Hi,

I just went to www.castrol.uk.co (Catrol's web site in UK) and clicked on (bottom left corner) link "what oil should I use". I found out that for 2003+ 4cyl Accord Engine (I-vtec etc.) they recommend 0W-40 oil while here (US) 5W-20 is recommended.

Now, I know I have been going on about this but this really makes me believe that the only reason we (in the USA) are being told to use 5W-20 is for fuel economy purposes while Euro market gets (a better) recommendation to use oil that is better for the engine's longetivity?

Can anyone explain this to me? Am I missing something?

Thx
