Oil Smells Like Gas
I can smell gas in the oil on my dipstick when I'm checking the oil level. Bad news? What are some of the possible causes? Blow-by? Leaky injector(s)? Anybody have this experience? If so, were you able to fix the problem?

Send an oil sample to Blackstone Labs to see whats really going on.
Oil is a petroleum, so is gas. It's normal for it to have a bit of an odor after being in a combustion engine.

My car runs fine. The gas smell is fairly strong, moreso than what oil smells like. I think my car burns some oil which leads to my suspicion of a bad ring/blow by.....have any of you ever repaced a ring on your Maxima's engine? Isn't that a pretty expensive job? Should I just not worry about it? I mean the engine does have 170k+ miles. Maybe it's just time to upgrade to a G35 coupe or something.

well if you can afford a G35 do it 
but until then, change your oil (assuming its not brand new) do a compression test, just some generic diagnostic procedures to make sure it wasnt just a 1 time thing. just my .02 though

It's normal.
It is fine! My oils smells a little like gas. Car works fine.
You know, that oil DOES go through the pistons. Gas goes into those pistons and combustion takes place. I think it would be kind of unrealistic to expect your oil to stay like new after it washing around the cylinders.
I say that if your car runs fine, do not worry about it.
If you want to test your rings, do a compression test.
Edit: Oil washes around the cylinders. Not the pistons heads. Just the cylinders around those pistons.
