Do NOT engine flush

[Yewheng]

I'm still confused. I am thinking of doing the engine flush for the next servicing package coz just got a second hand car. I see terms like engine flush + treatment, fuel Additives + Fuel Injector + System Cleaner. Are they all the same meaning of engine flushing? Some bros mentioned use mineral oil n run for certain km, then change oil again. I mean, for layman like us, we dun know how to DIY, n I dun think the workshops advise or do this for us. We only go for our regular servicing with or without engine flush. So, in conclusion, experts pls give correct advise. Thank u very much!

 

Ok, Engine flush is using a chemical that can clean engine but at same time can also clean off seals that causes leakage. Excessive dirty particles that is inside engine oil if use engine flush may cause the dirt particles to get stuck at joint opening. Think of it this way, the slump is at the side of the pipe, if using chemical to remove the slump, the slump yes will come out but where else can the slump run to?? End up it get stuck somewhere further and accumulate a lot that can choke the pipe. ( In layman term ) .

 

Fuel injector + system cleaner is a liquid that is poured to petrol tank that clean up fuel system. But than again it is quite useless as everytime top up petrol finish will close back and as long as got constantly top up petrol, there is no issue here of tank being rusty, dirty etc.

 

Mineral oil is a cheaper oil as compared to syntactic oil and will lose it effectiveness at 5000 km. And people recommend using mineral oil to run for a few hundred km than go back drain off the mineral oil and top up with syntactic oil according to one preference on which brand driver want to use is because by running for a few hundred km on clean oil, hopefully some dirt particles can come out drain off together with the mineral oil when doing oil change after running few hundred km and thus clean the engine.

 

If you regularly go for servicing there is no need to be so ma fan, just go with the normal servicing package can already. [laugh]

What about those new technologies that use gas to clean out the sludge? Any gurus here can share their views?

[Relagsingh]

I remember my 1st service experience when I saw how they do engine flush. During then my job was working on marine engines and generators.

 

When I asked the mechanic whether is that how they do it, they sell koyo until very song and he said everywhere does it the same way.

 

From then on, f**k engine flush.

my answer easier than yours right?

Drain oil and then pump magic gas into the engine parts?

 

How to run the engine without lubrication?

For old car, try this. Much better than any engine flush in the market:

engine flush is to make your clean engine cleaner. However, if yr engine is DIRTY, do not attempt to flush it. It can be a DISASTER.

 

If engine is clean ,theres no need to flush.

If engine is dirty, see above quote

I do my general engine repairs by myself and replace its oil on a periodic basis that gives me more power output which keeps my car as new. Such tips effectively help me to flush my engine that I have found with http://www.hiperformer.com/engine_basics page where experts have provided all essential engine DIY guidelines.

I think when your engine is pretty clean, flushing won't cause much problem. But then, if it's pretty clean, then no point flushing. What's more important is regular engine oil change and to utilise your car regularly.

 

The most missed point about engine oil change in Singapore is, most don't clock the extended interval of 15/20K or even 30K within 6 months, and most motorists change engine oil only in accordance to distance clocked, and not distance clocked OR 6 months whichever comes first.

I saw that car lube sells a flush for like <$10.

 

Says

 

-Pour into engine oil sump, and let idle for 10-20 mins

 

- do not drive the car as will heat up very fast

 

Hence, I thought, next round, I drive to ws, park somewhere near, & do the above......then let the are "creep" in D mode to ws & change eo as per normal.

 

From what I read from this thread, don't seem like a good idea...

it's never a good idea to flush.

Yeap, not a good idea.

 

Flush are usually solvent. Solvent does not lubricate, it dissolves. That's why you have to get it out of the oil system.

 

If the engine had crud and sludge along small oil lines and it dislodged with a power flush, that will block oil from moving and starve the engine of lubrication and oil cooling.

 

The gentle, albeit longer way of cleaning is simply use high quality detergent engine oil, which most branded engine oil already are; some with more cleaning power, some less.

 

Change out oil more often and you're cleaning it at the same time.

In this case, which u think is a better idea. Based on 13k /yr mileage. ?

 

a) Use CL, change every 6 mths

b) Use Mobil1/Agip/Helix Ultra change once a yr

[Knoobie]

In other words, the best way to clear slumps in your engine is to strip it down and clear it using petrol right?
