D1-30F oil capacity

[Username25]

Please help with oil puzzle. Pumped out old oil with Pela 6000 via dipstick, changed filter, added 3.2 litre of new oil (according to manual oil capacity is approx. 3.5 litre), started engine for 5 minutes, waited 10 minutes.

Checked oil level and it was well over MAX level. Strange.

Checked old oil capacity. To my surprise just 2.0 litres were pumped out. WTF??? Pela tube went fully in, at the end I could hear air sucking sound. Plus I have inserted tube several time just to make sure all oil was out, but apparently 1.5 litre of old oil was left in the engine.

How? Where? Any ideas?

Also wondering should I put dipstick fully in or just yellow plastic part should touch the metal tube?

Instead of pumping oil out the dipstick tube, you should suck the oil out via the dedicated oil change/ removal tube. It's mounted on the stb. side of the engine and pulls from the very bottom of the oil pan.

When checking oil level push the dipstick all the way down in the metal tube until it stops.

I could hear Pela tube hitting the bottom of the oil pan via dipstick, so draining oil via drain pipe should suck just few additional millilitres. How it could be 1.5 litres?

The bottom of the D1-30 oil pan is not flat over its whole length, but is stepped with the deepest level in the rear toward the flywheel housing, where the factory suction tube is located. Most likely your suction tube thru the dip stick was not hitting the lowest level, therefore not pulling out all the oil.

On the engine photo it looks like dipstick tube positions/direction should let suction tube to go all the way down to the lowest level of oil pan.

Some of your "missing" oil is in the oil filter.

Well it is. New filter weights 200 grams, old one 470 grams. Considering density of oil about 800 grams per litre... old filter holds additional 250 ml of oil.

The suction tube inserted in the dipstick may or may not go to the deepest part of the oil pan....

Next oil change suck out thru the dipstick, then try and see if you can get any additional oil out of the evacuation pipe. That will tell the tale.

Thanks. Just sucked out via dipstick tube about 1 litre to get proper oil level (almost at the MAX mark). Seems about right as 2+1 litres out, 3.2 litres in.

Now I have mixture of old and new oil. Should I change oil sooner e.g. at 100 hour instead of 200 hour as per manual?

Also evacuation pipe cover seems fragile. Is it just a rubber cover? Looks like Volvo changed it to normal plastic cover.

Change the oil at the end of your season, or 100 hours.

The old type oil pumpout tube cap was just a rubber cap, but was a bear to get off, so I imagine that's why they changed it.
