Is It Advisable To Use Engine Flush After Every Oil Change?

[jarthel]

as title.

thank you

i would use it once and then not use it again for a very long time. many people would even suggest not using it at all. you are basically putting solvents (kero?) in your engine which thins the oil. the best bet is to use good synthetic oil and change it very regularly.

how about:

1. drain old oil

2. engine flush

3. liter of cheap oil to clean it again

4. 5L of syntethic oil

drain old oil.

new filter and good synthetic oil.

drive.

[raps86]

if u use engine flush put it in before draining the old oil. put it in take the car 4 bout a half hour drive to get it throught everywhere then drain the oilfor at least 20min 2 let all the oil possible out then put sum synthetic oil in.

[SECURITY]

doesnt motul turbolight have a cleaning agent kind of thing? or was that 300v?

just use that if you're worried.

[raps86]

u will find that quite a few of tho oils now have sum sort of cleaning agent in them. in my old ss when i bought it i knew the oil hadnt being changed for a year. i draind it put castrol edge in it and 4 the 1st 2000ks it was taping its head off then done another change after 4000ks with the same oil and it was all sweet

A friend of mine used to work at nissan, anyway his brother had a piece of shit kingswood and was fixing some stuff on it, and serviced it fairly regularly (brother has no idea about cars) He replaced the rocker cover gasket as was leaking and noticed heaps of burnt on crap on the head. Anyway getting to the point he started using shell helix oil (they have in the big drums) and after a few services he had the rocker cover off again and noticed that where the oil was running it had cleaned alot of the areas up. Most good modern oils would do the same. So regular servicing with good oil is all you need.

as above:)

1. add oil flush to engine oil (wynns/nulon etc..-> a good brand)

2. turn on car and let it idle for a period of time... (every bottle says a different time..wynns ->15-30mins/nulon ->10-15mins)

3. drain old flushed oil when warn!!!! use a 14mm socket to undo and its anti-clock wise...

4. replace sump-plug washer, when all old oil all drain out, should take 5-10mins.. if that!! and put back in!!!

5. *MUST* replace oil filter (a must when using oil flush!!!!!!)

6. *MUST* replace engine oil, with good oil of your choice!! ( a must if you want your engine to run!! lol )

7. check ur dip-stick to see how much oil you've added, i believe rb25det is around 3.8L...(with a oil filter change)

8. put your engine oil cap back on..and shes ready to GO!!!

but there's no harm doing a engine flush like once or twice a year..just to make sure..

just did it to my r33 s2 and it just went past 100k's

seemed fine after...probl. do it again wen i hit 115 to 120k's..

hope this helps...

IMO..

If used from the first time, yep, use it.

BUT, as I have made more than one engine rattly having used it, I'm not sure wether it is a good idea on a good engine.

Generally this stuff is good for diesel engines IMO, and that is it.

Good rule is to use good oil, always run the engine to normal temp if you fire it up.

Lets just evaluate what this stuff does... it removes varnish type deposits too, and this CAN affect the compression. IT DID take enough out of the bores of a hydraulic valve lifter for me to actually make it rattle thereon. Admitedly the engine was nof unknown history.

Mate, the oils are pretty damn good now in the modern world, and there are additives in them to assist in engine cleanliness.

Not saying dont, but its your call.

GOOD OIL FILTER is very important though.

Just my 2c again!!

I wouldnt even worry about using an engine flush, some people believe not to and other people swear by it. If you change your oil and filter every 5000 km's and use decent synthetic oil then u shouldnt have any problems. But dont put it in after u change your oil and filter because if u had a flush in it and ran the car with it in until its next oil change, i reckon it may do some harm. And if u do use it you only really have to run the engine for 15 minutes or so.

I dont believe in engine flushing myself, it thins out the oil, and no matter how long you leave the engine oil draining, there will always be old engine oil with flush still left in the engine, mixing with the nice clean oil and fouling it up with the flushing agent.

Personally, for my first engine flush I do on a new (newly bought 2nd hand) car, I drain the oil, replace the filter with the cheapest reputable (valvaline or similar) filter, fill with new clean oil, and take the car for a drive until it reaches normal operating temperature.

After it's reached temperature, I come back and do another oil change with proper synthetic oil, another new filter and then she's sweet from there on.

Doing it this way, the engine oil originally in the car is removed, new oil (not a shit oil, but not $90 oil) is run through the engine to flush out the old oil, then drained. Once that's done, the actual running oil is put in, and she's run on that from then on.

Each oil change after that is simply oil and filter every time with decent synthetic oils.

I used engine flush once, and it thinned the oil, took away the carbon and other impurities that where stopping tappet rattles and other issues, and the engine came out rattling like an old tractor, so never again, if it is running good, there is not need for flushing it completely.

NO. Its not advisable to flush your engine every engine oil service.

You will be changing your piston rings and bearings every 40,000 to 50,000kms.

Using high performance engine oils will do. Just keep a 8,000 to 10,000km engine oil service intervals for fully syn. oils you will be fine.

Cheers!

I know this is an old question but I used some supercheap auto flush on my sr20det motor and 10 minutes later 1 of the bearing started rattling. Cost me $500 to get new bearing shells fitted
