I recently bought a brand-new Mazda CX-7. To ensure that my vehicle will obtain the highest fuel economy, I want to use a particular gasoline for consistency. What octane rating for fuel should I use?
Selecting the right octane rating for your fuel is important because it helps improve fuel economy and performance. It differs based on the recommendations of the manufacturer. For the 2.3L DISI turbocharged engine of your CX-7, the minimum octane rating is 91. If you use fuel that is lower than the recommended octane rating, you may experience problems with your engine. It will also make your fuel economy suffer. As much as possible, use only fuel that has the exact or higher octane rating for your vehicle.
I love taking my SUV out of town and cross-country, that's why I bring a lot of baggage on top of my vehicle. How much is the maximum allowable weight in my roof rack?
Your roof rack is probably one of the assets of your SUV, as it allows you and your passengers to enjoy wider space inside your vehicle. However, in terms of safety, you should observe the maximum allowable weight for your roof rack, which is 100 pounds distributed evenly. It is the same as most of the SUVs, and if you exceed this weight limited, you might get flagged for overloading. Too much weight might also damage your roof rack, no matter how robust and sturdy it looks. Make sure to strap your baggage properly, and avoid having some items stick out dangerously.
My brake pads are all worn out. Which type of brake pads will work perfectly with my CX-7: ceramic or semi-metallic?
If you are looking for brake pads that will last, buy semi-metallic over ceramic. Ceramic brake pads leave more dust, unlike semi-metallic pads. Make sure that the pads that you will buy are OEMs. Do not settle for low cost pads because they will surely wear out easily, and they are prone to create more noise every time you step on them. Invest on high-quality brake pads for ultra-smooth braking and great bite. You might also want to check if your rotors are already up for replacement. Look for steel rotors in case you are replacing them for durability.
It's time to replace the oil of my Mazda CX-7. Can I do it myself?
Of course, you can. Replacing your oil can be a bit difficult for starters, but if you want to explore your vehicle and would love to do things by yourself, no problem. Make sure that your engine is cool before you change your oil. Drain the old oil and refill it with a new one. It is important to lubricate both ends of the filter cartridge before you install it. This is to reduce the friction when the canister cap is tightened down. Don't forget to lubricate the O rings as well to keep them from wearing out. Replace parts that already exhibit signs of corrosion to ensure that your engine will not fail.
