Is there a difference in what type of gas you use for your Disco? I have a 98 Disco w/101k miles on it and use Super (93). My commute to work is short (2 miles round trip) and I drive to Vermont almost every weekend from Boston (Skiing). So would I notice a difference if I started using the cheapo? |

i use 87 in my 96 w/116k miles (indicated) and have been doing so since i got my disco with 30k miles on it. i treat the gas every now and then to the Lucas addatives. |

i used exclusively high octane in my disco after doing some experimenting with fuel consumption records.. the 93 oct gas provided slightly better mileage , just enough that it paid for the extra expense at the pump. so i went with it figuring it cant be worse for the engine.
this spring i got my tit in a ringer while traveling through B.F. colorado and had to fill up with 85 octane and proceeded to drive the most mountainous region of my trip with this gas. a side from being pitifully slow i had no engine sputtering or notable performance characteristics. |

Mine knocks pretty bad w/ anything but 93. Apparently it just depends on the truck but it seems like most of them don't get along well w/ lower octanes. |

The distributorless engines have knock sensors which will just retard the ignition timing. Retarded timing will create less torque.
Using regular gas may be a contributing factor as to why American Discovery's are having exhaust valve problems. The fuel and ignition systems are preprogramed for premium fuel. If you use regular gas the combustion process is faster and hotter than engine managment system was designed to run.

yeah, i had a 1997 supposedly it adjusts to the low octane gass.

Well... I've used only 91 or higher in my 1999 D2 and had valve problems. Also changed oil every 3k miles. Go figure. |

I've had the same experience as Pokerob. It works but it becomes even more gutless and sucks more fuel when running on the lower octane (87) stuff.
So what I do is use the midgrade when prices are really high and I use the premium stuff otherwise. |

Hey Rob!
ALL Rovers are pitifully slow here in Colorado. The only nice part is the scenery is great here in BF and were not in any hurry so there is plenty of time to look around. BTW I spoke to the head mechanic at LRGS and he says what you need to hop up your RRC isn't octane it just needs a bit more cowbell. Cheers, |

Sean,
I'll second that. I'm at 9100 feet in BF Colorado (closest Wal-Mart is 45 minutes away). Unless you have an F-250 Super Duty turbo diesel, Audi, Porsche, etc., you aren't going anywhere fast, no matter what you drive. Especially if it has a 60's Buick engine. I drove a '03 Disco with the 4.6 for a couple of days, and it was just marginally better than the 4.0. But with all the snow we have, most anyone going fast ends up in a ditch, or worse. I always buy the highest octane available, at this altitude every little bit helps.

Forced Induction rules. :-) My first trip to Colorado was in my "then new to me" 1984 Audi 4000quattro. We went to the Pikes Peak Hill Climb with about 30 other Audi's.
Great trip. But man, I really learned the advantages of a turbo at high altitude. Even going from Sea Level to 2,500ft (old home, parents house in Spokane) I notice a big difference in the Disco. In my 4000 (same one but now with a Turbo Engine in it :-) And about twice the power :-) I get the same power but a little more turbo lag.
Anyhow, every time I go to my buddy's Audi Tuning shop I cant help but wonder what a couple K04 turbo bolted to some custom exhaust manifolds would be like. :-) Just run about 8psi or so through some factory S4 Intercoolers and youd be fine. I dont know but you'd probably have over 250hp, without a lot of the problems associated with the Supercharger conversions (HEAT)
Hmmmm. Now a twin turbo 4.6 with custom pistons running more boost, now that would be fun.
Oh yea, I run MID octane in the Rover in winter. IN summer I tow a lot and it gets hot so I run High Octane as towing the boat on a HOt day I'll get some Pinging.
The turbo Audi's HATES low octane and only gets High. And even some Toluene mixed in when I feel like cranking the boost up a little to dispose of all those pesky mustangs and Camaro's. :-)

all i can say about the speed of the disco was, 235/85 tires (stock gears) in full expedition mode with a riduculous amount of excess weight, and as unaerodynamic as i could make the thing.
85 octane and about 1500 miles of constant moving. i was able to rocket up the mountain at 45 miles per hour and still felt all fucked up. it was the oddest thing but going up that mountain _felt_ like i was going downhill, but i was going up according to the GPS, and i kept slowing down... seems i was letting off the gas expecting to coast, very freaky.
for the record i am exploring a way to mount a cowbell onto my RR dash, just in case bruce dickenson ever needs a ride.
where is LRGS anyway?

Hey Jack!
What part of BF are you in? Were at 9100 ft as well and the nearest Wally world is an hour. A town of 600 folks called Florissant. I see you have a Ski/ Bike shop somewhere. That sounds like my life.
Rob,
I'm mounting the cowbell to the D90 this weekend. I have two and just can't decide on which one. Do you think John at RTE or Matt at RW would make us some mounts? |

i 'd try kyle's venture: www.roversolutions.com i think this is right up his alley.

Sean,
I'm in Winter Park, pop. 523. But, since we are a tourist town it seems like much more, especially around Christmas through New Year's. The valley here is starting to grow, but still fairly rural and very laid-back. Right now we're in ski shop mode, and will set up the bike shop in May. Winter Park / Fraser Valley will be on ABC World News Tonight w/ Peter Jennings tomorrow evening, Wednesday Jan. 8th. They're doing a story on the local school system, which has a 4-day school week and recently tested at the top of Colorado school districts. Where is the closest "big" city to you?

Jack,
We are an hour west of Colorado Springs. We have spent a ton of time in WP and Fraser and love the place for mountain biking. Did the Tiperary Creek race a few times. Not too many good days at WP/MJ but we didn't have any one to show us the stashes. What is the name of the shop? Next time we are in town we'll stop in and say hello. |

I just put 87 in for the first time since I have owned it. Mainly because I am short on cash until the 15th. I'll let you know if I have anything strange happen. |

Sean,
I'm partners in The Viking Lodge & Ski Shop, on the left as you enter town of WP. I've ridden Tipperary quite a bit and done the point to point race as well. In the summer, I ride every day and in winter, try to ski when I can. Shoot me an email when you're headed this way. Lots of good 4x4 trails around here too.

I use 89 all the time in my 98. try a k and n filter you gain some mpg too. I was getting 12mpg now 14 to 16 on good day. |
