What Is dexos1? | GM Oil Specification

[@edinthecouv]

Dexos is just a spec that GM came up with. They get a kickback on all sold wearing the Dexos label. The grade is the most important you need to adhere to. "Emissions and low speed pre-ignition reduction" I can read that on the label of any oil with the dexos label...

[@thangknowa3288]

Best explanation of Dexos you will find on the web. More and more is expected of oil used in today's engines. They failed to mention new seal conditioners in Dexos. Fully backward compatible, and helps with sooting in direct injected engines that never get a fuel cleaning across the intake valves. Reduced air carried helps with hydraulic needs as well as lubrication. Win-win!

[@TheRichardF10]

I always purchase Valvoline Max Life Full Synthetic and also Kendall with Liquid Titanium GT-1 Max Full synthetic. Both Dexos Approved. Thank you for the explanation.

[@negativeproton1120]

The only thing dexos does it put money in GMs pocket by oil producers having to pay them to put the logo on their bottle. I guess GM figured if you can’t make money by making decent car, come up with some BS and make everyone to pay for it

[@judgedredd8876]

If e.g. your Chevy 5.3 consumes oil try a different brand and maybe go to a 10W30 even if it has no Dexos label. The MOST important thing is to reduce your oil consumption to 1 or 2mm on the dipstick at the 4000 mile oil change interval. Oil burned will clog your piston rings and place carbon deposits everywhere including your catalytic converter thus reducing its life.

[@Demosvibes]

Hi I got impala 2016 v6 3.6l How about Dexos 2 the blue?! I know it's for EU cars but can I use it on my car or it will impact the engine?

[@davidjames666]

Anas Al-Yahya dexos2 is for Diesel engines, and thus the European formula. The USA sold Chevy Cruze diesel uses dexos2. If your car calls for dexos1, be sure to get the mobile1 dexos1 generation2 - especially if you have a GM 2.0 turbo engine.

[@Demosvibes]

David James yeah you're right I pick up wrong word. Yes I'm using Dexos 1 Castrol Edge 5w30 with Titanium technology

[@JRCW892]

@@davidjames666 My Opel Astra K has a gasoline engine (1.4 T 150 hp - B14XFT) and the users manual says Dexos 2... It's just that since March 2017, GM prohibited the use of Dexos 2 for small gasoline turbocharged engines because of LSPI risks. Now those engines have to get back to Dexos 1 gen2. But for atmospheric gasoline engines, I don't see any problems using Dexos 2 ! No LSPI risk !

[@stevefrench8256]

So many customers love it when i tell them we cannot put the cheap oil in their engine

[@millibarman]

Why is Mobil 1 0W-20 DEXOS compliant, but Mobil 1 0W-20 ‘High Mileage’ is not. So, what’s the priority; DEXOS cert and all that implies or the High Mileage additives that protect old seals? Would love to understand what’s most important. Thanks.

[@addicz2]

An own standard for their own bad quality products. Oll good ACEA A/B still superior.

[@marckemp9955]

Dexos1 gen 1, 2, and 3. Makes a difference. If you have a late model dexos1 gen 2 or 3 you better look up GM and find out what oils meet the spec and what oils don't. I was surprised there weren't any Valvoline conventional or blends that meet the specs. I don't really care for Valvoline conventional. I've never bought a car that had been serviced with Valvoline that didn't have a lot of upper valve train noise. Friend with a Jeep liberty used Valvoline and by 100,000 miles was seeing the oil light. He said it was always full. I told him to switch to synthetic and he did and then he stopped seeing the oil light flickering. Valvoline synthetic is good stuff but I wouldn't use anything less in formerly Ashland oil DBA Valvoline and now Aramco owned. Noack, HTHS, 100c test, 40c test, CCS and MRV usually tell what I want to know pretty quickly. The chemicals in oil like boron could actually be either a dispersant (keeps soot from clinging to the engine and keeps it in solution) or it could be an antiwear agent. Just depends on the chemical formula. Calcium could be a detergent and could be antiwear. Moly is a great EP agent but it's also why some oils turn black or darker quicker... doesn't mean the oil is excessively dirty. Less zddp is not good. More zddp can be just as detrimental depending on the engine. Flat cam needs more zddp. Roller cam doesn't need as much. I ceased believing oil labels and claims years ago. It's all in how they word things. 6x better wear protection might not be as big a deal as you think. 1.4x cleaner might not be as clean as 45% cleaner. Biggest thing is don't believe you know more than the engine engineer's and the oil engineer's. Because you don't. Nope, wasn't because they had wear in the valve train. It was dirt, carbon, soot. I'd find some Castrol GTX oil and some Rislone and do short changes until it stopped making noise and then just use an oil that some people with less objectivity loved to hate. I know this so much better than most. There's just no way to explain it to people who lack objectivity. It's like everything else I try to explain. Waste of my time to try to teach or reach them but for everyone else that's why I keep teaching.

My car is a 13 Impala and the manual says Dexos1, if I use the Dexos1 gen 2 is that good?

[@PetroleumServiceCompany]

Hello Stephen, you should be good to go as Dexos1 gen2 is compatible with the gen1 version. Let us know if you have any other questions!

[@davidjames666]

Stephen Hornak it'll be a good move. I use the mobile1 full synthetic that has the "dexos1 generation2" label on the box.

[@davidjames666]

Petroleum Service Company - PSC @4:30 there is a formal GM dexos1 gen2 discussion on KZbin. It's mentioned that the gen2 was partly developed for a specific drive pattern in a specific GM turbo engine to eliminate particle buildup internally to the turbo system, and additionally there is a slight increase in fuel economy.

[@falcon81701]

Can you use a Dexos 2 oil in a GM engine that specifies Dexos 1?

[@JRCW892]

Since March 2017, Dexos 2 (based on ACEA C3) is no longer allowed for small gasoline turbocharged engines because of LSPI problems. Those engines MUST use Dexos 1 gen2. But if you have an atmospheric gasoline engine or a diesel engine, you can keep using Dexos 2. If you use Dexos 2 or ACEA C3 in a small turbocharged gasoline engine you can get severe damage because of LSPI.

[@NorthlanderMN]

Of course it’s newer and better.

[@carvalho1990]

​@@JRCW892 Good to know, I have a GM small gasoline turbocharged car, and I thought of using this Dexos 2, but I'll stick with Dexos 1... following the manual specification.

Your engine oil must be synthetic because it recommends 5W-20 or also 0W-20. I have the same vehicle with the 2.5L engine. Only synthetic oils can be made at the 5W-20 and 0W-20 viscosity. Also, the oil should say Dexos on it somewhere.

The GM dexos spec is merely a year or so ahead of the oil industry’s new GF-5 oil spec. GF-5 will replace GF-4. These specs are developed by the International Lubricants Standardization and Approval Committee (ILSAC) with input from automakers, oil refiners and additive makers.
