There may be oils as good as Mobil 1 synthetic but there are none better. I've seen cars go over 300,000 miles on this stuff with no engine failure. I use it and still chnge the oil every 3000 miles. Good stuff and not that expensive at Walmart.
Yeah but...do they have Wal-Marts in Romania?...
I'm seriously not being a wise az here, I just don't know.
