Is it worth spending the additional $ .20/gallon for my 2000 sedan?
I've heard mixed reviews on this topic.

You will only get better economy if your car requires it.
The manual, gas door, or gauge cluster will say premium if it is needed.
If your car is modified you may find some benefit as well. I am talking about a retuned ecu, different ignition timing, addition of a turbo / supercharger, performance rebuilt engine, etc.
Even if you have intake, header, exhaust, you won't need premium unless it is required by the factory.

No, it doesn't. The higher octane only helps if your running a very high compression engine and your car would be marked next to the gas cap if it needed high octane gas. Otherwise it is simply a waste of money. Using high octane gas in a regular car is like using tires for a sports car on a go cart - it will work.

intense-octane gas is not any stronger that nicely-known gas. that is considerable benefit over nicely-known gas is that that is form of greater good to ignite (that is what the octane score measures). that is often required in automobiles whose engines use intense compression (those are generally contemporary in intense overall performance automobiles). utilising nicely-known gas in those automobiles can bring about predetonation (called 'ping' or 'knock'), that may bring about engine harm. this suggests that utilising intense-try won't help your mileage any, inspite of the certainty that some automobiles, like the Chrysler 300M, can funds in on the better octane to alter the engine's ECM to make somewhat greater capacity, yet this usually decreases mileage as adversarial to helping it. whether there have been a mileage benefit to utilising top classification gas, it would be particularly reasonable and the earnings may well be offset via the better purchase cost. in the journey that your automobile can use nicely-known, achieve this.

High-octane fuels may improve your car's performance and fuel efficiency, but are also more expensive, so the increased fuel efficiency isn't likely to save you money.
Take note that if the recommended gasoline for your car is 91octane, then using a higher gasoline offers absolutely no benefit. It won’t make your car perform better, go faster, get better mileage or run cleaner. Your best bet: Listen to your owner’s manual.
As a rule, high octane gasoline does not outperform 91 octane in preventing engine deposits from forming, in removing them, or in cleaning your car's engine

i have noticed a difference based on octane rating. the manufacturer of my car specifies 90+ octane.
91 octane gas is the norm around here, but while touring the United States, i was able to fill up with higher octane gas (95 the highest). i usualy get 260 miles to the tank, but with the higher octane, i was getting near 400 miles to the tank.
when i was in New Mexico (highest octane was 89), i got 250 miles to that tank.
i was able to compare while driving freeway miles around 60-80 mph over a distance of about 8,000 miles for five weeks.

Only in vehicles with high compression engines. Follow the manufacturers recommendations. Most older cars will run fine on 87. Some require 89, but only higher compression engines require 93.

newer cars cars use charge air temperature senser to calculate spark timing. so in colder months you can use a fue points less - the rest of the year just use the recommended octane.

follow your car manual. only put high octane gas if it requires it. the reason for high octane is to make the engine not knock. it does not give extra "power" to the engine whats so ever.

it doesn't always help even the cars that was designed to run on it,they did a study on this a while back,and the majority of the cars now run as good on regular unleaded as they do on the premium,so its really not worth the extra money you spend on it,some people just feel better if they buy the better gas and think it helps,,but in most cases it doesn't,good luck,i hope this help,s.

If you have aluminum heads you'll warp the engine big time, just change your spark plugs from whatever they are to E3 spark plugs and your distributor cap and spark plug wires big difference and that increases fuel efficiancy
