VSC - Check Engine: Excessive gas in Oil???

Perhaps that explains why it appears to affect more IS250s (which are direct injection only) than IS350s (which use both port injection and direct injection). FWIW, I do lots of short trips on my IS350, and haven't had this problem.

When the car detects fuel in the oil, it throws the CEL light. This explanation made sense to me. For the last month I have been taking many short trips as I drive 5 mi. each way to the bus stop to get to work in 10 degree CO weather. Anyways, I was wondering if anybody else who has been having this problem has been taking short trips in their IS.

I too doubt there is a sensor that checks to see if there is too much fuel in the oil. Anyways, I thought I'd include the comments that were on the invoice. "Excessive fuel odor in oil 151011 T1=15 T2=99 50 replaced engine oil and filter advise customer to drive less short trips need to allow engine to get to full operating temp before shutting off." Hopefully, the code doesn't flash again. I agree, there needs to be a fix for this.

After owning 36 cars, I have never had to either avoid short trips, or purposely drive out of my way so as to go a longer distance. I have to think that there is a solution to this problem other than telling me to drive further. I did not have to worry about short trips in my Audi A4, Audi S4, or BMW . Surely I don't have to do it now.
Not incidentially, I have though since I bought my 250 AWD that the idle is higher when cold than it needs to be and the fast idle is maintained longer than it needs to be. I suspect that this is the problem and not my driving on short trips. I like being able to get to the Hospital in 5 minutes so I don't want to have to give it up. I'll change cars first!

There's obviously a software issue, though whether or not it's caused by an actually mechanical problem is going to have to left to Lexus to determine.
