Volvo S80

    No, I doubt that something "tuned for regular" would be the worse for higher octane blend. Actually , lower octane motor fuels burn with greater flash front speeds than higher octane fuels. They may also have greater net (delta H)heat content because of the isomers in lower grade fuels are more exothermic. Recall what raises octane, benzenes and toluenes, which have less energy content than the base stock isomeric mix. So, these considerations can sometimes result in greater power output from lower octane fuels. If the engine requires substantial timing advance to step up power levels, then one must use the slower burning higher octane to permit maximal timing advance. High compression may also lead to inaudible detonation which will trigger the knock sensor, retard timing, and detune spark advance. The best way is to conduct a dynomometer test and see what the system does.

    But it would be a rare surprise, to find an engine tuned for premium, that would deliver optimum performance on regular, don't you agree?

    My throttle vanished. I'm not sure it was varnished but the sensor went to the tune of $850. This at 50954 miles and 4 years and 1 month. It was also on a trip and cost another overnight. Has anyone had luck pushing Volvo on the warranty?

    Never hurts.

    Did you ever get an answer to the Sun Roof issue? Mine makes a mild wind noise now, I think it is the same problem.

  • Have a 2000 S80 2.9, 58K miles. FYI, only two problems: shake in steering column (a couple of failed fixes and finally fixed at 30K) and failure of cooling fan @ 40K (fixed).

    Original equipment tires finally worn out. Anyone have any suggestions on what has worked well. Someone suggested Bridgestone Potenzas in a much earlier post. Anyone tried anything else?

    Hello!!!! I own a 1999 S80 and keep getting a open fill cap light message, has anyone had this happen to them?
  • volvomaxvolvomax Posts: 5,274
    happens alot.
    First, ckeck the cap, make sure its not cracked or the seal is bad. If the caps ok, take the car to the dealer and have them check the fuel tank itself and the sensors.
    Sometimes it just a software glitch.
    The dealer should be able to re-program it.

    Davant, Just wondering which Volvo dealer you utilize. I am here in the Tampa Bay area and I have suffered with Volvo of Tampa Bay and Robert G Waters in Lakeland.

    I have never owned a Volvo and I have heard that the '99 and '00 S80s should be avoided ....any other things to know about the 2001s.....

    Any info on reliability or issues would be GREAT.....

  • nvbankernvbanker Posts: 7,285
    My business partner has an 01 with 70,000 miles. Only repairs have been Air Conditioning, a motor mount, and the famous, wiring harness issues. He counts it an excellent car.
  • I own 2000 S80 2.9 - 77K in 4 years and enjoy it tremendously.
    No major problems - a couple of bulbs, infamous sub frame bushing a noisy window motor in the driver's door.

    All has been fixed under the warranty, in very accommodating manner.

    The rest - is a pure enjoyment.
  • My 1999 has now had 2 transmissions in less than 2 years, one under warranty, the other cost me over $4000.00.

    Also had to replace rack and pinion on the car less than 40,000 miles out of warranty because of age. Volvo supposely redesigned the part(s) the original estimate $1500 turned into $2700.

    I have resently filed suit against Volvo and would like to hear from folks with similar experiences.

    I think those are GM transmission in the S-80, which is odd, but true. And, they rarely fail.
  • It's not too odd. GM transmissions were widly used on BMW in 90th.
  • nvbankernvbanker Posts: 7,285
    BMW transmissions were used in the 80's Peugeots too.
  • kiiwiikiiwii Posts: 283
    Wow, I didn't know BMW uses GM transmissions! That's news to me. Why? Does GM make good auto parts? How's the GM transmission that Volvo uses in the S80? Are there other major parts in the S80 made by domestic auto?

    Regarding my #1506, (gosh I can't believe somebody read all that) I'm about eight hours NW from you in Fort Walton Beach. Beal Parkway Volvo/Lincoln-Mercury is an outstanding dealership but minuscule compared to any in Tampa and I certainly don't think it's worth the trip unless you have family here. If this were Alabama that'd be a given as it seems they're all related...and are driving with handicapped license plates (redundant, IMHO), LOL. We have family in Daytona and car shopped there too. The tiny Daytona dealer recommended one in Orlando but I've forgotten the name. If you can stand the I-4 trek East maybe they offer a free Disney shuttle, best of luck.
