A little biased and premature...don't you think?

Only by experience.

That is kind of what I am starting to lean to as well. The wear metals are high but if you look at my very first report they were ultra low, like it hadnt even broken in at all.

The fuel dilution is a bit high but not as bad as I was thinking. It was literally -20/-30 for about 6 weeks straight. The poor truck did a lot of idling on that oil. Be curious to see what the next one is at.

Thanks Cord but I also agree with Snobdds, I don't have any drivability issues at all and besides a bit of carbon/soot nothing to cause me concerns. It is quite an efficient truck and has lots of jam.

Not really. My Mazda 3, with over 100k miles runs rich for the sake of keeping the catalytic converters at proper temperature. I'd like to see how much fuel economy and reduced fuel dilution you'd get if one of the tuners would adjust the fuel trim back to 14.5-7 range, instead of the 14.1-3 range we have now.

You also have to remember that i live in a place that looked like this pretty much every day for the whole life of this report:



It was especially cold/long this year. We usually get some decent variation in weather. Not this year. It is just starting to get nice here now. It has been terrible. Add that to extended use of winter gas, new truck breaking in, etc.

So the report said that there was a lot of fuel present in the oil. I didn't really think about it, but very valid point that the fuel reduced the viscosity of the oil. Probably a good idea to shorten the oil change intervals. I dumped my problem plagued Ecoboost, but have started doing oil changes every 5000K on my new truck. Cheap insurance

Everybody cringe!! I change oil and filter every 10k mi. At 112k mi I don't have to add and see no noticeable drop in oil level. Usually center between the marks. I think I've been using pennz 5-30 blend the past 5 or 6 changes but oil is oil I guess

Here's my report after 3600km, looks almost the same as yours Cosworth.
We had pretty much the same type of winter here too.
At 6400km I noticed the oil smelled like gas, so I took it into the dealer. They did the TSB on it which was a waste of time. If you don't have to do it, don't. My truck used to have all kinds of midrange power and now it doesn't, you have to rev the **** out of it to get it to go. I also lost some fuel milage using 87 octane, approximately 1.5L / 100km. Was averaging 14L/100km and after the TSB 15.5L/100km.
I have now switched to 91 octane and it's much better, averaging 13.5 so far. I only have one tank of 91 gas so far but we'll see if it stays like that.

So they changed the oil for me at 6400km but I wasn't able to get a sample. I still had a problem with the fuel/oil level at 7700km and they decided to change the HPFP and oil again. So I'll have to wait until 13000km to get the next sample done. So far seems the oil level is ok and there's no fuel smell in the oil.

And I forgot to mention I think the dealer is just using conventional oil.
I may change the oil sooner as I want synthetic in it for the summer.

That's great that we have someone to compare our reports to. I find it interesting that both of our trucks are quite similar. I wonder if this is actually normal break in. I remember reading that inside oil coolers are also some copper so as you break them in theoretically there would be some come out.

The more I look at these things the more I think this may be normal. I dont have any more gas in fuel than I remember my 5.4 having. Not saying you don't have these issues, but I think that until we get a large data sample (especially breaking in a vehicle in the cold sample) it may be pre-mature to freak just yet.

Just curious, what made you think the HPFP is an issue? What was your first clues? Just smell? I have a hard time getting a consistent oil level reading as it is.

The first thing the dealer checked for was leaky injectors and when they didn't find any then that was the only other part that would leak fuel directly into the engine. The only reason I found the rising oil level was because I changed the oil and knew where the oil level should have been as I park the truck in the same spot all the time. When the dealer changed the oil he told me he filled right to the full mark but when I got home and checked after letting it sit for a bit, it was a good 1/4" above full. So the oil levels are really hard to read on these engines depending on how the truck is sitting.
And yes I was a little freaked out too about the oil sample. If the oil rising comes back in the fall then I'll just change the it more often.
I would also like to know what your oil sample is next time you change it as I'll do the same. My next sample better have lower #'s.
