Synthetic Vs. Conventional
If you have changed the car oil before, then you can tell the difference.
Synthetic – These oils are developed in lads to ensure they have unique strains of desirable lubricating and chemical capabilities. As a result, it enhances the performance of the car engine. They are highly recommended by lube technicians in vehicles that run in extreme conditions like hot weather, cold weather, and rapid elevation changes.
Synthetic has better flow in harsh weather conditions, allowing essential moving parts to get pretty lubricated.
Conventional /Regular - There is nothing wrong with the natural automotive oils. They have been used for years, and they occur naturally in the environment. They are readily available and cheap. However, there is little control over the availability of impurities or unwanted elements in these oils. The contaminants build up over time in the engines, which will halt its performance. You will also have a frequent change of oil.

Duramax Fuel Filters- Buyer’s Guide
A fuel filter is a crucial component of an internal engine. Filters prevent penetration of abrasive particles and resins. However, diesel fuel contains high paraffin content that crystalizes at negative temperatures. It, therefore, becomes necessary to have a Duramax fuel filter.
To buy the best filter, you need to consider some parameters. They include:
Manufacturer - The best Duramax fuel filter will come from a reliable manufacturer. Opt for reputable brands. When buying from online stores like amazon, first read the reviews from customers to get invaluable information.
Price - You don't have to break your bank for a fuel filter. However, be wary of low-ball costs. 35% or 40% discounts are rear, and it might mean the filter is of low quality.
Quality and Solidity - The material used will determine the durability of a filter. All parts should be well assembled.
FAQ:
➢ What oil should I use in my Duramax?
- When it comes to Duramax oils, synthetic oils are far superior and reliable than conventional oils. They exhibit greater resilience to thermal, chemical, and mechanical breakdown. Therefore, a synthetic will be the most ideal.
➢ What fuel does a 6.6 Duramax take?
- There are a plethora of oils in the market, and all brands promise to deliver a stellar performance. Some truck owners swear by Rotella or Mobil 1. Figure out what works best for your vehicle.
➢ What is the best oil for diesel engines?
- Part of diesel engine maintenance involves changing the lubricating oil to ensure the engine parts are operating smoothly as well as enhancing the performance. Then the best oil is the one that enhances the smooth running of the engine and boost its performance.
➢ Is synthetic oil better for diesel engines
- There is a myriad of advantages associated with using synthetic oil on the engine oil. These oils are less prone to coking and less viscosity at high temperatures. More so, they have superior additive stability to allow extended service life. This means they can operate under any conditions without compromising the functionality of the engine.
Therefore, we can conclusively state that synthetic oil is better for your diesel engine. However, it's a bit expensive compared to conventional oil. On the other hand, regular oils might be cheap but might not function under harsh weather conditions.
