My tow tunes are 93. I also run a 93 perf tune on summer blend as a daily driver. I have an 89 daily driver tune which I use with winter blend. When towing in winter, I try to time an empty tank and then run several gallons of 93-octane for the tow.
During the winter months I don't tow often at all, maybe once a month for ~100 miles RT.
Does this sound like an OK strategy?
The custom tunes likely explain the fuel dilution. They are probably conservatively rich, which is usually the case for a performance tune. You may need to shorten up your change intervals to compensate for that, in which case running an expensive synthetic makes less sense.
Were your tunes custom made for you or are they canned?
It would be interesting to see a run with the programmer out of the equation on the same oil at the same interval to see the difference.
