just breifly
For some strange reason (maybe wear or stretching of the timing belt or wear in the dizzy) a few degrees under or over may be the answer. Either take it to a good tune up place or experiment yourself I think
mine is optimal (performance and economy) at 12 or so degrees.(Dont quote me on this as its been a long time since I checked) ( A good
test or approx timing is that there should be a very noticable power band at around 4,000 rpm on.) should rev freely to 6000 rpm (further if you have extractors- if you dont have extractors - get them as you are driving it at about 75% of its potential suggest Genies ( a bit more expensive but more economical) as they have an excellent design for the patrol - helps pull gas away from the cylinders frees the motor up heaps. Properly tuned it should give 13lit/100 to 20lit/100 km highway to slow bush/hilly around town.
Treat it to some new plugs and leads and use a good high quality oil and air filter. Tyres around 34 front 36 rear for bitumen
then they are quite economical.

gday kezza.
i just fitted extractors to
mine a couple of weeks ago and boy huge change in economy.went from about 22lp100 no mater what i did on road /ofroad/towing ect to about 15lp100 highway 20 off road .
mine now revs freely from about 2500rpm in stead of about 3200rpm.
bit of a shame about the dizzy cutting out at 6200rpm.back bye popular

Hi Diamond -
Even though they are not supposed to, generally, a properly tuned set of extractors will improve the RB 30s low down grunt - dare I say - torque very markedly.
Bonz they are a very underrated motor by the public, an RB30 patrol will out accelerate most other 4bys off the mark for a short distance but obviously the lose the rev advantage over torque quite soon (unless you drive it like you hate it - which they dont seem to mind - being a very short stroked engine).
Run them on premium or throw in a dose of octane enhancer and you would swear you had a different donk in the thing.
They are great for being able to get out of trouble in mud sand and very steep slippery slopes because of the "instant " revs - as long as you are in the right gear.
