How much gas smell in the oil is too much?

This is kind of a difficult question to ask because gas smell is obviously not something you can really measure lol. I was driving last night (car fully warmed up/mixed driving) and I checked the oil after and it reeked of gas, I'm not sure if this is a symptom of D.I. or if I have a bigger problem.

Is this something I can take to Ford and let them deal with or is it not a big deal? I guess I could call them but my dealer talks down to me like I'm an idiot whenever I speak with them about any issues.

I checked again today after my drive to work and it still was bad. I will check it again later when I head to school. I had a second person smell and they thought it was "gassy" too.

No tunes or anything of that sort.

From my experience most turbocharged cars are like this.

Maybe I'm just being paranoid, when I first bought this car it had 5 miles on it, 475 it leaked a shit ton of oil all over my driveway due to a "hole" in the oil filter (or so they told me, they never would show me the filter).

Funny you mentioned that, a buddy of mine('14 Accord) had the Honda dealer change his oil and he had a faulty filter as well. Had a pinhole. I guess it happens.

My 06 WRX always had gassy oil (never used any) and checking my dipstick on my 16 ST3 (10k) it's the same smell. I wouldn't worry about it unless it's using oil

Oil smelling like gas isn't too uncommon in general, whether it's a DI engine or not. I haven't noticed it on the Focus, but I've only done one oil change myself so far. Could be a sign of leaky injectors, but is most likely normal. Do you take a lot of short trips? If so, take it out on the freeway every once in a while and get it up to operating temp and put the engine through its paces to burn up contaminants.

A lot of mixed driving to be honest, it's combined. I wouldn't say my trips are "short" by any means but they're not long. I always let it warm up before really romping on it. Both times I've smelled it it's been warm so I'll try it later when it is cooled down.

That's totally normal, it's typical of DI cars in general. Even more so with a Turbo DI car.

Awesome, I was finding mixed results online. Still doing a oil-sample test though.

Oil sample tests are always useful, but every DI car I've seen or owned had a distinct gas smell in the oil.

At the very least an oil sample test will give you an idea of how well your oil is doing its job. Definitely worth doing.

Well I'm glad to hear I'm not going completely crazy. I figured it's only $28 and for the peace of mind I think it's well worth it.

How many miles on the car? Do an oil analysis with Blackstone Labs. They'll tell you if anything is amiss in an objective report. Costs a few bucks, but it's definitely worth it to know for sure the health of your engine.

Think of it like a blood test.. they can measure amount of water and gas in the oil, metal deposits, etc and gives you an idea of any internal issues or health that might not be noticeable from a normal inspection

8500 miles, I ordered a kit so definitely will be doing that as soon as it gets here.
