Removing dirty oil from oil cooler and lines

PS Dave, I am going to try and make a record run up to Denver in my car next week, lol. My son lives in Denver and drives an STi Launch edition. Just going up to hang out with him.

Sunday April 5th is an open lap day at HPR:
http://highplainsraceway.com/

Weekend of April 18th is Rocky Mountain Vintage Racing (RMVR.com) competition drivers school at PPIR (south of CO springs).
They also have a "Performance Driving school" open to anyone and their street car.

Are you purposefully or just accidentally obtuse? This is a twin forum, not a Porsche forum. We're not talking about your car; we're talking about twins. The question was about a twin's oil cooler, something a bit different from your VW.

And you of all people calling somebody a thread police officer? You're the ultimate pedant of the forum. Congratulations.

I was responding to the people who commented on WHY I feel the need to flush MY OIL cooler.
Are we no longer allowed to respond directly to questions if they are slightly off topic?
WTF are you the thread police??

Actually, Stu is very acute. Read the original post. No one said anything about specific platforms. The objective of this thread is removing oil from the system.

Dave, thanks for the info on track events. May just take my helmet up there. We have been to PPIR several years ago but I haven't been to High Plains.

Seriously? How much more clear do you want?

@stugray just answered OP's question. He didn't bother with the typical "don't waste your time doing that" response as he didn't know OP's circumstances. If OP wants to do it he now has an idea of how, whether anyone else here feels he should or not.

@Clipdat

Here's my reasoning:
1) I didn't realize that Mishimoto ONLY caters to the FR-S/BRZ platform. Apparently they do, so all of their products may just be completely proprietary from every other platform.
2) Oil coolers are a new technology. Our platform is the first to ever have the possibility of being equipped with one.
3) The principal idea of a "core", some "hoses", and some "fittings" can never be related to any other product that is damn near identical.

Now all of those sound ridiculous right? I'm not trying to defend anyone here. I'm also not trying to troll or start any unnecessary arguments. I'm just trying to both use and show some common sense. The oil coolers on our cars can realistically be used on almost every other car out there. How the oil gets to the lines prior to the core may be a little different, but they all function EXACTLY the same once you get to the fittings Stu gave his method for his car which also happens to have a "core", some "hoses", and some "fittings" (who would have flippin guessed!). His method worked for him on his much larger system. I do not have an oil cooler, but am grateful that he posted that. That is something I learned and is something that I will eventually be able to apply to more than just oil coolers. Why more than oil coolers? Because I have common sense and understand the principal of removing fluids from a few feet of hose.

If you still think that what he said is bullshit, then you truly are an ignorant individual, and that must be bliss.



This forum amazes me with all the ways people get problems solved. Yet at the same time, it disappoints by how much others don't want to accept new ideas. I'm referring to real things that are actually beneficial for the entire automotive community, and not light up spoilers yo!

Not that it matters to jsimon, BUT.....

I wonder the same thing as when I did the last oil change I undid the bottom hose on the 19 row cooler and drained it out to find it had 900 ml of oil in the system.

This was more than I thought it would have and nearly a liter of dirty oil staying in there and mixing with new oil doesn't really sound good.

Had a bit of trouble getting the line onto the sandwich plate to seal again so might try compressed air to gently empty the system next time.

It's more then that, it's like 20% of your oil. Personally I don't want to change my oil and leave that much dirty oil in the system.

Think of this quantitatively. Let's say on a standard 5qt change on a set interval you use up 80% of an oil's additive pack. When you add an oil cooler, all that oil that doesn't come out is additional capacity on top of existing capacity. Let's say that adds a quart of oil. On the same oil change interval you'd only be using 66% of the oil additives in all the oil if you were to change all 6 quarts. Unless you were planning on stretching the oil change interval to use up the additive pack more it's not really worth it. You don't even need to change the oil sooner.

What makes an oil "dirty" is when the additive pack gets consumed and particles go into the oil. The filter catches anything really harmful anyway, and you are still draining out 80% of the tiniest particles the filter can't catch. When you mix in new oil, the new additive pack blends with the "old" oil and what you are left with at the end is 6qts of oil that's slightly used. It's a hassle that's not really worth doing when you realize there's not really a point. It's not as if that quantity of oil that's in the oil cooler will always be there and sludge up eventually. It blends

[boredom.is.me]

But over time, wouldn't that extra capacity run out? I don't feel like doing any math, but that 80% to 66% of used additives only really applies to a COMPLETELY refreshed system. At some point you will want to completely flush the cooler as well. That would then again refresh the amount of extra capacity within the system.

I mean, that's a really good way to look at it, but maybe every third or fourth oil change should be a complete flush right?

With thinking like this why don't we all change our oil and just put in 4 1/2 qts of new oil, and 1 qt. of used oil. Think of the money we can save...

Not really, because every X miles you replace Y amount of oil which contains Y amount of new additives. It doesn't matter that there's extra older oil still there. It may be a lower concentration of it per volume, but the quantity of it doesn't change

I mean if you wanted to you could, as long as you shorten your oil change interval to match. You could also only change 1qt of oil every oil change if you wanted to, as long as you changed your oil every 1000 miles on the dot. My thinking like that isn't to save oil or money, it's the large amount of time and effort. It doesn't take a whole lot of effort to put in 5.5 qts of new oil over 4.5qts + 1 old qt. However to change 6.5 qts as opposed to the regular 5.5 qt drain? Shrugs.

All I'm giving is a reason why you don't have to. If you don't buy it, change all the oil and drain every last drop of it. It's not going to hurt your car obviously, you just have to spend the effort, and it doesn't make a difference to me.
