Is dexos oil gen 2 Right for Your Vehicle?
While dexos oil gen 2 offers impressive protection, it’s not universally required for all vehicles. The first and most crucial step is always to consult your vehicle’s owner’s manual. This document is your ultimate authority on recommended oil specifications, viscosity grades, and change intervals.
Typically, GM vehicles manufactured from 2011 onwards, especially those with turbocharged or direct-injected gasoline engines, will specify dexos1 Gen 2. Diesel GM vehicles often require dexos2, which has different properties optimized for diesel particulate filters and other diesel engine specifics.
Identifying the Right Specification
It’s important to differentiate between the two main types of dexos oils: dexos1 Gen 2 and dexos2. Using the wrong one can lead to suboptimal performance or even damage.
- dexos1 Gen 2: This is primarily for gasoline engines. Look for the “dexos1 Gen 2” logo on the oil bottle, often accompanied by a specific license number. It typically comes in low-viscosity grades like 0W-20 or 5W-30. This is the specification designed to combat LSPI.
- dexos2: This specification is for certain diesel engines, particularly in Europe, and some older gasoline engines in specific markets. It has different chemical compositions to meet the demands of diesel particulate filters and other diesel engine requirements. Always confirm with your owner’s manual.
Always check for the official dexos logo and license number on the oil bottle. This ensures you’re buying a genuine, licensed product that meets GM’s rigorous standards.
When Not to Use dexos oil gen 2
While excellent for compatible engines, dexos oil gen 2 isn’t a magic bullet for every vehicle. For older vehicles that don’t specify dexos, or non-GM vehicles that recommend a different API (American Petroleum Institute) or ACEA (European Automobile Manufacturers’ Association) standard, sticking to the manufacturer’s recommendation is always best.
Using a dexos oil in an engine not designed for it might not cause immediate harm, but it also won’t provide the intended benefits and could potentially lead to issues if the viscosity or additive package isn’t appropriate for that specific engine design. When in doubt, always refer to your owner’s manual or consult with a trusted mechanic.
