About 1100 miles ago, I installed a catch can from Sxth element, and this is what I caught today. Mostly gasoline and water, and little oil. I did not expect this much in the blowby. My GT only has 3538 miles, so almost new. Has anyone else have similar results?
Also, when I was driving home from work this morning, I smell faint amount of gasoline after 20 miles (which is the distance of my one way trip)

Do you live in an extremely high humidity area?

My GT has just over 5K miles. I live in Florida - lots of humidity. When I empty the catch can it is PURE oil - not a watery mixture like in your picture.

When you open your oil fill cap what does the inside of the engine look like? Is it clear oil or do you see a white mixture like in your catch can?

yeah, if you're doing a lot of short trips (less than 10-15 minutes or so), especially if you're living somewhere that gets cold during winter, that sort of thing wouldn't surprise me
Yeah I had a falcon years ago and had a nasty motor built.. after a year of backing it in and out of my garage the valve covers sludged up and looked like blown head gaskets... I finally had a mechanic tell me to drive the hell out of it... cleaned right up.

I'm in San Antonio, which does get humid.
The oil in my engine looks normal, no "Irish coffee" looking mixture, nor on the dipstick.

Maybe I should let the car idle for a bit longer than 25 or 30 sec? Its been kinda cool here in central Texas this month.
Naw. No need to idle longer. Water and oil temps usually take 10+ minutes to get to operating temps. It needs to be driven a bit harder to boil out the water in the crankcase.

I have owned my Forte GT for 2 years now - and it has a little over 5K - so I don't drive it long distance much. When I do drive it, I intentionally take longer routes to keep trips over 5 miles. It is also garage kept. I do change my oil using the severe duty chart - 5-6 months...because I'm anal that way.

The OP stated in his first post that he drives 20 miles one way - that should be enough to burn off moisture in the engine crankcase. I would NOT be happy if the oil in my catch can looked like the OP's! Keep an eye on your coolant reservoir.

Talking about this subject. My GT is like yours, but mine has 9K miles. Do you recommend using a catch can on the GT? I've been debating if I should install one. I feel like mine has lost some power. Would the lack of a catch can affect its performance? I live on a small island, so humidity is all year long.

Based on your picture, how long did it take to accumulate that much oil?

Highly recommend it. It’s a direct injected engine, so it will help big time with carbon buildup on the backside of the valves, which will kill mpg and performance over time and requires expensive walnut blasting every once in a while to clean the valves.

I am just going to leave this here and let you judge for yourself. I know what the contents of my can are and have shown a short video here once before of it. My contents are the same as this video.

Yes, I recommend a catch can - if - IF you are diligent with emptying it.

The amount of oil in my catch can picture is from less than 500 miles.

While there is conflict over whether or not a catch can is effective the fact is that amount of oil would have gotten to the intake without the catch can.

Is there a recommended amount of miles driven to check a catch can? Like every 500 or 1000 miles or something more?
I read a Mishimoto instruction sheet where it said to check it every 1000 miles. In reality you should check it that often until you get a "feel" for how your car operates. If checking it at 1000 miles and it is only 10% full of oil you can check it at 2000 miles - and extend that if the oil level still stays low - as long as it never fills to the level of the internal separator.

Wow!!! Really? 500 miles that's not a lot. I haven't checked tc0566's video. I will now.

Any preference brands? I know Panda sell them. I will check that too.

Thanks a lot!

SXTH Element makes a really nice one if you can stomach the price.
