... very few modern engines with direct injection will get that sort of mileage because the heads get dirty too quickly and injectors take off the oil on the cylinder wall so the bores wear quicker than a non DI engine ...

The intake valves fouling is such a problem that automakers are gradually switching to dual injection, with both one direct in-chamber injector, and one "extra" port injector just for keeping the intake valves clean of crap:
The fuel wash in the cylinders and fuel contamination in the oil, courtesy of the much higher injector pressures in DI, exacerbate the problems with the very thin oils and very long oil change intervals so in vogue nowadays.
The long-term results are previsible ...

Damn mate, if only there was some quick and cheap way to deliver a car to the antipodes :banghead: . I just got another Z22SE Astra Coupe in very good condition with low mileage (54K km) for just 2K euros 🙂 .
