Fuel dilution thoughts.

[WeyounDS9]

Whats the thinking here on gettin rid of the fuel?

I run short trips (2 mile work commute). But the engine is a Nissan V8 and they are usually tight.
BUT its a DI and I understand that would make it more prone to fuel dilution?
I runs a Xw-40 always.

And every other day I drive 40 miles at 85-90 mph.
And once a week another trip for about an hour at around 100 mph (I am in Germany)

I figure this might evaporate the fuel out?

Thoughts?

some of the fuel will evaporate but not all.

when you check the oil level, do you smell fuel?

With your use case, and use of 40 weight oil, I wouldn't worry too much. That said, I wouldn't run 10,000 mile change intervals either.

You need to do oil analysis. Not guess.

But gas fuel dilution is significantly worse that diesel fuel dilution.

I agree. But you need to use the right lab, because I don't think all capture it correctly. Blackstone for example does not - or did not - perhaps someone has an update.

I checked the oil on my '01 7.3 and it was a tad bit overfull. I haven't checked it for awhile but don't remember it being that full. I heard Blackstone doesn't give the most accurate fuel readings. Who shall I go with to get the oil sampled? Thanks

NAPA is around $16 and does fuel dilution. And TBN.

I dont have access to NAPA or Blackstone since I am in Germany.
Oil has 4600 miles on it (RP 0w-40).

Smelled the oil today didnt smell particularily "gasoliny".
Just smelled like used motor oil.

That means either i do not suffer fuel dilution ,or yesterdays' 80 miles round trip on the autobahn evaporated it off.
Which I guess amounts to the same thing.

Yes wouldn't worry unless the fuel smell sticks out.

Don’t let your oil go more than 5000 miles on a change and you should be ok.
