It's been about just over 3 months since i did my oil change on my IS250. I filled castrol magnatec 5w30 A1. At that time i drained around 5.6L and filled about 6.2 or 6.3L as per Lexus specs with the Oil filter change. I think the level of oil after the change was around the halfway mark maybe a little over the half way mark.

I'm about 300 miles away from completing 4k miles since the oil change. I checked the oil level today on the dipstick and i'm shocked to see that it seems that the oil is now on the low level on the dipstick. I've checked for visual leaks, nothing at all. I dont have coolant in oil and neither do i have oil in coolant. Exhaust does not have any colored smoke. So i'm concerned where all this oil has gone and what can be wrong.

 

Did u check for smoke while full throttle?

 

if your not leaking oil your burning oil. how many miles do you have?

 

149k miles now. Would anyone recommend engine flushing before the next oil change?

 

sounds like the car is burning oil to me from the description. at least if its not leaking at all
