For those knowledgeable on fuels and additives, what have you added to your pump gas?
Personally, over the past 5 years, I’ve added toluene, xylene (as toluene was phased out from stores because of drug addicts), MMO, ATF, castor oil, and wintergreen oil. No ill effects, and the car runs pretty strong! My plugs always looks great, fuel rubbers are fine, and my OEM injectors were removed at 120k miles and sent off for cleaning and flow balance. All but one were basically perfect as received.
I don’t have any dyno runs to prove any power gains (since I have doubts on repeatability), but I do know the car is very strong from ¼ mile runs using my concoctions. A few years ago I started a thread documenting my ¼ mile runs if interested….
Since I don’t know of any Honda OBDI datalogging capability, I started doing trial-and-error tests bumping up octane to get some butt dyno impressions. Can you notice a decrease in engine performance if you’ve been forced to use 87 octane gas at some point (availability while doing a road trip or something)? I had to once and noticed a big drop in power from my butt dyno. That sent me on a quest to determine the optimum octane that would bump up to the limits of the OEM timing curves. I finally settled on a ~96 equivalent octane rating using toluene or xylene mixed with 93 octane pump gas.
I run it in 5 gallon batches, to which I add a little lubrication (an ounce of MMO, ATF, etc).
Furthermore, I really dislike the NOx and other exhaust byproducts and smell when bypassing my Magnaflow hi-flow cerametallic cat with my cutout, so I've been playing around with different fuel "scents." I guess after I hit 30YO that I no longer wanted to deal with annoying loud stinky exhausts all the time. Some folks like that musclecar and Harley exhaust stench, but I don’t really care for it in my old age.
The xylene alone gives the exhaust a "sweeter" smell (hmmm, probably why it's called an "aromatic"). MMO also contains a bit of wintergreen oil so it also contributes to a sweeter smell (some of this is attributable to the naptha and other ingredients in it). I just recently bought pure wintergreen oil to mix in as well. I add about 1/8 of an ounce to my 5 gallon mixture to sweeten even more. It’s a lot cheaper than using these aftermarket scents:

The end result is a fuel that makes full use of Honda’s OEM ECU capabilities, makes the engine run smoother, and also smells sweet when temporarily bypassing my cat for sound and power.
