Thread: Fuel consumption, a question most likely already asked.

thats about right, the effeciency of the series engines is down on lpg due to the basic nature of the engine namely that its low compression.

on petrol they can do 15l/100 but realistically expect 17/100 as a good figure 19-21/100 as about average.

In all of my driving a series 3 which was my everyday drive I averaged 17mpg overall - a little better on the highway - a little less around town. The Series 3 was replaced by a brand new 3.9V8 disco which overall gave the same fuel consumption.

Thanks guys I thought so but didn't want to believe it. It is a good thing it is so much fun to drive.

Does a Holden six fitted to one of these things do any better?

Regards

not really

Not significantly, although with changed gearing you might do a little better. Problem is that although higher compression, most Holden engines are significantly more powerful, so you drive faster!

The 2.25 petrol engine is designed for reliability, durability, driveability and use of low grade fuel. Note that economy did not get a mention! Add to this a totally unstreamlined shape, and a quite substantial mass, and fuel economy is not going to be good.

The economy device that was optional on 2a 88s is a heavy spring that comes into play at about half throttle. Either this or take note of the comments in the 2a owner's handbook "In common with all vehicles the petrol consumption mounts rapidly if high speeds are maintained. For example, at 50mph (80kph) the consumption in miles per gallon will be one and a half times as much as at 30mph (48kph) and at 70mph (112kph) the rate will be twice as much."

No - if anything worse because at cruising you are near its upper rev limit with landie gearing.

My 109 with a 186 on gas uses 26L/100km average with city, suburban and freeway driving on 7.5/16 tyres.
I keep telling my self that at the half price (13l/100km it is just as good as an average modern 4x4.

Wow - even my 101 does better than that on both gas and petrol.
