burning oil on a is350
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?
