Ralphie ★ Posted May 25, 2022 Share #1 Posted May 25, 2022 Is it just marketing bs to assuage lazy consumers like me? Or is there some change to small engines that makes this possible? My suspicion is that Briggs and Stratton engines always have been indestructible so it is just marketing. I remember my dad saying a lawnmower engine would be happy with any oil it gets. In a similar vein, I was surprised to hear that my 86 (holy schitt, can she really be that old?) mother just changed the oil in her ancient mower. 2 Link to comment Share on other sites More sharing options...

jsharr ★ Posted May 25, 2022 Share #4 Posted May 25, 2022 Here is what B&S has to say. https://www.briggsandstratton.com/na/en_us/innovations/push-mowers/just-check-and-add-technology.html Apparently you change the air filter and add oil and that is it. They say they have done a better job of sealing the fill tube? Weird. I think I would still change it. Takes a few minutes to tip it on its side and then refill. Of course, if you are a dumbass like me, you overfill it and it kicks back and almost breaks your wrist when you try to start it. 1 1 Link to comment Share on other sites More sharing options...

Tizeye Posted May 25, 2022 Share #8 Posted May 25, 2022 Either B&S wants to sell more mowers as engine wears out faster Or you could just re-charge the battery rather than put gas in. Looking at B&S site, they don't market "no oil change" with any of their engines in the lawn mower section - just the "Innovation" section. Even then, relying on the air filter to keep oil clean would seem to be a recipe for disaster. What I did find interesting in the push mower section was the indication that B&S does both gas and battery-powered, but the comparison link just loops back to the same "choosing a lawn mower" page and no reference to a battery powered lawnmower engine anywhere. Comparing Gas & Battery-Powered Mowers Briggs & Stratton has the power needed to get the job done by offering a variety of options that include both gas and battery lawn mowers.

Road Runner Posted May 25, 2022 Share #19 Posted May 25, 2022 When I last was researching mowers, I noticed the "no oil change" thing, but the site I was on also said you could change it if you want.

team scooter Posted May 25, 2022 Share #21 Posted May 25, 2022 I'm thinking... I only changed the oil on my old walk behind Honda mower once after the first season. It lasted fifteen years until the deck rusted out. I dont even remember checking the oil, ever. Always started first pull. The "new one" is already four years old. I should probably change the factory oil on that. Luckily I got the plastic deck this time. Link to comment Share on other sites More sharing options...

You might be flying with 'no oil change' jet engines also. We would just add oil as needed plus send oil samples to a lab to check for excess metals in the oil. After a flight we'd bring out a couple of quarts of oil just in case for the jet engines. The piston engine guys would roll out a 55 gallon drum with a hand pump. The joke was that the USAF got rid of piston engined aircraft because the Russians developed an oil seeking missile. 2 3 Link to comment Share on other sites More sharing options...

12string Posted May 25, 2022 Share #28 Posted May 25, 2022 Ethanol gas doesn't gum up carbs, it actually cleans them. By loosening up deposits, which can then clog up the carb. But that happens when it's running, not sitting. StaBil does nothing to the ethanol, it does a ton for the gasoline. Ethanol in the carb is all evaporated long before your first spring start. The gas is collecting water and breaking down over the winter. 1 Link to comment Share on other sites More sharing options...

Technically, you are correct, ethanol doesn't gum up the carbs. Ethanol deteriorates the gas lines and that residue accumulates when sitting, then clogs up the jets in the carb, plus impacts the seals and rubber bladder if it has one. Had to replace several mowers and other lawn equipment even after rebuilding/replacing the carb which really gets expensive. Never had a problem since switching the ethanol free. The one pull first start tries not to work. Now, when first starting I remove and shake out the air filter and before I re-insert it, a quick blast of ether directly into the carb. Starts first time every time now. Link to comment Share on other sites More sharing options...

But the best storage is a full tank of ethanol free with StaBil. And I do keep ether around, usually only need it the first spring start. The boat is OK with ethanol, but it gets Stabil, and only a couple gallons in storage so I don't have to suffer through 45 stale gallons if that happens. I can dilute it It also gets Seafoam in the spring to clean up any water. Link to comment Share on other sites More sharing options...

Maybe because I think it is 7 which would be a lot if it was horsepower. One site says some small engine company, maybe Briggs and Stratton, was sued because the hp listed was a lie, so everyone started listing torque. My Craftsman M220 mower (picture at bottom) has torque on it, not hp. The motor is Briggs and Stratton. A lot of sites say, "You can convert torque to horsepower by multiplying the torque rating by RPMs of the mower and dividing by 5,250. Now you can compare horsepower to horsepower. The small print under the FT LBS Gross Torgue on the red label at bottom say 2600 rpm. 6.25 x 2600/5250 = 3 hp But the first table below says a 150 cc Briggs and Stratton has 4.25 hp. Note that 6.25 x 3600/5250 = 4.28 hp and the article the bottom table comes from says for Briggs and Stratton, "most of its series offer gross HP ratings at 3000 to 3600." So I guess I have a 4.25 max. hp that normally operates at 3 hp: it doesn't come with a throttle but would increase hp when it was cutting through stuff without losing to many rpms. It self-propels at speeds fast speeds but does slow down a little in tough grass. I've had a 6 hp lawnmower in the past and I don't notice the one I have now being any weaker. So maybe a lot of 5 and 6 hp lawnmowers in the past were listed higher than reality. Most people here saw the pictures of my yard looking like a wheat field in 2020 when I couldn't mow it because it was filled with glass and debris that hadn't been cleaned up from the fire. It was in growing the yard for months because of pandemic problems and landfill admissions problems in 2020. I needed to get down to about a foot high with a weedwhacker, then my current lawnmower did the rest moving very slowly and lifting the front end to munch chunks of grass - but it didn't want to quit. I had foot-high grass a few times between then and when I moved in at the end of June last year because of construction, etc. delaying me, and the lawnmower worked fine when I was finally allowed to get to it.

MickinMD ★ Posted May 25, 2022 Share #41 Posted May 25, 2022 Oil Change? You mean I'm supposed to change the oil? I got the mower from my BiL who picks up as-is small motor stuff from Lowe's, Home Depot, etc., for $25 or $50 and repairs it. So no manual came with it. I just looked up the manual for mine and there's all kind of lubrication I've been skipping. I doesn't say anything about changing the oil and there's no oil filter but a manual for a smaller Craftsman mower says to change the oil after every 50 hours of use.

Bikeguy Posted May 26, 2022 Share #47 Posted May 26, 2022 We have 2 Toro mowers (his and hers) that we used at our old home. I do change the oil in both mowers. One of the mowers is considerably older than the other. It burns oil.. I'm guessing the piston rings are nearly gone. Not much compression or hp anymore. After a few minutes, the catalytic converter is hot enough you don't see the cloud of smoke from the burring oil. Now the mowers are used for trimming around the trees and bushes. The JD tractor get taken back to the JD dealer once a year and I let them do all of the maintenance. It gets about 50 hours of use a year. 1 Link to comment Share on other sites More sharing options...

Lot of factors go into that price. I picked up a used 36" commercial walk-behind - it was not cheap, but it's a machine that's made to run 8-10 hours a day so it should last me forever, and it cut about an hour off the full-yard job. That's an hour I could be riding! It is a shoulder workout muscling it through turns though. 1 Link to comment Share on other sites More sharing options...
Kzoo Posted May 26, 2022 Share #49 Posted May 26, 2022 2 Things: 1 - Today's motor oil doesn't break down with age under use as legacy motor oil blends did 2 - We put essentially that same oil in our vehicles and drive 3,000 or 7,000 miles, sometimes under heavy loads. Any residential mover would need to be used for decades to get that same level of use. I check my mower oil level several times a year and change it about every 5 years. I have a snowblower that hasn't had an oil change in 15 years. I use it a handful of times a winter (maybe) and when I put it away the oil still looks fresh. 2 Link to comment Share on other sites More sharing options...
Longjohn ★ Posted May 26, 2022 Share #50 Posted May 26, 2022 A couple of my friends in high school had no oil change cars. They would just add a quart or so every time they bought gas. I think their engines were self changing the oil. There was always a puddle of oil where they parked. Link to comment Share on other sites More sharing options...
