Engine flush products?

[JB21]

Do they actually work or should I just use a decent synthetic oil and do a few flushes with that?

Pick my replacement engine up this week and it looks like it's been ran on non synthetic oil hence the heavy varnishing, it also has slight sludging but nothing to bad given it's on 150k miles.

Don't flush....ever....🧐

Aye, exactly why I asked as I've read it can do more harm than good.

I wouldn’t flush it.

Just get some halfrauds cheap fully synthetic oil in it and run it for 2k miles and then drop it again for new oil and filter again.

I’m sure my dad used to flush some diesel through his. Nutter.

As above, would not flush it out. Bang some correct spec cheap oil in, do 500 mile or so then drop it and fill up with the good stuff.

Add an oil detergent dont use a flush. Run it red hot on a dual carriageway run and then drop it while it still hot/warm but watch your hands😂

Alot of the flush products have came a long way since years ago and there was the fear of fkuah getting into bearings and then preventing oil from getting in

I used to use forte treatments myself, moved ontl fueltone now and so has alot of other mechanics that I know who used to use forte

Why do all these additive sites read like snakeoil salesmen?
Nothing concrete, nothing checkable.....

 

[Mertin]

Im sure if they were as harmful or useless as everyone makes them out to be then nobody would use them and companies would collapse as quick as an unflushed engine

Probably wasted £10 a year on worse things

It’s like taking a multi-vitamin: you do it every day believing it to improve your general health - but you’ll never know if NOT taking it would have left you less healthy!!!

Last flush stuff we did on my mates old car just smelt like Paraffin.
To be fair it worked tho.

Just going to use a 5w 30 to flush for 1k miles, then go to a 5w 50 for track days. Not going back to 15w 50 as I reckon it was to thick for cold starts.

 

[R3k1355]

So why not 10w50?

 

[JB21]

So why not 10w50?

Its not as reliable in winter months on start up being thicker. No problem in the hotter months but 5w 50 is cheaper so win, win all year around.

 

[JamesBryan]

No need for 10 and 15w50 in our climate.

needs a tub of Forte banging in and running for a bit. Old man used to swear by it when he was running his garage.
