I think some fuel dilution is normal on these engines. I know my oil smells like fuel as well. Especially after 4-5k miles, it gets pretty strong. I keep my oil change intervals at 4-5k miles.

My previous Mercedes V8 Biturbo smelled like gas too. It's probably because of these engines using direct injection.

I wouldn't worry about it.
Yeah, thanks. I run 10% ethanol each time I fill up. The reading I've done suggests that doing so could well contribute to fuel dilution. I think its all good as I change the oil every 5,000 kms or so
Same, I didn't know that ethanol causes that. Thanks to California and it's crappy fuel (and roads) :
