suspected fuel dilution

this is a new engine for Honda and they may have gotten in front of themselves again...if it is indeed fuel dilution and LSPI the warm-up must be killing it especially those running the spec 0W20 CAFE oil.
 
The Toyotas rev high on initial warm up as well, close to 1900-2000 rpm. So I put it into gear after a few seconds.

How you came up with that number is beyond me.

I'm curious...

On a cold start, how long do you let your car idle before you start driving it?

BC.
 
almost next to zero, it has remote start but rarely used..this is LSPI disguised by fuel dilution.

Not much wrong with Honda 0w20 if you don't do heavy towing in a hot desert area and then try killing off the block with too long an OCI.

Yeah I was thinking more like 12.5%
 
Dumped that diluted oil at 3k, refilled with the same Mobil 1 5/30..not using the Honda right now cause of the snow but look at the fill cap, geez this is at 7k overall.

All this guessing is worthless without a Used Oil Analysis. A few teas spoons of fuel in 4 quarts will smell of fuel because fuel is very aromatic. Ed

My '12 Kia Optima SX does this as well when it is cold. I HATE it. This is terrible for the stone cold engine but "great" for emissions.
 
The worst at this was RX-7s. They immediately went up to 3000rpm on a cold start. Probably since the catalytic converters spanned from the engine all the way back to the rear axle. Lot of ____ to light off.

For no reason at all, Lamborghini Aventadors immediately rev to 7000rpm on any start at all.

This "mayonnaise" is more a function of water than fuel and not unusual if you've short-tripped a bit during the recent cold spell. If this is after considerable highway driving you may want to point it out to your dealer. After they shrug and do nothing you may want to invest $20 for a replacement PCV valve.
