EDIT DISCLAIMER: Am talking about modern high tolerance engines which have a default life of 2 lakh kms, sometimes goes to 3 lakh plus. Proof i can provide with snaps of cylinder block and pistons from a 60k kms run Crv engine. No flushing whatsoever but regular mineral oil change at 5k kms. Ref:

I am sure my statement is not 100% True, but not 100% False until one can prove it wrong by opening up his engine.
Better avoid unnecessary brand change with your blind trust over a engine flush!. Engine Flushes do nothing, Here is my proof: http://www.team-bhp.com/forum/access...ization-2.html
Believe me or not, its even not with the old oil. I HAVE CHANGED MY ENGINE OIL ONLY TO TEST OWS 210. But OWS works. It may be good for cleaning - but not for cleaning out the entire carbon or old oil.
I don't trust OWS until someone can take this challenge and open up his engine to prove me that OWS did MAGIC to his engine. That doesn't mean, you should not trust OWS. Its not bad at all and I love OWS 220 very much. I am just here to say avoid using your Car for unnecessary brand tests/comparison...
Also still now I dont find the logic of using old oil for an Engine Flush? How can you clean your toilet with the toilet water? |
Let me start on a lighter note, why would one believe any thing that has chinese written over it, unless its food!
Unless you frequently change the
grade of oils, or use very extreme blends of oil, there is absolutely negligible impact from change of brands as far as i know with modern automotive engines.
Engine flush if used regularly will give you pretty decent long lasting trouble free engine, please understand that engines are designed to take some amount of gunk in it. We are just reducing the amount of harmful oxidation and hard to remove gunk by doing flush. Yes one can go to extremes and use flush + flushing oil every 5k kms to keep the engine innards shining BUT cost benefits will be pathetic.
Manual decarbs are good BUT do we need to do it every 50k kms? Absolutely NOT! even if you do it, your engine will require an overhaul (minor one atleast) at 1.5 to 2 lakh kms and at that time you can do / will need to do the full clean up.
I would rather keep the engine healthy by using cleaning agents regularly and they will last the same. Aatleast in my experience, without any flush agents but flushing oil and regular oil change i had a zen engine run perfect for 1,50,000 kms. Performance drop will happen but it will be negligible and no amount of manual decarb will help avoid this metal wear out, maybe it will delay it by another couple of 1000 kms at the max. So is it really worth it, in my books NO! Unless its a 2 stroke engine where nothing but manual decarb works.
As far as toilet theory goes, one can always use flushing oil to rinse out the old oil and gunk.

It says it will help in minor water condenstation etc But no if its hard adulteration, take it to a garage and clean out and refill fuel and lines.

If you are a fanatic do it at 5k kms, 20k is optimum if you are particular. 40k is border line, from my experience of observing just the valve guides.

What I recommend at 50k is Off-car cleaning, you have to remove the injectors from the car and give it to Bosch or Lucas to check the spray patterns to make sure there aren't any streamers or problems. Sometimes you may need to reverse flush the injectors based on the deposits inside them to avoid clogging. I used to off-clean my injectors once in 3 months in my old 412 boat engine, but not necessary for a car.

Another possibility is that they use injector cleaning machines for modern electro-mechanical injectors (dont know if its the right term) they do a good job (spray pattern). Once clogged beyond a point, i would rather replace them though it will cost 5-10k depending on make and model.
Earlier days with pure mechanical plungers it was harder, since recalibration/overhaul was required. So best option was to use Bosch or Lucas service. Mostly thats the case with marine engines i guess.
