Saw the recommended 5-30w for Civic Type R 2001- in Halfords few months back. Asked guy who said I needed to get the 10W-40 out of my car pretty much there and then. Told him I had managed nearly 2 years with it so no rush. Spoke to couple of Honda dealers who said the oil i'm using is fine.

I just bought 12litres (6x2litres) of Motul 300V 5W-40 from Opie Oils.... £79.95! Thats enough for 2 oil changes and topping-up. I believe that Mugen reccomend 5W-40.
Spoon Sports also recommends Motul 300v 5w-40.
Funny enough although Mugen uses Motul 300v 5w-40 on their race cars I have no idea why they bought out their oil brand. Perhaps it could be Motul oil rebranded :|
so basically what we are saying is not to use mobil 1??
mines in for a service tomorrow at dealership, not sure what they use though, i'll have to check, car has 23k miles on clock, so what would be the better oil to go for?
