2005 Chevrolet TrailBlazer LS from North America
It's a bad vehicle because of all the problems it's giving
The fan clutch started making a loud noise, and it started wasting a lot of gas; I use 91 octane, and even so, it's not getting the right gas mileage.
Would you buy another car from this manufacturer? No

If I had a car for 75k miles, and the most major repair needed was a fan clutch, I would jump for joy!
That's not bad at all.
Bad gas mileage? And you even used 91 octane? Uh oh! Another person who thinks cars only need gas to run!
Car's are machines. Machines require regular maintenance. To fix your bad gas mileage, I recommend a good tune-up. Change your spark plugs, air filter, and if possible, your fuel filter (not all cars have a serviceable fuel filter. Your mechanic can tell you whether or not yours does.)
Also, you might wanna try slowing down every now and again. The faster you go, the harder your engine has to work to move your SUV through the air (this is called drag), and the faster you drive, the faster your engine has to run due to the gearing of the transmission.
"I use 91 octane, and even so, it's not getting the right gas mileage."
Why do people continually think that more expensive gas will get them better mileage? Your Trailblazer was meant to run on regular unleaded and should get the best possible mileage on that gas. Ours gets 24 mpg on the cheapest gas available. Wasting an extra $.30 per gallon only burns up more money for you. You should only run the manufacturers suggested fuel in your vehicle. They actually advise against higher than 89 octane in the Hemi engine because it can cause problems for the engine. I'm sure the same is true for other engines as well. If you want real increases in hp and performance, try a K&N filter. It makes a real difference and will actually pay for itself over the life of the car, as it is a million mile filter.
