>but diesel fuel has a very high octane rating in comparison with gasoline,
"octane" is the ability of a fuel to "resist combustion" from compression. Diesel fuel is not rated in "octane" but the opposite: the ability for it to combust from compression. For some reason in the "old days", it was commonly thought by some that by adding some diesel to gasoline that it would help "lubricate" the motor (as diesel does have an oily feel). However mixing diesel with gasoline only lowers its octane rating.
- erdos4d 6y agoYeah, I am not sure if octane is the right word here, you are probably right in what you say. I just know that diesel fuel is much more resistant to detonation at high compression ratios, given how a diesel works. In a gas motor, octane gives a measure of this, so I used the word there, but as you say it is probably not the right word.
