Buyer’s guide for the Best Motor Oil Filter for Infiniti G35 Engine

Driving environment

When choosing an oil for your car, it is important to consider the driving environment. This refers to whether you live in a hot or cold region or whether you use smooth or unpaved roads. Different conditions strain the engine in different ways. This therefore means that you should pick an oil that is suitable for your environment. For instance, a low viscosity oil or rating 0W-30 is recommended for people in very cold regions

Manufacturer recommendations

Different engines use different types of oil as stated by the manufacturer. This information can be found in the car owner’s manual or by asking a qualified car professional. For Infiniti g35, Nissan recommends SAE 5W-30 oil. Always use the oil recommended by the OEM.

Oil capacity

Oil capacity refers to the amount of oi needed by the engine for every oil change. Usually, this depends on the engine size and the size of the car. Cars like the Infiniti G35 have huge V6 engines that require more oil than say, a small Toyota sedan. The Infiniti G35 has an oil capacity of 5.4 quarts. Therefore, as you buy oil, ensure you buy enough for your engine.

Age of the engine

The demands of an old engine are quite different from a new engine. Old engines are commonly referred to as high mileage engines. An engine is said to be high mileage if it has done over 75000 miles. Full synthetic oil is recommended for such engines because it contains less impurities and hence minimal accumulation of sludge. Additionally, there are high mileage oils designed for these vehicles. High mileage oil is usually indicated on the bottle.

How to Change Engine oil for Infiniti G35

  • Remove oil filter cap. Pop the hood of the car and find the filter cap. Remove it carefully by unscrewing it
  • Use a 10 mm attachment wrench to eliminate the spread that hangs by 14 bolts. Most bolts are located along the external edge with two in the rear, two on each side and two at the focal point of the spread. The rest are located on the front edge. Once the whole spread is taken out, you will have from the oil plug to the oil channel
  • Place the removed channel dish under the attachment and loosen the oil dish jolt. As you do this, be careful so you don’t get oil on the wrench
  • Once the channel plug is free, pour the oil out with your hand. The oil may be very hot and may spout out rapidly so be careful in this step. Use quick movements to pull the plug jolt out and prevent the oil from spouting out
  • Next, let the oil completely drain out. It is best to wait a few minutes to completely drain out the old oil
  • After the oil is drained, remove the oil channel with the wrench. Be careful as the channel may be hot as well. Once off, there may be more oil inside. Let the oil here drain as well. Also ensure that the gasket is off. Sometimes, it may stick on so tightly that you may need an entirely new channel
  • After a few minutes of draining, wipe the channel plug before planting in a new channel.

Installing a new filter

  • With the channel attachment cleaned, it is time to put a new washer in. This can be done by screwing it on with your hands.
  • Now that a new channel is installed, start pouring in new oil in. Do this carefully to minimize spills and wastage
  • For lubrication of seals, pour a little of the new oil around the dark ring seals. Use your finger to spread the oil all around the seal

Putting in the fresh oil

  • Using a pipe, gradually pour in the new oil into the opening. Ensure there is no spillage. Here you will use between 4.5 and 5 quarts of oil. As a general rule of thumb, it is better to under fill than to overfill
  • Once added, replace the oil filter top onto the motor spread
  • With everything in place, start the vehicle and let the engine run for about two minutes as you check for any dribbles. If everything seems to be working fine, bring down the vehicle and let it sit for another 3 minutes.
  • Use a dipstick to check the oil level. It should be between H and L markings. If necessary, add more oil but make sure you don’t overfill
