I'm really not sure what the image of the nasty looking spark plug is supposed to represent. If you are/were using synthetic oil and your spark plug looks like that, there are clearly other engine/maintenance issues going on. In any event, there are other advantages to using synthetic oil besides extended oil change intervals...even though most synthetic oil manufacturers will tell you to follow the OEM guidelines on when to change the oil. Aside from a few niche brands like Amsoil or Royal Purple, most synthetic oils on the market don't really push the idea of extended oil change intervals. Even though these are only basic/small engines....You're dealing with machines that are really only subjected to extreme conditions, the coldest temps of the year...an advantage synthetic oil has over dino oil. Especially when starting a cold engine. Also, these are engines that typically have no filter, with the additives synthetics have, your engine is better protected. The fact is, a quart of a quality full synthetic oil will cost you some where between ~ $7 - $9. Is that more expensive than dino oil...absolutely? But what's the point of penny pinching on machines that people are spending $1000, $1500, $2000, $2500+ etc on? Sure I'll buy an $1800 snow thrower but I won't waste an extra $3 or $4 dollars on a synthetic oil for it? That's ridiculous... imho I'm not implying you'll see a night and day difference between synthetic and conventional/dino oil...but there really is no advantage sticking with dino oil unless your intent is to save $3-$4 every which way you can. Unless the manual/OEMr explicitly says not to, you can't go wrong with synthetic...and change the oil when manual says to change the oil.

Spartan:
I do not agree with much of what you've said regarding synthetic oil.
The first point that I'd like to address is your use of the term "penny pinching" when in fact it's the wise use of one's money.
"Ridiculous" is spending 2 to 5 times the amount for a product that will NOT deliver any substantial gains over an equivalent but much less expensive product.
I've been working on small engines for over thirty years and I'm talking complete engine re-build on numerous OPE, motorcycles, ATVs, snowmobiles, outboard motors etc. I own in excess of thirty machines with small engines. Both two and four stroke. Therefore, I have plenty of hands on experience.
Since we're talking about snow blowers, I will give the forum a brief history of my use and ownership of same. I owned and operated two Craftsman snow throwers with 10 h.p. Tecumseh engines for more than twenty years. From day one, each engine was run on nothing but conventional 10W30 oil of what ever decent brand name for the best price. Both engines started and ran flawlessly, never needed any work whatsoever, and never used a drop of oil. Each engine outlasted the machines they were mounted on. So your suggestion that synthetic oil will provide additional protection is a moot point. If an engine can outlast the machine it's on, using conventional oil, why spend unnecessary money for an oil that will offer no rewards? That doesn't make any sense no matter how you look at it.
I've come to the conclusion that most die hard synthetic oil advocates have little or no experience with conventional oil. They've been sucked in by the promises and hype of synthetic oil when, in fact, there's no real need for it, in all but the very harshest of conditions or extended OCIs.
Now, some facts about the B&S Kool Bore engine on my snow thrower:
The engine has approx. 75 hours on it. The engine has 155 lbs. cold compression. The engine starts on the first pull every time and is very strong. I adjusted the valves and only the exhaust valve was very slightly out of spec. The engine is fuel efficient but likes to eat Mobil 1 5W30 synthetic oil at approximately 1 oz. per hour of hard use. It does not emit any smoke of any kind. It presently has Castrol conventional 5W30 high mileage oil in it and so far, I don't see any appreciable consumption although that's only after a tank and a half of fuel being burned under moderate loads.
I've also read accounts of other people having problems using this oil in their OPE. One person stated that his valves coked up so bad that he had to pull the head off of his B&S engine to clean them because the engine stopped running. He switch to conventional oil and all has been well ever since. It was that person's post that caused me to think about my engine using oil and to pull the spark plug to look for possible clues. You have seen what I found.
So, in conclusion, considering the apparent excellent health of the engine, what else could be causing the excessive spark plug fouling?
Once I get to operate the snow blower under some extended period heavy loads, I be able to confirm one way or the other if it was the Mobile 1 5W30 synthetic oil.

Borat: Short answer: I guess we’ll have to agree to disagree. I don’t think there is anything wrong with using dino oil, especially in a small engine. If you’re happy with it, use it. However, considering the cost of the equipment in question I don’t see the advantage in using inferior oil at the cost saving of ~$3. My suggestion is when you factor in the cost of the equipment and the cost/advantages of the oil, synthetic is the way to go. Long answer: I'm sure you have tons of experience working with small engines. You might be assuming a bit much with your "theory" behind die hard synthetic advocates. In fact, "I've" come to the conclusion that most people that down-play the virtues of synthetics are old fogies who are stubborn, penny pinchers, and frightened of change/new things/progression. See how easy that was? In all seriousness though... There are countless used oil analysis tests which substantiate the claims that synthetic is superior to conventional oil and we're not talking about extreme conditions or extended usage. We’re talking about typical conditions at regular oil change intervals. It's not even a matter for debate, synthetic offers real advantages over conventional in the over-whelming majority of applications.
Anecdotal evidence you posted aside, when you finally track down the real reason for your nasty spark, you might even want to try doing a UOA test one year of dino oil vs synthetic oil usage. Being as though you have 30+ years of experience, I know you’ll track down the problem. If you ever wanted to brush up on oil facts though you can browse the forums over at bob is the oil guy...just like this board has its own set of weirdo’s and true blue sources of genuine info, the same can be said about bob is the oil guy regarding motor oil. So the facts are: Synthetic provides better protection and in the over whelming majority of cases/applications synthetic oil is superior to conventional oil. To my knowledge I can only think of one OEM that prohibits the use of synthetic in some engines (all of which do not apply to snow throwers). I don’t think B&S, Honda, LCT, or Yamaha prohibit the use of synthetic in their snow blowers. So despite synthetic being superior you’re essentially saying there is no advantage in using it. My reply to you is even if the advantages for using synthetic oil in a small engine is positively minimal at best, when dealing with the maintenance of say ~$1500 + equipment it doesn’t make sense to use inferior oil at the cost savings of ~ $3. If we were dealing with equipment that cost say around $30, I’d see your point about the use and extra cost on synthetic oil. Finally, going back to this penny pinching term that you seemed to have issue with. In the grand scheme of things, saving ~$3 here and there isn’t what I personally would consider wise use of one’s money. Taking proper advantage of a 401k, investing in the appropriate stocks, mutual funds, etc over the course of many years is more indicative of wise money use. To each their own. Here is a very basic scenario to put things into perspective. Let’s say prices are constant and you changed the oil once (and used one quart every season) in your snow thrower. Now fast forward twenty years. $3.50 x 20 = $70 Your cost on conventional oil $7.00 X 20 = $140 Cost in using synthetic. So over the course of 20 years you saved a whopping $70 by using an inferior oil in your ~ $1500+ snow thrower. Ultimately I’m not here to convince you though. If you’re happy using dino oil…by all means use it. For some out-door equipment I have, (considering the state its in, age, cost, etc) I use dino oil too...or more accurately, I just use whatever I have available at that time.
My opinion/ 2 cents, considering the cost of the snow thrower, cost of oil and the advantages synthetic provides, synthetic is the way to go. Good discussion.
