I have a 04 reg 2.0L TDCI with 50K on the clock. My Ford garage is highly recommending an engine flush as part of my next service -I did succumb 2 years ago. I know diesel oil gets very black, so is this worthwhile or is it just a money making ruse?



Great site by the way.

Cheers

Mark,

I don't think it does any harm if it is done regularly as the engine doesn't get enough chance to build up too much carbon etc inside.

This is for both Petrol and Diesel engines......

A local independant garage and also my local Ford RS specialist said the best thing to do is:

> Run the engine till its warm
> Drain the old oil out. (use common senseas it will be HOT..!)
> Refill with cheap oil and run the engine for a little while.
> Drain the cheap oil out (because it will be hot, it will drain loads of the thick sludgy cr4ppy oil out as well)
> Refill with the 'good' stuff and you're done.

The problem with a lot of engine flushes is that they clean and remove everything (old oil and carbon build up)
Someolder/ higer mileage engines can benefit from abit of cardon build up becauseit can help create a better seal for the pistons. Remove that cardon seal and the engine can become noisier.

I hope that helps.

Never really given much thought to this till now. Trip to Asda then for some cheap cheap oil then.
Another job to add to the list
Oil flush and change + filter (of course!)
New front discs and pads
Brake fulid change

Silicone spray the door, bonnet and tail gateseals.
