Engine Flush

[flipperthebushkangaroo 2]

sorry if i am just repeating a previous thread,

i have searched but without success,

i was in halfrauds today getting some oil when i spotted some engine oil flush stuff, its supposed to clean out the internal gubbins of you engine, not sure about this while my engine oil is mingin won't this damage seals and weak points in the engine?

 

Any advice is as always very welcome

Cheers

I do it regular and think that it is a good idea. The engine always feels better after a flush, a filter, and some fresh oil. Maybe it's phsycological but if it feels good then do it, it can't do any harm.

I've done it with a parraffin/diesel mix in the past. Not recomended but the oil was clean for a while afterwards

have done this on all of my cars and no noticeable gains...

I read in a tunning book one time that they tested the stuff and found that it only made a slight difference on a higher miler engine that had been poorly serviced. I use the wurth engine flush on my cars. Let them run for about 10 mins then drain them. It thins the oil down a little and makes it drain faster. Probably just cuts down the time you have to wait on it fully draining before you put the bung back in. Couldn't be too bad on an engine.

Been told that on an old engine it can cause leaks to get worse as it cleans out rubbish that was otherwise helping the rather worn old seals.

i have to agree, i have done them on both 205's i had and made them leak afterwards, i would never do it again.

Yeah i've also heard as above hat on a higher mileage engine it can do more harm than good. Saying that I've always used it on my previous cars. If a god synthetic oil is used and changed regularly (6000 miles) it shouldn't really require flushing (In theory anyway)

Yup I would agree about flushing oils helping to cause leaks & I remember reading somewhere that flushing oils were really to be avoided with hydraulic tappets as the flushing oil gets into the tappet buckets but not so good at getting back out - Not so easy to drain these!

 

Any time I've come across a car with really dirty engine oil then I've drained it, filled it with any old £4 for 5Ltrs supermarket cheapy oil then driven a gentle 20/30 miles, drained it and then refilled it with the good stuff.

 

This has really kept the new engine oil clean for ages & works for me......
