Default burning oil on a is350

Hello everyone,

been lurking on this forum for awhile gaining knowledge from all of you smart folks!

needed some help. I changed the oil on my car and because it was a little colder than normal out, decided to let the oil change go for 8k. I use toyota synthetic 0w20 and was told i could probably go to 10k, so i figured i should be ok.

My concern is that when i drained the oil only 5 quarts came out when i put in 6.5! So this has me a bit worried and upset that i didn't check the oil sooner.

1. is this normal?
2. did it cause any damage not having the full 6.5 quarts of oil in there?

i wouldnt really stress it. that much time driving you have to expect some of it to be gone. but at least you didnt check the oil and only 2 quarts came out

1.5qt over 8k miles isnt too bad! Also, that would only put your oil level at the miminum low end so i would not worry too much about it. I would recommend check the level every couple thousand mokes and top the oil off if it makes you feel better.

0w20 is a very thin oil and may burn off faster... Do you really need such a thin oil? The recommended weight is 5w30 and should be good for use in temps below -30...

i thought about the weight of the oil as well, but the new IS350's are spec'd with that oil and from my understanding the engine has not changed at all? I also read multiple threads over at bob is the oil guy and the difference from a 20 weight to a 30 is not much. I decided to use the toyota 0w20 because it has a bunch of moly and is supposed to help with cold starts. I am going to go back to 0w30 and see how much it burns.
