Rotella 5W40 in a Tecumseh

For your snowthrower and its oil the feeling is the same...if it is minus 40 with wind or not...it only maters for you

My Tecumseh powered snowblower was doing the same thing, I did a few piston soaks with sea foam on a warm engine and it cleaned right up. I think the rings were a little sticky from the 20years of neglect it went through before I got it.

BTW I'm running T6 in mine and it's been going strong for 3 years of hard use since I acquired it.

I think it might be a common issue with these? It's got a really course piece of foam where the breather tube connects to the airbox to catch the vapors. First one I've ever seen.

For what it's worth, I'm a fellow Wisconsinite and run T6 in everything. My lawn mowing/snowblowing tractor with a Briggs Opposed Twin, my Horse tiller, powerwasher, generator. Well, you get the point....

I don't have a huge amount of science to say why, other than using HDEO in small engines was the consensus on BITOG several years ago when I was researching it. It's worked for me, and I'm at the point where I don't see a need to change.

And in reality I can't, because in true BITOG fashion I bought out Menard's stock of T6 when they were clearancing out SOPUS products a few weeks ago. And they had a 10% rebate on top of that. Score!

T6 is good stuff, no doubt. And the 5W40s are the most versatile of all the 40 weight oils ... they cover the greatest temperature extremes … and I doubt you'll shear one down short of an abusive torture test.

But if your OPE engine is a bit marginal for the application I'd still recommend an XW30 (perhaps T5?) over an XW40 ... unless it uses a lot of oil and a 40 weight is a must.

My 28" Ariens snowblower has a 250cc B&S OHV engine. It gets the job done ... but just barely. My Dad has almost the same blower ... but it is a bit older and has a 350cc Tecumseh OHV engine. It's extra power is extremely useful when you have to throw the heavy stuff.

It doesn't transform the machine, but I run a 0W30 HDEO instead of a 5W40 in mine and I will continue to do so until my machine begins to consume oil. I predict this will never happen in the time I own it.

"For your snowthrower and its oil the feeling is the same ... if it is minus 40 with wind or not ... it only matters for you"

For an inanimate object, this is correct. For a living creature or an internal combustion engine, wind chill factors come into effect. An engine running in the wind will run cooler ... so will a person who is running (or walking, standing, etc ... ) on a windy day.

As for temperature at start-up, it will not matter ... unless the sun is out. The wind will strip away heat provided by the sun.

This really depends upon the air flow over various engine components with or without wind. In some cases the air flow over the hottest components will be determined by a cooling fan, and in other cases not. This all depends upon the design of the equipment. If there is a cooling fan in the equation, the the effects of wind chill will be negligible.
