Regarding engines you only have information gleaned from this forum and some guys in tech support and supposedly a Honda Manual. Funny thing is I didn't know the public library carried those. You cannot grasp the concept that car engines and jet engines are NOT snowblower engines. There is no evidence to support your claim that synthetic is better in snowblowers but plenty of anecdotal evidence from well respected members of this forum that synthetic is not a good thing to use in a snowblower. There are a lot of articles that detail out that synthetic oil is not better. But you choose to ignore anything that doesn't support your position. Why don't you stop trolling in this forum?
Who cares how long anyone has been posting in this forum? Just because someone has posted a couple hundred posts doesn't mean they can't be wrong about something. So bringing up the number of of someones posts in a web-forum and implying that gives this person some kind of credibility is a joke. I'd rather hear the "right" answer from someone who just joined rather than nonsense from someone who has 500 or 1000 + answers on a web forum. .
Also, this idea that ...

Who cares about anecdotal evidence and the anecdotal evidence/opinion about synthetic not being good to use in a snowblower? Show us, this forum, a couple of official/current articles published by Briggs & Stratton, Subaru, or Honda that say synthetic oil isn't good for use in a Snowblower/small engine. People care about what a product's manual says or an official statement from a company regarding their product. People for the most part don't care about anecdotal evidence and opinions.
Being as though Briggs, Honda and others sell their own "brand" of synthetic oil for use in their products (yes, including snow blower engines), I don't think they'd agree with the anecdotal evidence from random people on a web forum that say synthetic oil in a small engine is a bad thing.
In fact, this is what Briggs says about synthetic oil:

"SAE 5W30 Using Synthetic oil offers better wear control of your engine, even under severe operating conditions. Since synthetics have better "inherent strength" they have the ability to keep functioning at the highest level for the longest possible time.
Synthetic Oil gives your engine better viscosity temperature response, better low temperature fluidity, better thermal stability better oxidation stability, lower volatility, better deposit control, and better wear control.
This in return reduces risk of equipment failure, promotes trouble free operation, reduces maintenance costs, extends service life, and long term engine durability.
Briggs & Stratton's best engine oil, warranty certified, for all small 4 cycle engines. The use of this high quality detergent oil assures compliance with Briggs & Stratton warranty requirements regarding the use of appropriate oil."
I guess its time for you to tell us that these long time posters in this forum with anecdotal evidence know better than B&S about what kind of oil is better/best to use in a B&S engine.
