Went to top up my engine oil tonight and picked up bottle of t cut, realises when I started poring it that it was wrong colour . Help! How bad is it?My son is supposed to be doing his driving test in it tomorrow TIA

I know it’s late so no replies so far. Does anyone know if an oil change/flush will do the trick? (If I can get a garage to do it at such short notice in the morning) Gonna feel really s*** if my son can’t do his test. Anyone??

Has the engine been started since the T-cut was put in? if not can you do the oil and filter change before its moved

if you cant do it take to a garage by then it will be washed into the sump and most can be cleared with the oil change, but would do another change after a week or so, those engines are pretty bulletproof so should be ok

No I didn’t start it, realised straight away I was pouring wrong stuff in. Would have to take it to someone to do oil change. Do you think that would sort it? and dya think a local garage would do it at short notice in the morning. Thanks for reply

Depends on how busy they are, but as its a quick job I see no reason it couldn't be fitted in between jobs, and I didn't suggest flush as it can cause problems so best left as oil change

then repeat in a week, that should do it ok, good luck to your Son

Google if there are any mobile mechanics near you, a quick call to them before they go off to work may get you fitted in. If so can you get the correct oil and filter nearby (Euro Car Parts, a motor factors, Halfords etc) in preparation?
Toyota Corolla - Big mistake when topping up my oil HELP - Surreydriver

Beg, borrow or buy a vacuum oil pump. eg Sealey etc. If you are lucky the goop will be sitting on top of the oil. You will see whatever is vacuumed up (using the thin hose) as it enters the container. If its at the bottom vacuum the whole sump and refill.

Having used T CUT isn't it petroleum based so cannot think it would have done any harm. Expect it would quickly evaporate off. Still better to be safe than sorry!

I have owned a Pela vacuum extractor for a number of years and have used it on a BMW and a Nissan. Both had one thing in common and this would apply to any car, the device will not work with cold oil, even the 0w30 ued in the BMW, the Nissan used 5w30. Both needed a good run, probably about 8 miles to get the oil hot enough for the devise to work.

The Pela is not a cheap and nasty device, its as good as it gets. Once hot the oil is extracted within a couple of minutes.

T-Cut is certainly organic and will mix with the oil, so no use hoping it will sit on top. I would guess the abrasive is fairly mild, such as talc or chalk. Perhaps it will just put a shine on the cylinder walls .... :-)

well if its any consolation to the OP, its not the first time the wrong liquid has been poured into an engine and wont be the last, even experienced Mechanics have done it in the past

Toyota Corolla - Big mistake when topping up my oil HELP - gordonbennet

I know its too late now as the oil change is probably underway already.

If it was mine, and thankfully it's not been not started, i would have bought 5 or 10 litres some of the cheapest most rubbish engine oil, or any old unused engine any of my friends had lying around and, after draining what was already in, i would have poured that cheap oil straight in purely to wash the muck down, and then refilled with again some el cheapo correct grade, ran that for a couple of days, then drained again and then put the correct oil in and a new filter.

Don't be too upset, we've all managed to do the most idiotic things when distracted.

Thanks for all your replies, I’m a ‘she’ not a ‘he’ Can’t believe I picked the wrong bottle up, just wasn’t concentrating. I was more concerned that my son wouldn’t be able to take his driving test and it was too late to contact anyone. Called mechanic first thing this morning, he said he didn’t think it would do any harm and when I told him it was a corolla he said ‘ah they’ll run on owt’ ( his words) Had oil and filter change just in case, done in time for my lads test and... he passed! First time!

Thanks all. It’s in garage having an oil change

I'm wondering how you got it there, and hoping you didn't drive it.

I'd have flushed it with whatever I could get my hands on (within reason, and not including T-cut), kerosene, diesel fuel, used oil, cheap oil.

Lots of it

By flushing I mean pour it straight through, take the rocker cover off and pressure-spray it, take the sump off and mop it out.

Then I'd run it at idle for say 10 minutes possibly with flushing oil for 2-3 changes. If I couldn't get flushing oil I might use a mix of diesel fuel and 2-stroke oil

Then a couple of changes with cheap oil or used oil.

Then a final change with your oil of choice., .

This assumes you want to preserve the engine. If its disposable, scale it down appropriately.

There really isn't anything worse you could have done apart from maybe adding battery acid and leaving it there for a couple of months, and there is no way that a garage oil change is anything like an adequate response.

Suspect the mechanic is right in that old toyotas are fairly hard to wreck.

Thinking about it (chemically) I reckon if only a moderate amount of T-Cut was added, running the engine would probably do little harm. Once the contents of the sump had passed the filter, the 'abrasive' would be removed. The remainder is miscible with oil and probably volatile enough to be burnt off anyway. Perhaps the filter would need replacing if it was rather bunged up?

After all, T-Cut is not intended to damage paintwork, is it?

Not good customer relations to make with the bad vibes when there's nothing practical to be done.

You got a lot of confidence in the average oil filter. If the stuff is all coa*** enough to get stopped by it (greater than say, 50 microns) then OK, but you point out that its quite fine.

In this context, that isn't a good thing.

If it wasn't abrasive, it wouldn't work.

If it's co@rse enough to damage the engine it will be filtered out; if not, it will smooth the mating surfaces. The abrasive in T-Cut is not harsh, paint is a relatively soft material compared to cylinder liners and the micro-swarf off them which the filter is intended to catch. I don't think some T-Cut is a serious threat to an engine, especially if it's removed smartly.

Oiil filtration is perfect, and everything is for the best in the best of all possible worlds.

This goes way beyond T-Cut .

Not sure what point you are making, Ed. Mating surfaces are meant to be 'smooth'. What damage are you expecting T-Cut to cause? (you haven't said).

But there is more than just hydrocarbons and ammonia in T-Cut - definitely some buff-coloured solids. It sets hard after years of neglect (unless the formulation has changed ...

Toyota Corolla - Big mistake when topping up my oil HELP - edlithgow

Assuming it is a fine abrasive, I'd expect it to greatly increase wear. The mating surfaces would be smoothed (they were probably already smooth), then they'd be removed. AFAIK polishing metal always removes material.

If the engine was run with this stuff in it (say, to go to a garage for an oil change) then I'd expect the abrasive to be embedded in bearing surfaces and continue to have an abrasive effect after that, and subsequent oil changes.

This "ïf its big enough to cause wear, the oil filter will get it" jive is a comforting myth. If you poke around a bit you'll find plenty of research to the contrary, and on my current car I have anecdotal evidence in the form of fine ferrous metal settling out of the oil on standing.

I don't think you are making allowance for relative hardness, Ed. T-Cut is intended to remove 'dead' paint, a very soft material. I'm guessing the 'abrasive' component of T-Cut (the data sheet doesn't reveal) may be talc (Mohs hardness 1) or possibly gypsum (Mohs 2) while iron or steel are about Mohs 4.5. So during the short spell while the gubbins is in the engine, the metal will grind down the T-Cut, not the other way round. I wouldn't lose much sleep over it, anyway - just get new oil and filter soon.

Toyota Corolla - Big mistake when topping up my oil HELP - edlithgow

Could be, hadn't considered that.

OTOH bearing metal is about 1 on the Mohs scale.

Aluminium starts about 1 too, though I'd guess the relevant alloys are harder

Yeh, well then, we disagree. No big surprise there.

This is a fine industrial abrasive.

in an engine.

Presumably a fair-sized glug of it

You think driving it to a garage and getting them to do an oil change is an adaquate response to that situation?

You think anything more is excessive?

You think its for some reason OK to use flushing oil in a coked-up engine (in which situation its likely to do nothing at all) but not OK to use it to flush out loose abrasive (which it should do OK, why not?)

OK, them, go ahead and think those things, but since I can't think of any reasons for thinking those things, and quite a few reasons not to, in the absence of a rationale I'm going to assume you're wrong.

That said, most cars get scrapped with functional engines and I daresay that's what'll happen to this one too.

Safety sheets are an uncertain guide at best.

I doubt they'd have to put abrasive in the description if there is any in it, since its likely to be chemically inert.

Toyota Corolla - Big mistake when topping up my oil HELP - sammy1

If T-CUT was that abrasive it would take car paint down to bare metal with just a few rubs. My experience of using the stuff is it is more the petroleum base that removes minor marks and scratches. I cannot see it having any affect on the internal metal of an engine, but wise to get the oil and filter changed. Not a fan of the vacuum method of changing oil, dread to think of what is left in the sump if done cold. You leave your car at the garage at 9.00am and they get around to it at 4.00pm bound to be cold.

This saga could be the basis of the next Specsavers AD!

Well, if that's your definition of "äbrasive" then of course you would be correct, but that isn't the definition of ""abrasive""

What others do is up to them, If an engine needed a strip down years ago it got one, unless it wasn't worth the time and expense, so I'm not going to change my mind now

Last line was fair enough, I thought. I probably was in an argumentative mood. Usually am.

I enjoy a good argument, especially if I think I'm winning.

This one, not so sure.

I'm no big fan of flushing oil. Only used it once, when I was much younger and wanted to "do the right thing"with a dirty old engine. Comma stuff. Wasn't especially impressed.

Just thought this was a suitable application. If not, as I said, I might use a diesel fuel/2-stroke mix, or maybe just cheap oil.

I wouldn't normally use diesel/2-stroke in an engine, but that was based on my perception that this was an extreme emergency, because I was assuming that T-Cut was an abrasive.

If it isn't, then I'm wrong. I dunno how you'd find out. The company probably isn't going to tell you.

Toyota Corolla - Big mistake when topping up my oil HELP - FP

Surely T-Cut contains abrasive. Otherwise, how could it remove scratches?

It's clearly not abrasive like sandpaper or wet-or-dry, but there are grades of abrasivesness and I assume T-Cut is at the lower end. Even clay bars are abrasive, as I understand it, but very mildly so.

Even toothpaste contains abrasive.

Edited by FP on 04/07/2019 at 13:47

Toyota Corolla - Big mistake when topping up my oil HELP - skidpan

Even clay bars are abrasive, as I understand it, but very mildly so.

I thought clay bars picked up contaminants from the surface without needing to remove or damage any of the paint (if used correctly). The use of lubricant (soapy liquid or specific one) would appear to confirm that the clay bar does not actually touch the surface.

Use T Cut on a red car and the cloth will be red afterwards confirming that some paint has been removed and surely that removal will be down to the mild abrasive action. Use a clay bar on a red car and all you will see is the bar changing colour as it removes surface contaminants, it usually turns darker as it removes tree sap especially. Use the same type of bar on a white car and it goes exactly the same colour.

Toyota Corolla - Big mistake when topping up my oil HELP - FP

You may be right, Skidpan, but remember most car paint nowadays has a clear coat of lacquer on top of whatever colour the eye sees.

That could be why you don't see any colour after using a clay bar. You would need to compare with T-Cut on the same vehicle.

Toyota Corolla - Big mistake when topping up my oil HELP - John F

I guess she poured in no more than 50mls from a standard small bottle of T-cut. Imagine that spread through around four litres of oil, passing through the filter before reaching important bits. I doubt if there'd be any significant wear even if she drove fifty - or even 500 - miles before the next oil and filter change. You'd have to rub an oily bearing surface or piston ring really, really hard for a long time with neat T-cut to remove a significant amount of metal. Incidentally, T-cut is basically overpriced Brasso which is just as good for removing paint scratches.

Toyota Corolla - Big mistake when topping up my oil HELP - focussed

In the big diesel industrial generator industry there can be a problem with standby gennys started up weekly or whatever to run a regular test, if this is done without loading the generator with an electrical load bank the engine can glaze the cylinder bores with the zinc additives from the oil, which gives bad ring sealing and increased oil consumption.

There was a solution from a particular diesel engine manufacturer called "Cat Powder" (guess which one?)

The powder was mostly pumice powder apparently. What you do is-

Engine on 50% load - air filter removed to get access to turbo inlet, a spoonfull of the magic powder trickled in the turbo inlet and gets blown into the cylinders with the inlet air, repeated a couple of times. Abrasive enough to remove the glaze and reseat the ring packs.

And then change the oil!

So I wouldn't worry too much about a drop of T-cut!
