High Mileage Oil

S ome cars require conventional or synthetic oil, while others need high mileage oil. In case you own a well-worn vehicle that has been your road-companion for over 75,000 miles, it is probably time to switch to a high mileage oil.

Running this type of oil will help extend the life of the engine. It can be surprisingly effective if it is constantly used because it has powerful ingredients that can protect a motor from easily wearing out. it can also make the seals more flexible in order to prevent future leaks. Generally, high mileage oils cost a little bit more than the standard lubricants but their benefits outweigh other oils in the long run.

Engine Maintenance Tips

A functional car requires regular maintenance to work at its best performance. This means keeping in a good shape all its parts in order to reduce later expenses. Let’s have a look at a few basic maintenance tips that are useful for an engine’s good functionality over time.

• Regular oil checks
  It is said that oil is the engine’s blood, and because inside there are plenty of parts that are constantly rotating, they need to be often lubricated. Over time, the quality of the oil decreases and little amounts of it get burnt off inside the engine. This is the reason why you constantly need to change its oil, otherwise, the friction will start increasing, leading to mechanical wear. In this case, the engine will be exposed to sludge and carbon deposits.
• Prevent the engine from over-heating
  The fuel that burns inside an engine generates a huge amount of heat. The cooling system is responsible for keeping a low temperature of the engine, but in case of possible malfunctions, the engine will be exposed to overheating. It is recommended to check the coolant’s levels and see if there are any leaking signs. In case the cooling system works fine but the engine’s temperature is still aggressive, you should probably take your car for more detailed verification.
• Verify the timing belt
  The timing belt should be regularly checked for wear and tear signs and should be generally replaced from 60000 miles to 90000 miles. It ensures that the valves worked by the engine’s camshaft open and close at the same time with the pistons. If it gets damaged it will probably snap while the engine is running and this can lead to serious engine issues.
• Verify the air filter
  The air filter is the part that keeps debris and dust away from clogging the engine. If the air filter gets clogged, it will not be able to give the engine proper ventilation, leading to poor performance and a decreased power. It would be recommended to change the air filter at regular periods of time according to your car’s user manual.
• Change worn-out drive belts
  Because the drive belt is directly connected to the alternator, air-con compressor and other accessories from the engine, it can create great damages to the entire system in case it breaks down. You should pay attention to possible noises that may appear over time because they might suggest an immediate replacing. You can check the drive belt every time you change the oil.
