Anybody have knowledge of this oil? I can get it at USD 7.7 pr liter and that's 1/4 of Castrol SLX 0W-30 at USD 32 pr. liter and 1/3 of Mobil1 0W-40 at USD 23 pr. liter here. The Fina First has API SL, ACEA A3/B3/B4, VW502.00 (and more) and some MB approvals. Since Castrol and Mobil is so expensive here, I think I will make a swith. That do you think? The engine in question can use all VW502.00 approved oils.
