I just bought a 1998 4.5 GU that is dual fuel but I only run on LPG.

She has done a bit of work at 430,00kms but I have driven it around town for about 500kms over the last 2 weeks. It has also done a morning out at the tracks and it went fine.

I am thinking of doing a full service on it this weekend.

I plan to do the following:

- Oil and filter (I have have read changing it for 20W-50 every 5Ks is a good idea with an old, high millage engine)
- Spark plugs and leads
- Air filter
- Front Diff, Transfer Case, Gearbox (manual) and LSD oil change.

Any other suggestions would be great!
