The air-cooled Porsche 911s with dry sump lubrication were equipped with a larger volume of motor oil compared to the water-cooled variants. The air-cooled models typically had a total oil capacity of around 10-12 quarts, while the water-cooled versions had a smaller oil capacity of around 8-9 quarts. This larger oil capacity in the air-cooled models helped to ensure better cooling and lubrication for the engine, especially during high-performance driving. **

The indication 1090 on the Unity Media Horizon HD Recorder typically means that the device is not receiving a signal from the cable provider. This could be due to a variety of reasons such as a loose cable connection, a service outage in the area, or a technical issue with the cable box itself. To resolve this issue, you can try checking the cable connections, rebooting the device, or contacting your cable provider for assistance. **

Dry sump lubrication is advantageous for lowered cars because it eliminates the need for an oil pan, which is typically the lowest point of the engine and susceptible to damage from speed bumps, potholes, or other road hazards. By removing the oil pan, the risk of it being damaged is significantly reduced, allowing lowered cars to navigate uneven roads without worrying about oil pan damage. Additionally, dry sump systems provide better oil control and lubrication efficiency, which can be beneficial for high-performance engines often found in lowered cars. **

It is possible to receive police radio transmissions on frequencies between 870 and 1090 MHz. However, it is important to note that police departments typically use frequencies in the VHF (Very High Frequency) and UHF (Ultra High Frequency) bands, which are lower than 870 MHz. Frequencies in the 870-1090 MHz range are more commonly used for air traffic control communications. To listen to police radio transmissions, it is recommended to use a scanner or radio receiver that covers the appropriate frequency bands used by law enforcement agencies. **

Yes, a rental workshop may require an oil separator. Oil separators are essential for capturing and removing oil, grease, and other hydrocarbons from wastewater generated in industrial and mechanical workshops. Using an oil separator helps to prevent contamination of the environment and ensures compliance with environmental regulations. Additionally, it helps to maintain the proper functioning of the workshop's drainage system by preventing clogs and blockages caused by oil and grease buildup. **

Oil paint can release harmful fumes and vapors into the air, which can be toxic if inhaled in large quantities over a prolonged period of time. It is recommended to use oil paints in a well-ventilated area or with proper ventilation systems in place to minimize exposure to these toxins. It is also important to follow safety guidelines provided by the manufacturer when working with oil paints to reduce any potential health risks. **

Instead of essential oil, soap oil, and fragrance oil, you could consider using natural alternatives such as coconut oil, olive oil, or shea butter for their moisturizing properties. These ingredients can help nourish and hydrate the skin without the need for added fragrances or synthetic oils. Additionally, using natural oils can be more sustainable and environmentally friendly compared to their synthetic counterparts. **

The choice between castor oil and argan oil depends on your specific needs. Castor oil is known for its moisturizing and conditioning properties, making it a great choice for promoting hair growth and treating dry scalp. On the other hand, argan oil is lighter and absorbs easily into the skin, making it a good option for hydrating and nourishing both hair and skin without leaving a greasy residue. Ultimately, the better oil for you will depend on your individual preferences and desired outcomes. **
