When I was researching oils recently, I was suprised that few products actually list their exact ingredients. However, I also found that many will provide more information if you email to ask! I inquired about the DAC oil omega ratios, and here is a direct quote from their emailed response:
"The dac Oil has a 2:1 ratio of Omega 6 to 3 fatty acids (primarily ALA but some DHA as we include fish oil)
The dac Oil has 100% Natural Vitamin E"
They did not provide the actual amounts of omegas, or the total vitamin E content.
In my search, I also found out that CocoSoya has a 7:1 Omega 6:3 ratio :eek:, and that Equine Omega Complete (which claims to provide an “optimum balance of omega-3 and omega-6 fatty acids” is “currently in the process of getting their extended general analysis,” which is the same answer they gave me a few years ago 
If you are concerned about the omega ratios and want a cost effective option, Canola oil (2.5:1 Omega 6:3) seems like a good bet. Oils with superior Omega 3:6 ratios are generally flax or fish oil based, and can be significantly more expensive.
A moderate option is Animed’s FSO Blend, which is comparable in price to the CocoSoya and has an Omega 3:6 of about 1:0.75
