engine flush at oil change recommended?

[bigjacques1]

Is it recommended to use a engind flush product on a 2006 c class when doing a oil change,and if so what product will be recommended

 

[Terry_]

I would recommend a forte product

The theory is that it is a good idea to regularly flush the engine during oil changes, to avoid build-up of sludge and deposits.

However if you flush a high-mileage engine that has never been flushed before there is a small risk that the flush will dislodge some sludge which will then go on to block one of the small oil passages and will kill the engine.

Said that I have flushed high-mileage engines in the past and had no issues, though I obviously can't say if this is because the 'theory' is rubbish or simply because I was lucky....

Hope this helps.

Thanks markjay.I have 85000 miles on the car and could you recommend a engine flush to use ?

Statistics say you will not own the car for more than 3 years so do sod all or fill it with it with olive oil

i personally wouldnt use a engine flush, why do you think it needs a engine flush? Just give it a oil and filter change then again at 1k later if you think it needs it. I always give my cars 3k between oil and filter changes.

Personally I think it's marketing bull. The key word being flush , you flush your toilet to make it clean, your flush your body through to make you feel better etc etc. Would like to see facts that this is 100% beneficial to engines.

It does work, and it removes gunk and other stuff.

But I think you will find it is one of those things where opinions are divided, due to the potential (and theoretical?) risk.

From memory I think I used Wynn's Engine Flush, it was a long time ago... but Forte and Millers seem to be the recommended brands these days.

If you have sludge in your sump something is wrong.

Flush makes the oil more liquid and therefore drains better amongst other properties.

s350 cdi blutec 2011 oil flush

Hi sorry to hiJack this thread , but I've just bought a s350 cdi blutec with 135000mls.

It's due a service been 15000mls, I usually change oil on my 642 every 10000mls. I was thinking of flushing the engine. What would be your thoughts , what oil would be recommended .

Sifting through the receipts I've found that the guy I bought it from uses you guys at prestige car services .

I bought the car from fareham.

What leads you to believe that your engine is in need of a flush?

Hi, I've just purchased the car. My friend has a s350 cdi and his engine has sludged up. So a bit frightened . What oil should I use. I've used Mobil 1 esp on all my cars before. I thought I'd use flush just to b on the safe side .
