Question re: GASOLINE

  1. For those who know, is it really better to use high octane gas? Some say you only need to use the octane level recommended in your owners manual (mine says 87 or higher for my Honda). I've heard 2 views:

    Higher octane burns cleaner and improves the function of your engine.

    Higher octane is just a farce to make you pay more $$.

    I admit I have tried higher octane and I did notice a difference in the way my car responded, especially when accelerating. Or, that all could have been in my head. :chuckle

    What say you, petro experts?

    In some vehicles it does matter.. Some high performance engines/cars/trucks require a higher octane... I would use what the manual says.. Mine says the lower ones is sufficient for my SUV...

    I doubt this answered your question..

    My mechanic said that if I could afford it I should move up in octane. I have an older car and it was acting funny when driving around 35-40. I went up one notch and after a week or two the weird thingie stopped.

    My husband is a mechanic. He says to stay with the manufacturer's recommendation. Your engine only burns cleaner on higher octane if it is set up to do so. Otherwise, you are just spending your money. He says that your engine life will be greatly increased if you are religious about changing your oil every 2000 miles. He has done this on my van and we are up to 100,000 miles. I think the next 100,000 miles are actually the ones that will tell the tale.

    Thanks, all! I'm pretty good about having the oil changed every 3,000 miles and doing the recommended maintenance schedule.

    I'll be sticking with the recommended 87 octane for now.

    I have to use a minimum of 91 in my Jetta, which means I'm usually buying the 93 octane. It's a new car, so I'll let you know in 10 years if it was worth it!

    That's what they recommended for an octane level in the Jetta manual?? Sheesh!!

    Yeah, but my dad insisted I get the V6, so that's probably why. BTW--It's soo much fun to drive!

    Hi octane fuels will often give better mileage and let your engine develop more power as the fuels are denser
    This will only help cars with electronic fuel injection as a rule.
    Carburettor cars will need to be tuned for this fuel .
    To best decide what fuel is going to be better for you keep a log book And compare costs over several tanks of fuel., or if you are just wanting the extra power and or less emissions.
    no damage will be done to a modern engine by useing these
    improved fuels

    I dunno, LV..
    what I do know is..
    Chevorlet recommends 89 octane in my Silverado, but if I don't run 91 or higher, it "misses". As long as I run 91 or higher, it purrs like a kitty.
