Hi,
Which do you prefer?
For a common rail desel engine.
Motul X-CESS 5w40
API SN/CF ACEA A3/B4;
Or
Bardahl - XTC 5W40 (not version C60)
API SN/CF, ACEA A3/B4-12
They are on a same price!
Interested in answers too. Isn't the Bardahl advertised as part-synth only?
The Motul has quite ordinary specs but is fairly cheap here and it suits the Smart well. So far it is doing a good job keeping the noise low in the Smart...I wonder how it will resist shearing in an engine that is "harder" on oil.
