i was reading this debate about Mobil vs Castrol. I have jused in my XC70 2010 year model with D5244T10 engine Mobil Super 3000 FE 5w30 over 2 years and i live in Estonia where weather is colder then in UK. And i have no problemos
difference in 0w30 or 5w30 is so little. And Mobil Super 3000 FE 5w30 meets
ACEA A5B5, API SL/SJ/EC, ILSAC GF-3. And the Castrol is not some golden oil its just oil that volvo gets very inexpensively from castrol to but in engines on the factori. My point is... Mobil 1 is same **** like the castrol 0w30 the difference is very little.
