economy of disco mpi's

<< < (4/4)

rangerider:
i have read elsewhere (parkers guide) that the economy difference between the V8 & the mpi was minimal, but glad to hear it confirmed. the v8 wont need to work anywhere near as hard as the mpi, so although using more fuel per rev of the engine, you dont need to rev anywhere near as hard to move along thus saving fuel there

Off road the standard engine lacks low down grunt, but get the cam shaft reprofiled for bottom end power and it will suprise you.  :D

i have to disagree as my mums had eaten 2 head gaskets in 3 weeks and has now dropped the bottom end, and is completly knackered, the mpg is about the same as my dads V8 and they only run out of petrol when i am driving it :oops:

Looks like you need a better mechanic, someone who knows how to work on the MPI engine, if you would like the engine manual let me know, as there is a simple mod that needs to be done with a head gasket change, or you will blow the gasket again, any decent mechanic should have known that, and I checked the mpg today this tank full worked out at 26.5 mpg :D
