Gidday Fellas

thought I'd throw it out there.

While cruising along at 47mph (75kms) over a distance of 71.5 miles (115km) on relatively flat highway roads with the odd long incline here and there I used 19 litres of fuel.

Which calculated out to

16.5 Litres per 100 km
14.24 miles per gallon (U.S)
17.10 miles per gallon (imperial)

I suppose I could slow down a little and save a dollar but it seems to have a real sweet spot at 47mph so I can live with that.

Also my oil pressure gauge sits bang on 13psi for the first 30kms or so and then drops to 11psi for the remainder of the day.

BTW I do use a GPS attached to the windscreen for an actuate reading.

Anyway else have any figures to throw around??

I routinely get 18-20 mpg with my '28 Coupe in varying terrain. Drive it between 30 and 50+ mph. Have to slow down if leading a group of early '30s Chevys as their owners are reluctant to exceed ~ 40 mph. That is on recent VCCA tours. Recently lead a restored '53 on an ~ 20 mile stretch and he managed to keep up with the old '28. Has a rebuilt engine and carburetor. Timing a bit more advanced that recommended in the owners or repair manuals.

Oil pressure is ~ 2 psig at hot idle and less than 10 psig with 10W-30 oil.
