00:00Hello, TH here. So I wanted to do a quick follow-up on the differential video that
00:06I did because a lot of people have been asking me questions about what my fuel
00:10mileage is like with the new differential. So I before, so no one calls
00:15me out on it, I drove with this diff, or I have driven with this diff for about a
00:20week I would say, yeah about a week and a bit. I drive it every day. There's a
00:26combination of stop-and-go traffic, a little bit of like 80 kilometer an hour
00:32highway, and in the last two days I've done some extended periods on the highway
00:37at highway cruising speed. My average fuel, I reset it at the beginning of
00:42all this so that I can test it. As the car reads it, my average fuel mileage is
00:479.9 liters per hundred kilometers. Okay, that is pretty good and that is better
00:54than it was before. All right, so I think that what's going on is that a little
01:01bit more torque is going to the wheels when I'm driving around slowly, which
01:04means that the car is being a little bit more efficient. So it's able to get me
01:10going and move me around and do what I want to do with a little bit less effort.
01:15It doesn't actually make any sense because you'd think that the engine's
01:17spinning more to get me to a certain speed, but I haven't changed my driving
01:23style and I think it's the increase in efficiency, the increase in gearing that
01:26is causing it to be better. I think that if I drove this car exclusively on the
01:31highway at highway cruising speeds, I would see my fuel mileage go down
01:34because right now I'm at 100 kilometers an hour and I am sitting at 2,900 rpm. So
01:44I'll let you extrapolate for what that would be as if I was going a little bit
01:47faster. So all in all, I don't have a problem with the fuel mileage and as for
01:52cruising on the highway, some people say it drones. It doesn't. It's not really any
01:56different. My particular setup, which is all-stock exhaust with a Magnaflow
02:00muffler, I don't find that it makes any more noise at, you know, 3,000 or 3,500
02:07rpm than it did a little bit at 500 rpm lower than that. It's not, it's still up
02:12there anyway in fifth gear, so it's still making the noise. It's not really that
02:16big of a deal and as I said, I have seen an increase in fuel mileage. I was
02:22sitting at just over 10 before I put the diff in and now I'm just under 10.
02:27Okay, not a huge difference, but a difference nonetheless. The point is is
02:30that it has not got way worse. I haven't been using way more gas because of this
02:35differential. So hopefully that answers some questions. I will put a link in the
02:41main video to this one so that you can see it and I will put a link to the
02:44original video if you happen to find this video and you have no idea what I'm
02:47talking about right now. So here are those videos. So stay tuned, I've got lots
02:52of stuff coming, hopefully very soon. I'm gonna go on a little vacation out east
02:58in the next couple weeks, but I'm gonna do a couple films before that and
03:02hopefully get them out to you. There's going to be a review, at the very
03:07least, of a BMW 435i that has been tuned to an unnamed amount of horsepower. Stay
03:13tuned.
