Conventional 5w-30

But why is it such a popular motor oil? What is 5W oil good for?

The "5W" indicates the oil's viscosity rating, highlighting its excellent flow characteristics at colder temperatures. This ensures smooth startups and proper lubrication even in chilly conditions. The "30" represents its viscosity rating at higher operating temperatures, providing optimal protection and performance during normal engine operation. As industry leaders in automotive lubrication, we offer a meticulously engineered 5W oil that exceeds industry standards. Our 5W engine oil is engineered by experts who understand the ins and outs of high-performance engines.

Are there any benefits one way or the other? Is it worth the extra cost? To start with, the difference between conventional and synthetic oil is all about origins. For this origin story, we need to go back several hundred million years, maybe a billion, before the dinosaurs roamed the earth — wait, before? As these massive microscopic colonies lived, multiplied, and died, they would eventually become covered by layers of sediment, entombing them for millennia. Hundreds of millions of years under intense heat and pressure, in an anaerobic oxygen-free environment, would eventually convert this ancient biomass into what we know of today as crude oil. Conventional motor oil is just one of these. It might seem like a relatively new motor oil, but it was developed nearly 80 years ago, during WWII. In Germany, the chemical processes were used to synthesize lubricants and fuels, liquids, from rich coal deposits solids. Modern synthetic oil is typically synthesized from CH 4 methane , CO carbon monoxide , and CO 2 carbon dioxide , among others. A soup of additives, specific to the application, modifies how the resulting motor oil blend reacts to heat. A 5W conventional oil flows like an SAE Grade 5 in cold weather, easing engine starting and improving cold weather efficiency. The same blend, thanks to its additive load, thickens up as the engine heats up, flowing like an SAE Grade 30 oil at high temperature, maintaining oil pressure and lubricant qualities. Over time, through hundreds of heating and cooling cycles, the additives vaporize or oxidize, leaving the base SAE Grade 5, whose impurities also gradually oxidize and vaporize.

We also offer 5W break-in oil if you need a reliable lubricant while breaking in your new engine.
