My car is using a lot of fuel?
So I drive a 2001 honda accord V6 and It has 105,000 miles on it and has been well maintained. I usually just use it to drive to school and maybe a few errands and I usually only have to fill up every two weeks but I filled up on Thursday and today's Monday and I'm about at a half tank somehow, what's the deal with this.
Not necessarily the problem, but the first thing I think of when fuel consumption suddenly skyrockets is a thermostat stuck open. It can cut fuel economy in half.
It is easy to check for. When the engine is cool, start it and feel the upper radiator hose as it idles. It should stay cool to slightly warm as the engine warms up, then rather rapidly become too hot to grab when the engine reaches operating temperature. If it warms up as the engine does you will save money by replacing the thermostat.
Check for a vacuum leak.
- Does the fuel tank size have any impact on fuel economy between vehicles? For example the new Honda Accords have a 56 Litre tank while the CRV has a 53 L and the Rogue a 55 L. Now the 2 latters are compact crossovers and are arguably bigger in size than the Accord, so would that mean they are using up more gas? Would that mean its better to buy the Accord if we were going based on just gas mileage?
- Buying my first car and want to choose the right car I need something with a lot of room and thats safe? I've been looking at the honda crv, kia sorento, chevy traverse/equinox, acura mdx/rdx, nissan maxima and buick enclave. I really want something thats going to last atleast (6-8) years without having to replace the transmission or engine I want something very reliable and i'm willing to pay more for something that will last than having to replace major parts in a short time thanks for your help!
- When to start using Fuel Injection Cleaner? I have a 2009 Honda Civic with 57K mileage. I drive about 150 miles a week.(Not including Saturdays/Sunday) I'm not sure when to start using Fuel Injection Cleaner, but if I do, what brand should I use? Or is it too early for me to start using it.
- If your car was starting to have a lot of mechanical issues (see details), would you go for repairs or buy a new or good used car? My 2002 Honda Civic is suddenly having a lot of problems - SRS dash light always on, AC doesn't work, squeaking and thumping underneath on front passenger's side and brake pedal, and passenger side mirror is loose.
