Indefinitely, keep the cap on it.Good to know. What is a the shelf life of synthetic oil?
My last Purolator did a great job, far as I know.The last new Purolator filter about cost me my Silverado engine. It had two stress crack in the filter can from the factory. I lost nearly 4 qts on a 40 mile round trip to a local town. And Purolator would not even honor their warranty so I no longer buy them.
this the triax you were looking for? https://www.amazon.com/Triax-Synergy-Synthetic-Compatible-EcoBoost/dp/B07YK1J3DGDang factory defect. Stress cracks from stamping the cup, they literally stretched the metal too much then they heavily painted over it. The paint held until the oil got up to operating temp. It happened right the oil change and no way my hand would have crack the filter cup. That could have been one heck of an expensive engine replacement.
Thanks to using Moly additive I was able to save the engine as the post should have read nearly "lost" the engine. My oil pressure was down to 20 psi going down the road after replacing the missing oil and bad filter. I had thought I blew a rear main seal but the UV dye traced the problem to the filter. Now the Moly has restored my pressure back to 50-60 psi going the road using 5w30 semi synthetic oil.
And no I am not running Slick 50. At the time I was using the 10W30 conventional oil the manual called for. Currently running Triax 5W30 API GF-5/SN, Synthetic Blend but it due for an oil change at 330K which just it passed. The problem is now that the Triax 5w30 isn't listed anymore on Amazon and I would need to switch 5W40 Full synthetic to keep the Moly additive.but $115 is not bad for 5 gallons.
Dog, you don't need all that fancy mega star extreme ultra grade oil mess. Just go to wallys and get some Supertech 10w-30 in that old hooptie. LOL Probably shouldn't be running that molly mess in a cat convert engine anyway. Let me guess, the cat/s are removed?Dang factory defect.

Hell no the catalytic convertor isn't removed. And I have been running the Moly in the engine since 2015 in that 2000 Chevy Silverado S1500. Considering I brought the PU when it had 180K and now has 320+K now I don't think it going to cause a problem.Dog, you don't need all that fancy mega star extreme ultra grade oil mess.

Tractor Supply sells Purolator brand filters in my area. Their blue filters are higher rated than the ones colored red, but they are all top rated.And a Wix/NAPA filter. Or a Purolator if you can get one.
I too hate wallymart. Only use them for motor oil. Can't beat cheapest price in town. Other than that, screw them. Most everything else is not a good deal anymore. They know it and raise their prices up. Other stores have similar or better pricing. Aldis Grocery here in OKC is AWESOME!!!Hell no the catalytic convertor isn't removed.

And as for Walmart I haven't brought a single thing from them in over a year other than my birdseed after they refused to my business sales tax exemption certificate. Kroger is getting all the groceries sales and Amazon is getting most of the rest of my business that would gone to Walmart. I know my $5K in yearly purchases doesn't matter much to them but it makes me feel better by sending it somewhere else.
Purolator makes a Tech version I think it's called. It's their workshop slash garage filter line. Says made in the USA, SHOCKED. I use them no problems. Couple bucks cheaper per filter. Better than any Fram.......Tractor Supply sells Purolator brand filters in my area. Their blue filters are higher rated than the ones colored red, but they are all top rated.
Thought molly was removed because of cat converts. All the good anti-wear junk like zinc and such. Poor flat tappet cams......Hell no the catalytic convertor isn't removed.

It is sad that the oil manufacturers don't know how to make good oil and people need to buy all of these magic oil additives to make their engine last. You would think there would be some type of organization that could test oil and see if it is good enough for a specific type of engine. It would be nice if they could put some kind of marking on the bottle showing what standards the oil met. But i guess we will just have to buy whatever oil and then buy some latest and greatest new and improved super duper oil additive to make it good enough. You would have thought that by now they could actually make oil good enough to not need to add stuff to it.
A little evening sarcasm to start an oil thread fight.??
That is so ancient !! Get with the program, Slomo.You guys not using Slick 50 are missing out. Don't even have to put any oil in the pan anymore. Sucker is so slick, when you turn the key off, the engine keeps running. At least another 80hp at the tire tread. LOL
I was given a 3/8" Sparta ratchet and socket set a LONG time ago. I still have it.Always fun to have "discussions" ? about oil or filters or spark plugs or fuels. At least they are more civil here than the ones on Arborsite. Some of those guys bring weapons. ??. On one forum i thought two guys were really going to fight it out over who made the best hand tools. Got to love the fanboys.
My mom worked in a factory making off-set screwdrivers. At the end of the assembly line was a stamp. Sometimes that stamp was fitted with "Craftsman", sometimes "General", sometimes others.I was given a 3/8" Sparta ratchet and socket set a LONG time ago. I still have it.
Back then, Sparta was considered one of the cheaper tool brands on the market.
I doubt if you can even buy one of equal or better quality now.
Let the mud fly.
Back on topic: All oil is good; some is better than others. My brand is better than your brand.
I would like to think, buying Kohler oil, it would be formulated for their engines, regardless who makes it. They put their name on it so any failures would look bad on their part.First of all, Kohler doesn't make oil, synthetic or fossil, so buying Kohler oil is just adding a mark-up on the price.. 300 hours isn't a long time, I think I'd be OK with that because syn. oil does not break down. Years ago a test was performed with Mobil 1 vs standard Mobil oil using NYC taxis. I don't remember how many miles they got on the regular oil before lubricity failed due to molecular breakdown, but the test was stopped after 1 million hours and there was no change to any of the measured parameters of the Mobil 1. I've stuck with synthetics ever since. Remember, every time you use a wrench on any machine you introduce a failure mode that didn't exist before, such as a filter with stress cracks. For that reason I rarely perform any maintenance early.
If you know what the specifications are for the oil, such as the API service rating or any other special additives that need to be in it, then any brand of oil that meets those specifications should be fine. If you do not know the details of the specifications, then I would follow what the manufacturer suggests to be on the safe side, especially during the warranty period.Reading through the 2021 manual, the B27i is now coming from the factory with Full Synthetic Kohler Pro 10W-50 motor oil (the engine is a Kohler 27 horse fuel injected model). The specs say you can go 300 hours between oil changes. The filter plus 2Q of oil are being sold at Tractor Supply for $45.
What are everyone's thoughts on following those recommendations?
Yea My Son's blazer blew the rear seal. It had slick 50 in it, made it 200 feet before the 4.3 locked up tight on mains & spun. SNAKE OIL!You guys not using Slick 50 are missing out. Don't even have to put any oil in the pan anymore. Sucker is so slick, when you turn the key off, the engine keeps running. At least another 80hp at the tire tread. LOL

i had Kohler CV16 with hydraulic lifters, i changed the oil with Castrol 10W30, lifters started ticking. Went back with Kohler Synthetic blend, 10w30, lifters stopped ticking.I would like to think, buying Kohler oil, it would be formulated for their engines, regardless who makes it. They put their name on it so any failures would look bad on their part.
300 hours is roughly 12 times more than a typical push mower sees in a season. Push mowers hold less oil than a 0 turn. Plus 0 turns mostly run filters. Still these are air cooled and run pretty hot. It takes about a minute to reach full operating temp.
So called synthetic oil will break down just like dino oil. Don't know where you heard this misinformation from. It's not so much the base stock but the additive pack is what suffers. Every oil out today has some form of additives.
That Mobile 1 test was a sales gimmick. 1 million hours......... COME ON MAN (Sleepy Joe Biden). Won't even go into that so called "test".

That wasn't lifter ticking. It was a blown head gasket?i had Kohler CV16 with hydraulic lifters, i changed the oil with Castrol 10W30, lifters started ticking. Went back with Kohler Synthetic blend, 10w30, lifters stopped ticking.
I have a 1/2" ratchet i got from my father wben he worked as a millwright for the CCC during the depression. It is Indestro Super brand. Beats the crap out of the Crapsman ratchets i have.I was given a 3/8" Sparta ratchet and socket set a LONG time ago. I still have it.

As you found first hand, Castrol is NOT what it used to be. Now days it's at the bottom of the pile.i had Kohler CV16 with hydraulic lifters, i changed the oil with Castrol 10W30, lifters started ticking. Went back with Kohler Synthetic blend, 10w30, lifters stopped ticking.
The b27i is a Walker zero turn with a 27 horse, fuel injected, Kohler engine, not a push mower. Does that change your analysis?I would like to think, buying Kohler oil, it would be formulated for their engines, regardless who makes it.

Synthetic oil is in Vehicles, can go 15,000 miles or longer. In a Lawnmower could be once a year or longer. I have it in all of my equipment.Good to know. What is a the shelf life of synthetic oil?
Really ?Rather than change my oil at specific intervals, I use an electronic oil tester. (You would be surprised how long oil can last based on actual measurements). This is similar to what I use :

You have absolutely no idea what your talking about. The device measures the levels of acidity, carbon depositis, moisture and a few other impurities. And it works, no matter how little you know about it. Silly nonsense babble.Really ?
Suppose you have a miracle milage increaser as well.
That do-dad simply measures the resistance of the oil and is a joke.
They have been pulled apart dozens of times
Nothing more than an electrode pad with a variety of connections & some refference resistors .
Dancing naked at midnight around a beaker of used oil with a stick on a string would be about the same accuracy.
Oil gets changed at the end of each season.
Actually taxis engines have a fairly easy life because most are on the road 24/7 and the engines rarely cool down completely .You have absolutely no idea what your talking about. The device measures the levels of acidity, carbon depositis, moisture and a few other impurities. And it works, no matter how little you know about it. Silly nonsense babble.
Changing oil annually is only a precaution, like preventive maintenance. Granted, it can pick up moisture over the winter but even that shows on the tester. Oxidation is less of a problem than people think.
For whatever its worth, taxicabs routinely use oil monitoring and not specific intervols for oil changes. (And that's some of the most severe use on the road.
I was going to point that out, too. Anytime you see claims being made about '24, 48, or1046 hour "torture" tests', be suspicious. That is the easiest duty an engine can see. It's "surviving" ONE thermal cycle.Actually taxis engines have a fairly easy life because most are on the road 24/7 and the engines rarely cool down completely .
If you only hand-tighten the oil filters, like they instruct. they should come off with out too much effort.
If not a strap wrench helps.
Nope, not at all.The b27i is a Walker zero turn with a 27 horse, fuel injected, Kohler engine, not a push mower. Does that change your analysis?
Umm, okay. Guess you could run Wesson Oil for a million miles too. That 15k or 25k miles per oil change is a SALES GIMMICK. Might call your favorite brand of oil and inquire about them replacing your engines. See what they say on parts and labor.Synthetic oil is in Vehicles, can go 15,000 miles or longer. In a Lawnmower could be once a year or longer. I have it in all of my equipment.
You change oil because it's dirty. Not at 25k miles or sampled from a lab.Rather than change my oil at specific intervals, I use an electronic oil tester. (You would be surprised how long oil can last based on actual measurements). This is similar to what I use :

Keep stretching the numbers. I don't get it........ A 0 turn holds what a quart and a half? Some maybe more? Push mowers like 18 whole ounces?300 seems kind of short for synthetic....? Id keep tabs on the condition of oil. FI engines are very efficient..... id think more like 500 honestly....
Agree Bert, Oil IS the cheapest part you can put into a motor.(snip)
as another riding pal used to say
"Oil is the cheapest part you can put into a motor"
In my experience, the manuals normally tell you what viscosity of oil to use as well as any other specifications that may be required. For example, if it says the oil must meet API SJ, then I look for that on the oil container. If the container says it meets that specification, I am comfortable using it and I have not had problems to date.My thought is that I would have to contact Kohler directly. But I didn’t read all the literature that came with the Walker yet. I was just trying to accumulate the oil, oil filter, air filter, fuel filter, etc that I would need in the first 2-3 years of ownership.
Would the oil specs be in one of the manuals? And can one trust the specs provided by oil manufacturers?
