Martin -- maybe not regular (AKI = 85 minimum), but the mid-level grade (AKI = 87 minimum) should generally be OK in all the sub 9:1 CR F engines. Search on "RON MON pump" (all words, complete words only) and you should get the two previous discussions on the subject (that have some useful outside links too).
(Premium won't hurt a 308, but you'll be paying for something it doesn't really need IMO.) |

The 308 should not get Super (Premium in the US). Wasn't that the case? It should get Regular? |

i trade oil and can offer the following:
the smaller refiners make a better grade generally since they don't have huge cat crackers that spew out lower grade material that needs to be stuffed into the downstream.
of the major refiners, exxon has a slightly better track record for keeping their supply above average spec.
and here is the downer for most of you....due to the fungible pipeline and terminal systems that deliver the product to the racks where the delivery trucks pick it up to take to the stations, the actual molecules all get mixed in together. so that by the time the material arrives at the station, you are getting alphabet soup with no defineable source. only in areas where the rack system is loading straight out of the refinery (houston for example), can you actually say that the material is from the same source as the name on the pump.
if you are in europe, then esso and total are usually the best picks. esso for consistent quality and total for mileage (a little heavier due to crude slate).

My choise is Mobile Super for all my cars . The 89 volvo (plain old 4 cyl.)has 205K on the clock and never touched the injectors as for the XJS with the 350 TPI only super. So its only natural that the 308 gets the same stuff. |

Guys I hate to tell you something, but if the place you buy your gas is an independant retailer, your fuel may not be what you think. One of my familys buisiness is a garage/gas station which is a Citgo..which was a Mobil before that and an Exxon before that. The same tanker from the depot always brought the fuel...sometimes the supreme was Chevron, or Exxon, sometimes it was Mobil or Amoco. I was told the main supplier was at the same depot. Notice the colors of the red, white and blue...Mobil, Amoco, Chevron and Exxon. The Citgo label always delivered Citgo grade on the premiums and other labels on the lower octanes on occasion. Techron is a good additive, it is only available in the premium, but all brands of the premium grade fuels have additives for octane and cleaning agents for your engine. I personally use Amoco Ultimate. |

Ferrari petition update.
Rumor is that the petitions 9628 and 9630 were a go. Now there is a stay of execution from a law firm in TX. Go to dms.dot.gov/search |

Chevron came out with Techron before anyone else had any additives that would keep injectors clean. Before gasolines were required to add chemicals to clean injectors and intake valves we had a hell of a time with EFI engines clogging injectors and intake valves carboning up caustng cold stalling and hesitation. This problem has gone away with more modern fuels yet many repair outlets still push injector cleaning which is about as worthless as charging your lightning rods. Injector cleaning was a big help years ago but not anymore. ALL fuels are better now yet you can still purchase Techron over the counter and add it to your fuel if you want and feel it is necessary. |

Regarding Chevron with "Techron", what is this magical stuff? And why do most people always tag on, "with Techron"? Can you order up Chevron gas and have them hold the Techron? Can I buy Mobil and ask them to add Techron? Or is Techron a proprietary formula only available with Chevron? If Mobil started adding Chrodil, I'd definitely buy it... "Mobil with Chrodil".
Chevron's marketing folks deserve credit. Every gasoline contains detergents. It certainly appears the reason Chevron stands out is because of that darn Techron! If Chevron didn't have Techron, would you buy your gasoline elsewhere? Techron must be the "TIDE" of the gasoline industry. Maybe TIDE has Techron... but they just don't advertise it?
I have a "Chevron with Techron" station down the street from me. I try to buy Shell when I can. |

Like Edward, I use the cheapest gas I can find. No problems in any of my vehicles. I use premium in my Mustang because of the advanced timing I have it set for (14* BTDC). I have used premium in the 308 because that is what the dealer reccomended. I will try a lower grade when I get it back from the service and see if it pings. |

I fill up at Citgo. They are closest. My other cars get Marathon. Cheap gas. I don't care for the brand. Amoco and Mobil is so much more expensive. I only use Mobil on the Jeep because it is close to my warehouse and that is where I mainly take the Jeep. They are the cheapest in the neighborhood there and gives me 2% off on AMEX.
Who said I am a cheap bastard? |

The octane you need is wholly a result of your compression; higher compression needs higher octane. You should always use the lowest octane you can that does not induce knock. I imagine different Ferrari engines have different compression ratios, so just read your owner's manuel and use what it says to use. |

I only put Amoco Ultimate 93 in the Ferrari and my VR6 GTI. Its perfectly clear, while 90% of the other fuels available is yellow in color, to me that means less crap in my engine. |

I almost always use shell. There are no Chevrons around me. I always put in 93 octane. Do you guys feel this is a waste? |

A recent ad claims that Chevron (with Techron) is what most manufacturers use to past the stringent 50,000 mile EPA certification cycle. That's good enough for me--plus, Chevron is easy to find here. |

I saw a study some time ago that rated gasolines and put Chevron with Techron above the pack (superior cleaning). Since then, I mostly use Chevron in all my sportscars, with occasional use of Shell.

I think any major brand is fine. I use mid grade since 308's don't have much compression and car runs great (85QV and 89GTB)

Shell for the most part, they sponsor them so I do, no other reason than that. Sometimes Mobil, but nothing other than those two. |

A question thats been on my mind sense I bought my 1984 308 GTS QV what brand of gasoline do most Ferrari owners use, should a car always use same brand and will it be better for automobile?
I started using Mobil and have continued. |
