Deere S140 Oil

@picklyrickly1073 You are unlikely to find a filter at Walmart due to the Fram bankruptcy and the fact that the 3614 is a popular size. You might find the M1-102A on the top shelf. If not the Carquest Premium at Advanced Auto is 85348.
Thank you! Is it a good idea to change the filter for each of those initial intervals? Say if I’m going to do at 1hr and 5hr. I will definitely be changing it annually with the oil but unsure on the earlier ones.

How reliable are those B&S engines you may wonder. Confession time: I purchased a similar John Deere mower with the B&S engine new in 2007, mowed with it weekly Spring-Fall and didn't change the factory oil FOR YEARS. :eek: The mower is now at my FIL's house and he uses it to pull a little yard cart around. The engine was abused badly by me, and still purrs like it's new.

@picklyrickly1073 I changed both the oil and filter the first time somewhere around 5-8 hours. For the next few years I changed both the oil and filter at the end of the season. More recently I've been changing the filter every other year because I average only 31 hours per year. That's sort of like changing the filter on your car every 2000 miles.
 
Walked into Walmart and found the last one they had for $3.50

Did an early oil change at 1.2 hours. Glad I did, gross! Refilled with T6 15w-40 and will change again at 5 and then probably oil and filter at 10 hours View attachment 336141

Okay, so you keep the oil and filters changed regularly I would like to add that no more than you will change them the cost is negligible compared to an engine swap. Heat is a big enemy of rings and valves. Also, the belt to the transmission is a pita.
 
On the first picture it looks like there is water or coolant in the oil.
There were some slight remnants of oil drained from my car just a few days prior, perhaps some condensation made it past the catch can and into the drain. This engine is not water cooled so would not be coolant.
 
I have a JD D140 and change the oil every year and the filter every other year. I have about 325 hours on it and everything works fine. I would run a 40 weight in it however it's hard to find at Walmart. I usually just put a full synthetic 5-30 in mine and it can be Kirkland, Mobil 1, or whatever I have on the shelf. Those engines are really good and generally outlast the mower.

Thanks, I did get a 15w-40 at Walmart. Mower ran fine with it, no surprises. Good to hear you have many hours on it, the transmission is a questionable part (TLT 200) but on my flat .3ish acre lot should be fine. It only took me about 30 mins to mow last time so 300+ hours is going to be many many years of service.
 
Recently, switched to 15W40 in my rider with a 15.5hp single piston Briggs & Scrapem engine. Has a double bagger on it, and it works hard on my 3/4 acre plot of grass. Engine doesn't even have an oil filter. It specs 5W30. The 3rd oil change I went to 10W40. Started doing that 4 yrs ago. Engine is more quieter now with the 15W40, and no significant additional fuel consumption. Mix Techron with fuel stabilizer in the gas cans to help keep the carbon buildup down. Also added an inline fuel filter with a shut off valve. Probably has about 250hrs on it by now. Going to install an hour meter on it one of these days.

I buy lots of 40-grade oil at Walmart.

I believe the TLT200 is a heavier unit than the K46 which is generally fine for mowing flat yards and not doing any work other than the occasional yard cart, so I think you'll be fine. For what it's worth, the K46 in my L110 ran until 700 hours before I sold the mower, although it was abused some. I did service it a couple of times which helped. Your transmission may have a filter that you can service? I read an article comparing it to the K46 saying as much but can't verify the accuracy.
 
Keeping the oil full, and changing it frequently (I usually say 50 hours for non-oil filter machines, 100 hours on a machine with oil filter) matters more than what oil/filter you run. 15w40, 10w40, 10w30 are usually my go-to, with 20w50 sprinkled in for those heavy oil burner machines.

I forgot to mention this earlier but it is important. Don't check the oil level on that engine until it has sat idle on a level surface for at least two days. If you check it too early you will be convinced that it is using oil and you will overfill it. My D140 doesn't use any oil at 345 hours.
