Thread: V8 v diesel

Diesel isnt that expensive, you would think it was a million doillars a ltr the way you guys talk.

On a 730km run last weekend I used about 80ltrs (10.9ltrs/100kms) sitting on mainly 110kmh on the Hume in my lifted Disco with roofrack, 32" BFG All terrains and heaps of recovery gear, bullbar, winch, snorkle.

At 10.9 l/100kms it works out at $1.45 ltr for diesel at around 16c km which would be comparible if not better than most LPG systems and V8s.

On top of that, there are no plugs and leads, there is no electronics on a D1 like mine with 300Tdi where as the V8 has electric fuel pump, fuel injection and ignition computer etc etc.

Ive said before that it is comparable and that it is but I also liked the fact that after 730 kms I still have 1/4 of a tank (135ltr tank) so if I had to I could have driven to work all week and picked up the kids for xmas this arvo before having to fill up to go away tomorrow so the range is the best part.

Not much LPG in the middle of the bush or in the Simpson and thats why Ive got a Diesel.

that is one of the main reasons i wanted to change it ive had a couple of dare i say it toyota diesels and just easy to look after n maintain.and i'd love to do some big trips sumtime and the range ive got at moment just wont do and had some trouble gettin gas even on the bruce hwy to mackay.i just really love this truck its mint and what ive been chasin for a long time and dont wanna sell it just to get a diesel 1.

At 10.9 l/100kms it works out at $1.45 ltr for diesel at around 16c km which would be comparible if not better than most LPG systems and V8s.

BZZZZZZZTTTTT!

Works out about $0.12/km for me at the moment with LPG on a 3.9L V8. About $200 saving over 5000km.

BUT I do wish I had a diesel sometimes when I need the range. It doesn't happen all that often with the way we use ours at the moment - my daily transport when I need a car, weekend stuff, towing and trips around for a few days at a time.

Hey Addo110,
What type of box are you running. By the vintage you should have a 4 speed LT95. If so what transfer ratio does it have. Standard is about 1.112. You can change this to the diesel one 0.996. That will drop your revs by a few hundred RPM. I am sure that big V8 would handle the ratio change....Brian

just back from a small trip, i run 33" BFG AT, 2X spears, tent, 2 push bikes on the roof, 100Ltrs water, 125 Ltrs Diesel and all the **** SWMBO can load up.
Gased up at Saff bio diesel at 1.21 a ltr, toped off at the local Coles when we got back at 1.27 Ltr. worked out to be 11.2 ltrs per hundred.

thats a 3.9 NA isuzu with 4 speed. most driving was rather flat no real hills, we followed the coast line basicly

im running a r 380 not sure bout tranfer ratio as not sure what previous owner got it out of or if he got it new i'd think the latter as everything else is new.is it stamped anywhere i could have a look.

It will most likely be a LT230 transfer case. There are diesel ratios available for this box which will give you less rpm. I am surprised Trevor at landy spares Mackay didnt suggest this....Brian

i haven't really talked to him about it at this stage only had it in there once for tune up.but mite be sumthing i can look into had it done on my rangie and made sum difference just wanna get tacho 1st to see what revs im doin now...thanks brian
