Diesel Fuel In Motor Oil!

I know of a RB30DET that has been running mineral castrol GTX for the last 2 years and making 300+rwkw.

This was not in a high performance motor but it relates to engine flushes.

The motor was a NA RB30 and I used an off the shelf engine flush. You know, add, run for 10 minutes and dump.

Previously the motor had zero oil leaks for the past 6 months I had driven it. Decided to give it an engine flush and within 1 month it was leaking oil in numerous places.

I didnt link it to the flush but when I took it to get fixed I commented to the mechanic it was fine and then started leaking oil everywhere and I was still using the same oil. The first thing that was asked was if I had used an engine flush as he said it was a common occurence for this to happen on high milage engines. Supposedly, the oil leaks were technically already there but were being held closed by the sludge etc, the flush removed the sludge and hence it leaked oil.

Fact or fiction I dont know, but it made sense to me and I will never use one again.

I guess its like my first car. TE Cortina 250.

No oil leaks.. Washed the oil sludge off the side of the sump/motor and the think leaked like a siv.
