  1. G.A.Branigan Says:

    I’m really liking the all new JL Unlimited.

  2. Brett Cammack Says:

    Premium fuels usually have more detergent additives (from what I’ve read) and, therefore, it’s not a bad idea to run a tankful through the system a couple of times a year just to keep things clean of deposits.

  3. Kit Gerhart Says:

    #2 I’ve been using regular gas in my two “premium recommended but not required” cars, a 2010 MINI Cooper, and a 2016 Corvette. I make it a point to use “top tier” brands that, supposedly, have similar detergent additives in all grades, including regular.

  4. Bob Studee Says:

    John I’m a bit puzzled. jeeps have a terrible reliability rep, plus the “death wobble” situation. Is it just image that keep this car selling?

  5. Chuck Grenci Says:

    Regular and Premium (naming) are from a bygone era; the biggest difference is the octane so if you don’t need it (octane) don’t buy it. All gasolines are required to add a certain amount of detergents to their fuel, and while the minimum legally required may be slightly subpar, if you are re-fueling with a Top-tier brand, detergent/additives all must meet the toptier requirements (in order for that gasoline brand to earn the Top-tier rating.

  6. JWH Says:

    If the engine has a knock/ping detector system, the timing may be retarded when using lower octane fuel with adverse impact on HP & economy. Volvo V70R with turbo is premium required, while Corvette as Kit stated is premium advised, & Fusion 2.7 turbo only states regular. Will admit that with an estimated on-cost of $225 to $250 for premium, I’m being a sucker to obtain maximum performance. And I use top-tier fuel (Costco’s finest) >95% of the time.

  7. G.A.Branigan Says:

    @ #4: My last Jeep was a brand new 08 JK 2dr. Off road it was at home,on paved hwy it didn’t handle well. I experienced DW once,on the hwy doing 65mph. I forget how many miles I had on it,maybe 20k,that’s all.

    Reason for the DW was improper sized bolts on some of the front end components,and overall cheap suspension components.

    IF the new JL’s are built with better parts,it should make them very drivable/durable.I hope…

  8. Bradley Says:

    I have a 2014 Lexus that I bought used. It has 60k miles. It needs a new catalytic converter (which is covered under warranty).

    The dealer said its most likely because the prior owner put low grade fuel in the car regularly. In Iowa (where I live), Low grade fuel has a large concentration of Ethanol.

    Don’t know if there is any truth to any of that, but I have never had a single issue using Premium fuel.

  9. Bradley Says:

    A lot of Electric cars are not sold in every state, so comparing sales numbers to California isn’t entirely fair.

    Which is cheaper, lowering the price of an EV (and loose some money) or simply paying the penalties?

  10. lambo2015 Says:

    Automakers should not have to build vehicles that consumers do not want. Government is trying to put the cart before the horse. The public will not embrace EVs until the charging infrastructure in in place and until the vehicles can deliver similar range and refueling times as a ICE. Mandating ZEV’s to the manufacturer is like telling McDonalds they need to make a percentage of Tofu burgers regardless if they sell them. Hopefully as POTUS pushes for less government regulation this will be one area that gets some common sense.

  11. lambo2015 Says:

    #8 Bradley; I doubt that fuel was the cause of the converter failure. Most times its because the car is due for plugs and isn’t firing properly. Un-burned fuel gets pushed out the exhaust and will melt the ceramic brick within the converter. Running E85 in an non-E85 vehicle typically runs the risk of damaging certain plastic components, gaskets aluminum fuel rails, injector o-rings and fuel lines that cant handle the corrosive nature of Ethanol. But it would most likely take more than a tank to do any damage. IMO

  12. Kit Gerhart Says:

    #11 If you put E85 in a non-E85 vehicle, it just won’t run, or will barely run. The mixture will be too lean. Yeah, it might also damage some parts.

    #6 I did some fairly careful gas mileage checking between regular and premium in my cars, and the difference was too small to detect. Also, I can’t feel a power difference, even with the MINI which doesn’t have a lot of power, and I might be more likely to feel the difference. Still, if I were going to run either car “hard,” like playing on a race track or autocrossing, I would run the tank low and fill it with premium.

  13. Bradley Says:


    I did just have the plugs replaced at 60k. I think its the first time its needed per the maintenance plan.


  14. lambo2015 Says:

    Kit A non-E85 car will run on E85 unless your talking something carbureted. Almost all modern engines have the sensors in place to richen or lean the fuel mixture to prevent spark knock or it running lean. But it will run I guarantee it.

  15. Kit Gerhart Says:

    Will a non-E85 engine richen the 30-some per cent necessary to run on E85? I haven’t tried it, nor would I, but i’d be surprised if a regular system has that much range.

  16. Bob Wilson Says:

    #10 – yesterday there was an article about how dealers do a poor job of selling EVs. There was also a recent article about the rapid turnover of dealer staff. Small wonder EVs and plug-in hybrids sales are slow. In some areas, even hybrids have a hard time.

    The West coast has mountain ranges, sometimes on fire, that concentrates pollution. Denver has a bowl and I remember the choking smogs of DC in the 1970s. Sure today’s engines have lower emissions but they are reaching the technical limits … when not cheated.

    We own two, plug-in hybrids, and our EV miles are half the cost of gas miles. It is personal economics, not emissions that drive me.

    As for emissions, I have no problem with coal fired, electrical power generated near the coal mines and high-tension power lines export the electricity. They get both the ‘clean’ coal jobs and health benefits while I get cheap electricity. The only problem is wind and solar are cheaper than coal power.

    Bob Wilson, Huntsville AL

  17. Kit Gerhart Says:

    I believe that greenhouse gases contributes to climate change, so I would rather see less coal used for power generation, even if I had to pay a little more for electricity.

    Disregarding that, plug-in vehicles can greatly improve air quality in densely populated areas, and in specific area like SoCa and Denver. It still seems difficult to find real inforation about the end-of-life disposal/recycling of batteries.

  18. John McElroy Says:

    #14 and #15. I wouldn’t ever run E85 in a non-E85 engine. I doubt it would work because E85 vehicles have an additional sensor to measure the ethanol content, which feeds into the ECM. Also, E85 vehicles get different ECM programming. Worse, in time the ethanol will eat through all the gaskets in the fuel pump, the fuel lines and the injectors. E85 vehicles get special gaskets.

  19. Chuck Grenci Says:

    If (and when) ‘electrics’ are on par or near par with ICE then you will see the increase of sales. I don’t have too much of a problem with incentives, but when, even with incentives the ‘electrics’ come up short, well then, that’s what we are seeing now (poor sales). Forcing ‘electrics’ will meet resistance, in fact, forcing most things will see similar results. I would buy an electric (for my in and around town travels) if the price were more in line with what I can achieve with what is currently available (or at least I would more heavily consider electric) if performance were closer to what is already out there.

  20. lambo2015 Says:

    #18 Yes that is what I said in my post #11. But I know of folks that have accidentally pumped E85 into a non-E85 engine and it did run.

  21. Kit Gerhart Says:

    #20 It would depend on what percentage of E85 you have in the tank. If you run it low and fill it full with E85, I suspect most non-flex fuel cars would run very poorly, if at all. If you start pumping tbe E85, and after a gallon notice, and say oh sh!+ and fill the tank with E10, it would run fine, and there would be no damage.

    A drag racer friend uses E85 in his carbureted car, the biggest problem being that pump E85 has varying amounts of ethanol, requiring different jetting.

  22. Kit Gerhart Says:

    I read that there will be a 2 litre turbo four available in the new Wrangler. Is this a new engine, or a de-bored or de-stroked “tigershark” with a turbocharger?

  23. kurt w Says:

    Pity AAA didn’t test Subaru WRX/Forester XT turbos as those are recommended to use Premium or otherwise loose HP/MPG (roughly 15% deterioration).

  24. Kit Gerhart Says:

    #23 I guess one needs to do their own tests, and find out what difference it makes for your driving. Did you do controlled tests, and find a 15% reduction of mpg?

  25. Jonathan Says:

    I own two cars. One owners manual calls for regular gas. One calls for premium. I follow those directions as I refuel the vehicles.

    Makes the most sense.

    Those who own cars that don’t call for premium fuel and are using high test are in fact wasting their money.

    Follow the manufacturers owners manual and you are making the right choice.

  26. Kit Gerhart Says:

    25 From my experience, when the owner’s manual says “premium recomnended but not required,” you are throwing away with an extra 15% in fuel cost if you use premium, at least in normal driving.

  27. Barry Rector Says:

    Is Tesla still selling Carbon Credits to other car manufacturers? How much money has Tesla realized from the sales?
    How long will the credits last?
