It's just that you sound so ridiculous. Going 90mph is safe? Come on man.That is all. All the comments about my driving style or my mpg expectations at high speed are just internet noise.

I didn't say it was safe. I said it was safe for me.It's just that you sound so ridiculous. Going 90mph is safe? Come on man.
I feel like the whole break-in period thing is just a myth or doesn’t apply to modern cars at least…Just make sure you do the math yourself, my Guage showed 33.6 mpg. Real math was 30.3. it's winter and cold plus it's still under 500 miles on the odometer. I'm not too worried yet.
For sure it's not as much as as it used to be, but as a mechanic new things are tighter and have more friction then a somewhat used item. Be it engines with the rings and bearing finding their happy place or differentials and wheel bearings wearing in a touch. I'm not expecting amazing gains but I do believe that it will be improved some.I feel like the whole break-in period thing is just a myth or doesn’t apply to modern cars at least…
The engine will have less internal friction after full break in. The piston rings will be mostly seated in the first 100 miles, and the rest will occur during the break-in process. You will get less blow-by and more power after some break-in period, whether that is 100 miles or 600 miles is anyone's guess.I feel like the whole break-in period thing is just a myth or doesn’t apply to modern cars at least…
I routinely drive on Midwestern interstates with long flat stretches, not much traffic and 70 mph speed limit, where you can set cruise control and let the car do its thing, and I can tell you from experience that after 75 gas mileage gets worse, and after 80 it gets much worse and quickly. At 85-90 you are not going to get to 30, but TBH I can't fault Honda for tuning the engine this way.I just set trip B and spent the last week driving across several states to visit family. Over 2000 miles, average speed above 50 mph. Most of my freeway speeds were around 80 mph, occasionally in the low 70s, occasionally 90. Lots of stop and go and lots of stretches of open road no traffic.
Exactly, there is no guideline for what a Civic should get at 80-90 mph, honestly I think 30 mph at 80-90 mph is great. I think my Si would be turning over 3500 rpms at those speeds ? Catch a headwind in cold weather and it is even much worse, fugetaboutet.I routinely drive on Midwestern interstates with long flat stretches, not much traffic and 70 mph speed limit, where you can set cruise control and let the car do its thing, and I can tell you from experience that after 75 gas mileage gets worse, and after 80 it gets much worse and quickly.

Very well stated. And I might add, if one tries to run an entire tank on cruise control at 50 maybe even 60 MPH on a flat road, I could see 45+ MPG being attainable.I routinely drive on Midwestern interstates with long flat stretches, not much traffic and 70 mph speed limit, where you can set cruise control and let the car do its thing, and I can tell you from experience that after 75 gas mileage gets worse, and after 80 it gets much worse and quickly.

Yeah! I bet we could see 80 MPG if we kept it at 25 MPH on a flat road...Very well stated. And I might add, if one tries to run an entire tank on cruise control at 50 maybe even 60 MPH on a flat road, I could see 45+ MPG being attainable.
Nope. Too slow is bad too. 45 MPH is probably the sweet spot depending on the car.Yeah! I bet we could see 80 MPG if we kept it at 25 MPH on a flat road...
Should be easily achievable. This is from my last run up I-5, manually controlling speed at 70ish with the metrics reset just before launching, light traffic, no additional weight in the car. I blame the hills for me missing 45Very well stated.

I’ve ran some tests and 64 MPH is the sweet spot on the cvt. RPM stays the same as 55 MPH. After 65, it jumps up quite a bit.Nope. Too slow is bad too. 45 MPH is probably the sweet spot depending on the car.
For the engine - yes - you have to factor in wind resistance too though. Although my 45 MPH may not be exactly right, it's probably close to the sweet spot, with wind resistance added to the equation. I haven't read Car and driver in a long time - but they use to publish how much engine Horsepower each car needed to maintain 50 MPH and 70 MPH. I may be wrong, but I seem to remember many cars requiring 2x the engine horsepower to maintain 70 MPH as they do to maintain 50 MPH.I’ve ran some tests and 64 MPH is the sweet spot on the cvt. RPM stays the same as 55 MPH. After 65, it jumps up quite a bit.
I’m going to upset someone but years from now we’ll look back at these days of mandates and say the same.@Benzaccord - exactly right. This fact is what caused the 55mph mandate in the late 1970's when the OPEC nations cut off oil exports to the USA. Those weren't fun days....
