What oil goes into a 1998 Holden Commodore?

Asked by Antonella

I have a 1998 Holden Commodore and I need to do a change of oil. I would like to know what type of oil does it take?

Assuming your car is a V6, I’d recommend a quality brand of oil with a viscosity of either 5W30 or 10W40. Provided you buy a quality, known brand, it will have all the additives that make modern multi-grade oils so much better than the oils that went before them. If your car runs on LPG (as many Commodores do) then you need to buy an oil that’s designed for use with this fuel. Fundamentally, though, the same rules apply: Stick to the correct grade and weight of oil and only use a quality brand, not the generic-branded supermarket stuff.

The actual oil capacity for a V6 Commodore of that vintage is 5.3 litres, so if you buy a six-litre pack, you’ll have enough for tops-ups between oil changes. Don’t forget to change the oil filter, too. While some mechanics reckon changing the filter every second oil change is enough, the wisdom of putting nice, clean oil through a dirty filter is beyond me, especially considering an oil filter costs only a few dollars.

Changing your engine’s oil is probably the best engine insurance you can buy. But you need to do it properly, so a workshop manual is probably a good thing to have as well as it should walk your through the process (important the first time). You also need to be able to dispose of the old oil and filter in an environmentally responsible way, too. But this is a great first maintenance job for the budding home mechanic and can really save you some money over the years. Good luck with it.
