Engine oil flush recommendation. #5135874 06/16/19 04:24 PM

Hi,

I have a 2009 Honda Accord LX with 28,000 miles.
When checking the oil 2,000 miles after an oil change: on the dipstick the level is fine, but the lower half of the oil on the dipstick is dirty while the top half is clean.
Would like to do an engine flush that is effective, but also gentle / safe as I don't want to cause engine wear on such
a low mileage engine.

Does anyone have a good recommendation on an engine flush that is both effective and gentle (safe) for the engine?

What about Amsoil engine flush? I think Amsoil mentions its safe enough to use it with every oil change?

Thanks,
Bill

What kind of oil do use? Some synthetic oils do a good job of cleaning by themself.

I will be switching to Penzoil Ultra Platinum 5W-20 with my next oil change. Its the 2.4 Liter 4 cylinder engine.

At that low of a mileage, i'd use a good synthetic. Pennzoil or even Mobil 1 high mileage. Mobil 1 claims there high mileage to be a cleaning oil. I would use no flush, the only other thing to consider is Kreen with a 5w30 or 5w40 oil.

Does this vehicle sit unused for long periods of time? Seems like it must, given only 28k in ten years. Personally I would not worry about it. Just shorten your change interval to one year or 3k and go on enjoying life.

We bought it a year ago with only 6,000 miles on it from the original owner who was an old man who recently got too old to drive it.
So from 2009 to 2018, it was sitting a lot with very low usage.

Question: If I switch to Penzoil Ultra Platinum synthetic and change oil every 4,000 miles, how long would it take to clean out the engine?

We will be driving the car 20,000 miles a year from now on.

Well, if you use synthetic oil it should clean it.

I would rather use an American-owned oil brand, but it's your choice.

ok, but back to original question, what is the safest (no engine wear during engine flush) engine flush?

Asked and answered. What everyone is trying to tell you is that you are obsessing over nothing. Change the oil to any quality synthetic and drive it. If it makes you feel better, do a couple short intervals but you will just be wasting money.

That should do a good job of cleaning it out.... but I'd change it out as soon as it gets dirty.

+1. Use the manufactures service recommendation for severe service and sleep well. Skip the flush altogether because it isn't needed if you use a quality oil. Ed

+1 With only 28K miles a good quality synthetic oil like PU should slowly clean it up.

So what did you do over the course of those last 22k miles? Seems to me that you've had plenty of time to flush it out.

Been doing conventional oil changes every 5k miles at Walmart (They used Quaker state conventional on my car). Recently realized it was dirty on bottom half of dipstick. Previously to noticing it, never really paid attention, and just had the oil changed every 5k miles.

"dirty on bottom half of dipstick".....what does that mean? Take the oil and touch it on some paper towels. Is it really that dirty? All cars show some dirt or darkened color after a thousand or so. You're over-thinking this.
