The 540/6 has about 230.000 kms on her. Mechanic who works on it say's she's in good shap(he has worked on for many years). Alway's maintained and yes it's it's a nikisil, uses less that a litre of oil/5000kms. Just like some thoughts if a E.A.T chip would work better than what I already have which is a Dinan chip which was installed before I purchased this car. Cheers
