A few weeks ago my brother and I took a 2500 mile round trip to Texas.

My bike usually doesn't make it west of the Mississippi and is tuned to run on 93 octane pump gas. This turned out to be a bit of an issue out west.

Starting in St. Louis, I found it hard to get 93 octane fuel that is commonly available in the mid West. The best fuel I could find was 91 octane, then in Texas that was hard to find. With the lower octane available and the mid West tune I had for 93 octane gas, I developed some mild preignition issues (pinging) under certain load conditions.

Lucas Octane Boost was recommended after a quick call to my engine builder, however this wasn't available to me. What I did find was LHP octane boost that was carried at most Harley dealers west of the Mississippi.

I can tell you, this stuff works and solved my pinging problem. I was skeptical as most of the octane boost stuff has usually been the equivalent of snake oil to me.

If you're in a pinch with some lower quality gas, this stuff helps.
