wot about castrol gtx magnatec 10/40 is that ok 4 the gtir?
Would steer clear of that matey. As Rishi has said, most peeps on here use Slikolene Pro S 10w50. They use it for a reason and that's because it seems to be the bet oil for the SR20DET in the GTiR.
I have used Mobil 1, Motul motorsport oil and the Silkolene that I have used for the past few oil changes is the best by quite a way. It quietens the engine down and makes things feel smoother also. Plus the fact, the oilman recommends it :lol:
No need to flush the engine at all, let alone after every oil change :? All the flushing agent is, is a thinner oil and I think, the ideaology comes from a long way in the past?! If you really insist of flushing the engine, just use some of the oil you intend to start using using. I.e. Drain the old oil, fill it up with the intended oil, run it around for 50 miles or so and drop that oil and old filter. Then put on a new filter and re-fill with fresh Silkolene Pro S 10w50
If you change the oil regularly anyway (every 6000 miles or so) the oilways etc... will be in top condition and the engine will give you many years of motoring joy..................well, until you turn the boost up too high
