Was reading something a while back in which there was mention of go-karts and the fact that the ruling body had made it illegal to add diesel to the petrol engines in karts because it boosted the octane rating and thereby made the engines more powerful than the regulations allowed. I think it was only a very small amount per tankful. The thread discussing premium and regular unleaded petrol brought it to mind. Just wondering if anyone has tried it in a regular car and if so what was the result?

Diesel has really low octane rating compared to petrol, but has a higher cetane and energy content.

This is an old trick use in race cars for years and is now banned. I tried it once on a dyno and id did make a difference of about 2% from memory. We were trying different fuels when cams banned avgas.Never actually raced with it but it was an interesting experiment.Comment

We played with Toluene and Avgas back in the day but the AKA got more stringent with fuel testing so we stopped. We found the difference to be minimal with the small blending we did, but you couldn't exactly have straight avgas running you would smell it and obviously be under scrutiny.Comment

Methylbenzine used to go pretty well...
