well ours are not marine equipment ,but i thot it was a pretty good explanation of
problems an what to look for. unless hes just wrong on his basics.afraid i wouldnt know enough to know for sure.
 
I run premium in my saws. Echo recommends 89 octane or better, and my blower and climbing saws are Echo so regular is out of the question for me, and this article gives another reason for me to spend the extra 10¢ per gallon for premium.
I have never heard a good reason NOT to use premium in my 2-cycle stuff, other than the extra octane is 'wasted'. For 10¢ per gallon, I will 'waste'.
 
The problem is that ther are only two grades of gasoline produced. 87 and premium. 89 is just 87 with a small amount of premium blended in. Therefor the author's statement about 89 being superior to 87 is quit comical. Goes to prove you cant believe everything you read on the internet. BTW I run premium in all my two strokes and 87 in all the engines with two extra(uneeded) strokes.:D
 
I can think of a number of problems with the article, but the most egregious is that the writer doesn't really know what in the heck he's talking about, merely repeating (poorly) some of the stuff he's heard.

It starts off with a poor understanding about how carbon accumulation affects an outboard motor and what causes it. It goes on as he tries to convince us that 89 octane gas, pumped through the same pipelines as the other stuff, somehow doesn't pick up the contaminants the same way that 87 does and probably won't cause carbon build-up.

He is right about quality control with the gas product, but we all know about that, right?
 
egregious?
Now that is a word that is not used too often.

I am no tightwad, but I have yet to see any problem or failure
using regular fuel around here. However, I do not work on
modified saws, so higher octane may be needed there.
Not trying to be "recalcitrant" and "disputatious", but
octane is not much of an issue around here. If one feels
his saw runs better on premium, then he should buy premium.
No one uses enough fuel in their saws to make a big deal
about the cost difference. I run regular in my vehicles, and fill
my shop gas at the same time, no big worry about it. If I had
ever seen a failure attributed to using regular, I would preach
using premium. But since I have not, I won't. No tightwad about
it. Just realistic.
Higher compression ratios and fuel quality in other regions
are tangents to this discussion.
 
dang i forgot to read the main article.
id went to engine exam which talked vacuum an compression . guess ive heard so much about the octane issue ,that i automatically look for something else ,when its mentioned.my opinion ,if u 2 cycle are running good then stay with what u doing. if not ,then is the time to try some different things. thats what put me,where im at now, on the issue.
somebody got to tell me what egregorious,or what ever it is ,means.
i want to use it next time i catch a few fellas shootin the ----. just want see the look in their faces.:D so before i use it
and somebody think im cussinum.
what do it mean.:)
 
I think the Latin root has something to do with herds{Llamas
maybe}, but it is one fine looking word anyway.

But as far as 87 octane goes, any failures or problems that
can be blamed on it? I haven't noticed any around here.
 
When I was visiting Brett (treeman14) in Tampa for a week back in July/Aug, I had a little trouble. My saws always start on 1-2 pulls. When working there, I had to use their mix gas which was regular with Stihl mix. By the end of the week, I was having fits with my climbing saw, sometimes taking 5-6 pulls in the tree. As soon as I got back home and ran a tank of my mix (premium with Stihl mix) through my saw, it was back to 1-pull starting.
 
I get the highest octane that I can buy when I get gas deliverd .I had a problem about 4 yrs ago when they started selling oxygenated gas in the winter months. My old front end loader with a International gas engine would freeze up. I mean the carb would turn to a solid block of ice after only a short time. The company I buy the fuel from told me the only way to stop this was to buy the higest grade I could buy I did and never had a problem since. I dont know what is in the better grade gas but it works for me! and the cheap stuff won't
 
I don't want to recountant or disputate Fish's Llamalove but I've always used regular in all my equipment, no problems I seen yet from using it. My old 76 D100 wouldn't climb a hill without high test though?
 
two words

Fish you used the same two words twice that make a big difference, "around here" . I am in MI, and we have some terrible gas compared with other places I have lived and visited. No I dont break out the chemistry kit and check. I lived in CA and ran different toys and cars and broke down a few and they were usually pretty clean. In SD the gas was even better, coming from the refinery right in Wyoming and montana. Every two cycle or 4 cysle I have worked on here in MI has had deposits built up so bad, causing all kinds of problems including spark knock and fouled plugs. I think the further they haul it the more funk gets mixed in. I have a coulpe engines from AZ, again pretty clean, the ones from FL look like the tried to burn fuel oil in them. I run the best grade they have in all the toys.
 
That is why I used the words "around here" and also included
the disclaimer about "other regions". I would have assumed
you would get your fuel from the refineries around lake Erie.
I am not trying to convince anyone to not use premium. But
as far as octane level, I see no difference either way.
Carbon buildup and fouling plugs are usually due to a rich
fuel /air mix "around here".
But use whatever you deem best. MI is a beautiful state,
a tad chilly in the winter.

whats the difference between octane level and regular/premium gas?:rolleyes: are you pumping straight from the pump - because if you are the first couple of gallons are not very likely to be premium:D
 
No , I am worried about the issue a whole bunch. I click regular
on the pump, squirt an ounce or two into a flask, have someone rush it to a lab for testing, before I fill my fuel jug and my van.

If he comes back with the results of 87/89 octane, I continue
filling my jug and vehicle. I used to just fill my jug first, but when
my saws ran great and did not explode from using 87 octane,
I would go back and complain that the premium had corrupted
the quality of my regular, and demand my money back.
The issue between regular/premium has sunk to one of
fuel quality and not octane level, which is another tangent.
The main contention I originally had about using premium fuels
was that all of the extra additives in premium can attack fuel
system components, but since fuel chemistry varies widely from
company/region[maybe], the fight is a little silly. The blanket
assumption that premium is always better, may or may not
be a valid assumption. But since the original discussion was
about octane, not fuel quality, I will stick to my original stance.
Either way, we are having fun!
 
I am only here to start trouble. I just pick on the ones that take this a little too seriously, cause they need it.
But I will stick to my guns, against all odds. I have been a member here a lot longer than most of you, I was just poking fun
at those that made mvp in 2 weeks, and the incessant silly posts
they made. I am all for intelligent discussion, but when folks
take the high road, and use terminology aimed over the heads
of all the other posters here, whether they truly comprehend it
or not, I feel compelled to step in. I believe Dagger knows his
s#@%, as well as the hotsaw modifiers here. Walt was close,
but he heaped too much stuffing on the plate, and it bit him
in the end. Lambert is just Lambert, he is realistic, and a trouble-
maker as well. That is why I come back, for fun. Do not take
my crap personal, this is better than cable tv. "Rednecks" all over
the globe giving each other a hard time on the topic of chainsaws.
I will keep coming back to haunt you all, Darin willing.
