  1. Hello,

    Just purchased a 2005 MSM with 40K miles. What grade of Mobil 1 oil would you recommend for the AZ desert and SOLO? I was thinking of using 0W-40. Thanks.

  2. Hi All –
    I’m an ecstatic new opener if a ’97 STO that needs a new top. This car is my daily commuter car, so it’ll be all over town and parked in the sun all day. I’ve seen threads on other sites recommending Robbins tops but I’m looking for a local opinion: Should I replace the top with canvas or vinyl given our brutal desert summers?

  3. Need help. I have a 1993 mx5 automatic. The other day I had a loss of power as well a a continuous “bogging sound”. Now I can barely get the car to start it turns over for a long time before starting and runs rough. when I try to drive it I can barely get it to go 30 or 40 miles an hour because of the power loss. In the last 6 months I have replaced the fuel pump, fuel filter, ignition coils, plugs, and wires. Side note I kept the old ignition coil and plugged it back up to make sure the new one had not went bad. I also pull the timing cover to inspect the timing belt and make sure it had not sheered any teeth off or was damaged. Installed new plugs for good measure.
    Lastly 2 days before this happened I had to have a new battery installed.
    Any help would be greatly appreciated..

  4. I have a 2002 Miata with the clutch shudder issue. I was wondering if any one knows a good mechanic who is knowledgeable about miata’s and who could help me out with this.

    • Tucson Foreign Car and British Car are the most often recommended by members. You can find links for both on the resources tab under community.

  5. Finally need to replace my ’03-SE OEM Tires, sigh! Looking for suggestions on brand and sellers around Tucson. Checked Costco online but they don’t list (now) any Miata tires. Sam’s Club shows these: BFGoodrich G-Force Sport Comp-2 – 205/45ZR16/XL 87W? We use “M” car for “fair weather” pleasure drives around southern AZ and maybe a regional trip now & again. Appreciate your suggestions. Thx, Rob

    • Hi Rob, do you still own your 03SE? I just picked one up from a guy in green valley and am trying to get some history on the car. Any info would be appreciated! Matt

  6. I’m replying to myself. I figured it out!

    Looking for installation instructions for OEM Wind Deflector for 2006 MX-5 Touring.

      Disregard posting. The OEM wind blocker is simple to install. Pop old one off and new one on.


  10. Plastic rear window just ripped out of my 1995.
    Who can, or where can I get this re-sewn? In Tucson.
    Thanks. James

  11. RE: idle drop. My ’95 suffers from occasional idle drop. Is there a solution to that problem?

  12. My 1991 Miata runs very well with the exception of occasional engine ping. This has persisted in spite of the fact that I just installed new spark plugs and had Greulichs accomplish fuel injector, valve, and combustion chamber cleaning to eliminate any carbon build-up. I use chevron 91 octane gasoline, so the gasoline formulation should not be the culprit.

    Is there a remedy and a reliable service center in Tucson where I can eliminate the engine ping?

    Thanks for your time. Chris

    • If you check the Miata Resources pages, two local shops have been consistently recommended by members for service issues. Don’t think you can go wrong with either.

  13. Hey folks, not a member but just came upon your site (and then your FB page). I have a 1999 Miata and was wondering if anyone knew of a good way to get a replacement spare tire. I just had to use mine for the first time and while it worked fine out of the trunk, it crumbled fairly quickly, no doubt having dry rotted from many years in the AZ heat. I haven’t found any sources online for replacements except junk and salvage yards. Jim Click quoted a price of $200 plus tax, which seems mind-blowingly high (I could get two new regular tires installed for less than that). Would anyone happen to know anywhere in Tucson that would be a good place to check? Thank you very much in advance for any help anyone could give me!

  14. 1991 Miata. Anyone know of a shop in Tucson that will replace the plastic rear window. Called Diversified Auto, they did not seem to enthused about taking this on.

    I have a 2006 Miata Touring with only one key fob with the key inserted inside. I called Jim Click and they want $286 for the fob, $80 for the key that goes inside and $60 for programming. This is $426 plus tax! Has anyone found less expensive alternatives?

    Re: NC Fog Light Modification
    I completed the fog lamp conversion today (Jan 24, 2014)on my NC. The whole project, including resetting my radio stations took about 45 minutes. I worked slow rereading the instructions as I went.

    It is a tight work space down in the second try of relays that lie under the top tray of fuses and relays but just enough space to work with the wires. Normally, the fog lamp relay is energized from the headlight relay so that fog lamps work only when headlights are on. This mod changes the fog relay to energize with the taillight relay. The fog lamps now work independent of the headlights. I can run the fogs with the headlights if I choose. For now I will keep the fog lamps and not replace the H11-55W fog bulbs with LEDs until there is a burnout of a fog lamp bulb. Further, the fog lamps show well enough in the daytime as daylight driving lights. LEDs would be even better.

    Tires for your zoom-zoom
    Jan 25, 2014 – 4:41PM

    After many years Michelin started making tires for the MX5/Miata. COSTCO has them and even have a Michelin sale starting Jan. 30th where they give OFF $70 per 4.

    I checked for different years. They seem to have it for 2006 – 2012 only.

    We purchased 4 tires from them in October for about $650. It included the tax and installation and recycling of your old tires. It is a bargain. The rating on these tires are all 8 – 10 (10 is the best)

    You can order it online to be shipped to your local COSTCO which has an Auto department. When COSTCO shows that they delivered it to the local warehouse (free delivery) then you can just call the auto department near you and ask them to see if you need an appointment. (Most cases you do not)
    While you shop they will install the tires in 1 hour. Also get guaranty and life time tire change with it.

    Happy rolling,
