Fuel Smell in Oil

Just dropped the oil in my 2015 300 SEF-R Factory and the oil smells like petrol. Doesn't feel too bad (still slippery) when pressed between fingers. Anyone else experienced this? Engine has 20hrs, first oil change at 5hrs, second one at 10hrs and this third one at 20hrs (so 10hrs on oil). I had smelt petrol in previous oil changes but this is bugging me as I've seen the consequences of fuel dilution on engines before.

Get your efi fuel map checked might be on the to rich side and hav excessive fuel wash due to incorrect efi mapping
Note...having a slight fuel smell on any 4 cycle engine is normal but excessive fuel in oil is not good

Did you notice if it was making oil, I think i have a similair issue with my bike, seems to run rich.

How many kms per tank ?

Looking into a power commander for it.

I've Heard this is common in modern HP 4 strokes, high comp, tiny piston, minimal rings can cause blow-by and contaminate/dilute oil.

This is the main reason the oil change intervals are so short.

I am no mechanic though.

Injector could be leaking while your not riding it also which will raise the oil level and dilute it.
I'd just change it more regulary and monitor the amount of oil that comes out.

Very common. Drop the oil at shorter intervals for piece of mind, especially using a non fully synthetic variant of oil.
