[net.misc] Who Uses Regular Gas?

gnu (01/28/83)

My 1980 Honda motorcycle runs fine on cheap old regular gas, and gets about
50 miles/gallon.  I'm sure that many newer cycles also still use regular.
(PS: Lowest price I've seen in SiliVali/SF is about $1.01 in Mt. View).

The ARCO station in King City, Oregon just hit 88.9 cents per
gallon for regular gas.  I can no longer get ten dollars worth
of gas into my car!

My car is something of an oddity this way.
I have a Datsun B-210 wagon.  (only *slightly* odd in itself...)
Apparently, in '77 or so, they went to unleaded gas.
Then, in '79, they went back to regular.
Finally, in 1980, they returned to unleaded,
and have continued to used it ever since.
I gather that all their other models used unleaded regularly (:->)
since about the same time as the 210.
I have the 1979.

	Try finding leaded premium gas (92+ octane) for a 1965 Oldsmobile
98 convertible...

I do not think that **any** motorcycle uses unleaded gas.

The years for Datsun's regular gas use are not correct.  I have a 1978
B-210 and a 1978 280Z.  Both use regular gas.  California cars at that
time used unleaded and my Z has a place for a temperature indicator light
for a catalytic convertor.  Incidently, at the time GM had a big ad
campaign to the effect that Datsun was trading fuel economy for regular.
Considering the 5 years I have had with 40+ mpg on the B-210 and 30- mpg
on the 280Z along with the price differential I think the Datsun approach
was a good deal at the time.  It is my impression that Datsun went to
unleaded for some models in 1979 and others in 1980, but I am not sure.

Because of less-strict emissions standards in Canada, many cars here still
run on leaded gasoline - my 1981 Rabbit for example.  Prices for fuel seem
to be about 50% higher than those mentioned for the U.S.

Yes, but almost any motorcycle CAN use unleaded gas, if the rider chooses to
pollute a little bit less.        -- Larry West, UCSD

Larry West, UCSD, said, in reference to this topic:

	"Yes, but almost any motorcycle CAN use unleaded gas,
	if the rider chooses to pollute a little bit less."

True, BUT --

	1.  The contribution to atmospheric pollution, by all
	    motorcycles, is less than 1%.  Polluting a little
	    less will be an improvement of far less than 1%.

	2.  Regular is less expensive than no-lead; using
	    unleaded gas, at a higher cost, will increase your
	    engine's tendency to detonate (pre-ignition, or knock).
	    This is particularly noticeable on warmer days (when
	    most motorcycles are used) with air-cooled engines
	    (most motorcycles are NOT liquid cooled).  Typical
	    octane (anti-knock rating) for regular is 89, for
	    unleaded, 87.  Of course, if you don't like the
	    engine knocking due to your use of the more expensive
	    nolead, you can always pay even more for premium
	    unleaded!

	3.  Unleaded gas causes MUCH faster wear on valves,
	    valve guides, and valve seats than regular, both in
	    cars and motorcycles.  The combustion after-products
	    of tetraethyl lead act as lubricants under the extreme
	    high pressure and high temperature conditions that are
	    encountered by valves (particularly exhaust valves).
	    The use of regular gas will extend valve life by
	    several hundred percent.

Regular does have one minor drawback -- spark plugs last longer when
unleaded is used, but I can change spark plugs in 10 minutes, at the
cost of a few dollars; the cost of replacing valve components is in
the hundreds of dollars!

If your engine (car or motorcycle) runs properly on regular,
you are wasting money and accomplishing very little by using nolead.
