That information is in your owner's manual under "fuel".

Excuse me sir,
I don't have an owners manually.
But thank you anyway.
If I get one I will know where to look.

your owners manual will say that you should buy regular.but my car runs best on midgrade .try the regular if you get no pinging and it runs good well then buy regular.i have a little bit of a cam and the intake has been ported and the distributer is advanced a little over stock.

 

[PghMike]

Run 93. Better safe than pinging.

Order an owner's manual.

Your 82 will run on cheapo no lead.
It will love you a little more if you use premium.

 

[Hib Halverson]

Minimum octane for MY82 is 87.

On hot days, if you run the engine at high load, and you don't like getting knock retard, run it on 89.

Minimum octane for MY82 is 87.

I don't think premium unleaded even existed in 1982. Anybody know for sure when it first appeared on the market?

Thanks again guys.

What if I split it and take the one in the middle?

Mike,
AMOCO ( AMERICAN) was unleaded premium back in the 60's and up. When I was a kid working at an AMOCO station it was 95 octane, regular was leaded & 90 octane. By 1977-78 or so the leaded regular was phased out. The premium was called "white gas" and we got a fair share of vettes using it. It jumped up to .50 a gallon in '78, then $1.10 or so in the early 80's and stabilized. The economy adjusted and oil companies continued to make huge profits, now forget it. Prices are out of control and it will take affect on everything again.

JIm

yes if you want to take one up the middle for the team well then have at.

I knew when I entered it that I didn't say it quite the way I wanted to.

So,I guess I'll have to take one for the team.
(I hope it's the one I was looking at)

95 octane rating back in the 60s is equal to about 89 octane today given the change in rating system which occurred in the mid-late 70s.

I think it was the mid 80s when we first saw 91-93 octane ( new rating system) unleaded here.

I think it was the mid 80s when we first saw 91-93 octane ( new rating system) unleaded here.

Catalytic converters were introduced in 1975, so that's when unleaded fuel was mandated in the U.S., in both regular and premium grades.

The system(s) by which gasolines are rated for antiknock quality has never changed.

There are two rating systems: Research Octane and Motor Octane. The test for the latter is more severe and tends to make the test engine more prone to detonation, so for a given fuel sample, the Motor Octane Method (MOM) will result in a lower octane rating.

Back in the old days, there was no "standard," but most refiners rated their gasolines using the Research Octane Method (ROM) because it resulted in a higher number and its obvious marketing advantages.

In the mid-70s the government decided to regulate octane ratings and the resulting system became an average of the Research and Motor Octane numbers or...R+M/2. This is the way gasolines are rated at the consumer level today.

A gas that's rated 91 on the pump might be 93 ROM and 89 MOM.

That is also why here in Europe the fuel "looks" like its has a better quality. Here everything is in ROM (RON).

And that was my point above- up to the mid-70s, the North American market was accustomed to seeing the RON number advertised on the pumps and mentioned in the owners manual with respect to octane requirements.

People here that are not aware of how gas was sold in the 'good old days' might look in the documents for their newly acquired '69 big block wondering where and how to get 98 octane.

Yes, we had regular unleaded here also in '75 but definitely no premium unleaded. Do you know of any cars built in that era that required premium unleaded? I was under the impression that anything and everything would run on regular.
