Premium Fuel?

[stb616]

Gota love it! Premium gas here in Michigan is back up to $2.95/gal

I thought maybe you folks would have some insight on why it is and if a Disco really needs Premium Fuel. So????

I Usually use Premium and sometimes midgrade, but have always wondered why I do this and if its really needed.


Thanks

Our Rovers have a very old, poorily designed engine that is very prone to carboning up and the problems that causes. You can get away with running a lesser grade once in awhile but if you do it all the time, your MPG and torque will take a dive.
Carbon is the biggest problem and even with a high octane gas it is still recommended to use a good gas additive a couple times a year to prevent many of our common problems.
You won't save any money in the long run.

With $339.9 billion in revenue and profits of $36.1 billion, Exxon (Research) earned more than any U.S. company in history last year -- more than the profits of the next four companies on the FORTUNE 500 combined.

It must be nice to own a commodity that everyone needs... glad I only drive a mile to work.

It is a neccessity to run premium? I am but a poor college kid that can't afford the premium. Is running regular 87 octane gonna cause problems later down the road?

You guys would be suprised how much running premium actually cost....probably not as much as you think. I have calculated it out and its something like $300 extra a year. With premium I get more miles per gallon first off.....second of all, its not worth the risk of damage to your vehicle by running less pure fuels. Lifters, etc. will take wear.....when it comes down to it....its not worth saving that little bit of money.

Running low octane long term will cost you- the carbon buildup, the loss of performance resulting in lower fuel economy etc. If you want to save money at the pump, drive gently so you use less fuel. Using low octane won't cause a problem you can HEAR because the knock sensor in the engine is retarding the timing to compensate for the low octane fuel. Retarding the timing causes power loss...

In this case, I can't wait to start working, so I can start runnin' Premium again............well sh$t wait, I dunno if my RRC has ever taken a sip of premium. LOL

Well, might as well start running ASAP.

right away you should notice a tad more power and better gas mileage.....so its not like its not worth it.

Premium is all that I run in my D1 and sometimes with lucas fuel injector cleaner. once I ran regular for a test and my D1 mileage suffer bad and was very sluggish. So for "MAJESTIC" it's 91 all the time. If gas really creeps up then my 99 dodge neon will set things off real nicely.

Just one of those rover things that you have to get used to. To me spending the extra 20 cents a gallon is well worth it I stay out of the shop more often. I have never put 87 in mine and don't plan on it. If worse comes down to worse I'll just start taking the greyhound to work and drive my disco for fun. The gas prices will go back down hopefully, well I sure hope so!!!! I'm not selling my disco no matter how bad my wife wants me too lol..

Well, hopefully I will notice something else. Would regular grade being run all these years since 1994 make the motor idle a little rough, nothing extreme, but like a once in awhile miss in the motor?

Man, and I thought running Premium was a way of saying, I got an expnsive car, if you can afford the car, you better damn well afford the gas. Well sh$t, I got this RRC thorugh my mother (the spoiled SOB I am LOL), who bought it off people that are doctors, so they didn't know too well to put premium in. Plus we only got her for like 2500 bucks, it was a steal, well almost. Despite the hood being bad, a minor sagging in the rear head liner, and some bald ass tires, I dunno, wasn't too bad.

Not sure if it would cause the rougher idle, but I would be willing to bet there is some major carbon build up. In addition to switching to Prem. grade (only cost a few more bucks total per fill up) I would think about running something like seafoam through it to help clean things up.

I did the Sea Foam thorugh the fuel pressure reg. vacuum hose, using about half the bottle, I think what it told me to do. But I cleaned some nasty crap from the inside out, stunk like sh$t too! But this was ahwile ago, when I posted about it in like General Discussion or something. LOL

Might have to do again since I filled up several times using regular 87 octane since I did the clean out. Not sure, would hurt I would think.

But yeah, after this weekend, after burining off the rest of the 87 in the tank I got right now, I will have a full tank-o-premium in there. Was is premium octane rating anyways? Like 93 or 97 or something? Last time I used premium was when I drove my Probe back in High School (still have the car), it got a decent 30 mpg's on the freeway, according to the electronic computer display that told me everything from, outside temp. to instant fuel economy. Sometimes I miss the great gas mileage. LOL But the hell with it, I got a truck now, I can go anywhere.

DONT USE preminum in the Probe if you still drive it. It is a waste to use the higher stuff in that car. I had a 95 Probe GT and used 93 in it all the time until I had a problem with it. The tech said that it was becuase of the preminum gas. I forgot the exact problem as I am getting old and it was 10 years ago.

You should always use what is recommended for the car. Certain engines are designed to run high grade and others are designed for the lower grade. In cars like the probe you get no advantage to using the higher grade gas.
