every two too three thousand miles depending on how hard you drive the car.
400 miles
It doesnt matter what car you drive. Every 3000 miles or 3 months whichever comes first.
400 miles.
My 02 Trailblazer has 184,000 mile on the original motor. Does not leak or burn oil.
25 mpg
In my book it says 14 miles city and 18 miles highway
19 on highway.
Mine gets about 16 MPG
The light comes on with 2 gallons left; there is no set distance. When that light comes on I only like to drive another 15 miles (usually not stop and go traffic) just to be safe. I once drove mine with the light on for about 30 miles. It was all highway. I turned the A.C. off, set the cruise and did the speed limit. I was pretty nervous for that stretch. I haven't and wouldn't try it again.
Just a guess would be $180.00 based on 20 mpg and $4.00 gas and a distance of 885 miles.
