May I revive the Magnatec engine oil discussion?
Since Castrol rebranded Magnatec, they don't call the 10W/40 oil 'For Modern Engines' and the 15W/40 'For Conventional Engines' any more.
When the new oils came out, I contacted Castrol, who assured me that the old 15W/40 and the new 15W/40 are miscible without any problems. However, I have since found that 15W/40 Magnatec is becoming increasingly difficult to get hold of. And the price!
My question is - can we use the standard, and much easier to get hold of, 10W/40 oil?
Otherwise, what's the choice in UK, for an engine that has been running on Magnatec?
