I just checked out Castrol Canada's website and it now lists 5w40 under the Syntec lineup (it never listed this viscosity before). I know the Belgian made 5w40 Syntec has been spotted in some rare locations (such as imported car parts stores), but in order to list something on a major website like this, you'd think it would be more widespread than that wouldn't you? (such as being sold at Walmart or Canadian Tire) So has anyone spotted 5w40 Syntec in any major stores in Ontario yet? I sent Castrol an email asking them where this oil is sold so we'll see what they say. How common is the 5w40 Syntec in the US? And is it only made in Belgium, or is there a US made version too?
