Title: Engine oil flush
Post by Paulus on Feb 8^th, 2006, 7:33pm

I have read lots of advice from the forum on doing an engine oil flush. However, I have been given some advice from someone that claims to know about these things. He suggested that the best way to do an oil flush is to replace the oil with the same amount of Diesel, let it run at standstill for 10-15 mins, then drain and put in fresh oil/filter.

What's your thoughts?

Paul.

Not heard that one before!

I wouldn't risk it personally.

No Way!
Any Motoring Shop that have Engine Oil Flush will do, you could ask the staff while you're there as they would be happy to help.

A good idea is to buy 5lts. of £3.99 cheapo oil from Tesco's, fill her up, run on idle till hot, drain it out and put in the good stuff with a new filter.

Diesel idea sounds real dodgy though :-/

With using Engine Oil Flush would remove the sludge and insoluble deposits to help free up the Hydraulic Valve Lifters and quiet down the noise too.
Using cheap Engine Oil won't help with Oilways as not ensuring to help Oil flow to critical moving parts and the new Oil & Filter will dirty quicker.
An 4.55L Flushing Oil low viscosity Monograde Oil SAE 20 which is an save bet to use and an cheap Oil Filter to go with it, after that new Engine Oil and Oil Filter - Ford's or your choice, until next time service. ;)

Not advocating the diesel fix but typically diesel has detergency agents built in and maybe the original idea is about dissolving deposits. Would hate to be the one to turn the key, think the viscosity will be much to light. If you really think it needs it the engine flush would be a good compromise.

Other thing is that Wynns do an additive for freeing up hydraulic lifters/valves for around a fiver and that might be a good idea before an oil change if you think that you have a problem, I used some with my 2.0 litre at 130,000 and it seemed like a good move, followed by oil and a filter quietened things down nicely.

So it's not a good idea then?

I can take a hint. ;D

My 12v has got 194000 miles on it and the engine sounds a bit tappy. Other than that, it's a fantastic car. The only car that I am considering changing it for is a Cosworth.

Thanks for the advice guys.

most 'engine flush' is based on a light viscosity oil, this breaks down the sludge etc. sounds like there is good basis for the theory as diesel is a thin oil, however, i personally wouldnt advise switching all the engine oil with diesel, maybe a quarter. also, you wouldnt save any money considering the amount of oil in the engine, 6ltr in my 2.5 td, easier and cheaper to add a 5 quid bottle of engine flush.

Just to add to all the above, if you read the contents of these "engine flush" treatments, what does it say on them ???, "This product contains Diesel" !!!

Please don't take it that I'm advocating the replacing oil with diesel, as I'm not, and I certainly wouldn't want to be the one to turn the key either.

I just thought it may be a point of interest.

Now you've lost me... I thought you were talking of a "manual" engine flush.

By manual I mean that you hook up a machine that pumps around a fluid instead of oil through the engine, solving residue and flushing it out.

The procedure I am familiar with is called Bilstein Engine Flush.

They put two connections on the engine: one at the oil-filter channel; the other instead of the oil-sump plug.

Through the oil-filter channel they pump a fluid they call R-2000 (probably a light-viscosity solvent) which they've heated up. It flows through the engine and is pumped out through the sump-plug-hole.

Of course, they collect all the sludge and residue in some type of filter, and lets the fluid circle through the engine for some time.

That sounds like a real treatment to me instead och stuffing a lot of chemicals in the engine and running it idle.

I used the Forte products engine oil flush myself. Had an issue where we had to have a replacement engine fitted (Cosworth), so I ran this engine on 5W-30 oil for 500 miles then flushed with the Forte product.

Added new 5W-30 oil and also put in some Forte 'Top End Conditioner' to help with any hyrdraulic valve noise.

Runs lovely.

Forte is not available for general retail.

However, we use the stuff at work ;)

I've used Forte products before with good results too. They are "trade only", but there's quite a few items available regularly on eBay.
