Scrappy Chemistry 0.6.0 features Remix mode, which is a new take on the mod's mechanics and includes substantial revisions to many of the recipes. We are rather fond of how it plays and encourage you to try it out, but if you've built a base on the standard mechanics and don't want to have to rework everything, there is a setting that allows you to return to the old recipes from 0.5.

As of 0.6.4, the oil processing recipes in Remix mode have had their speed doubled, from 5s to 2.5s. We decided to do this due to the greater amount of petrochemistry infrastructure required in Remix mode: you need to handle tar, separate naphtha, sweeten sour gas, synthesize petroleum gas from methane, and so on, so not having to have so many refineries seemed like it easier to focus on the interesting logistics rather than just copy-pasting refineries. However, there is a setting, if you prefer the slower recipes.
