This car enthusiast from Grodno, Belarus, thanks to his resourcefulness, does not spend a single ruble on refueling his diesel Volvo. All that had to be done was to change the fuel injection advance angle, replace the fuel filter with an oil filter and start pouring nothing but used oil into the car.

Of course, a reasonable question arises: how to drive in winter? “The engine is really reluctant to start on a cold morning,” the man explained in an interview with AutoGrodno. - In such cases, I added 5-10% of gasoline. In the summer, I stopped doing this, just in the mornings sometimes I asked the neighbors to push the car a little. When the engine is warm, there are no problems with starting.

“The motor feels great,” says the motorist. - The condition of the cylinders and pistons is excellent, the carbon deposits were within normal limits and were easily removed with a rag. But it’s better not to make abrupt starts, because a dark cloud of smoke rises.”

“Hundreds of garages in Grodno are heated with waste oil, some enterprises use it for heating,” the driver answers a question about the environment. - A lot of boilers are also for sale (again, on the "working out"). Everything is official. Therefore, it seems to me that there is no difference where such oil will be used: in my car or in the garage stove.

“It turns out waste-free production,” sums up the auto enthusiast. - I drained the oil, then into its tank - and drove off. My friends give me “working out”. Some even regret that they do not have such a machine.

P.S. Don't do that with modern cars! In addition, burning of used oil is prohibited in many countries!

Many motorists are sure that not only the condition of the engine, but also the resource of transport depends on the speed. This belief is true, since the driving style directly affects the condition of the main components and assemblies. To avoid a quick failure of the engine, you should adhere to the optimal speed in motion.

The danger to the engine is the operation of the car, in which the tachometer needle enters the red zone. In this case, accelerated wear of the power plant is noted. Engine oil begins to lubricate moving parts much worse, and in the future, overheating of the installation may occur.

Despite this, experts recommend periodically letting the engine run at high speeds. This allows you to create a load and additionally clean the internal systems from deposits. It is enough to drive 5-10 km on the highway at high speeds to remove carbon deposits and coking inside the motor.

The downside is constant driving at low revs. This mode of operation also does not benefit the vehicle. Many motorists adhere to this decision and deliberately keep the speed at 2000 per minute. This allows you to reduce fuel consumption. In this mode, the power unit is loaded even more.

The fact is that when driving at low speeds, it is impossible to achieve the correct formation of the fuel mixture. Various deposits may appear on the surface of the cylinders and pistons, which adversely affect the performance of the motor. In addition, at low speeds, defects with the movement of the lubricant composition are noted. This is due to the peculiarities of the rotation of the crankshaft and the reduced level of pressure in the system. Therefore, it is not worth moving at low speeds on an ongoing basis, as this will not help save the motor resource.

In each case, the optimal speed may differ. For example, diesel engines are considered low-speed, so they have a maximum thrust at the level of 2000 - 2500 rpm. The gasoline turbo engine produces a maximum of 3000 - 3500 rpm. Experts agree that it is necessary to adhere to indicators in the range of 2500 - 3000 rpm on an ongoing basis.

In America, a prototype of the eighth generation ring Volkswagen Golf TCR was lit up.
The museum division of Volkswagen Classic showed the racing version of the eighth generation Golf hatchback for the first time in public. The car was almost ready, but dieselgate prevented its launch into small-scale production.
A unique Volkswagen Classic racing Golf TCR was shown at the L'oe Show in Pennsylvania. The auto show is dedicated to Volkswagen, Audi, Porsche and other brands that are part of the VW concern. Unlike the legendary gathering on Lake Wörthersee in Austria, this is only the second time the American festival has been held.
The eighth generation racing Golf was created by Volkswagen Motorsport in Hannover under the rules of the popular international TCR series. It was supposed to replace the successful seventh generation TCR Golf.
Recall that these cars were equipped with a two-liter EA888 engine with a capacity of 340-350 horsepower and two types of gearboxes: a DSG “robot” or a sequential-type Sadev racing unit. Outwardly, they are easy to identify by the body extended by 15 centimeters. Since 2016, more than 100 cars worth from 95,000 euros have been manually built - by the standards of racing technology, this is a large circulation.
Small-scale production of the eighth generation car was supposed to start in 2021, but this did not happen: in December 2020, following the results of the diesel gate, Volkswagen management decided to stop all racing projects not related to electric vehicles.
But a test copy of the racing Golf was kept in the vaults of the Volkswagen Classic division. On this machine, the units were tested in racing conditions, the settings of the chassis and on-board electronics were verified. Since the car participated in sea trials on racetracks, the body was covered with a camouflage film with a camouflage pattern. The sticker has been preserved ever since. And the attentive reader will notice that inside the prototype there is a dashboard from the Seat Leon Cupra.
By the way, along with the ring Golf, a unique example of the third generation rally Golf was brought to America from the museum - this all-wheel drive with the A59 index was created for the World Rally Championship in the early 90s, but the project was canceled at the last moment due to financial problems. A detailed article about this car "Motor" published a few years ago.
