Volvohead - What about in MT's asking for Dexron III?




Folks on the 'Vette forums have been swapping it out for Dex III with improved results. I'm sure there will be exceptions, but it seems to be getting all positive reviews so far.
 
I'm a bit cornfused. Didn't GM issue a bulletin about using Dex VI in MT's??? (I got some bad brain waste)

Not to my knowledge. There are guys out there using it in their C6 Corvette MTs. But I'm not a GM guy and will be using it in ATXs
 
Well I confirmed it today that most of the GM DexronVI sold in bottles is made by ExxonMobil.......so in 3 weeks it will be group I...
 
Hi TeeDubb,
Sorry to be picky but you might want to know that the GM oxidation test is now termed the GMOT. It's a 4L60E transmission driven by an electric motor at a transmission temperature of 163C (I don't know where that came from!).
The details are in the GM spec 10060 and there is some information on the SWRI website. However, you are correct and if you take a look at the spec the test is longer (as in IIIG) but the limits are even tighter.

I thought Petro-Canada was GM's supplier. When did this vendor change happen? Well, at least XOM has plenty of experience with Group III.
 
Vendors change regularly. Sometimes multiple vendors are used to keep up with demand. Not sure how many GM plants there are, but I wouldn't be surprised if different suppliers exist for different plants or areas. I also wouldn't be surprised if quarts, barrels, jugs...have different suppliers.

Dexron VI has been spec'd and licensed. Now its time for the oil companies to compete for those OEM contracts. We all know that those domestic automakers need all the help they can get in lowering costs!

Petro Canada makes all the factory fill and had the first license. But they probably don't have enough capacity because we got sevral cases today from XOM. Same package black bottle w/blue label. We couldn't get the usual 30gal drum yet.

I think I'll just get the 55gal drum and mount it in the bed of my truck...run the cooler lines in there and use it for a giant oil cooler.....what do you think the OCI would be for that? LOL!
 
So have any tests been run on the XOM stuff? Seems strange that XOM's Dex VI fluid would outperform their own premier product.
 
I think that what you have 'discovered' is what most of the oil industry already knows. The service fill supply can vary because all companies' qualified fluids that meet the spec are therefore allowed to tender.
 
I already well understood that reality. What I didn't know were the limitations on Petro-Canada's delivery capacity.
 
I don't know that we can conclude that it's a supply limitation issue. It may be that the buyers have greater scope to multiple source for service fill fluid.
