Is it OK to drive a brand new car a long distance?
During every trip, you want to be sure your engine has time to fully warm up. Not warming up can compromise engine performance, particularly during the first 1,000 miles. Trips of five miles or less starting from a cold engine should be avoided if at all possible.
What should my gas mileage be at 50 mph?
I usually drive 80 75 70 65 60 55 mph on the highway. Cost/Gallon: When driving 50 mph, price per gallon is assumed to be the same as the pump price. At higher speeds, the estimated price per gallon is increased based on the additional fuel you use by driving faster.
How many people are licensed to drive at age 70?
Based on data reported by states to the Federal Highway Administration, there were approximately 28 million licensed drivers 70 and older in 2017 ( FHWA, 2018 ).

What’s the average efficiency of a 10 horsepower motor?
Thus, a 10-horsepower (hp) motor has an acceptable load range of 5 to 10 hp; peak efficiency is at 7.5 hp. A motor ’s efficiency tends to decrease dramatically below about 50% load. However, the range of good efficiency varies with individual motors and tends to extend over a broader range for larger motors, as shown in Figure 1.
What’s the average mileage of an older driver?
From 1995-96 to 2016-17, average yearly mileage increased by 65 percent for drivers 70 and older, compared with a 37 percent increase for drivers 35-54. Older drivers have low rates of police-reported crash involvements per capita.
Can a 4.2 liter engine go to 60 mph?
The 4.2 has plenty of power to stay locked at 50 – 60 mph, even with the car full of family & stuff and even on slight inclines. Actually, on a few occasions I was amazed by how much “suffocating” the engine took before the computer decided it cannot go locked anymore.
Why does my truck shudder at 55 mph?
It is only when my speed drifts back and forth during the 45 – 55 mph zone that the problem is noticeable. If I am going up a hill, the shudder occurs at a lower speed, depending on how steep the grade is.
What makes your car vibrate at 60 mph?
Driving at around 60 MPH I feel that the body (not the steering wheel) vibrates. Al 4 tires repalced and balanced including dynamic (on the car) blancing and still the problem not fixed. We picked up a shimmy/vibration at 70 mph, and it was intermittent, sometimes to the point of slowing down to 20 mph to get it to stop.
When do I need to break in my engine?
A long break-in period is not required for the engine and drivetrain (transmission and axle) in your vehicle. Drive moderately during the first 300 miles (500 km). After the initial 60 miles (100 km), speeds up to 50 or 55 mph (80 or 90 km/h) are desirable.
