Pentru motoarele mai vechi, eu nu v-as sfatui sa faceti un flush.

QUOTE
Flushing oils

These are special compound oils that are very, very thin. They almost have the consistency of tap water when cold as well as hot. Typically they are 0W/20 oils. Don't ever drive with these oils in the engine - it won't last. (Caveat : some hybrid vehicles now require 0W20, so if you're a hybrid driver, check your owner's manual). Their purpose is for cleaning out all the gunk which builds up inside an engine. Note that Mobil1 0W40 is okay, because the '40' denotes that it's actually thick enough at temperature to work. 0W20 just doesn't get that viscous! To use them, drain your engine of all it's oil, but leave the old oil filter in place. Next fill it up with flushing oil and run it at a fast idle for about 20 minutes. Finally, drain all this off (and marvel at the crap that comes out with it), replace the oil filter, refill with a good synthetic oil and voila! Clean engine.
Of course, like most things nowadays, there's a condition attached when using flushing oils. In an old engine you really don't want to remove all the deposits. Some of these deposits help seal rings, lifters and even some of the flanges between the heads, covers, pan and the block, where the gaskets are thin. I have heard of engines with over 280,000km that worked fine, but when flushed it failed in a month because the blow-by past the scraper ring(now really clean)contaminated the oil and screwed the rod bearings.

Using Diesel oil for flushing


A question came up some time ago about using diesel-rated oils to flush out petrol engines. The idea was that because of the higher detergent levels in diesel engine oil, it might be a good cleaner / flusher for a non-diesel engine. Well most of the diesel oil specification oils can be used in old petrol engines for cleaning, but you want to use a low specification oil to ensure that you do not over clean your engine and lose compression for example. Generally speaking, an SAE 15W/40 diesel engine oil for about 500 miles might do the trick.

QUOTE (georgem)
Si la mine uleiul anterior a fost cam murdar, era cel de la fostul proprietar si din ce-a spus el era Castrol 5W40. Sunt curios daca uleiul pus de mine va fi mai curat sau la fel.

Nu neaparat murdar, cat urat mirositor (cel putin asa s-a exprimat mecanicul, mie nu mi s-a parut sa puta smile.gif mai mult decat de obicei)..

QUOTE (georgem)
Totusi, eu nu stiu daca merita sa-i faci engine flush. Uleiul curata componentele interne ale motorului de depuneri si de aceea e murdar. Eu n-as face.

Am tot citit despre asta, cred ca ma calmez cu engine flush si o sa traiesc in continuare cu mirosul smile.gif

QUOTE (georgem)
Tu vrei sa schimbi uleiul dupa 7k km sau mai astepti?

Mi-au zis mai multi ca in RO nu prea e bine sa il lasi mai mult de 7-8.000 de km, mai ales daca ii si mai dai din cand in cand spre redline tongue.gif
La tine e ok cred, ca i-ai facut cam toti prin afara

De-aia am si hotarat sa pun 10w40, ca e si mai ieftin, e si ce recomanda producatorul..
Cu banii "economisiti" biggrin.gif imi permit sa il skimb mai des; ma gandesc ca mai bine merg 5-7.000km cu 10w40 decat 8-10.000 cu 5w40 sau 12-15.000km cu 10w60 sau 0w30..

Poti sa mergi pe un 10w40 semisintetic cum se recomanda dar e posibil sa-l manance daca motorul nu a suferit vreo reparatie capitala .
La golf mergeam cu 10w40 in condititile in care motorul era cota 1 de reparatie si l-am vandut cu 60.000 de km facuti in 2 ani aproape .

W30 ar putea fi cam subtire pentru motorul tau. Mai bine un *W40. Sa vedem ce zic cei cu pisici si alte masini de dupa '90.

marca ca marca
dar cand cumperi uleiul trebuie sa fii atent la specificatiile de pe spatele lui
API CL CF A2 A3 B2 B3 B4
si daca intruneste recomandarile producatorului respectiv
