My 2006 IS250 is supposed to take 6.3l with oil and filter change. I've done it twice now and with the oil half way up the dip stick where it should be it is only taking 5.3l.

Due to jack the car is leaning slightly towards the sump plug to aid draining and I have waited until no more oil comes out before refilling.

1 litre is a lot of oil to be short of the manufacturer specs. The first time I thought maybe I had not given it enough time to fully drain but this time I am certain.

Note: I've let the new oil run through for a bit and the level hasn't changed. If I put the manufacturer spec levels in it will be way over filled but this just doesn't feel right given the owners manual and everywhere else I look says 6.3l

Does anyone know why this would be? Any advice on what to do?

Thanks,
Shannon

Hi,
Thanks for the reply but I'm not sure what that is trying to tell me?
I'm well aware it SHOULD take 6.3l. My problem is it is only taking 5.3l and I don't know why.
Thanks,
Shannon

Not to be a smart a$$, but did you drain the engine oil and not the transmission fluid? I’ve read here that someone actually drained the fluid from the transmission pan instead of oil pan, then filled up the engine with more oil. Things happen, people rush, make mistakes.
Let’s just clear that this is not the issue in your case. I’m trying to figure out what causes your problem. When you drained the oil and replaced the oil filter, have you verified that there’s no oil on the dipstick?

Hey,
Haha yes definitely the engine oil, but always worth checking!
No I did not check dipstick after draining so I guess it is possible there was still some oil left in the engine, but it was left to drain for ~30 mins and nothing more was coming out...
Cheers,
Thanks,

Probably captain obvious here but did you remove the oil filler cap during the drain step?

SRowe

hey yup that was also removed drained and replaced.

I wonder if the dipstick in your car is the right length? Or maybe the oil pan was damaged and replaced with the different one or from the different model? Are you the original owner of the car?

SRowe

Hmm that’s a good idea. I’ll try find out whether the dip stick and oil pan are the official part. No the car was imported and I’m the first owner since import, so your theory is definitely possible.

thanks!

Does your oil dip stick look like the one on this thread?

It would look like that with the full 6.3l in it yes, although I don't notice any difference in level hot or cold.

With 5.3l it sits perfectly in the middle of the two dots; where it should be.

Based simply on google images it does look like the dip stick and oil pan are genuine - they both look identical to the genuine parts I have found for sale. Oil pan is in good condition too, no big dents or anything that could impact.

The value given is a reference value, and would typically fill to the top of the dipstick on every Toyota/Lexus I've ever worked on. That accounts for roughly 0.5L or so.

How level was the car and how long did you let it drain? Additionally, what are the conditions when you checked the level on the dipstick? The level should be checked after the engine is at operating temperature, then turned off for 5 minutes.

My recommendation to get the most oil changed would be to get the engine to temperature, drain, fill, run engine again until oil is up to temperature, stop engine and let sit for 5 minutes, then check the dipstick.

All that said, the correct level of oil is what the dipstick registers, as I said the value given is for reference only.

Ok thanks Jeff. To your points:
Car was fully level and I allowed at least 30 minutes to drain - there was absolutely nothing coming out of the oil pan plug or filter before I re-filled.
Engine was run in, but only for 5 minutes so may not have been up to operating temperature when drained.
Engine was not off for a full 5 minutes before drain.

Based on your comments I'm better to fill to the top of the dipstick (currently sitting right in the middle) which will mean adding a further 250ml or so. Next time I do it I will make sure I run the car for longer and allow it to stand 5 minutes before draining and see if that makes a difference.
