Thread: 3.9 V8 Fuel economy!?

I've been running my P38 for 15 years and never seen better than 21L per hundred K. Seen lots worse, when towing, like 24L per %

It pained me, but it was still less than the depreciation on a replacement so I just wore it.

When the engine died I was left with an excellent truck that I liked, in good condition but with no power source. Again, the depreciation on a replacement was a factor I could not ignore. So I spent up big on a stage 3 fully tuned engine that I imported from UK.

Now, I'm a lead foot. Can't help myself. So on my first country trip with the new engine I could not believe what I was seeing. After 21L per hundred, how does 12.3L per % sound to you? Around town I'm getting about 13.5L per % and it is not yet run in.

The car is transformed, - it is a rocket. Comparatively speaking that is, - it still is a heavy truck but it does the business in an amazing way. Would I do it again? You betcha. Is it worth the money? To me, yes, but only 'cos the old engine was cactus, and by replacing the engine with a fully engineered, tuned solution I knew what I was getting. Spending what a stage 3 tuned engine bored out to 5.4L costs is not a proposition unless you have little choice.

I would've got nothing for the car as it was, and buying a s/h replacement truck would not have known what problems I was buying.

that answers my question.
I looked at a 94 3.9 auto low kms the other day - extremely nice to drive and made me wonder if I could live with a V8 D1 vs a TDI D1 which I have had.
Well at 20l/100km....I would not be able to carry enough fuel to do some of the trips I at least want to have the option of doing.
So that is that..but soo nice.
If you are looking for a low k unmolested D1 auto - have a search on facebook markets, the car is in Melton and the guy selling is very keen to sell. Currently at 6500.
