Will this oil filter fit my kohler?

Penzoil PZ-21.

25 HP kohler in DGT6000. don't know off the top of my head if it is a Command or a Command Pro. Judging by the pic on the web, it is a plain old Command.

I was doing the Wix look up, but not sure it fits my engine.

BTW, this was the replacement filter given to me for Briggs 21hp intek by an authorized Briggs and Stratton dealer.

Go figure.

we use the kohler command filters both reg and compact ones interchangable with the Briggs oil filters ...no problem. actually pretty good to have this among engine manufacturers. Why not use oem insted of wix? We sell oem kohler filters for 7.50.

Thanks Neil.

The reason I was asking about the Penzoil is because they are quite available where I am for about $6 canadian (that's about a buck and quarter US).

The Wix filters are harder to come by. I stopped by our local autoparts store and they assured me they had no Wix filters for tractors ... personally I thought the guy was an idiot since he didn't even look the part up.

BTW, OEM (Briggs and Kohler) filters run about $18 canadian (that's about a buck and a half US).

I believe I heard that NAPA Gold filters are actually Wix filters. Is there a NAPA in your 'hood?

Neil, will you set me up with a package deal for a few plus a set of Kohler gloves? :D PM or post here with the pricing options you have for filters. I need some for my GT5000 25HP Kohler

Thanks
Andy

NAPA Gold 1348, for the 25hp Kohler

The NAPA gold 1348 is the cross for the WIX 51348 that is the direct cross for the Kohler 52 050 02 as per the Wix site and the cross ref. on the NAPA Gold 1348 box crosses back to the WIX 51348.

My last one was under 6 bucks.

I am on my second NAPA filter with no issues to report.

25hp Kohler pro, Craftsman GT5000 on its second season being in Dallas running straight SAE 30 also with no issues to report at about 60 hrs on the machine.

MGM - Why are you running straight 30W oil instead of the recommended 10W-30?
I though I read some one cautioning against 30W due to the type of hydraulic lifters in a Kohler engine.


Thanks for your 2-cents.

What about this filter...

I too was due for my 5 hour oil change. So I went to the auto parts store tonight to get an oil filter.

I took the WIX #51348 cross reference since I was going to Autozone (nappa closed) any way came up with the following additional cross references:
Fram TG3614 or
Purolator L10241
AC Delco PF53

As I was checking them out I thought I would try to find the 'longest' filter that had the same base size and threads as the one above. I matched base size, thread type and count and the number of drain back holes and placement of drain back holes. I found:
Purolator #PL20252

I thought that the longer filter will give more oil volume and all
the benefits associated with ... cooler oil, longer lasting between changes, better filtration from more filtering surface area etc...

I have the clearance on the tractor (DGT6000 with 27 HP Kohler) and I'll check this weekend before screwing it on real closely. I'll also check the oil level and keep track of how much I put in total.

Question is - If it all matches up and spins on fine is there any reason NOT to use the longest filter that will fit the tractor?

The stock filter measures approx. 3.5"
The longer one measures approx. 4.75"

Seems just like stepping up from the short Kohler to the 52 0502 only taking it one step longer.

What do you guys think?

"Why are you running straight 30W oil instead of the recommended 10W-30?"

>>>>--------------------------------------------->

10w-30 is not needed where I live.

10w-30 is "recommended” by Kohler themselves for temps down to 10 degrees f, -20 degrees C. My operating temps are no where near that cold and are closer to the upper end of the range where the 10w 30 would be getting close to being 30 anyway at 50 to over 100 degrees f as it is here in Texas in the mowing season (no snow work here).

I am well aware of the lifter issues and the valve push rod bending issues reported to be caused by heavy single viscosity oils.

Also I have seen the waxy residue left in engines by using multi- viscosity oils when there coils that make the oil multi-viscosity breakdown and create a wax like slug in an engines oil gallies.

I don’t want that stuff in my engines, any of them no matter who says to put it in there, I have been running 30 through 2 seasons now in my North Texas Kohler Engine with out any signs of lifter or push rod problems, no clicking or clacking.

The last oil change at 50 hours was a bit darker yet clear and flowed freely out of the engine. This time next year the engine will be out of warranty.

I am not running a viscosity outside the recommended oils range I'm just not running multi-viscosity oil and I feel better doing so not having the non-lubricating additives that make multi-viscosity oil work in the engine.

I have been running the same oil in all my engines for 3 decades with no oil viscosity related problems ever.

Bottom line is, I trust it to do its job and do it well in my climate.

I hope this helped show why I run single viscosity oil.

I use straight 30. I'm in near 100 degree weather so I don't think it's an issue. No snow blowing here!!!

Thanks for the insight about multi-weight oils. I had not considered the potential downside of what makes a multi weight oil work and I agree that the operating temp range justifies the oil selection. I mow in Alabama and our days are easily @ 90 degrees or above.

May I ask what brand of oil you run?


What about the larger oil filter idea?

You say the threads match up fine, so you should be OK on that count. But I think you need 8-11 psi bypass valve.
I did the WIX comparison of your PL20252 = Wix 51342.
The wix comparable is 16 psi bypass valve.

Not sure what the ramifications may be, I'm sure someone could shed more light.

Good luck.

Asking about brands of oil is like asking questions about another fellas mother!! Your gonna get a lot of opinions and some are gonna be heated!! I'm just pop some corn and watch...lol

Be careful....filters are also equipped with relief valves in some cases or not...........if it needed a longer filter..Kohler would have one. Just use the one called for by Kohler...........with the recommended intervals.....your not going to go broke.Usual problem for these engines in NEGLECT and no oil maintenance at all!
Why put a cheap filter on a $1300+ twin Command? :eek:mg:
There can also be a wide range of differences in the filter media INSIDE as far as quality and amount of surface area.

btw..we HAVE experienced running probs with customers using straight 30 wt oils. we buy Kohlers oil by the pallett and sell in store a oil/filter change kit . one oem Kohler filter (or kawasaki) and 2 quarts kohler command 10-30wt oil for $9.99.

our customers are strongly encouraged to use during warranty period.....gives a leg to stand on if there are ever any potential issues there.

OK - I officially withdraw my "what kind of oil do you use?" question. Did not think about that ones potential for debate - sorry.


As for the filter - Thanks for the info on the bypass valve PSI difference. That is why I asked - hadn't thought of that. I think I had late night 'parts store madness' that is where one is tired and these great ideas come to you while in the isle shopping.

If I drop the 'longer is better' filter idea and stick with the stock length - can you tell me what the WIX bypass PSI on the Purolator PL10241 is?
(this was a cross reference to the WIX 51348)

I bought both filters in case the longer on did not pan out.

Thanks again for the help.

The NAPA Gold 1348 has a bypass valve pressure setting of 8 to 11 PSI. This is also the same for the WIX 51348

Most engine issues I have heard about with single vis oil is in temperatures at or below freezing. I am not advocating the use of single vis oil in situations where it is needed to keep proper flow, but that just is not the case here for my machine and I have seen no problems or had any of the issues I have been told I would have, they have just not happened.

If you are worried about the warranty issue don’t run single vis oil.

I run Pennzoil HD-30 in every engine I have and always will as long as they make it.

And one other note the larger air cleaner used in the Kohler Pro in the craftsman tractors is a match to the NAPA Gold 2444, not sure on a pre cleaner.

I appreciate the look up on the bypass PSI.

It occurred to me that if I want higher oil volume why not kill two birds with one stone and install an oil cooler. That would get a little more oil volume and keep the stock filter settings while
adding the cooler benefits. heck - might even install a temp gage or pressure gage also. Funny how all that probably is not needed but also wouldn;t hurt if installed right. Guess the tractor is replacing the old hot rod in the 'what's next' bolt on accessory in my family.


I appreciate your info on the oil - think I'll run the multi for now. I have an older craftsman the has a 12.5 Tech. engine that runs straight 30w. Maybe I'll switch once the engine gets some hours on her.

Thanks for the air filter info. I bet that save some $ over getting it from Sears. I think the prefilter can be cleaned and reused a few times.
