My car, 2004 with 70,000 has started using about 2 litres between services (that's 2 top ups) and when hot the oil pressure varies between 25 at idle , 43 at 2000, and 60 at max revs.
I get a regular service at a Bosch service centre (I've found one that cares) and let them supply 5W 30 semi-synthetic. Would my car benefit from a better oil and would I see better pressures and lower oil consumption ?
