Oil flush after rebuild and new turbo

[murraymint]

i used engine flush on my car last week with my oil change, not a 1.8t tho, a crappy 2ltr 8v. the oil change was over due, so used engine flush on tickover for 20minutes as per instructions. and new oil and filter. the car now runs a lot smoother, pulls nicer and im getting better mpg.

Good work! Oil flushes are good and necessary it's just doing them properly and taking all factors into consideration

In all fairness you are probably the exception to the 'general' rule because your engine was recently rebuilt

Just wondering why you used gear oil and diesel?

[XMC1980]

Gear oil is thicker than engine oil but is diluted with diesel, Diesel is pretty inert at low pressure, you can throw a match into a pool of Diesel and nothing will happen (except the match will go out).

Perhaps additives are good but it costs £10 per litre, Diesel is cheaper

About 2 litres of gear oil and 5 litres of diesel and run it through. Obviously without starting it, it's just for running through, the gear oil will protect the valve stem seals etc

I have used it for cleaning and freeing rusted threads for years, much cheaper and better than proprietary products

I would still not recommend it on a 1.8t but your choice at the end of the day.

If you run the correct oil and change it every 5k, oil flush should not be needed.

I see.

I'd then be flushing out with fresh oil IMO, maybe I'm bias as I have 600 litres of oil sitting here.

If you have just rebuilt the full engine and the pathways are clear, I personally don't see the problem with using flush on a reg basis alongside the future servicing.

I will say, I would not dream putting flush in a high milage car that has never been flushed before.

My 2 cents.

I guess like someone pointed out earlier I have just had a full rebuild and new turbo, new oil sump was placed too with pick up pipe, I guess we all have our own reasons and opinions
