In the 01 Nov copy of Classic Car Weekly( I buy it for the horticulture section ) it was said that Mazda were running their heritage fleet on synthetic fuel.
Another story about running a MX-5 on synthetic fuel is here: https://wkk.usa.mybluehost.me/mazda-just-proved-that-synthetic-fuels-could-be-the-future/#:~:text=Mazda%20sourced%20its%20fuel%20from%20Coryton%2C%20a%20UK-based,into%20hydrocarbons%2C%20which%20serve%20as%20a%20gasoline%20substitute..
I guess Mazda are using Coryton fuel.
Is there any feedback from Mazda to the rotary community about any issues , upsides or downsides on running rotaries in their heritage fleet on synthetic fuel ??
