Since I did the seafoam treatment two days ago, I notice my engine oil temperature runs slightly hotter than usual temperature (a half and three notches on the oil temperature gage). Is this normal (and it will go away after time) or am I looking at different potential problems?
The car has approximately 60000 miles. I did the seafoam treatment every 20000 miles.
Thank you for your help in advance, folks.

Did you put any seafoam in the oil?
Some recomend to do that and then change it right away.
If not, its not related.

I did the seafoam via the vacuum line, the good old fashion, then thick white smoke and so on.
Now I worry about the water pump.

Seafoam through the vac lines or the throttle body won't clean the carbon if that's what you were hoping for. the n54 is direct injected, being so, the seafoam will never even see the carbon. Seafoam was great for my Jeep, i swore by it, unfortunately in our cars through the vac lines or throttle body it doesn't see the carbon build up.

Lol it will see the carbon, although the effectiveness is questioned. Its when you put seafoam in the fuel tank that it will never see the intake valves. Through the throttle body or vacuum line is the only proper way to do it on the N54.

Seafoam will see the carbon buildup in our intake valves? Please explain, excuse my misunderstanding if this is the case.

Since our engines are direct injected, if seafoam is put in the fuel tank it will go directly into the cylinder and bypass the intake valves.

When seafoam is sucked into the vacuum port on the intake mani(or TB) it will mix with the air coming into the intake ports and coat the valves on the way into the cylinders.

..Thanks back to being on topic.. +111111 with replacing the oil soon after. I believe it changes the viscosity, therefore a change is necessary.

Maybe some of the seafoam got into the oil and cleaned the gunk off the oil temp sensor and now it's reading more accurately?

I always use this following guideline:

Is it possible to have seafoam get into the oil?
I've done the seafoam treatment several times and the oil temperature gage never deviated from the normal (2 notches before the the half on the normal operating temperature).
Any idea?

The seafoam isn't going to effect oil temps. If I read that correctly, you're oil temps are 35F higher than normal? That would put you at 270-280F, that is not good.

Right, it's unlikely to get it in the crankcase unless the ring seal is going bad, or you poured it in very quickly. It's more likely something else has changed oil temps or sensor reading. What were you trying to fix by doing the seafoam treatment?

[clairvoyant]

Yes, the oil temperature is around 270ish.
I have no oil cooler, everything is stock. Outside temperature is around 86 F. I just recently changed oil around last week. What would cause this issue?
I use the seafoam to "supposedly" clean the carbon built-up.
I don't think it's the seafoam treatment but what else out there?.

stay away from seafoam !!!
I'm sure My direct injectors were going bad befroe using seamfoam. Last week I filled up my tank and added seafoam. By the time my tank reached 3/4 My engine gave up !!! smoke come out of the muffler, engine wasn't going over 300-400 RPM and was shutting off. My car is at dealer now $1800 to change injectors and spark plugs

I may be wrong about seafoam but will NEVER use it. I think its intended for 60s 70s American cars...
