I started with 87 regular and now use 91.

We use regular, but stick with Chevron, Shell, or Exxon. Unless you're having detonation, then there's no need to run anything more than regular, or whatever the manufacturer recommends. There's no advantage to increasing octane rating when it's not necessary, it improves nothing.

Now my mustang used to be able to run regular, but now I have to run premium with water/methanol to make power with the modifications that have been done! lol it's fun lol

Why would you use 91 octane? As RyansQuick6 mentioned, nothing is gained by using 91 octane fuel when your vehicle runs on 87. It does, however, cost more... that's not a benefit.

Don't waste you money and stay with regular fuel. I did lots of comparisons with my Toyota on fuel grades and found no difference except cost. Honda recommends regular and believe me; if it needed other they would say so in manual.
Happy driving

One of the MANY reasons I chose the CT was because it runs on "Regular" gas. Even the Ford Taurus we also looked at requires/suggests/recommends Premium fuel. Of course, here at 5K feet in altitude, the effective CR is a little lower than sea level so the CT should run absolutely fine on our 86 octane regular!

Regular or Premium Gas

I've tried the odd fill up of premium gas if there is a difference it's so small not worth the extra $$$.

I now agree with everyone. After testing different grade of gas, regular 87 unleaded is good and cheap. And one funny thing you all may want to know, while I was using premium 91 unleaded, the dual exhaust pipes made "white smoke" in idle. It's like running in cold weather, don't matter whether engine is hot or cold.
Once I switch to 87 unleaded, white smoke is gone.

Now I am happy with regular gas. cheap, no MPG difference with premium.

Hmmm, my Honda dealer actually told me to use the premium 93 octane gas.

I know that is wrong...

With 87, I get just a little valve clatter after it shifts into top gear. After I filled up with 91, the clatter went away. Just my experience. The same is true with our 2004 V6 Accord.

Regular, because that's what the engine is designed for, from a few nondescript (aka cheap!) places. From what I've read, getting gas consistently from the same place (brand name or not) is better than fueling up at many different stations.

My '65 Corvair requires HIGH octane. Amoco used to be the best, but they are now owned by BP). I get my high test for the Vair from the same nondescript places and neither engine pings.

Food for thought: A modern day race aficionado that I know (very NICE Mopar and Ford vehicles) swears by Shell and never runs his tank below 1/4 remaining, an old school racer I've known for > 30 years says Shell gas is the absolute worst and always ran his tank down before filling up. I always run my tanks down low before refueling. Your mileage may vary

Run 87, no problems

I run PetroCan 87 octane with no issues. I was considering Shell since it didn't have any ethanol added but now I'm told that it does, so I'll continue with PetroCan and collect the points.

Melchor, I wonder if that clatter was due to a bad batch of gas?

Like the 'masked man' I wanted a car that runs on Regular gas.

I don't think it was a particularly bad batch of gas, because it does it in the 2004 accord everytime I run 89. However, it could be the BP gas I buy. I always buy gas at the same BP station on my way to work. Next time, I'll try 89 from the Exxon accross the street.

I always bought my gas at the cheapest places- grocery stores or Sams and Costco when I had a Lexus ES. Never went with a brand name gas. Of course, I had to put premium in but it was still running well at 105k before I traded it in for my Crosstour.

Point is, I think gas is gas, And as long as you follow the manufacture's recommended octane you will be fine.

As someone who worked in the oil field, I can tell you that for the most part, all fuels are the same. The difference with "bargain brands" is that they have more additives and stabilizers since, in many cases, they are purchased as surplus.

It's a little harder for the average joe to see the difference in a regular car, but when you're driving something that is very finely tuned, you definately start to notice the difference between brands.
