engine flush - yes or no?

[jonny_g]

just wanting to see what the opinion is on using engine flush when changing the engine oil?

personally, i have always used it on my car. Has had about 4 oil changes since i owned it and has done near 30k in that time without any problems so far as im aware.

so i just want to see what evryone else out there is doing.

I don't think it is neccesary as long the engine gets fresh oil regularly...I'm afraid the engine flush might damage seals and gaskets....

Ive been told its a bad idea as it could dislodge deposits that might not necessarily drain out that then float round the engine and potentially cause damage.

ive always just took the car a good long blast to get oil temperature and then drain it

^ imo thats a better idea, best drained red hot

Is thats because its thinner?

 

[Jay Payne]

yep

 

[Daniel]

Ah nice. Thats what I do so I was just making sure I was doing it for the right reason!

Exactly what I do! Gets pretty much every last drop of oil out that way.

yup i just drop the oil every 6k, and use decent oil,thats plenty good enough

flush can do a good job of freeing up a sticky lifter or the like. If the engine is really clogged up then yes it can loosen things which weren't causing a problem and make them an issue.

Is it true that diesel mixed with a bit of old oil makes a good engine flusher?

 

[Russ_16v]

i would say in theory yes, but i wouldnt!

 

[caister]

Nah i wouldn't either but im sure ive read of someone doing it on here somewhere! Fred maybe but im not sure.

I was told by Guy from opieoils never to flush the engine . Just change the oil and filter , job done .

 

[Alastair.]

i wouldnt use it on diesels, ive seen it used on a nissan primera diesel and it fuked it rite up, not so bad on petrols but i would only use it on old petrol engines.

 

[jonny_g]

interesting points, may decide against it in the future

hey guys,... stupidly i said yes to get my engine oil flushed this morning... They made it sound like a great idea at the time. Have since read posts like these about not flushing.. i guess its too late now as the flush has been through, shall i just run with the new oil or should i drain it and start again to save damage?
