pistonheads! got a 1.9 Audi tdi, 1999 (pre pd) and a corsa c 1.0, petrol, to oil change. I got a "can" of 10/40 and a can of 5/30 fully synthetic. Thought I'd just give em both a 50/50 mix. you think this be ok?

How about finding out what kind of oil each car actually needs and putting that in?

Just bunging in a mix of whatever you have might work, but doesnt sound like a good idea.

well, officially Audi would recommend a 5/30 and it's probably the same for the Ford, but both are high mileage engines, 205k on the Audi and 105k on the Ford. My understanding is that thinner oils aren't always the best for worn engines.
also, I happen to have these oils without buying any more

That would make 7.5/35W if both 'cans' are the same volume. Bung it in chief.

Put the 5/30 in the Audi and the 10/40 in the Corsa and let us know how you get on.

One is a trubo charged diesel and needs oil suitable for a turbo charged diesel, the other is a naturally aspirated petrol and needs oil for a naturally aspirated petrol. The "weight" 10w40 is a range, the spec is the important bit.

For engines of that age tbh I wouldnt worry about it. The tolerances will be well fked by now and as long as it has some lubrication going round it wont come to much harm.

I disagree with those that say put any oil in
If the cars are running well you dont want to speed up the wear and tear .
The tollences will be out yes but that is no excuse to increase the wear on the engine

So I would say a good quality oil at the grade the manufacture recommends

Any old oil your not sure of .........Put it in the oil can and oil the garden gate !!!
