A lawnmower that doesn't require an oil change?

What is this voodoo? They design it to just burn oil?

The new EXi engines series from Briggs & Stratton makes lawn mower oil maintenance easier than ever. With improved air cleaner seals, cooler engine temperatures, and high-precision manufacturing along with regular scheduled mower maintenance, the company’s new EXi series lawn mower engine is the first that never needs an oil change.* While the EXi engine requires that consumers need to only check the oil level and add as necessary, regular scheduled maintenance must still be performed.

Thats interesting.

My dad never changed the oil in his. He just added. Other stuff would make the mower trash before those engines would give up.

Some heavy duty engines have systems designed to consume oil so you never have to drain it. That tech has been around. I didn't know anybody could still make it work with new emission standards though.

I'm looking for a new mower but this seems strange. I can work on engines but if this has some strange technology that I don't understand, I probably won't buy it.

It might just have really good synthetic oil in it. I doubt it has oil consumption equipment. That really doesn't work any more since we have emissions laws.

Same here. Had a Craftsman with a Honda motor. I abused that thing. Something gave up on it a couple years ago. Couldn't get it to fire back up, and I had been cutting the front lawn. When I tried to crank it for the backyard it wouldn't do anything. I just bought another one and sold the other for parts at a garage sale. I'm sure the old man got it working again or scavenged what he could off of it, but push mowers are pretty much disposable after about 7-8 years. If I paid for a nice riding mower I'd worry about maintenance more, but something under $200, just run it until it dies.

might as well get one of dem electric fellars.

Not anything I've ever seen other than 2 stroke systems. Many are designed to not need oil changes provided they do not overheat except during overhauls but routine maintenance often consists of supplying additives that enhance desired viscosity and cleaning characteristics. There is also almost always an external oil reservoir, external pre/post lube pumps, and electronic monitoring. None of which would translate to a lawn mower.
In reality, you typically change the oil very frequently for the number of hours you put on a lawnmower engine. Most of that is to try to mitigate the issues presented but how dirty of an environment you are operating within and the temps you reach in most air cooled engines.
these things are probably an indicator of the main reasons you can skip the oil changes

And I suspect that after x hours (probably the equivilant of 7-10 years of operations for 1 - 2 hours weekly for 6-7 months a year) they recommend an oil change.

The better filtration and sealing of the engine are probably the biggest contributors. Seems they've taken steps to improve the cooling, bore finishing, and piston coating too. Lawn mower engines typically don't need the same requirements of automobile engines, most of the oils used are vastly over-engineered for small engine use and seasonal oil changes a probably wasting perfectly good oil for most users. Given how many automotive transmissions are now fill-for-life I'm not surprised about this.

The Cummins Centinel system comes to mind. I think caterpillar has a similar system. Again, nothing you would see on a lawn mower.

It literally takes 5 minutes every 2 years to change the oil.
Just a gimmick to get more $ out of your wallet

i had one of those $100 murray's with a b&s engine. never changed the oil, just added some every now and then. lasted for years.

Some oil is always being consumed in any 4stroke.
I'd bet they went to a single ring design. Slightly increased oil consumption coupled with an increase in power.
It's the same thing people do to the "new" short skirt piston high revving motocross engines.

I've never changed the oil in a lawnmower. Ever.
Just check the level and add when low.

Are you saying people don't change the oil in a motocross bike? I change mine every 3 hours of run time or after a race. Most people I know do about the same.

Look at all the gov't mandated emission and safety shite on that new mower when all you really need is this.
