Engine flushes...

[Conor]

While this is unmerc related .. you are my automotive guardians ..

Anyway, just about to put the Range Rover on the road and going to change the oil before hand, as I'm not sure it's been done in a while (last record is 24k miles ago).

So.. while I don't plan on using a flushing product as I believe they can open a can of worms.. I was thinking of perhaps running some cheap(er) oil through it for a few hundred miles just to get the old stuff cleaned out and prevent it mixing in with the new stuff..i'm not sure it would make a massive different, just the idea of it seems a bit comforting.

What do people think? I have found some cheap oil ("North Sea Lubricants") which is the same weight and has some good specs, sold by Euro Car Parts in Ireland. I was thinking to use that. What do people think?

Don’t see why not..

I did the same on my V6 w203 when I bought it, also 24k since last service.

I drove it one mile down the road from where I bought it, got the local garage to put some random semi synthetic 10w40 in. I drove it gently 100 miles home, and then did another oil and filter change with Mobil 1.

The filthy colour of the oil after 100 miles was in some ways reassuring that it had done the job I hoped.

You can get pretty decent cheap sythetic oil as well that will be pretty close to the your required spec, and for a single, gentle decent run I can't imagine this is going to cause any damage e.g. £20 for 5 litres Euro Car Parts sort of thing.

Best bet , it's a gentle clean , I always do two short oil changes when a car is new to me .

Flushes can lossen bits that can block the finer oil galleries .

With flushes there's detergent based and solvent based with the higher posibility of any issue with the solvent based .

Thanks guys, yes it should be reassuring alright.

I will be avoiding the flushing products.

For the money you'll save using a "Cheaper" oil for a few thousand miles and risk mixing some of that with the genuine article, if I had any genuine concerns I would use the proper stuff for both changes and change the filter both times as well.

I am with tony on this.

Flushing comes in a few guises.

The old skool flushing oil, like pee, remove all old oil and add flushing oil - I would avoud.

Or a can of something like liquid moly pro flushing additive to add to the oil and get warm and drain.

I would do as Tony, using the liquid moly initially. Once you let it drain go for a cup of tea or see to other jobs to make sure every last drop is out.

When I bought my W203 it had a service on sale, but there had been a long time since the previous oil change due to low milage. I ran it for about 500 miles, put in a cheap (but in spec) oil & a new filter, did another 500 and then good oil & another new filter. Then changed every 5000 miles since. I always keep an eye out for sales, to ensure I have filters & oil in stock ready for the next change.

You don't have to avoid them, but as mentioned in another post stick to a detergent based one as these use the same cleaning detergents found in conventional engine oil, just more of them and one of these will be fine.

In my opinion though, there is rarely a real need for one today with modern engines, lubricants and fuel.

Cheers,

Guy

Using an oil for flushing is also what I do. However the oil needs to be of the correct specification.

Additionally you don’t have to buy the cheapest no name stuff just because it will be used for a short period. There are usually many reasonable choices at reasonable prices.

About 15 years ago I once tried Wynns engine flush on my 328i at the time simply as I thought it designed to clean and surely that’s better right. Wrong, had niggles for several months following that!

Well this is up to you . And there will be members that say, use it, or dont ..i am a dont use it one Because if you dislodge any sediment from inside the engine,. might even be gasket sealant it can move down the oil ways on its way down to the sump , and it might just block one of them up . In all types of engine oil there is a detergent to keep them clean . Regular oil and filter changes , are better plan . Just an old gits two penny worth ..

I couldn't agree more with this sentiment in the thread.. for the perceived gain of flushing the engine (Is it even proven to be good!!?), it's simply not worth the risk in my book.

I think a quick succession double oil change should be good enough for me.

That's what I would be going for as well....use correct spec long life oils, and short mileage changes. I've just bought 20 ltrs Mannol LL engine which is in the MB BEVO approval list. Cost €115 ex. Amazon de.

Yes agree with the regular oil change regime <5k miles don’t forget the extended oil service was only invented to please the fleet buyers.
As regards the OPs situation I‘d do a quick couple of oil changes at 1k interval using the correct spec oil

Back in 2011, I bought a new Skoda Octavia, and one of the main selling points touted by the salesman was the long service life, 30'000 klms between oil changes. Not a believer, I brought it back to the dealership at 10'000, and he said "Oh,you got the letter from Skoda about the reduced service klms I see,but its 15'000 klms,not 10'000. Well I said, I didn't get any letter yet, but 10'000 klms is my service schedule, and I'm sticking to it.

Taking things to a bit of an extreme although it is a very valuable car I remember some years ago reading a review of a privately owned 300SL Gullwing which I found very interesting, the owner changed the oil every time the car was used, obviously the car wasn’t used that often and was no doubt owned as an investment/enjoyment proposition but says it all really. My BMW has covered 12.5k miles and will get it’s fourth oil change at the next service. I think anyone running a DI petrol engine should definitely change the oil <5k miles they do suffer a lot of oil contamination from soot washing past the rings

 

[mioba]

sounds a bit like @Wighty the person with the gullwing.
