According to a newsletter from

when trailer towing (or anytime under a heavier than usual load), a higher grade of fuel will actually help mileage. Reason is that any pinging sensed by the knock sensors will cause a retard of the timing or mixture enrichment. This was part of the newsletter touting the digital dashboard enhancements that run on a PDA with the autotap software. The virtual gauges could show fuel trims and spark advance in near real time. One of these days I have to play with that a bit.
Other than that, I use a can of injector cleaner every couple of months and run regular gas (includes 10% ethanol here in NY). So far, so good.

Interesting that you mention that about Shell. It is one of the least expensive fuels in this area. I tried it a few times and would guess that I got between 10 to 20% less mileage on a tank than the BP that I usually use. I don't recall the lw300 saw any difference in power. Then again I bought the Shell when gas was near $4/gallon last year and it was all about the mpg and not even trying for power...feather-footed on the pedal and all that.
