BX oil change.....

[gsxr1100]

I only use Amsoil HDD&M 15-40 in my BX and use the Kubota OEM filter. I also used it in my JD 455.

Oil goes in like clear and comes out like honey no matter what the hours are. Even in my old '97 Powerstroke with over 12K miles it came out very clear.

I do not go by color or anthing. Just looking at it I can't tell. I would get an oil test done to see. that being noted I will be getting one done on my next BX oil change and will post.

Oh, it cost about $5 for BX22 filter and about $15 for 1-gallon of oil.

3.5 quarts of new oil and reusing a filter is 3.5 quarts of new dirty oil. It's a $6 filter and a $10K tractor. That is basic hillbilly algebra and I love fresh apple pie.

I'll add my 2 cents here. First of all I've changed my fluids pretty much by the book for the first 3 years i've owned my BX. No problems other than things you can't really account for. Now I definately agree that if I'm changing the oil, I'm changing the filter as well. To me, it just doesn't make sense not to. But I think it may just be up to the owner. I've learned that in working on many different machines, most manufacturers recommend changing fluids more often than you really need to. Like trucks. 3000 miles to me is rediculous unless you really work it hard or tow frequently. But as hard as I use my BX I think it warrents changes at 100 hours. Less than that might be overkill, but you can't knock someone for taking care of their equipment.

Also, I like the idea of switching to Synthetic, till now I've only used my dealer's oil since they deliver to my house at no charge. But I'd like to see if using synthetic makes a difference.

</font><font color="blue" class="small">( What is the experiences of others with the BX engine... does your oil turn black after 50 hours of service? Does it stay visually cleaner with synthetic or dino oil? Does the color of the oil make a difference when you change oil??

Junkman, I don't have a BX, but on my 3 diesels (Ford Powerstroke, Kubota B2910, and VW Jetta) the oil goes in as described previously (clear) and comes out a light brown at the end of the interval. Sometimes it will be dark black. When I was running Rotella (Delvac 1 now in everything) it seemed to go black within the first 200-300 miles. Neither had bad oil analysis' so I don't think it matters, but there's definately a different in "Clarity" on the dipstick. (30 hours on the current batch of delvac and it's got a slight tint to it now on the 2910)

I have always been told that one of the jobs for oil is to keep the engine soot in suspension. Having black oil in a diesel would tell me that the oil is doing the job of keeping that soot from building up in the engine. I would be curious to know why some oils do not turn black. Are they leaving the soot in the engine? This is what I have heard by different people....may be a bunch of bunk!

Junkman,

It's a 1064 NAPA Gold filter. Wix makes NAPA's filters.

Just a couple of related ?s here. Some folks say that 95% of the wear on an engine comes during the few moments of starting, as the oil has drained from the cylinder walls and it takes a few moments for the pump to re-lube the walls. Those few strokes of piston against cylinder wall with almost no lube is supposedly where most of the wear happens.

A lot of truckers have pre-oilers to pump some oil into the head & let it start drippin' into the cylinders before turnin' the starter. Are there any pre-oilers available for CUTs & subCUTs?

Another issue some people make with frequent filter changes is that it can be hard to keep a new filter completely full of oil while screwing it on (unless the filter's oriented straight vertical). On the first crank-up after a filter change, a less than full filter (or, God forbid, you put a new filter on without any oil in it at all), it takes even LONGER before the pump is getting oil to the cylinders. Now they could be lubed some, 'cause you poured the new oil through the head, but still, the first few lubricated revolutions could be followed by a few rev's of fairly dry friction 'till the pump can get some more oil sucked all the way through the new filter & pushed all the way up to the top.

Any thoughts on these issues?

In my profession, I work on ATV's, motorcycles, outboards, etc, and have had enough opportunity to tear down engines for one reason or another. In 20 years of engine rebuilds, I have yet to see a "dry" piston and cylinder of anything that was run any time within a year. Very true that there isn't a lot of oil there, but they aren't dry. Unless you plan on running full throttle right away, engine lube at start up to me really isn't an issue. Even engines that loose their oil pressure from a oil pump failure often ruin the top end before the pistons scuff (OHC engines in particular). Even though this discussion is concerning diesels, these 4 stroke diesels aren't too different from what I work on.
I believe dirty oil is very responsible for accelerated engine wear. Oil has a "life span" and needs to be changed before it's up. That depends greatly on the conditions the engine is operated in.
The cylinders don't get any oil when you pour oil in through the head, as the oil just flows down a return gallery to the sump (oil pan).

OK, lets all be honest here, How many people have actually put oil in the filter (especially the side mounted ones) while changing the filter and fluid? I have been changing oil in many vehicles for the past 35 years, and observed many garages also. Never did it, or saw it being done.

I run Rotella in the 1800 and the Cummins. Change filter with it at 100 hours. Yep, turns black after about 50 hours. I think I'll start changing to a synthetic oil in both at about November strictly for its "flowabilty" during the winter.
