Is there a Dexos Full Synthetic?

[Knightfall]

I called the dealer and they reaffirmed that they only stock full synthetic Dexos. I guess I'll trust them. I only really cared because I plan on driving about 4000 miles in the next month. They are also going to rotate my tires tomorrow.

While GM is indeed moving to second generation dexos1, that spec doesn't become the dexos1 standard until September, in line with the 2018 vehicle lineup. And for anything pre-2018, the original dexos1 is all that is required. As a side note, many full synthetic dexos1 gen 1 oils already meet or beat the gen 2 standard. Gen 2 is coinciding with the new ILSAC GF-6 standard that is due to come out in the fall. Both of these standards are pretty close. Same is true of ILSAC GF-5 and dexos1 gen 1. That is why I just never waste a lot of time worrying about if the oil I am using is approved by GM or not. As long as it meets the current API-SN and ILSAC GF-5 specs, I am comfortable with it. Heck, my 2006 Cadillac CTS called for M1 5w30 synthetic with 6094M spec and all I give it is Pennzoil 10w30 conventional with 6094M spec along with API SN and ILSAC GF-5. Still runs great and since car in fantastic shape, we will keep it for a lot longer.

It was in a different jug with a diferent label for Canada. It said 'synthetic, but can't recall if it said full synthetic. I was a bit distracted by the price, which was 62.00 Cdn.

Yikes....yeah I would not have looked long at it either at that price.

GM announced a Dexos change back in June 2016. Gen 1 Dexos is the synthetic blend. GM has now moved on to Dexos Gen 2 which is full synthetic. This is in regards to the upcoming ILSAC GF-6 oil specs for 2018. Gen 2 Dexos is a GF-6 oil. Improvements made are for small displacement high boost engines (like the 1.4, 1.6 and 2.0 Ecotec turbo engines, etc.), better timing chain wear protection and much better fuel dilution protection due to GDI engine fuel contamination.

 

More than likely every GM dealer in the nation has been switched to Dexos 1 gen 2 oils.

 

And yes as others said, Dexos is GM's name for their oil requirement. We (GM dealer) use AC Delco Dexos bulk oil 5w30 and 0w20, both Dexos Gen 2 oils.

 

This link shows all the Gen 2 licensed oils on the market: http://www.centerforqa.com/dexos-brand2015/

 

This is the Gen 1 licensed oils on the market. These licenses expire Sept. 1st this year: http://www.centerforqa.com/dexos-brand1/

 

 

Does this mean GM dealers are now required to use Gen 2 (full synthetic) for oil changes on previous model years (my 2017) or only current?

 

If the Gen 1 licenses expire on Sep 1st, I assume that dealers would no longer be able to purchase it at all, making all oil chances full synthetic?

 

I wonder how this is going to effect the cost of an oil change? I am still trying to figure out if I am going to start doing my own oil changes after I use my free ones.

No change in cost really to the dealers. Stayed within 40-60 cents per gallon to them. GM dealers buying from the GM oil program should almost all have been switched by now for sure.

Lots of good choices for Dexos approved oils. For gasoline engines your spec is Dexos1. Dexos2 is for diesel applications. The confusion may be that the new gen2 Dexos certification is a revision to the original spec, and takes effect 9.1.17. This is called gen2 (as opposed to Dexos2). So what you are looking for are Dexos 1 oils that meet the gen 2 (new) spec. The current list is in flux as new oils are coming online to the spec before the fall deadline. Example: as of today 6/30 Mobil 1 only has 5W-30 on the list. I expect their other weights to easily meet the spec, but not yet officially.

 

Just looked at it this morning. http://www.centerforqa.com/dexos-brand2015/

Pretty much all the majors are on the list. Mobil, Pennzoil, Quaker State, Castrol, Valvoline, Havoline

 

Since oil brands are a lot like trucks; some people swear by certain ones and swear at others, this is for any Valvoline guys. I noticed that NAPA synthetics are now on the gen2 list. For all intents and purposes when you buy NAPA synthetic oil you are basically buying Valvoline Synpower. Usually NAPA puts this oil on sale for $2.99-$3.99 quart about 3-4 times a year. NAPA syn is a great choice at a great price.

Just a nod to the cost conscious.

Yeah, I would guess they would keep just dexos1 Gen 2 as part of their bulk oil store to cover everything. Wouldn't make a lot of sense to stock both Gen1 and Gen2 oils. That being said, a 2017 or older would not be required to use Gen2. I am not changing anything. I will use the same oil I have been using in both my 2013 1500 and my 2015 2500. And it isn't even on the dexos1 Gen1 or Gen2 list.

I noticed mobile 1 was using a cheap filter on mine. God knows what oil is in that container. I know buy my own oil and filter and take it to them to change. I do this to retain my warranty. They charge 20.00 using my own oil and filter. So basically I'm paying 20 to get it reported that my oil is being changed
