New 2015 Honda Fit MT for me!

[MetroMPG]

Belated welcome to the forum! Congrats on the Fit - I bet it's fun to drive.

Also, a well-driven manual should spank even the higher rated CVT in city/combined driving.

Need more info there!

I find city eco-driving/hypermiling way more interesting because you can dramatically improve your fuel economy while keeping the same average speed as an inefficient driving style.

And it's far more engaging.

Out on the highway, the major fuel saving technique for most drivers is speed reduction. (Or drafting, but I won't do that for many reasons.)

Admittedly I'm pretty new to fuel-efficient driving so my lack of enjoyment trying to improve my fuel economy in the city may be the result of just not knowing how to go about it. Generally I accelerate quickly to my cruising speed and then cruise in the highest gear possible for the situation. That said, the best I can get in this car (rated 29mpg city) is probably 32 - avoiding all drive-thrus of course.
Before the oil change, I wasn't getting more than 29.

You're right about the highway. It's generally boring, but then again I don't try to have real fun on the highway anyway - cruising along at 80mph isn't really any more fun than cruising at 70-75. I just adjust my speed to try to keep it in the 45mpg range on the little fuel efficiency indicator in the car and figure that's probably the best I can do without doing anything dumb like drafting or turning the car off.

How accurate is your dashboard MPG display? Have you compared it against full fill-ups?

It's never any more than 1.5 mpg off, and it's always optimistic compared to what I actually get at the pump. So if it says I got 40mpg for a tank, the worst case scenario is that I got 38.5mpg.

That's pretty respectable, at around a 4% max error based on your current 90 day average.

The last couple of cars with factory gauges I've checked (Mitsu Mirage, Nissan Micra) have also been in the 4% range. Maybe the manufacturers are getting away from the stereotypical lie-o-meter approach.

The Honda Ultra Green oil will probably actually be called "0W-16" eventually. I'm using Honda Ultra Next, which similarly has no SAE grade for the time being, but should fall in line with the new 0W-8 classification. I don't know if there are plans to have lower 'W' numbers but it's possible!

I had a virgin oil analysis done on the Ultra Next, and it is incredibly thin and has a lot of moly for friction reduction. l'll have an analysis done on the used oil when I get back from a 4k mile road trip next month to see how it held up. If for any reason the 0W-8 seems to provide inadequate protection I'd probably switch to the same 0W-16 Green oil you use.

To tide you over, here are the virgin oil analysis results

[jetto-setto]

Here's the UOA. Sample taken with 5,802 mi on the oil with Blackstone's sample pump (works great). MM reading 50% oil life remaining. I plan on running some 0W-20 Sustina I have left for the next OCI after putting at least a couple thousand more miles on this stuff. Then I'll likely return to it after running the Sustina.

Wow, that iron level is shockingly low. Mine was at 32 after 6500 miles (first oil change on the Cruze). Maybe that's explained by the fact that I have an iron block but yours is AL? But then I would expect to see more AL in your sample, and there isn't much more. Is this a full synthetic oil?

I'm curious. Does anybody else have other ideas? Maybe Chevys come a little tighter from the factory.

Wait, I see now that this wasn't your first oil change. That probably explains it...
