engine additives/flushes

[Tazzy]

are these any good? wynns and redex, do they help or are the a waste of money?

cheerz ta very mooch!

[craig green]

waste of money.

Dont do it.

Pour a pint of new oil through the engine & out the sump when you drain it next time you do a lube service. This will carry out more sludge.

The flushes often remove the film of oil that is keeping high mileage engines running smooth.

I have a can of this sat on my shelf but always been weary of flushing products for the reasons craig mentioned.

[Kev Turbo]

ditto whaqt craig mentioned wouldnt use them just pour fresh oil through the engine until it comes out clean, get some cheap stuff (correct grade) and just put it in fire it up and then drop it again this will flush out anything

[craig green]

If an engines done 120k miles & never been flushed, why start now & waste good money?

I have heard stories of flushes being used & the engine grinds to a halt the following week etc. Because it washed out vital oil deposits that occupied the space generated by years of wear. Maybe use them from the off on a brand new motor but its just wastage tbh.
As said I drain the sump, leave it 10mins & pour a pint or so of fresh oil through it. You will see the fresh oil come out a bit mucky, thats good enough for me.

Money far better spent on a new rotor arm or brake pads. Things people are put off by because pouring in a can of flush is easier....

Alex's car loved the entire bottle of redex I put in there lol

I used to run a few tanks of optimax through my car to clean it out, which worked well. It really doesn't seem to like VPower though :confused:

[craig green]

you thinking fuel additives Jack?

Were on about engine flushes..... pour in through the oil cap.

[Jack]

Good point.. lol

All the advice I've always been given is to run a few litres of oil through the engine when changing oil.

Wouldn't recommend putting petrol or redex in where the oil goes though lol lol

[womble sri]

what about the injector cleaner

[Adam]

Only good way to clean injectors is ultrasonically.

All's i do for engine flush is drain the oil when hot, keep the same filter on.
Fill engine with some 20/50 ?3 stuff, run that for 20miles.


Empty that when hot, fit new filter, fill with decent oil(10/40w semi synth)

[Tazzy]

ok, cheerz, wont bother with flushes then, good oil it is

speaking of which, im using cheap 10/40 oil at the mo, whats the best stuff to use? im thinking the castrol stuff, but what W?

and do fuel additives make any difference?

and can you recommend anything for an injection engine and a carb engine?

cheers ta very mooch

[dan16v]

[supernova1992]

[Welsh Dan]

Mine used to run on 15w40 GM mineral oil for ?8odd a can, its now running on GTX high mileage.

[BigStan]

I have never had a problem with engine flushes at all !

[Austin_Nova16]

Have always put a pint of diesel in the engine before an oil change. Run up till hot and drain. Engine flushes are a bit of a rip off really!

I've also always used 7.99 comma oil aswell, and never had any probs what so ever..
