Five Questions To Help You Decide Which Diesel Oil To Use

If you're confused when it comes to choosing the right engine oil for your truck, don't be alarmed. You're not alone. 

Sometimes it seems like everything is more complicated than it used to be. When was the last time you looked at the toothpaste options at Walgreens. Seems like it's a half mile long with every kind of whitener, plaque remover, gum treatment, breath freshener, ad nauseam. 

In the lubrication world, the various terms may be different, but the level of confusion remains the same. Viscosity control? Shear stability? TBN retention? 

When all is said and done, the best place to begin your oil selection search is to consider your application. Are tractor pulling or drag racing? Is the application stationary, street, or off-road? Here are five basic questions to help direct you to the right solution.

What are your engine oil specifications? 

It’s important to follow what your original equipment manufacturer recommends. Reading your owner’s manual is the key to maximizing your equipment’s performance. Your manual contains vital API information about caring for your engine, including which oil grades are best suited for them. For example: SAE 15W-40, 10W-30, 5W-40 oil? Mineral, semi, or full synthetic base stock needs to be considered.

How important is fuel economy? 

If you’re keeping an eye on your miles per gallon, the right lubricant can help your equipment achieve its maximum fuel efficiency. By squeezing a few extra miles from each tank, you can see major savings over time. A semi or full-synthetic diesel engine oil is your best option to deliver maximum fuel efficiency without compromising engine performance. It can improve fuel economy by up to 2 percent under normal conditions and by up to 3 percent during cold starts.

Does your diesel engine run in a range of temperatures? 

Speaking of cold starts, temperature is another important consideration when choosing an engine oil. Extreme temperatures, whether hot or cold, can be brutal on moving parts in your equipment. Heat can quickly turn an engine into an oven, and the cold can thicken some oils until they’re practically jelly.

How old is your diesel engine? 

Most diesel owners want to stretch the life of their engine as long as possible. To perform their best, older diesel engines require attentive care, and a quality lubricant can go a long way toward maintaining them. For example, is your diesel not running a DPF? Rebuilt for performance? Out of warranty?

Are looking for more horse power or torque? 

Be sure to look at the oil’s data or spec sheet to see if it addresses increased performance, high in anti-wear protection, etc. Look for semi and full synthetic diesel engine oils that use shear stable synthetic base oils. That are also high in film strength, have viscosity control, work with high compression, have a higher TBN retention, and if needed, designed to address demands of turbo or super-charged diesel engines.
