CBC TV in Canada had tests done that indicate Premium is a waste of money even for some cars tuned for it. Certainly no benefit to the environment when using Premium, it actually produced MORE hydrocarbons than Regular!

Our Ottawa Subaru Club posted quantified benefits from Premium, most would only use it for their WRX & STi turbo engines. One told of a family member with a normal Lexus with Regular being recommended, yet its performance & even idling were unsatisfactory unless using Premium.

Any real experiences in favour of either Regular when Premium is in the Manual, or improved driving & consumption when using Premium?

Forresj : your the one that can't read or need your eyes checked
what have a said twice in this post so far ?

ford ranger with 4 cil 5 speed overloaded
manual says 87 will be fine , but with it in the summertime with AC on truck will not go over 50 mph and looses ground on hills(with the gas petal to the floor)

put 92 in it and will do 65 all day long even on hills (still have to hold it to the floor most of the time , but it still keeps up )

so premium provides more performance that is needed even though the manual said i should use regular

Zero benefit of using premium on an engine designed and calibrated for regular.

Folks who insist that using mid-grade or premium fixes pinging on their cars are simply masking a bigger problem in an expensive manner.

Cactusbobs... If you read my post carefully, I'm stating that premium does not provide better fuel economy or better performance, Only stupid and delusional people believe it. If you need premium because you have engine knock or require it based on the manufacturer recommendation, then I have no objections of using premium gasoline.

You should get your eyes checked.

Forresj : you should not be making blanket statements
you have no idea what we drive or where we drive it

i am not making someone rich because i want to , i use premium because i have too , both of these trucks say i should use regular in the manual , but i just can't and that's all there is to it
unless i want a top speed of 50 on the freeway in the summertime in the ranger.
in the case of the dodge , ping and knock like a engine full of marbles @ 5000 ft

so please don't attack others and call them stupid or worse "delusional" for what they use

if regular works for you , great . but there are other people in the world who are using premium to make there cars run correctly , these people are not Delusional

Toyota products seem to need a couple hundred miles to fully adjust to a change in the way the vehicle is being driven or the fuel being used. Can't immediately compare one tank of gas to the next.

Drive around like a bat out of heck for a few days. Always see how fast you can get 0-60. A Toyota will retune. The transmission will shift differently. And if you resume sane driving habits then for a few days the Toyota will continue anticipating past behavior with late higher-RPM shifts.

If you think your car doesn't idle well on regular, you need to run several tanks of regular to let it get used to it. It will smoothen out once it learns how to run on that fuel.

You will notice that this information came from an oil company that has been in business for many years and admits that premium gas is wasteful for vehicles that don't need it.

So for all those delusional people who claim premium gasoline provides better fuel economy or better performance, you better think again. You're just filling the wallets of hedge fund managers, terrorists and oil fatcats executives. They are all laughing at you. You'll find me laughing too if I should find you standing on line at the pump begging for a couple of gallons of gas. Just keep walking because you won't get help from me. I have no tolerance for stupidity.

----------------------------------------

Why should I use your premium gasoline (91-93 octane) instead of regular (87) or midgrade (89)?
To find out what octane your engine needs, first check your owner's manual. The recommended level is often 87 octane. Some models have high compression engines which are designed to utilize the octane levels of 89, 91 or higher.

Ordinarily, your vehicle will not benefit from using a higher octane than is recommended in the owner's manual. But if your engine knocks or pings at the recommended octane level, you may need a higher octane gasoline to prevent the knock. Knocking may occur under certain conditions. A small percentage of vehicles may knock because of variations in engines of the same model due to manufacturing tolerances, or because of an unusual build-up of engine deposits. Other factors such as extremely hot weather, changes in altitude or hard driving conditions (like towing a heavy load) may also cause knocking. Many modern vehicles are equipped with an electronic device that detects and eliminates light knocking before you hear it.

Not only is there no mileage advantage, but some older cars (older than 15 yrs) when tuned for 87 octane and you use 89 or 91 octane, can have the water pump fail earlier than expected.

I would have to say that if your car is rated at running off 87, it's best to put that in. If rated at 93 and you put in the 87, you're not going to run as well as you could.

summertime with AC on , truck will not keep up with traffic , foot to the floor will loose ground on hills with regular gas . with Premium much better
in winter with no AC regular will work fine

1993 Dodge Dakota : V6: in the mountains of Arizona , truck will PING really bad on regular but not on Premium

In most cases, using premium will not improve mileage unless the car's ECM can advance the spark sufficiently to burn premium effectively. Most cars are designed to use 87 octane only and can't do this.

Some of the engines produced in the last 3-5 years can give somewhat better mileage with premium because they are designed to use a greater range of octane fuels but the improvement in mileage isn't usually enough to warrant the increased cost of premium.

There are manufacturers who tell their customers that their engines are so good that they have to buy the most expensive gasoline, Z rated tires, etc, not because the car needs it but because the customer needs to be told his car is so good it has to have "only the best".

For an example find an owner's manual for 2000 Toyota Avalon. Carefully work the grammar mathematics on the wording used to specify what fuel to purchase. It weaselly says there might be unspecified benefits from using premium. But 87 is the "minimum". 9 out of 10 Avalon buyers read the paragraph as saying 93 octane is absolutely required else doom and gloom will result. But diagram the paragraph and sentences for them they see it says 87 is required and totally noncommittal as to what might happen with anything else.

The main thing I can't rely on for driver fuel tests, comparisons, ETC is; Open road tests with any vehicle is then subject to head, tail, side wind forces somewhere during the test travel route.

The very same travel route at different times for example, calm of the day changes with Nature Forces, then there is the fuel filler neck size V/S the pump nozzle, fuel expansion temps to deal with.

Saying consistency isn't always present when one figures that natural test coarse, along with daily temperature changes, engine fuel evaporation purging of collected fuel vapors(EPA thing) incorporated into your vehicle, sloshed gasoline > by your driving habits are subject to more evap.fumes, ETC. Then there is the changing humidity factor (even morning dew) to take into consideration, remember your engine breaths in natures air into is combustion chambers.

Still speculation is good for better driving habits where fuel savings is the main efforts but at the same time too many variances gives even top engineers headaches, my take........

In old cars putting a higher octane level may help. it doesn't hurt to try. if you don't feel any change just go back to 87

I did test this on a 2007 Mazda 6 4 cyl.
I tried this while on my last vacation...I started off by running several weeks prior to vac. by running 93 octane...then for half of my trip...then on the way home I switched to 87...I tried to be consistent and use the same brand of fuel through the whole test (BP in this case).
I found that the MPG did increase slightly, but only enough to just pay for the increased price of premium - And that is driving VERY carefully...not worth it!

If you continual use premium you might see a difference but I don't know if it pencils our. If you constantly switch or just compare one tank full you won't see a difference newer vehicles have an adaptive fuel injection and don't change over night it takes a while for them to relearn how much fuel to inject.
