  2. Yes. Techron is a popular brand, but I've used inexpensive brands
    successfuly in my '85 765T and other cars.

    If you habitually use "top tier" gasoline brands (see injector cleaner
    isn't useful. Otherwise I recommend about as often as the oil is changed.

  4. I'm looking more into this recently and I'm really tipping toward using "top
    tier" gasoline regularly. It was sparked by a couple of people who had
    trouble with 'pinging' in their 2001 Toyota Prius cars. In each case the
    mileage was over 100K miles. The prime suspect is carbon deposits, one of
    the bad things top tier fuel is designed to prevent. A couple of links I
    found interesting:
    Although the second link does have something to sell, the background sounds
    right and the claims make sense in terms of my experience as a DIYer. Every
    cylinder head I've ever had off had carbon deposits and every piston head
    has also had deposits. In another forum another regular echoed that, except
    that the few that had used top tier gasoline exclusively did not have carbon
    deposits. Hmm.

    The same contributor mentioned he has a Shell credit card that gives him a
    5% discount on gasoline, which would put it on a par with the very cheapest
    gasolines. I have to look into that. Carbon deposits can be bad news,
    especially in a turbocharged engine.

    I might be cheaper to buy the cheapest fuel and use a liquid to clean
    valves, injectors, etc. .

    Before using the "ultra fuel treatment", I used a cleaner only for the
    injectors and the result was marginal improvement.

    Using a bottle of cleaner every 2-4 years shouldn't do too much harm?

    Here in Canada, a litre of premium is about 10 cents more than the
    cheapest fuel. Since there are 4.5 litres in a (Canadian) gallon,
    that's 45 cents more per gallon. 45 cents out of $4.50 means about
    10% more for premium fuel. If you spend $3,000/year on gas, you pay
    $300 more. It might be better to simply pay someone to open the
    engine and have him properly cleans the valves, injectors, etc. .

    My $0.02.

  6. Or not - here in Flagstaff the price difference between Chevron or Shell and
    the very cheapest gas is less than 15 cents per gallon, amounting to only a
    three dollar difference on a twenty gallon tank. More often the margin is
    closer to 7 or 8 cents (sometimes they are the same), which would cut the
    difference to about a dollar and a half, about the price of the cheapest
    additive. In it says,
    "Deposit control additives such as polybutene amine (PBA) were introduced in
    1970 to help keep injectors and intake valves clean. The only drawback with
    PBA is that too much of it can increase combustion chamber deposits.
    Polyether amine (PEA), by comparison, cleans fuel injectors and valves, and
    does not increase combustion chamber deposits. In fact, it helps remove
    accumulated deposits inside the combustion chamber..." It is crucial to know
    just what is in the additive, and the cheap ones are typically just
    petroleum distillates.

  7. In the old days higher detergency was related to fuel grade, but the Top
    Tier designation does not allow for that. The Top Tier designation is not
    related to fuel grade; all grades at all outlets of a top tier brand must
    meet the standards for detergency for the brand to be certified "top tier."
    If the car is spec'd to use regular, use regular at a top tier station.

    It really isn't an option to plan to have the deposits removed by a
    mechanic; the procedure is essentially the same as replacement of the head
    gasket(s). Removing the deposits manually is the expensive emergency surgery
    the improved gasoline is supposed to avoid.
