how much oil should put in my s2k now it is s/c

 

About 5L as per normal. The extra capacity of the hose and SC chamber is minimal.

Drop in 4.5L then check the level. If it is off the stick add another 0.5 litre. Once it's on the stick run the engine up to temp, turn off and wait a few minutes then check again and fill to full.

 

10w30 mobil one synthetic on SC S2k?

 

just did mine and it took one full 4.5 litre can plus an extra litre, 5.5 litres in total.

I used "Castrol GTX Magnatec 5W-40" fully synthetic
