Good morning,

i bought a 1990 toyota corolla 1.8 diesel idi. It has 290,000 km. Perhaps an engine flush would loosen the crud and sludge in the engine and make better fuel mileage. I have been getting around 70 km/g around 44 mpg. I have heard about engine flush with automatic transmission fluid, kerosene, or diedel. I am a little apprehensive to flush such an old engine, because i have heard that the after engine flushes some old engines begin to leak and i would not like this.

Cheers

Jorge
