I think a 5 gallon pail at our local TSC is about $10 cheaper than the equivalent volume of our Mahindra oil. The difference being about $0.50/quart. We sell ours in gallon and two gallon jugs at the same per qt rate as a 5 gallon pail, and they are certainly easier to pour from than a 5 gallon. Or at least lighter, which equals easier in my mind. So you could buy two 2 gallon jugs and one 1 gallon jug for about $10 more than a 5 gallon pail from TSC.
I think most dealer branded oils will be a little more than a good non-branded oil. But it is not ridiculously more. I don't care what brand folks use as long as they use quality oil. We all know that Mahindra does not make their own oil and I am not some sort of OEM oil snob. Just use good oil.
