    Any chance you can expand on the below paragraph?
    "And with the thinner oils being introduced this year and over the next several model years—allowing better fuel economy and good high-heat protection—they counterintuitively place engines under higher stress in cold starts."

    "zero-weight"
    Ugh. It's not "zero-weight".

    Thinner oils cause more engine stress under cold start? Say what?

  • Gordon S. Posted: 3/4/2011 9:15am PST

    Bengt- Care to comment on thinner oils placing engines under higher stress upon cold-start? This is indeed counter-intuitive. Most informed enthusiasts I know think thin oils are better on cold start because they reach the valve-train sooner. What is the mechanism of stress? Where did this information come from?
    -Thanks

    My 2005 Prius lacks the temperature gauge and has no such light. This is only one of several dash-related annoyances. (It lacks indication of 10ths of a mile. The bar system for gas leaves room for guesswork and doesn't even register gas refills if less than 3 gallons.)

  • DAW Posted: 3/2/2011 12:04am PST

    Oil and water temperature gauges are missing since some time but my new car doesn't have a dipstick so I have to trust the info system of the car and that is just resetting my mindset on wanting to check oil levels myself every 6000 miles.

  • Marc Posted: 3/1/2011 5:43pm PST

    Replacing gauges with light indicators is a good idea although a combination would have been better. Most drivers overlook their conventional temp gauges and an extended overheat leads to many cylinder head and engine overhauls in the shops.

    I want to buy an auto that has a full set of gages .......does anyone know which sedan and truck that has a full set of gages?

  • Matt Posted: 3/1/2011 1:34pm PST

    I have a 20 year Mazda miata. Great car with a strong enthusiast community. Miata's of this vintage have motors that last about forever, unless you overheat them. At this vintage, hoses, radiators, thermostats can go bad silently, registering a problem only on the temp gauge. The factory temp gauge isn't great because it doesn't show warm until there is a serious overheat condition, but at least there is a gauge so people can turn off the car before blowing the headgasket and warping the head. In a nutshell, removing temp gauges won't matter much when the cars are new, but when the cars are older, the tools won't be there to prevent disaster.

    @al, I don't think this is such a dumb move from the manufacturer's perspective. The real money saved here is going to be through fewer major engine warranty claims (from over-revving when cold), not from the gauge itself.
    @alan, Agreed. As cars age, you can save repair expenses and unexpected failures by watching for temp-gauge fluctuations/irregularities.
    and @the cajun, Thanks for the catch.

  • Al Posted: 3/1/2011 10:08am PST

    Quit giving these manuf. a pass on every dumb move they make to "simplify." "Nothing to do with cost cutting?" you must really be naive. Don't need instrumentation? Of course not, when 50% of drivers don't pay attention anyway.
    Let's just keep dumbing it down folks. Next thing the dash will look like my old Cushman's.

  • the cajun Posted: 3/1/2011 9:58am PST

    "For the truth here, look at nearly any vehicle owner's manual; most advise against not revving an engine too high when cold, for good reason." If they advise AGAINST NOT REVVING, then they advise FOR REVVING.

    Guages are better than just lights; if some drivers can understand a guage they shouldn't drive. I had a family member drive 50 miles with a guage at the top of the red zone and runined the engine; when I asked why she didn't stop she said she didn't want to be late to a dinner with her girlfriends. I have driven stickshift cars without a tach but a temp guage is vital.

  • IndyRN Posted: 3/1/2011 9:23am PST

    I once had a 1986 Mazda RX-7 with BOTH lights and gauges and buzzers, in fact. I liked that system but I understand that there IS Cost Cutting going on. My 2009 Mazda 3 still has gauges. Guess I'll go with whatever they offer. I'm not going to give up on a car manufacturer because they offer lights instead of gauges.

  • Alan Lapides Posted: 3/1/2011 9:20am PST

    Temp guage needed. Not so much for cold but to see trend of Temp climbing - out of normal range that is usually in as an indication of onset of a overheat problem. Turn off Air etc/increase Idle speed in stop / go or worst case turn on heater to get add cooling. Knowing of impending issues can go a long way to helping to eleviate a problem

    how about:
    Why Does My New Car Not Have A Temp Gauge?

  • Damien Posted: 3/1/2011 8:57am PST

    As far as tachometers go, most everyday drivers have an automatic, and can physically hear how hard an engine is working, eliminating the need for a tach anyway.

  • larry300 avatar larry300 Posted: 2/28/2011 7:42pm PST

    Not to mention the battery gauge has been omitted from most vehicles these days.
    Next thing you know, only sport cars will have tachometers; replaced by leaves, feathers or something else ridiculous.
