Petrol Oil in a Diesel?

[Dave VXR]

Mate just came down in his Cavalier 1.7TD.
Went outside to start it and engine was very loud, viabrated like a B*tch. Oil level was low
Asked him if he wanted some oil but he had some in the boot. So i looked at it it was PETROL oil. He has already put most the bottle in the system

Is it best to drain the oil out?

[Andy]

it will be fine

well, its nearly 20 years old...... the grade of 'petrol' oil is probably about the same as the stuff they put in it when it was new.... i don't think it will kill it, when did he last service it??? aren't they on 4500 intervals?.

[Dave VXR]

Was serviced 3 months ago... unsure on service intervals.
its 15w-40 oil his put in it.
