Sausss edition, one of two special editions released in 1985, running on unleaded fuel. The other was the I fly bleifrei. |

Aren't engine and/or cylinderhead of the 2CV from aluminium? If the valve seat rings are from aluminium, any engine can run with unleaded fuel. |

Aluminium is a soft material and needs hardened inserts to make the valve seat. Link to "www.hthoward.co.uk" |

Yes, the valve seats were made from tempered steel. So probably running OK on unleaded anyway. In 1985-86 they gained even harder seats. A different issue was the deterioration of rubber (gaskets, hoses, even fuel pump). I had to remove my fuel jets and clean the interior of the carburetor quite often, even after adding a filter and replacing the fuel line with an updated rubber type made for unleaded. |

@tore-40: with what car? The K 70 (iron block, aluminium head) and all NSU-cars (alumnium engine) can have unleaded fuel without any changes. There were some NSU-owners, who changed the valve seats, but this is not neccessary. Of course there are also morons, who say "When you use unleaded fuel, your engine will burst immediately!" but this is bullshit. All blokes, who said that to me, hadn't used their classic car in unleaded times at all, so no own experience. I drove all my K 70 and the NSU 1200 C for hundreds of thousands kilometers always with unleaded fuel without any fuel-caused problems. The only lead-fuel my cars every had, were a few liters from the tanks of cars, we had wrecked. The only fuel-caused problem, I remember, I had with my dad's 1981 VW Passat (75 hp, 1,6 liter), when I filled DDR-fuel (the sludge for DDR-Mark for locals, not the Intertank-stuff for D-Mark for Westerners) in it. The engine ran as "a bag of nuts", as we say in German. It became immediately better, when it got filled up on the first gas station on the other side of the Iron Curtain. -- Last edit: 2019-03-17 22:33:48 |

tore-40, your troubles with rubber elements in fuel system may ignited because of m/ethanol additives for modern petrols, always over 5% today. |

All aluminium heads have hardened valve seats so there wont be any issues with unleaded fuel. A friend of mine have a Volvo 142 with the B20 engine with cast iron head. He thought it was unnecessary to use lead substitute in the gas. After some years the car would run worse and worse until it wouldn't start at all. He lifted the head and the valves had eaten away the material where the valve seat used to be! |

@ingo, that was a aged 1981 CX 2.0 with what is often called a Douvrin or PSA engine, not much iron there. (25 years ago - OMG) I seem to remember they were approved for unleaded from around the time when the Series 2 arrived. In retrospect, I think they would run fine on unleaded anyway, but we were recommended adding lead substitutes @130rapid, this was about 1995, I used to suspect my lead replacement additives were to blame, there were no eco-friendly additives mixed in by then like E5 of today? |

The American contributors to another blog I see all complain about ethanol added to the fuel there, and its effect upon rubber in the fuel systems, even in kit like chainsaws and generators. |

Interesting. When did they start polluting the petrol, in your opinion? |

Modern E5 & E10 unleaded is appalling stuff. It has a shelf life of about 2 months, after that it starts to evaporate and leaves a resin that no amount of solvent carb cleaner will shift, only ultrasonics will move it, most bikers now know to drain the carbs if parking up for more than a couple of weeks. Problem 2. It rots plastic, glassfibre and most rubber compounds (EPDM is safe, for the moment) so lots of classic bikes are having problems. Problem 3, It's hygroscopic so your steel fuel tank is now rusting from the inside out, especially problematic if your fuel tap isn't the lowest point of your tank. The shit you're paying over a fiver a gallon for isn't petrol! |

There is a lot of discussion about this in Hemmings. Apparently the powerful farming lobbies in USA have persuaded their government to insist that ethanol made from a maize type plant is inserted in increasing proportions into pump fuels. It is apparently still possible to buy ethanol free petrol but only from relatively few outlets and at a price, the boys in this blog get quite exercised about the effect on their old cars and bikes. If you go back far enough, there will not be such difficulty, buy a Model A Ford or a Chevrolet stovebolt six! https://www.hemmings.com/search-content/?q=Ethanol -- Last edit: 2019-03-18 08:58:56 |

Problem 4: the production of that "bio" or "organic" fuel is extremely pollutive for the environment, as destroying nature reserves Problem 5: the field, were "bio" fuel is growing, cannot be used for food production -- Last edit: 2019-03-18 10:18:11 |

Isn't that usually the way with "green" initiatives? All they do is move the point of pollution from one place to another. |
|

No, it's even worse: several "green" initiatives are even worse for the environment than the conventional way to handle that topic. |
