2023 Hybrid Oil Change Pudding Surprise!

[Jared]

Moisture in the oil. Due in part to your climate, lack of longer trips. Could also be an issue with coolant leaking into the engine oil.

5K miles on my '24 Hybrid XL. 8.6 miles each way to work. I see the vanilla sludge in my cap. I have been using the engine block heater during the week last fall and this winter. The heater is on for about 1.5 hours in the morning before l leave (it is on a timer). Truck is always in the garage - never outside overnight. I start to get heat after about 1/4 mile. Not much but I can sense it. Oil on the stick looks fine.

I would think that the cap being plastic and high up and out of the flow of things, would naturally be a cool point, so a natural place for condensation to form. Even when the engine is hot in the summer, you can always grip the cap to open it and not get burned. Hmmm - maybe I need an oil cap heater? . I usually drive in standard or eco mode. This week I will start off in Sport mode and see what the "extra heat does to the cap accumulation.

If you have the factory block heater it is on the coolant, not the oil pan. At least that's my understand from how it was described by a Ford tech on here.

My 2 cents.... condensation from engine not reaching and maintaining operating temperature long enough. Had the same issue with that white goop on the oil filler cap. It was on our 1998 F-150. My wife had a 2 mile commute to her work.

Exactly!!!

Yes - it is heating the coolant. It goes into the firewall side of the block. You can hear a faint "fizzy" sound when it is on.

Good to know, I've only used mine once when it was -12F last winter. I never sat around to listen to it.
