Buna.
Articolul indicat este foarte interesant:
"* Diesel oils rank overall between number 15 and 109. But, if you omit the highest ranked Diesel oil which is FAR, FAR MORE CAPABLE than all the other Diesel oils, the rest only rank between 58 and 109. The poor wear protection performance of all but the one particular top ranked Diesel oil, makes it very clear that in general, Diesel oils are a poor choice for High Performance gas engines." - adica o fi el cu mai mult detergent dar nu cred ca e bun pentru un matiz
"• BOTTOM LINE: Thinner oils are better for most engine lubrication needs."
In acel clasament nu exista aral, elf, total si producatori proprii cu exceptia GM.
Deci din clasament cunoscut ar fi Mobil 1, Castrol, Valvoline, Havoline
Ps: experienat mea cu GM dexos 2 5w30 pe un matiz din 2007 - dupa schimbarea uleiului la aproximatix o saptamana s-a aprins becul de motor - MIL. Eroarea era P0133 - adica raspuns intarziat la sonda lambda. A disparut doar la schimbarea uleilui cu unul daewoo 5w30 - iar asta era fara C-ul pe care il are GM - care apropos era long live.
