What is the average speed of a car on a highway?
This table shows that the reported average normal driving speed was nearly 66 mph on interstates posted with 55 mph speed limits, about 74 mph on interstates posted at 65 mph and almost 78 mph on interstates that are posted at 70 mph.
Is it OK to run twin engines at low rpm?
Such a thoroughbred is meant for speed, and idling the twin engines at a very low rpm is probably not good for long-term operation. Assuming long distance is still the goal, running both engines at slow rpms may not be a good strategy for this kind of boat.
What is good mileage to engine hours ratio?
For reference I bought mine with 950 hours and 51,000 km. Today I am just shy of 5600 hours and 427,000 km. Yielding 76.25kmh or 47.25 mph. I only idle in the coldest of winter nights maybe 10 a year.
What’s the average speed of a car on the highway?
Parts of the highway were 65-70 MPH zones, where of course most drivers were running 75-80+. The way I managed the trip was to take the car up to speed until the engine started to get too warm, and then coast in neutral long enough to let it cool down to a more regular temperature before engaging the transmission for another run.
How to extend the range of twin engines?
An often-asked question is how best to maximize the long distance capability in a vessel with twin engines. When the owners decide it is time to go on a long passage, perhaps even an ocean crossing, they must look for alternative methods of increasing the number of miles they can squeeze out of each gallon of fuel to extend their range.

Which is better engine miles or engine hours?
Well yes, more would be better. More would mean more miles on the highway than time spent idling. Highway miles are better for an engine than stop and go driving. Engine hours vs. miles, what is high, low average?
What should my rpm be at 70 mph?
Installed an SE 6-spd. Now at 70 mph I am at about 2,550 or 2,600 rpm. At 3,000 I am closer to 80 mph. Like Grillfish said above, I like to keep my rpms around 2,500 rpm when running a constant speed. So if I am tooling around town, I will find the gear that gives that to me.
What causes an engine to misfire at freeway speeds?
The engine may misfire and/or buck while driving at freeway speeds with no fault code stored in the powertrain control module (PCM). This can be caused by an intermittent fault with the camshaft synchronizer assembly.
