i have a 2000 max 5spd.


Q: Will I get considerably less gas milage if I coast at 80mph. instead of 70mph.

 

you'll get the same mileage if you coast at 142mph as you would if you were coasting at 14mph. Coasting doesn't use much gas.

did you mean would you get less mileage if you drive at a constant 80mph? yes. considerably less? no.

 

she gives great mileage if i keep a tad under 3K on the highway..

 

i just took a vacation and got 27.5 mpg.i set the cruise at 75.i normally get around 20 to 21 mpg with mostly highway driving but alot of wot to get through traffic.

 

i got 29.3mpg at 75mph straight for about 300 miles highway only.

 

I read a while ago every 10 mph is about 10% increase in gas mileage.

30 and 65 are the most economical
after that you will see some loss

70 to 80 is about a 25mpg to a 20mpg switch i guess

200 highways miles between school and home-home so yea, and i do all types of time wasting.
