Just wondering how everyone goes having to put PULP into the DOHC 3.5. Can you run them on standard unleaded? What do you do on long country trips / Simpson crossings etc?
Currently looking at a 96 LWB with 143k on the clock for $16.5k. Seems a reasonable buy. Drivers legroom seems to be in short supply. Any fixes (apart from aftermarket seats) or did I just not get the seat positioning right?

PULP in DOHC 3.5
Moderator: -Scott-
Gday, You can use ULP or PULP. Sure it says to use PULP only, but our paj has never pinged whilst on ULP, im sure thats the case with many other DOHC owners also. On holidays or 4WD'ing it always gets PULP as its under more load, so pinging could occur in this case, + the extra oomph doesnt hurt. At the end of the day you get more kms out of PULP, so the cost equals out anyway...
As for the seats, well im 6'4" and I have plenty of room to move. Mind you the seats are pretty crap, no lumber adjustment and a bit too firm, for my likings.
PS Does anyone know if the DOHC has a knock sensor? If the answer is yes, then use whatever you want to, ECU will bring the timing back to run safely, but obviously sacrificing performance.

As fuel prices go up premium becomes more attractively priced.
At $1 a litre for regular, an extra 6c/litre for premium equals an extra 6% cost - you need a 6% (roughly) improvement in economy before it pays for itself.
At $1.35 a litre for regular (in Innamincka, for example
) an extra 6c/litre equals rouglhy 4.5% extra cost - so the premium fuel is more likely to pay for itself.
Sorry - I'm an engineer.

Emo,
I use PULP because $20.00 worth of it takes me further than $20.00 of ULP
I am 6"1' and found ,myself a bit too close to the steering wheel so I got out the grinder and the welder and modified the poition of the mounting holes in the seat to allow it to sit 40mm further back

I'm gonna stick my neck out and say if you dont use the recommended 92 octane you're asking for trouble. Even if you dont hear engine knock doesnt neccessarily mean detonation is NOT occuring in your cylinders and putting very harsh stress on critical parts.
Lower grade fuel just wasnt designed for a higher C/R engine like our 3.5's.
My 2cents.

Interesting. Is octane graded the same down there? I dont think you could get that kind of octane around here unless you went to a race shop 
Regular unleaded here is 87, mid-grade 89, and premium is usually 93, sometimes 92.
$2.22/us gal for 93 octane right now. It was $2.36 two weeks ago. 87 is less than $2 right now.

I met a bloke who does mobile fuel testing at service stations: drive in, take a litre from a few different pumps, and analyse for quality (using analysers distributed by my employer.) He said that Vortex claims 96 and is normally close to 97 Octane.
