New Car Oil Flush?

[SF0059]

I am thinking about doing a short drain on my Odyssey. It has about 5k on it now and the OLM reads 30%. I am thinking about draining it at 20%, putting in some Valvoline Syn and running it to 10% then filling with TGMO. I already have the Valvoline which I got on sale. My purpose is to try to flush out more of the break in crud before the first true OC and subsequent UOA.

Thoughts? Am I crazy or is this a good idea?

No need to flush, just do oil change with Valvoline Synpower when OLM went down to 15-20% then change to TGMO when OLM went down to 15-20% again.

Yeppers, but the thread title doesn't match the OP since that's not really a flush. Just changing the oil a little early.

You've already taken the FF too long, might as well take it down all the way!

 

[SF0059]

Yeah, sorry about the wrong terminology. I just wanted to run the Valvoline between the 20% & 10% mark.

To the reply stating I have taken the FF too long, Honda uses a break in oil and states it should not be changed before 30%.

Thanks for the help guys, I don't feel as crazy now!

Honda already has a special break-in oil. I don't advocate deviating.

Well you are not crazy, but you are wasting your time, perfectly fine oil, and removing the special break in oil that Honda says should be left in until the scheduled oil change interval


Leave the FF in there, and wait until the oil change interval.

Go with your plan it sounds very reasonable.

You are crazy and it's not a good idea. Espec. running Valv. syn to 10% of an OLM; its a complete waste.

You're overthinking the situation. Let the oil and filter do it's job. Follow the recommended service interval and enjoy your van.

Just drain and fill. The oil flush makes no sense to me. I would understand it if you were dealing with a poorly maintained engine with heavy varnish, but that is not the situation you are in.

I followed Honda's recommendation and ran the factory fill to 5%. My Pilot does not need one drop of top-off oil.

Break-in == severe service IMHO. I don't go past 3750 first oil. Also it's a way to flush-out any casting sand or other bits that were inadvertently left during assembly.

Sorry, but the ages old 'break in' is just about dead. Follow the factory service recommendations and ignore the stealership advisor for virtually unlimited engine life these days.

I ran the FF in our Ody to 5k miles which was 30% on the OLM. I changed it out with the stuff in my sig, and 100 miles into the fresh oil change, I swear the engine opened up and was more powerful and peppy. I didn't reset the OLM right away so I could see what service intervals popped up, and it was A1. I'll probably rotate tires every 10k miles and ignore the OLM on that one, too.

It may have been all placebo effect, but it certainly feels like it has much more lower end grunt than it did before the change. I also dumped 3.5 quarts of ATF and refilled with DW-1 to get the break-in debris out of there too.

My Honda manual still recommends driving slow (
As for following recommendations.... which one? The US manual says use 5w-20, the EU one says 5w-30, or the Aussie/South American variants that say 5w-40 (above 0 F)? There is not one "correct" answer since oftentimes politics enter the equation & override the engineers.

Dont waste your time

Yes, you are crazy . You are way way too worried about nothing. Follow Honda's advise, and keep the factory fill in till 10% left. Let the break in fluids do their job.

And NO you have not left the FF in too long, as was suggested here. Keeping it in long will not do any damage to your engine, and will not shorten it's life. The filter well see to that, and keeping the break in fluid will insure your engine does last a long time.

On this site especially, you find a lot of posters that know nothing about oil, and they mostly have an oil fetish that demands strange and foolish ideas like draining FF early, and ignoring manufacterers recommendations. Most posters here are cyber loafers that spend hours chatting and socializing here because they don't have a real life.

And in fact, for me, watching this site is very entertaining, and for that reason alone. HAHAHAHA

Just two weeks ago a guy found a large chunk of plastic in his new engine.
He was lucky he drained the Factory fill early, rather than leave it there.

I think the old oil is fine until OLM gets to 0%. I don't know why you'd arbitrarily say 5%, 10%, or 15% left. That's a half-hearted weak statement. If you trust Honda, trust them all the way, it's good to 0% (and then some, cause that's the formula with the cheapest bulk oil).
I recall the Honda Manuals says something like "schedule a service appointment" at 15%; but don't take it to mean change at 15%, they just don't want you to rush an appointment at the last minute.

Anyway, unless you change because you want a change in viscosity, like the old was 5w-20 and you wanted 0w-20 i don't think you gain anything by changing early.


But the new oil is fine too, so you don't lose anything either.

For those harping on the special breakin oil and don't dump early. Yes, probably has more moly, but it's not like he dumped after 100miles. He's got 5k miles on it and over 100hours and 10 million+ Revolutions of the engine; whatever needs to be broken in, is broken in. The oil still has life in it, if you want to keep using it; but has long already fulfilled break-in duties.
