  • Talking Cars: If you’re gonna pay, you gotta play

  • My car along with my wife’s car state in the owner’s manual to use 93 octane gasoline. As you know, the price of gas is out of sight, and premium gas is 20 to 40 cents higher than regular. My question is, is there any long term damaging effect using the 87 octane gasoline in either the BMW or Lexus?

  • QUESTION: My car along with my wife’s car state in the owner’s manual to use 93 octane gasoline. As you know, the price of gas is out of sight, and premium gas is 20 to 40 cents higher than regular. My question is, is there any long term damaging effect using the 87 octane gasoline in either the BMW or Lexus?
    ANSWER: If it is any consequence, all my personal vehicles also require 93 octane. The premium is at an extra cost just as the cars that require its use. My wife also wanted to start using the 87 octane. I will tell you the same thing I told her. The higher octane gasoline burns hotter, slower and cleaner than the lower octane gas. The higher octane will leave less carbon and deposits on the internal combustion area. In my opinion you should only use the lower octane when the premium is not available.
     
    QUESTION: I own a 2010 Hyundai Elantra Touring car with 24,000 miles. The transmission has been straining for some time. The Hyundai mechanic told me the transmission fluid is burned, they don’t know why, and for me to wait for 30,000 miles to change it. What could cause a vehicle with 20,000 miles to have burnt transmission fluid?
    ANSWER: I service a lot of vehicles at both locations and see a lot of burnt automatic transmission fluid on some vehicles with low mileage such as yours. Even though your car has a long warranty, I would still suggest changing the fluid. Most transmission pans have a drain plug to drain out the transmission fluid. When using the drain plug and not a transmission flush machine, I suggest to drain the fluid, refill it and let the engine idle for 10 minuets, then drain the fluid again. When you drain the transmission fluid from the drain plug , only 3-4 quarts are drained. We did have a similar problem on a 2010 Elantra daily rental, and the transmission did have to be replaced under warranty.
     
    QUESTION: What can you tell me about the new Jeep Compass 4x4 with the 4 cylinder engine?
    ANSWER: There is no question that with the price of gas rising almost daily, people like you that want a 4x4 are interested in four-cylinder power. In years past the four-cylinder engines had trouble moving front drive vehicles, not to mention 4x4 vehicles. I had the Jeep Compass Latitude 2.4 liter four-cylinder CVT automatic and 4x4 option for a week and was surprised in all areas. Let’s start with the power and performance: nest firm heated front seats and steering hub controls. Low entry into the seating and rear tailgate area make it easy to enter and exit. The suspension is unlike the hard bouncy Jeeps of yesteryear. Pricing on our test Jeep was $23,445 plus $780 destination city mileage 23 highway 27. Our average combined driving was 25.
