Block checked fine, crankshaft was ok......oil analysis showed fuel in the oil :/, next we sent injectors to get them checked....... but its funny cause when we drained the oil there was no gas smell :/

so the thought is that the oil was contaminated with fuel through the injectors and was not providing adequate protection?
that would have to be a lot of fuel contamination, considering fuel gets combusted in the chambers and exits through the exhaust.
i'm confused.

Someone mentioned having the new oil analysed, as maybe its counterfeit oil. Maybe he was on to something.
Maybe the oil isn't really oil, or at least not all oil, and contains something that the analysis assumed was fuel.
You are assuming that contaminant was introduced during running of the engine. What if it was there all along? What if the oil itself caused the problem?

Kinda reminds me... a LONG time ago ppl used to use "break-in" oil in newly rebuilt engines. I still use it on motorcycle engines. Can't be in for more than a few hundred miles. Dunno what would happen if you left it in for thousands of miles.

Fuel injectors are ok......
Oil analysis: Motul Xcess 8100 5w-40
Flashpoint ASTM D 93 (°C) - 108
ISO 3771 (mg KOH/g) - 9,23
Fosfor (P), (Ut.%) - 0,0873
Žveplo (S), (Ut.%) - 0,2521
Kalcij (Ca), (Ut.%) - 0,2605
Cink (Zn), (Ut.%) - 0,0981
Metal:
Chrome (Cr), (mg/kg) - 3
Copper (Cu), (mg/kg) - 14
Iron (Fe), (mg/kg) - 19
lead (Pb), (mg/kg) - <5
kositer (Sn) (mg/kg) - <14
Aluminij (Al), (mg/kg) - 16
Contaminants:
Silicij (Si), (mg/kg) - 55
They say they couldnt messure viscosity because there was so muc "fuel).....they asume that cause of low flashpoint
