When I'm in the areas of a known B20, I spend the extra effort to stop and fill.
Always dramatically quieter when pulling away.

I use Opti-lube myself. The thing that sucks is I have to have family in Florida send it up to me here in Canada.

I think I'm going to try some Opti-lube since so many of you guys seem to like it. I see most guys run the XDP, has anybody tried their Boost formula that has the maximum cetane? Just wondering if there's any fuel mileage/lubricity benefit over the XDP. Plus it treats a lot more fuel (which may mean it doesn't work as well).

The Opti Boost doesn't do much for a lubricity improvement but is the most cetane boost. I did not see any improvement in mpg myself.

I run the Opti Summer and Winter versions personally.

If you are expecting to see spectacular results by running one additive over the other, you probably won't.

Opti-Lube with BetterDiesel FBC at every fill. Bio-diesel is hit or miss. Most of the time you never know exactly what percentage bio is actually in the fuel. If it says B20 the fine print lets you know that it can be "up to 20% bio" which means it may be 5%.
