78 Suzuki gs 1000 gas octane

[Bjones89]

I know yall... stupid question but do y'all know what grade of octane gas do I use in my 78 grand? I know most bikes take 91 but that's wat I seen on most newer bikes and I don't own a owners manual...I would love to tho but I know that'll never happen!

This owner's manual from Cliff's site says 85-95 octane.

If it is pretty much stock (compression, displacement, etc.), all you need is "Regular", which is probably 87 octane in your area.

In the summer heat, if you hear it pinging a bit, use some 89 until it cools off a bit.

Ethanol free if possible.

If you have WAWA convenient stores up there, they sell nonethanol with 89 octane. It's gotten up to $2.99 a gallon down here, but when your only getting around 4 gallons at a time, it's affordable.

Gas loses Octane numbers over time. If you don't go through gas regularly it could be of benefit to pick a higher number...

I haven't generally had an issue with 87 with a bit of stabil in it personally....

How much for petrol/gas do you pay in USA, Here in UK we pay around ?1.25 per litre, there is around 3.8 litres in 1 US gallon.

[Steve]

Just doing some conversions:
1 Pound is $1.39 (today).
1.25 Pounds per litre would be $1.74 per litre.
$1.74 per litre for 3.8 litres would be $6.60 per gallon.

The station where I usually fill up is at $2.25.

In your currency, that would be about 0.43 per litre.

It appears that you are paying about three times as much for fuel, but let's look at the BIG picture for a moment.

Let's say that you put 15 litres of fuel in your tank. At 1.25 per litre, that would be about 18.75. How long did you have to work at your job to earn that much? (Generalizations, only, please.)

That same 15 litres would be 3.95 gallons, and at Steve's rate of 2.25, would cost about $8.90. The Federal minimum wage law here is $8.00, I think, so the guy flipping burgers at McDonalds would have to work just over an hour to earn enough to fill the tank. Some who are in better-paying, professional jobs, will earn $25-30 or more, so they would have to work for 15-20 minutes to earn enough to fill the tank.

If your rate of pay is somewhat comparable, the cost of fuel is really no more or a burden.

Pretty much without fail the UK is 2 times the California (Los Angeles) price. It's been approx that way despite multiple currency changes ever since I've been paying attention... (2005).

And California fuel prices are at least $1/gallon more than the USA national average.
