Just done an oil change on my aaz which has a front mounted oil cooler. I put the front end on ramps but ive never been sure how much drains from the cooler and pipes . about 4 litres came out and I put 4.5 in. Should that do it or should I add extra for any that drained from the cooler ( dipstick works but not sure how accurate as it was from my old cs block) thanks.

When I change the oil I just drain the sump replace the filter and check that I've used near 4.5ltrs.
I don't drain the front mounted oil cooler!

Thing is I used engine flush so there could be 50 ml or so still in there
