in this episode of killing a Duramax
00:00:02.360 00:00:02.370 we're swapping out the oil cooler and
00:00:04.730 00:00:04.740 going to synthetic oil because I don't
00:00:07.280 00:00:07.290 want to kick the bearings out of this
00:00:08.690 00:00:08.700 thing
00:00:16.000 00:00:16.010 [Music]
00:00:19.490 00:00:19.500 I'm Gail banks welcome back to Dino cell
00:00:22.490 00:00:22.500 number two last time we hit 711
00:00:26.029 00:00:26.039 horsepower but the oil got hot and the
00:00:30.380 00:00:30.390 oil pressure took a dive as you may have
00:00:33.350 00:00:33.360 seen in my unboxing video we ordered a
00:00:35.780 00:00:35.790 20/20 oil cooler from GM it's clearly
00:00:40.250 00:00:40.260 superior to the seventeen to nineteen so
00:00:44.270 00:00:44.280 let's hop into the control room and I'll
00:00:47.149 00:00:47.159 tell you how we're gonna test it Aaron
00:00:50.110 00:00:50.120 fire me though we had 92 hours on the
00:00:59.780 00:00:59.790 oil package i I thought it was time to
00:01:03.500 00:01:03.510 refresh it 92 hours way over the
00:01:07.580 00:01:07.590 horsepower rating of it of the engine is
00:01:09.980 00:01:09.990 that's like 10,000 miles climbing like a
00:01:15.230 00:01:15.240 40 percent grade totally grossed out at
00:01:18.109 00:01:18.119 120 130 miles an hour I mean you just
00:01:21.800 00:01:21.810 can't get there
00:01:23.390 00:01:23.400 in a stock truck but we can sure as hell
00:01:26.300 00:01:26.310 do it on this dynamometer so we put in
00:01:30.920 00:01:30.930 two fresh 15 W 40 CK for standard oil
00:01:36.080 00:01:36.090 and oh by the way CK four is the newest
00:01:41.290 00:01:41.300 high speed diesel engine oil standard
00:01:45.800 00:01:45.810 from the American Petroleum Institute
00:01:48.140 00:01:48.150 we ran the baseline with with fresh
00:01:51.440 00:01:51.450 conventional oil in the engine mike
00:01:54.260 00:01:54.270 changed out to the 20 20 I'll color and
00:01:57.170 00:01:57.180 now we're going to make a pull at 600
00:01:59.180 00:01:59.190 horsepower 3,300 rpm and see how all
00:02:02.690 00:02:02.700 this works okay we're at about 205 we're
00:02:06.710 00:02:06.720 idling let's build a little heat in this
00:02:08.509 00:02:08.519 00:02:09.690 00:02:09.700 punishment
00:02:17.890 00:02:17.900 I should say let's build a little heat
00:02:20.350 00:02:20.360 in this thing and punish it some not a
00:02:23.020 00:02:23.030 little some but if that all works then
00:02:27.670 00:02:27.680 we're going to punish the hell out of it
00:02:30.210 00:02:30.220 every time we talk about going to 3,300
00:02:33.220 00:02:33.230 rpm it's like a crime against nature
00:02:36.180 00:02:36.190 this engine in this engine stock form
00:02:39.100 00:02:39.110 makes this horsepower at 2,800 and you
00:02:42.490 00:02:42.500 can't hit the 3300 and a pickup truck
00:02:45.100 00:02:45.110 there's no way the governor cuts off the
00:02:47.949 00:02:47.959 fuel about 600 pound P 450 horsepower
00:02:53.110 00:02:53.120 will build a little heat in the oil we
00:02:58.270 00:02:58.280 want to get it up to a stable
00:03:00.640 00:03:00.650 temperature to cook it there a little
00:03:02.349 00:03:02.359 bit and we're looking at the oil
00:03:06.550 00:03:06.560 temperature in the pan but we're also
00:03:10.059 00:03:10.069 looking at the oil temperature coming
00:03:11.860 00:03:11.870 out of the cooler and going into the
00:03:14.559 00:03:14.569 main oil gallery on the engine and of
00:03:18.640 00:03:18.650 course we're looking at oil pressure
00:03:20.460 00:03:20.470 still climbing
00:03:24.080 00:03:24.090 okay let's bring the horsepower up
00:03:30.970 00:03:30.980 500 550
00:03:34.589 00:03:34.599 leave it there
00:03:37.520 00:03:37.530 leave it at 5:15 for a while here comes
00:03:42.110 00:03:42.120 Earl temperature 250
00:03:50.430 00:03:50.440 all right
00:03:53.330 00:03:53.340 okay 600
00:03:54.970 00:03:54.980 [Applause]
00:03:57.680 00:03:57.690 600 horsepower turbine Inlet temperature
00:04:01.450 00:04:01.460 1250
00:04:06.920 00:04:06.930 little over 3,000
00:04:11.890 00:04:11.900 to 62-36 looks like a stabilizing
00:04:16.610 00:04:16.620 00:04:20.640 00:04:20.650 okay
00:04:22.790 00:04:22.800 we're good
00:04:23.650 00:04:23.660 00:04:26.650 00:04:26.660 we are good let me have the SD card out
00:04:31.870 00:04:31.880 of the I - data monster so while we're
00:04:35.380 00:04:35.390 crunching this data we're going to
00:04:38.800 00:04:38.810 change to an soil synthetic 15 w 40 I'm
00:04:44.880 00:04:44.890 really anxious to see how this change
00:04:50.710 00:04:50.720 from conventional dissin thetic does
00:05:01.449 00:05:01.459 all right the AMSOIL is in the engine
00:05:04.609 00:05:04.619 Aaron let's make another 600 horsepower
00:05:07.189 00:05:07.199 run and see how the AMSOIL compares to
00:05:10.759 00:05:10.769 the conventional oil
00:05:15.190 00:05:15.200 00:05:21.340 00:05:21.350 00:05:23.830 00:05:23.840 loggers are on
00:05:26.360 00:05:26.370 00:05:30.280 00:05:30.290 I'm such a data junkie it's ridiculous
00:05:33.950 00:05:33.960 this is like data straight to the vein
00:05:39.530 00:05:39.540 love this
00:05:40.640 00:05:40.650 00:05:45.580 00:05:45.590 00:05:50.490 00:05:50.500 00:05:54.280 00:05:54.290 their fuel ratio is coming down 24 to 1
00:05:58.170 00:05:58.180 the air fuel ratio here is only about 22
00:06:02.590 00:06:02.600 to 1 exhausted
00:06:05.760 00:06:05.770 absolutely fear that gonna be much soon
00:06:10.690 00:06:10.700 in that exhaust
00:06:11.530 00:06:11.540 00:06:13.940 00:06:13.950 by that 630 300 RPM turbine Inlet
00:06:18.860 00:06:18.870 temperature around 1250 1260 will it can
00:06:22.130 00:06:22.140 good their turbo rpm is about 97
00:06:25.400 00:06:25.410 thousand rpm
00:06:28.760 00:06:28.770 here comes our 250
00:06:31.930 00:06:31.940 coming up
00:06:35.110 00:06:35.120 00:06:36.920 00:06:36.930 looking stable I think we've got it
00:06:38.900 00:06:38.910 let's go ahead get the data out of there
00:06:46.330 00:06:46.340 yeah good enough
00:06:52.760 00:06:52.770 all right let's brain bring this card
00:06:56.620 00:06:56.630 all right guys
00:06:58.930 00:06:58.940 it's a Duramax halt l5p
00:07:01.780 00:07:01.790 we're comparing first the oil cooler
00:07:05.000 00:07:05.010 it says 17 to 19 l5p oil cooler versus
00:07:09.379 00:07:09.389 the 2020 the towing capacity of the 2020
00:07:14.810 00:07:14.820 increased like a mother they didn't
00:07:19.580 00:07:19.590 change the rating of the engine on
00:07:21.650 00:07:21.660 horsepower it's 445 as it was before and
00:07:26.180 00:07:26.190 it they added about five pound feet of
00:07:30.140 00:07:30.150 torque
00:07:30.680 00:07:30.690 but the big deal here is how long do you
00:07:35.120 00:07:35.130 run it at the limit you got to dissipate
00:07:39.650 00:07:39.660 the heat in the oil you've got to
00:07:41.060 00:07:41.070 dissipate the heat in the coolant the
00:07:43.370 00:07:43.380 cooling package in the nose of the truck
00:07:45.290 00:07:45.300 is all new we ran fresh oil with the 17
00:07:51.409 00:07:51.419 to 19 cooler here's what we saw 270
00:07:55.310 00:07:55.320 degrees in the pan and 246 degrees
00:07:59.510 00:07:59.520 coming out of the oil cooler into the
00:08:02.120 00:08:02.130 main oil gallery in the block then we
00:08:04.250 00:08:04.260 change to the 2020 cooler still running
00:08:06.830 00:08:06.840 the conventional 15 w 40 oil package we
00:08:10.219 00:08:10.229 dropped to 260 1.9 call it 262 in the
00:08:14.270 00:08:14.280 pan and 236 nominally going into the
00:08:18.409 00:08:18.419 block that's a welcome improvement the
00:08:20.960 00:08:20.970 oil coolers doing its job then we
00:08:23.150 00:08:23.160 changed to the AMSOIL max duty diesel
00:08:26.750 00:08:26.760 oil 15 W 40 CK for standard but it's
00:08:31.490 00:08:31.500 synthetic the cooling is virtually
00:08:34.310 00:08:34.320 identical the thing I like about the
00:08:37.219 00:08:37.229 AMSOIL is there's a CK for standard and
00:08:40.459 00:08:40.469 I think it's CK for /sn and there's an
00:08:43.909 00:08:43.919 other detail to that but basically you
00:08:47.000 00:08:47.010 can meet the standard
00:08:48.490 00:08:48.500 I can put it on the bottle whatever or
00:08:51.760 00:08:51.770 you can exceed the standard the thing
00:08:54.850 00:08:54.860 about the AMSOIL is it doesn't just meet
00:08:57.250 00:08:57.260 the ck4 standard in a lot of respects it
00:09:01.260 00:09:01.270 exceeds a hell out of the standard
00:09:03.970 00:09:03.980 especially in the scuffing cylinder wall
00:09:07.120 00:09:07.130 scuffing Department they're way above
00:09:11.610 00:09:11.620 the test standard for scuffing here's
00:09:15.010 00:09:15.020 the wrap-up on the oil temp right at 9
00:09:18.610 00:09:18.620 degrees in the pan same horsepower 600
00:09:21.850 00:09:21.860 horsepower 3,300 rpm and cooler out
00:09:24.730 00:09:24.740 we've dropped 10 degrees I'd say this is
00:09:27.940 00:09:27.950 a successful this is giving me some
00:09:30.190 00:09:30.200 comfort because I want to go to 800
00:09:32.050 00:09:32.060 horsepower so let's move to oil pressure
00:09:35.380 00:09:35.390 this is really interesting because if
00:09:37.780 00:09:37.790 you if you look at the black bar graph
00:09:41.230 00:09:41.240 here the oil pressure in the 92 our old
00:09:45.340 00:09:45.350 oil that oil had sheared down a great
00:09:50.260 00:09:50.270 deal we were getting in this test series
00:09:53.500 00:09:53.510 sixty point seven psi oil pressure we
00:09:57.490 00:09:57.500 put in the same oil product conventional
00:10:00.490 00:10:00.500 oil and we picked up almost seven psi
00:10:04.240 00:10:04.250 o/l pressure changing the oil now we had
00:10:07.900 00:10:07.910 punished that original oil something
00:10:11.350 00:10:11.360 fears but this kind of tells you the
00:10:14.200 00:10:14.210 products shear down I don't know how
00:10:17.320 00:10:17.330 fast the shear down is was synthetic
00:10:20.260 00:10:20.270 over conventional
00:10:21.370 00:10:21.380 but I think it's greatly reduced so we
00:10:24.790 00:10:24.800 went to the new oil in the early cooler
00:10:26.860 00:10:26.870 and now we're up to sixty seven point
00:10:29.230 00:10:29.240 six psi change to the 2020 oil cooler
00:10:33.270 00:10:33.280 same conventional oil the oil pressure
00:10:36.610 00:10:36.620 went to seventy three point one PSI so
00:10:40.600 00:10:40.610 that's how five and a half psi gained
00:10:43.440 00:10:43.450 just changing the oil cooler then we
00:10:46.120 00:10:46.130 change to the AMSOIL package so the
00:10:49.030 00:10:49.040 AMSOIL was run at the same oil
00:10:50.800 00:10:50.810 temperature and picked up three and a
00:10:54.880 00:10:54.890 half psi 270 6.6 psi that's an almost 5%
00:11:02.410 00:11:02.420 gained an oil pressure the total gain
00:11:04.949 00:11:04.959 from new oil in the old oil cooler to
00:11:08.800 00:11:08.810 the AMSOIL in the new cooler is 9 psi
00:11:12.870 00:11:12.880 running the original oil that was
00:11:17.079 00:11:17.089 sheared down I will I was starting to
00:11:19.720 00:11:19.730 see pressure in this high 50s now we're
00:11:25.030 00:11:25.040 in the mid to high 70s now I've got the
00:11:28.269 00:11:28.279 confidence to change the injectors and
00:11:31.269 00:11:31.279 go for 800 horsepower that's the next
00:11:35.290 00:11:35.300 episode
