Thread: My12 Puma oil change every 5K or book 10k?

Isuzurover is the man regarding filtration....there may even be a donaldson/man hummel drop in replacement??

Funny thing about the LR owners hand book for my Tdi, it shows the service schedule, but has a different rate for extreme conditions....IMO some of LR items are running at extreme just in our summer heat. If it were me Id err on the side of caution and do them more regulary than 20k....plus remember that if your not doind alot of total Km's that time becomes a factor. It use to be that if you didnt do the Km's, you had to change the oil out before "X" time as it would break down???

another thing to consider is the gearbox and T/case...if the new gearbox is anything like the R380 in oil capacity I would not go past 20k for oil change. The lt230 is the same so same applies to it. These will both run HOT!


what about brakes?? it states in my handbook to REPLACE every rubber hose and seal in the brake system every 100k....does anyone do this?

Nissan, and I'm assuming the other manufacturers recommend the same, but no one does it.

Hoses do deteriorate and fail, I've seen a few and the local NRMA garage keeps a selection of common Holden/Ford/Toyota hoses on the wall.

Even stainless braided hose fails when it rubs on radius arms, or do I'm told

The Dealer told me it was every 20k before MY11, then they changed it back to every 10k for the MY11, and back to every 20k for MY12. Go figure???

Did the MY12 come with a larger sump capacity? If the dry fill of these engines is less than 9 litres, I struggle to comprehend how the oil service intervals can stretch 20,000 Kms. I don't care how good the oil chemistry is - My mind says "oil sludge".

The TD5 will do it piece of cake (depending on conditions) and our TD42T Patrol easy-peasy as it has a 10.5 litre sump.

A Tdi is maxed out @ 17,000km IME, 15000km is almost a stretch too far too.
Small engine, highly loaded and small sump capacity all contribute to this, and the above examples were 'old school' but best quality syn CI-4 oils.

Oil chemistry today is quite brilliant, the detergent/dispersant package has to be to cope with the EGR, etc.

I don't think they will become sludge monsters using 20,000km OCI's, but wear metals and soot will be higher than comfortable which has to impact on long term life.

At the end of the day the extended service intervals are to appeal to the bean counters when calculating running costs over a lease period

Isnt not only oil quality, but filtration has improver on these also???

Naa, the only car with a decent oil filter is the TD5. (oops, and the by-pass filter on some TD42Ts and 4BD1T's are ok too)

Full flow filters aren't really filters, more debris catchers IMO.
While the nano-fibre media Ben has spoken of is a major leap forward, AFAIK it hasn't filtered down to affordable, mass market filtration yet. Most full flow filter tech hasn't changed much over the last thirty to forty years. It's still cellulose fibre, etc. etc.

The Donaldson and Fleetguard syn fibre filters you and I use are a major step up from standard but they aren't in the hydraulic filter efficiency territory and soot doesn't even notice as it flows through.
Remember soot is micro particles of hard carbon, so impacts on wear metal numbers more than anything else, excluding dust/dirt, fuel and coolant leaks.

To do real extended oil changes you need a by-pass filter like the centrifuge in the TD5.
It actually pulls soot out of suspension.
