Five reasons to love and hate the Mazda CX-7
Mazda joined the crossover race later than other Japanese brands. Toyota, Honda and Subaru were already working on the third generation of their crossovers, and Nissan and Mitsubishi were working on the second, when in February 2006 at the Los Angeles auto show the Mazda CX-Crossport concept was shown, which after a little tweaking and minimal changes and went to the series in April of the same year as the Mazda CX-7. Mazda had to offer something new in the already highly competitive market, and this “something” was not the usual motor for the family of universal cars.
Under the hood of the crossover, a four-turbocharged 2.3 MZR L3-VDT was registered, borrowed from the Mazdaspeed Atenza sportscar (aka Mazda 6 MPS) with a K04 turbocharger retuned to lower power and more torque. Power for different markets ranged from 238 hp (in Russia) up to 256 hp (in England). Transmission – or six-speed automatic Aisin Warner AW TF-80SC (aka – AWF21, AF40-6, AM6, AW6A-EL), or six-speed mechanics. All-wheel drive Active Torque Split AWD with Haldex controlled electronic multi-plate clutch was taken from the same Mazda 6 MPS. Continue reading
Always fresh: why you can not constantly add oil instead of replacing?
With an oil appetite of more than a liter for a couple of thousand kilometers, a normal driver thinks about piston repair, and the abnormal stops changing oil at all, limited to refilling it. Of course, in the most extreme case, the presence of oil in the crankcase is more important than its quality, but during operation it is actively changing under the influence of aggressive chemistry and wear products. Cleaning with a filter does not ensure full restoration of its quality: it changes as the very basis of the oil, which causes it to become more liquid, and it works or drops out in the form of ash and soot in the places of overheating the additives present in it.
Topping up with new servings of oil slightly restores the amount of additives and fractional composition, but this measure is not enough for long. Quickly enough, the volume of new components is simply lost in the volume of the sludge accumulated in the engine crankcase, and the base number does not recover at all to a normal level.

RADAR DETECTORS NEW GENERATION
If earlier, antiradars constantly “squeaked” and unnerved drivers with false positives, now this problem is a thing of the past. At first, the GPS system came to the rescue, which determined the speed of the car and, accordingly, did not work below a certain threshold, which the driver set at its discretion. For example, you can set the threshold of the device to 69 km / h, and if the speed of the machine is lower – the device will be silent. This allowed to get rid of most of the false positives, but not all. Therefore, a new type of radar detectors with a signature module came (signature from English – signature). Continue reading
