Oil Analysis - First Time

[theswoleguy]

Gentlemen

Took a gamble and posted this here since, more of you guys are about go fast than regular maint and with my mods maybe you guys could say this is ok vs woah your stuff is broke.

Here is my first oil analysis done by Black Stone Labs. Please give feedback.

sounds like maybe you should change your oil a little more often, or find out why there is 7.5% fuel in the oil?

225 Injectors with 100% nozzles = hazing at idle plus a huge turbo and lag. Lots of fuel.

The level of copper bothers me. I'd pull the injectors and check the copper washers. If there all fine I'd be worried about bearings.

How do you like the 225/100? I think I'm going with the same injector size.

I would agree with Mitch. When I read fuel dilution and copper, I immediately thought of the copper washers for the injectors.

What causes this to happen? Injectors where done in June/july ish.

[Evil Eye]

A doubled up washer is the most likely since they sometimes don't come out with the injector. I wish you had an oil analysis from prior to the new injectors to compare against this one.

How or what causes them to come apart? Vibration tears them down? I'm use to regular inj just sitting into an intake manifold with a rubber seal. I know these are direct injection just curious as to how they get chewed up.

Could be a couple of things but the one the would seem the most likely is the mechanic didn't get all of the oil out of the cup before putting the injector in. That will end up giving invalid torque readings when you torque the injector down cuz the oil will only compress so far. Over time it will eventually bleed off leaving the injector loose and the pounding of the injector piston with all that pressure could be wearing the copper washer since copper is so soft. Just guessing here.
