By now, I suspect that only ULSD is available at most on-road fuel stations.
That being the case, there are a few situations that present potential for choices.
1) use ULSD as is. It does get a lubricity additive, but there are times when some "improvement" might be a good thing. The ULSD found at the pumps is good enough to pass industry tests, but sometimes we BITOGERS prefer a bit more than the minimum. I doubt that it's detrimental to use pump ULSD, but some people simply like an extra margin of safety in their products.
2) use a commonly available full-feature diesel fuel treatment. These typically address cetane, moisture, cold-suppressant points, lubricity, etc. If you use one of these, I see zero need for any two-stroke oil to further the lubricity. This is my personal choice.
3) if you use ULSD and do not use a full-feature additive, then you can consider adding TC-W3. I has been shown in some tests to significantly make the lubricity "better". Just don't over-treat it; that's a waste and it's smokey. A few ounces per gallon are typically enough. As always, there is a balance between cost and benefit.
