No in the main no, most diesel oils carry petrol specs and vice versa.
Most oils would state for example ACEA A3/B3
A=Petrol
B=Diesel

Don't discard it, just swap it every 3000km/3months. Technically "changing" the oil as required!
I think my MB Vito looks at the oil optically in a transparent tube within the engine and when the light source shining through it becomes obscured to a certain level due to increasing opacity by dirt, it triggers the service interval warning, although mileage and driving conditions also play a part in the calculations. In MB's it's known as ASSYST. This could be correct or total cobblers but it's what I was told. Can anyone confirm or deny?I believe its worked out over time and how the car is used.
So, if the car does lots of short stop, start journeys from cold then the computer is likely to want a service in less mileage and time then if the car was used for long distance motorway cruising, which oil likes.
Can it be trusted... who knows but the coreect long life oils can go the distance.

Hi All
A question for OILMAN - the guru of oil-sensibility and anyone with oily - techie knowledge.
I need to change oil on my C class CDI 220. This is my first attempt.
Can I mix two different types oils - namely:-
CASTROL 10-40 (API SJ; ACEA A3/B3)[5 litres] and CHEVRON SUPREME DIESEL 10-40 (MB 229.1; API SL/CF; ACEA 13-02, B4-02 & B3)[2 litres]?
Also, how about CASTROL EDGE 0-30 (APS SL/CF; ACEA A3/BB/B4; MB 229.3/229.5)[1 litre]?
The reason for the 'mix-up' is that I have left over cans that I would prefer to use up.
Your advice would be invaluable and appreciated.
Regards.
