15 city 23 highway
The fuel efficiency of my 2004 Volvo V70 2.5T varies depending on how we drive it. I tend to baby it around town, decelerating only enough to be safe going around turns, and taking advantage of downhill coasting opportunities. My wife drives a little more conventionally, thus offsetting some of my gains. That said, it gets driven mostly around town, on shorter trips, with a few highway and interstate trips thrown in, and the average is always around 18.5 miles per gallon. On the highway, alone, we regularly get 30 miles per gallon, but that often involves drafting behind trucks (dangerous) and coasting downhill at speeds in excess of 65 miles per hour.
pushing slowly around a parking lot or repair shop lot...no. towing ..always tow with drive wheels off the ground. "coasting"...placing transmission in neutral at highway speeds and coasting downhill, for example, very bad for transmission and also illegal in most jurisdictions. Reason: lubrication of internal components is considerably reduced and results in abnormal wear and early transmission failure. Coasting is classified as not having the vehicle under proper control because of the lack of engine braking capability, and also not being able to accelerate immediately if such action is required. Hope this clarifies the issue.
Once you have achieved highway speed, you would stay in the highest gear, except for steep uphill or downhill grades.
Most likely a failed TPS.
there is a vacuum canister in the engine compartment. It probably has a tiny leak. seal with silicone
when drving around town have it off cause then it saves your gas but have it on on the highway itll give you another gear when coasting so you dont waste as much gas
Driver use gear 'L' or '2' when driving uphill or downhill which required higher gear ratio to move the uphill. Downhill wise, driver use '2' or 'L' for safety purpose. The low gear ratio will use the high gear ratio to slow down the speed of driving downhill and creating 'pulling' force on your car to safety purposes. Gear '2' can be use for overtaking on the highway too provided at the appropriate speed.
People try to "hyper mile" by going slow and steady, driving behind big trucks on the highway, coasting down hills- etc. Do these, but be SAFE about it. Don't tailgate a big truck, it's very dangerous. Do coast down hills whenever possible, do multiple errands in one trip, etc.
If referring to a particular "highway," it is "Highway 66." If you are describing going down a highway, it is a "highway."
