
and they're gonna have two types GF 6a and GF 6b and there's a difference
between us to the GF 6 a it's gonna be backwards compatible so you can use it
for any vehicle that's what they're gonna say you should really run your
cars on so they pollute less and less engine wears down the GF 6 a and a GF 6b
that's going to be only for those modern engines don't need the zero
w16 oil which in itself is hard enough to find these days because that is a
relatively new oil and a lot of stores don't even sell the stuff now this new
GF 6 oil has to meet eat new parameters that the old oil didn't
the first one sequence 3h requires that the oil be 33% better stopping oxidation
and deposits in the engine this is especially for those GDI engines that
build up deposits more then it has to meet sequence 4b which means it has to
have improved valve train where so the valves and the cams and everything don't
wear out too early and it estimates sequence 5 reduces varnish and sludge
inside the engine now this is very important and of course it's
historically important to on the early engines they just use oil they had lying
around and after it got dirty it would build sludge in the engine to destroy it
so then later they came with detergent oils the detergent oils contained
detergent which keeps all the sludge and suspension so rather than clock stuff up
it gets in the oil and floats around and then when you change the dirty oil the
sludge goes out with the dirty oil this is just a further improvement of it to
keep sludge and varnish from building up varnish is the real big problem in these
GDI engines they have a tendency running hotter with all that pressure and
turbochargers throwing stuff and so it has to meet that specification then
the gf6 oil has to meet fuel requirements so that they get better fuel
economy it requires nineteen to thirty nine
percent better fuel economy and of course is doing that by the lighter
weight lighter the light is the less viscosity the less friction it is that's
why they gone to zero w16 sequence 6f which is another fuel economy thing
it requires that these oils meet a certain minimum fuel economy in a test
done their sequence eight another test there requires that these oils do less
corrosion that they keep more corrosion from occurring inside the engine then
there's a sequence nine tests an estimate prevents corrosion two tests
that they've been doing for years and they're just making a test more
stringent for this new oil but last but not least their sequence ten says that
they have to have less timing chain work which is the big deal in these little
bitty engines that put out a lot of horsepower the engines are spinning faster and
faster generator they have at least two overhead cams it's not for to have
variable valve timing you do not want chain to wear out earlier now when I was a
young mechanic the timing chains generally lasted as long as the
engine did, unless you went 300 thousand miles and finally wore out they were
bigger thicker chains check out this old Chevy timing chain it's thick gets
strong the new ones are tiny compared to these so they need more protection plus
they're also spinning faster so really why are they making this new
specifications GF 6a and 6b the oil has to evolve just like it did in the past
originally cars used oil that would sludge up then they made detergent oil
but even then most of the cars didn't even have oil filters to filter stuff on
we had a Ford didn't have an oil filter I was a ford fairly it had no oil filter
we would just change the oil and every thousand miles then the oil filters
started making various different viscosities for different usages they're
upping the ante again and making it oil that really is much higher quality than
the old stuff was and it's a real change for the better
I remember they started changing the oil change intervals and I asked an engineer
once ok we used to say to change it every 3,000 now you're saying five
what's the difference well back then the engineer that I talked to said well
Scotty we have to make them more eco-friendly so we're telling you to
change their oil every 5,000 miles now I said what did you change anything he said
no we didn't change anything at all except the mileage we told you to
changing it well these modern allows the gf6 they do have a lot of modifications
to make them better having better additives making the base more pure so
they have less wear because back when I was a young mechanic you could rebuild
an engine four to three hundred dollars really but today's modern engines you'll
go anywhere from three to twenty thousand dollars rebuilding some of
those fancy Quad overhead cam 24 valve you don't want those engines to wear out
prematurely and coming up with this better type of oil is a good thing and I
suppose like everything else when it first comes out they'll rip everyone off
and charge way too much for the oil but when you consider what an engine cost
versus what the oil costs you've got to be better using this law any of those
modern engines with GDI valve timing turbochargers small
four-cylinder engines that put out a lot of horsepower by revving faster you want
to use this new GF 6b oil on those the ones that require the 0 w 16 oil and as i
said the stuff is not yet until May 1st 2020 so somebody tries telling you
they're selling gf6b oil they're full of crap don't buy it now and in the future
when it is out realized that the GF 6b should only be used that call for the 0w
16 if they don't you can use the GF 6a because that's backward compatible use
whatever the manufacturers suggest and let's say you have a car today that
requires zero w 16 oil you definitely want to use it in those when the oil
comes out and you can buy the stuff so now you know a little bit about the
history of engine oil and how this new GF 6 oil is gonna work in your modern
car, so if you never want to miss another one of my new car repair videos, remember
