I usually replace my oil in my VRS every 6000 miles or 8 months (which ever is sooner).

Every time I do though I always seem to get a small amount of old oil left because once the new oil is in (with new filter each time) the oil is never nice & clever & always very black. My old Seat Ibiza use to have lovely clean oil after its oil change.

Now, I do tend to drain the oil with the car still jacked up on one side - does the oil drain much better if completely flat or on a slight slope etc & because of this is it leaving old oil in the sump thus my black oil problem.

Also, as the topic denotes, can I use one of those engine flush cleaners to get rid of any built up gung (if any)

I've been told that I shouldnt use them in PD130 engines. Is this true?

I also use fuel cleaners now & again - are these ok?

btw - the engine has a common factory added remap.

NO, you will fook the engine

NO, you will fook the engine

fair enough

It's quite normal for diesel oil to look black almost immediately, however, when you change the oil do you empty the filter holder? It is open at the bottom (as you'd expect) but has oil traps at the sides and holds a surprising amount of oil once the filter itself has been removed. HTH

Some oil does remain at the bottom of the filter holder - but its not a lot, I would say about a few table spoons. I do try to mop it away though. Its only because the holder is slightly angled so the oil gets trapped along the bottom edge instead of escaping down the center.

So, there’s no reason to worry that the new oil is black almost immediately. That’s normal is it?

for a diesel yh, they get very messy (im agreeing with above btw forgot 2 quote)

Why do you think this?

No matter how you drain the oil, there will always be engine oil in places where it won't drain away. If you look at pictures of engines with their cam covers off, you'll see loadsa oil clung to the tappets and cams and stuff, so it's not suprizing fresh oil goes black again after a few days..

Don't worry too much about the colour of the oil after a few days, it's not the colour that counts.

6000 mile changes are so frequent, your engine will be spotless

Oil in a diesel will go black after a few miles. Normal.

Why do you think this?

i was answering the OPs original question about engine flush, something that should never be used on any PD engine

It's your first diesel,isn't it?

As soon as the oil leaves the bottle and enters the engine,it's black.Diesel engines produce soot.Diesel engine oil contains detergent to keep the soot in suspension in the oil rather than allowing it to settle in the nooks and crannies of the engine's internals.

Black oil is completely normal.

Relax.

If your concerned about flushing the engine, the safest way of doing an engine flush is with oil. use a new oil filter cheap mineral or semi syth oil (not easy for a PD engine) and run it for 100-150 miles, then repalce the oil and filter with your prefered choice.

As said tho, the way a diesel engine works means that the oil will change colour quickley.

just to make sure, the only oil that should be put into a PD engine is the correct spec oil, not cheapo cr@p stuff from Tescos or whatever

yes, what are the reasons for not using a flush on a PD engine?

You need a good "shear" quality oil in a PD engine

When i had my 1st Fabia vRS, i used the main dealer for it's 1st service and they put an engine flush through it and charged me accordingly. I argued that this was totally un-necessary but they said it was part of their service routine. Car had done less than 6000 miles

Either they didn't know what they were doing, which is entirely possible, or it is/was part of their servicing on PD engines. I have never used main dealers before or since, and never used an engine flush and done some galactic mileages in a few of my Skoda's, albeit not with PD engines, and never had a problem.

A friends Superb taxi has over 200,000 miles, PD130, and never had an engine flush in all that time. Think that says it all.

A Skoda main dealer that treats peoples cars with such gross negligence should be named and shamed.

As a matter of interest, why would a flush be bad for a PD engine. I argued with the dealer that it wasn't necessary because I dont think its ever necessary with modern oils/engines, but I didn't think it would do any harm.

It may result in bore wash due to over cleaning. You may also damage the portion of the camshaft that operates the PD injector rockers.

yes, what are the reasons for not using a flush on a PD engine?

the camshaft not only opens the valves, it also pumps the injectors up to about 2000 bar, so as you would imagine the camshaft lobes are under a tremendous amount of pressure, so require an oil that will protect them from that wear, an engine flush will not give this protection, so could cause a huge amount of wear in the short period of time it is in the engine, HTH

My Skoda Dealer receipts for servicing clearly states £9.99 for flushing oil.--- I do my own oil changes at 12 months approx 6, 000 miles (since retiring), and don't use any flushing oil.---- Oil always went black immediately after service, whether Skoda Dealer or I did it.--- Other members confirm the same happens to their cars, and seems quite the norm.--- I would like to be financially stable to buy 10 gallons of engine oil with 10 oil filters to see if I could get the oil to remain clean, by repeatedly changing the oil, to prove a point.
