Dexos 1 vs Dexos 2

We will compare different features for Dexos 1 vs Dexos 2. Dexos oil was designed by General Motors (GM) as a fully synthetic engine oil suitable for many different vehicles and all their engine specifications. There are two types of Dexos such as Dexos 1 and Dexos 2. We are looking closer at the differences for Dexos 1 vs Dexos 2.

Dexos-approved engine oil should always be used, to ensure that your vehicle receives optimal performance and protection against potential damages. Just like GL4 vs Gl5, we make a detailed comparison.

What is Dexos 1?

Dexos 1 is General Motor’s engine oil specification designed to enhance fuel economy and protect its engines. Compatible with both gasoline and diesel engines, Dexos 1 provides protection beyond ILSAC GF-5 and API SN industry standards.

Dexos 1 oil must meet specific criteria in order to be certified as such, including passing various tests designed to demonstrate its ability to reduce piston deposits and enhance fuel efficiency while possessing low HTHS viscosity to minimise friction within an engine.

GM employs a licensing process for dexos-approved oils. Only those products approved can bear the label of dexos-approved. Using unlicensed oils in GM vehicles could result in engine damage not covered by warranty; licensed Dexos oils can be identified by the new dexos logo; any oil lacking this logo does not qualify.

What is Dexos 2?

Dexos 2 is a multi-purpose oil designed for both diesel and gasoline engines, including those found in GM light-duty engines found in vehicles such as the C8 Corvette as well as some European gas engines. Furthermore, this multipurpose lubricant may be found in turbocharged gasoline direct injection engines from GM where low speed pre-ignition may be a concern.

As with other Dexos-branded oils, Dexos Motor Oil must meet API GF-5 and ACEA Europe testing standards as well as numerous additional GM tests, including those specific to aeration resistance and protection from low-speed pre-ignition.

Dexos 2 also requires a lower HTHS viscosity than Dexos 1, as its modern formulation requires it to flow quickly through an engine under load and ensure it doesn’t clog the DPF (diesel particulate filter). Furthermore, low viscosity helps ensure the oil consumed by an engine doesn’t clog its DPF filter.

Differences Between Dexos 1 and Dexos 2

Dexos 1 vs Dexos 2 is an important issue for those who are more sensitive to their cars, even though it gives similar results in many areas.

Dexos 1 is an advanced fuel system lubricant designed to protect diesel and gasoline engines from sulfur damage, while also improving their economy and performance. Furthermore, Dexos 1 can even be used in older vehicles without any issue or concern.

Dexos Gen 2 engine oil is an advanced formulation designed to protect against low speed pre-ignition (LSPI). Backward-compatible and backward compatible for use in older vehicles without any issues, Dexos Gen 2 provides superior oxidation and deposit control as well as protection from an issue known as low speed pre-ignition (LSPI).

GM’s Dexos oil undergoes stringent performance standards testing with modern engines to meet them, such as the aeration test, sequence VID test and M271 sludge test. As a result of these extensive evaluations it outstrips conventional or full-synthetic engine oils with numerous added benefits not available elsewhere.

Dexos 1 vs Dexos 2 is one of the most curious comparisons about motor oil in recent years. Only you can identify which oil is suitable for your vehicle by consulting its owner’s manual. Utilizing Dexos oil will help ensure that your engine runs optimally and lasts as long as possible, while any other type could damage your engine and lead to costly repair bills outside your warranty coverage.

Dexos oils are evaluated based on how well they perform in various tests, including the aeration test, sequence VID test and M271 sludge test conducted by General Motors or independent laboratories to ensure they meet specific industry standards. Dexos 1 vs Dexos 2 are not dramatically different products from each other in terms of price.

Dexos 1 is an ideal choice for gasoline engines and works perfectly with most GM vehicles. Additionally, diesel engines with appropriate viscosity and generation may use this fluid too; however it should not be used with large Duramax or full-size trucks due to viscosity limitations and generation issues.

Dexos’ latest specification, Gen 3, provides improved oxidation protection, turbocharger cleanliness, engine performance enhancements and compliance with stricter EPA emissions standards while remaining backward-compatible with Gen 1 oil.

Dexos 2 can be safely used in your GM vehicle, but should never be mixed with Dexos 1. It is essential that the oil intended for your engine be used; otherwise, this could void your warranty and potentially damage its components and electronics. Furthermore, following recommended oil change intervals for your car is key; failing to do so could compromise its condition as well as cause issues with electronics and components of your car. It is enough to mention these for Dexos 1 vs Dexos 2.


Can I Use Dexos 2 Instead of Dexos 1?

Dexos 1 and Dexos 2 both contribute to premium fuel lubricant systems, but Dexos 1 is best-suited to work with more engines, supporting longer oil change intervals, helping reduce pollution levels, and can even improve fuel economy.

Can you mix Dexos 1 and Dexos 2?

Yes, you can mix Dexos 1 vs Dexos 2 on your engine.

Which One Is Better: Dexos 1 vs Dexos 2?

Dexos 1 and Dexos 2 are both excellent engine oils designed to protect engines from damage. While both formulas can be used on gasoline as well as diesel engines, Dexos 1 offers greater versatility; its application extends across both engine types while Dexos 2 may only work well in smaller diesel engines and not full-sized trucks or Duramax engines. This is a good example for Dexos 1 vs Dexos 2.

Both specifications offer protection that exceeds ILSAC GF-5 and API SN industry standards. If your vehicle uses a diesel particulate filter (DPF), low-ash oil should be selected because high levels of ash could clog its pores.

However, if your car does not require a DPF, any oil can be used – just check with your owner’s manual for recommendations as using non-approved oils could void your warranty. Also worth keeping in mind is Dexos oil’s ability to improve fuel economy and engine performance. We made a comparison like in “10w30 vs 5w30”.
