Buyer’s Guide for the Best Oil Filter for 6.7L Cummins Engine

Spin on vs Cartridge oil filters

A cartridge oil filter is a type of filter where one only replaces the cartridge when replacing or changing filters. On the other hand, a spin on filter means you replace the whole filter including the housing when replacing filters. Cartridge oil filters are found in older cars. However, over time, car manufacturers prefer spin-on filters as they are easy to install and remove. Their only downside is that they are difficult to dispose of and may ruin the environment if not disposed of correctly. Cartridge filters are more environmentally friendly. When choosing a filter for your Dodge RAM truck, always consider these two options.

Synthetic fiber vs Paper elements

The first oil filters were made of paper. Although they did a good job, they are not as efficient as what we have today: synthetic fiber elements. This is because they filter out all types of impurities including dust, rust, dirt and metal particles. With fewer impurities, the engine is able to work more efficiently to provide power and torque. Synthetic elements are also much more durable and last up to 15000 miles. This means you don’t have to change your filter often and therefore saving you money and effort. When choosing a filter for your truck, always go for a synthetic filter like the ones on this list

Wrench off vs Standard filters

Wrench-off filters are quite popular today and this is because of the convenience they provide. They allow you to use a socket, crescent or open-end wrench when removing the oil filter. All these wrenches are easily accessible. On the other hand, standard filters require a special tool known as strap wrench. For convenience, wrench-off filters are better and should be considered over standard filters for your Dodge RAM truck.

Oil Filter Change Interval

Another top consideration when looking for an oil filter is how long the filter lasts. Some filters last 5000 miles whereas others last up to 15000 miles. For 6.7 Liter Engines, it is recommended that you change the filter at about 15000 miles. Exceeding this limit may cause damage to your engine. Although expensive at first, always go for longer-lasting oil filters as they are cheaper in the long run since you won’t need to change it for a long time.

Car Manufacturer Specifications

When buying an oil filter, always ensure you know the type of filter recommended by the manufacturer. This can be found in the owner’s car manual. If this is not available, check on the manufacturer’s website or consult a qualified mechanic. Since different model years have different specs, it is important you do your research. The wrong filter will not fit your car and if it does, it may cause engine trouble.

Benefits of High Quality Oil Filters for 6.7 Cummins

  • Engine protection: Quality oil filters remove debris such as dirt and metal particles. This reduces wear and tear in the engine reducing wear and tear as well as improving performance
  • Better fuel mileage: With a better engine, fuel economy is significantly improved
  • Great for the environment: With high quality filters like the ones reviewed earlier, the engine is able to run more efficiently. This means fuel is burned completely and in turn, less air pollution.
