Fluid extractors for oil change

[bryanchurch06]

I changed oil today with a fluid extractor taking out the majority of the oil with maybe 4oz in the drain pan, after I finished the local expert on everything came over and said I made a mistake and had left gunk in the engine. His explanation was the drain bolt hole allows the oil to carry any gunk out with the flow and by not doing so I was leaving crud in the engine. Any thoughts?

I wouldn't go so far as to call it a mistake. There is no doubt you have more dirty oil and debris left in the engine. Is it enough to really matter? I'm a clean oil freak so I wouldn't use that method unless there was no other easy way to do it....but thats just me

use the drain plug. thats what its for. what gave you the idea to syringe it out?

 

[bryanchurch06]

The place I'm at is very picky about what is spilled on the ground, and discourage changing fluids in vehicles. I searched for the cleanest way and found many videos on vacuum fluid extractors and singing the praises on them. Next time I'll ride out to the desert and drain it into a pan, if I spill any i will throw sand on it and forget about it.

To be clear I removed the drain plug after vac and drained the leftover oil the vac missed, about 4oz

Is this the first service oil change? How many miles on the oil? Did you change the filter too? When do you plan on changing the oil next?
I think those are all important context here on whether or not it's a good idea. If you're doing this between the recommended service intervals, then it's better than not doing it as long as you don't melt that syringe hose inside the engine. If you're substituting this for a regular oil change interval then without the gravity-drain effect it's likely leaving more crud behind than doing it the recommended way. That syringe isn't doing the same thing as an oil extractor that would be used for automotive, marine, or big diesel oil changes. Those run more vacuum and depending on the engine, if you pull the drain plug after running one the correct way there won't be a single drip out the plug hole. They also start the extraction from a low point in the engine, so they have the whole oil volume moving toward them for extraction which is similar to the effect of draining vs sucking oil off the top. If it's the first service, there's going to be more "crud" from the manufacturing process in the oil where I'd personally want to "drain" as much of that as possible.

There are 3 places on your JA65 engine designed to catch and retain crud: 1) oil strainer screen right above the drain plug, 2) oil spinner/centrifugal filter, 3) oil filter. Just keep those in mind and don't neglect them. Even with the JA65 Honda still recommend pulling the crankcase cover once you get way up there at 8k miles to clean the centrifugal filter and strainer screen.

Cardboard boxes are my free go-to for not spilling oil on the ground. Free and often plentiful. If you're working at ground level they also make for a more cushioned surface to lay on top of than gravel or concrete. If you've got a smaller catch pan where you are worried about positioning it for the path of the oil flow or oil soaking through the cardboard, you can use a baking sheet as a secondary catch tray. I've found used and abused baking sheets at Goodwill for just a few bucks and they're a handy for that or as parts trays.

1st change about 100 miles on engine, oil was very clear

Bryan, to my mind it’s a moot issue. Certainly on the JA55 the stated oil capacity is 900ml - but remove the drain plug and only 700ml comes out leaving 200 potentially containing debris elsewhere in the engine!

Now, please get back to your allotted task of sorting out tubeless tyre conversions …

Whatever you do just do not over torque the plug- something I wish I did not have first hand experience in!

It's seems I've been appointed the test dummy for tire conversion on this site

get a cookie pan put it under it. also,a blue tarp.

back in my 20s... coin op car washes were my go to. lol. I changed a few clutches in them.

Thanks for all the feedback, the extractor was the method the park owner was most comfortable with, I should add that it's very windy here, winds are almost blowing from 5 to 20 mph with occasional gust 40 to 50 mph. I cannot put my rv awning out most days for fear of its blowing off. The owner mentioned that as one of the reasons for stopping fluid changes, to easy for a gust of wind to catch your cardboard that your pan is on and flip it over. So as I stated earlier my next change will be in the desert and if I spill any while transferring it to my used oil jug I'll bury the evidence and keep my mouth shut. I will state for the record I was surprised how much oil the pump removed.

ahh you're out int he wilds so to speak, that makes more sense.

Only because it'd overcomplicate this and those solutions make m in sc happy to hear, but I thought you could attach a hose to a Fumoto plug. So Fumoto + a drain hose into a closed container could be a very, very slow way to drain the oil without being affected by wind.

its great idea but don't those hang kind of low vs the skid plate?

Isn't there a thread on those somewhere here? Anybody use one?

 

[SneakyDingo]

There is a thread, but I don't think anyone admitted to using one. I think that thread is also so old that it would apply to the JA55 too. I'd be interested in this:

vs the after market skid plates available.

The one I'm using has a large cutout for the oil drain
