full synthetic 5W30, 5W40, 10W30 or 10W40 would be fine. I use Elf 5W40 full synthetic in my 200,000kms 4G63 Evo engine and it doesn't use a drop.

woulda thought a 30 hot weight oil to be too light for a 4G63. if using it hard that oil would get pretty darned thin.

5k if it were mine - oil is cheap insurance on a performance vehicle

Not for a 10 year old 4G63. 30 weight is just fine. If it were pushing 400+hp on a standard bottom end then I would probably move to 40 or 50 weight.

Their marketing department has done a good job then. There is nothing special about castrol oils. If there were they would have a lot more presence in motor sports.
I use Total lubricants 5w50 full synthetic. But then again I get that for forty dollars for five litres.
yeah 5w30 is fine, thicker oils seem to make lash adjusters tick

i'm not for or against castrol but to get your info straight from castrols site doesnt really say diddly swat. How many manufactures do you know bags down their own product on their own website. try one from another reliable source be more credible.

I think clark20 is meaning castrols involvement in motorsport.Where it was mentioned earlier that they didnt have much involvement

Castrol have had significant involvement in lemans (probably the most demanding motorsport event on earth) for a very long time.

The only way to know how well a oil is going in a particular engine is to sample it, end of story! Manufacturers can whip up any tripe but the proof is in sampling, makes me laugh when someone swears by a certain oil that its the best, but they have never done a sample on it, just manufacturers spin doctor at work.

Proof may be in the sampling, but how many oils have been proven to be at fault, rather than using the wrong grade, it got too hot, it was used for too long, it was not topped up, it had contaminants in it, the engine was worn, the pressure wasn't high enough etc etc

Thats the whole point in sampling, it will tell you if you have contaminants (fuel,water, debri), if it was used for to long, excessive wear, its got to hot and the oils broken down. But how else do you prove that a oil is doing its job properly and not causing excessive wear! Listen to the oil companys spin doctors!how does saying a certain viscosity oil is the best! when one of the main things in oil is it's spec, if it doesn't meet a certain manufacturers spec then the viscosity doesn't matter at all.
