Safe to drive with Engine Flush?

Hi, I decided to do my own oil change on my V9X, not knowing you need a special sump plug removal key.
So I got ready to do it and poured some engine flush in the engines as per instructions.
Got under the car and realised I couldnt go ahead.
Q: will the engine flush damage the engine if not drained?
Q: can I still drive it with engine flush still inside until I get the correct tool?

Cheers

My understanding is that engine oil flush additives not only break up sludge but start breaking down the oil. It's not recommended to run the engine for more than 5-10 minutes after adding it, and certainly not stress the motor too much.

The drain plug is supposed to be an 8mm square drive. You are supposed to replace the washer each time, but any square tool 8mmx8mm should work, so it ought to be possible to fabricate that yourself if you have access to a modest workshop.

For all I know, Supercheap might even sell something like that ... I can't find it on their website but I'm probably not asking the search engine the right things.

Thanks old Tony i'll give it ago

Hi FiveFiveZero































































The quickest way to get a sump plug tool is to grind the male end of a 3/8" socket extension by about 1mm on each side. You will probably find that the tension let's go with a bit of a crack.
I have done mine a few times now and it works fine. Tool is a permanent resident of the glovebox.

If you can't find a tool for the job, I bought a 1/2" to 3/8" adaptor and ground 2 adjacent sides down on the 3/8 side until it fitted the sump plug. Similar to you I was already to change the oil and then had to go and find something to fit the plug. Only the French would make a plug that needs a special tool.

Thanks. Do you know what size thread the sump plug is?
I think I might upgrade it to a standard sump plug nut.

Hi FiveFiveZero,
I don't know the size off the top of my head.
I was going to do an oil change when I get back from Bali at the weekend but I smashed a couple of bones in my lower leg than needed surgery (no scooter or alcohol involved) so methinks that is now on the backburner.
I do have one suggestion though. If you have any concerns about the flush being a degraded oil in the vitals of the system trying to give lubrication to the bearings, gudgeons, valve train etc while the engine starts and runs up to pressure, consider pumping new oil through a squeeze bulb via the oil filter gallery. I did it when I rebuilt the motor and was easy to do. I had oil pressure before the engine fired and did not even get the customary valve train rattle of a normal oil change.

I bought this set a while ago when I had my CX5

I'll level with you.. I'm getting a lot lazier these days and a while back I bought one of those 12v oil extraction pumps from ebay. I don't even bother getting under the car anymore or undoing the sump plug. For the sake of leaving 150ml of old oil in the Sump, the pump is absolutely worth it.

It appears that ive now overfilled with oil. Its slightly over the max notch on the dipstick.

How big a deal is this or do i need to drain some oil.(thats a pain)??

Slightly over the full mark is no issue, better to be slightly over than under!

Depending on the K's and engine condition you'll more than likely burn that excess oil off in general driving
