I wouldnt go for a 5-40 personally

a 10w60 is proven to be unstable and breaks down to a 10w50 very quickly.

with a t2 and only minor mods a 5w40 or 10w40 would be ideal, using too thick an oil and not getting into it's ideal temperature range is a good way to make your engine struggle and lose power

I dont agree

But yes a 10-40 would be suitable

But as Adz said personal preference

which bit don't you agree with?

ok, 5 - 40w 76 oils it is

i just hope my mate doesent come round asking for the oil back, to find only half a case left.......

i don't agree with the bit about the oil breaking down either, if it does break down like you say , what is the point in using thinner oil, surely that would break down even further

it's a proven fact, the larger the gap between the numbers the more unstable the oil is, castrol RS loses it's viscosity after about 2k, there's been a massive oil analysis thread about it on SXOC

thinner oil will give better protection at startup, if you understand correctly what the viscosity ratings mean

yeah i do understand, is it just that oil that does it or is it all of them

I change my oil at least every 2k anyhow or soon as its not clear on my dipstick

.But if it only breaks down to 10-50 then its not going to cause any problems. Sxoc prove castrol wrong. Sxoc really must have a lot of paid members
After further thought though 10-50 is probably the best choice for the ca engines but i dont think Castrol RS is going to do any harm at all and is still a top choice of oil
