gday prado boy.
this is just my opinion i may be right i may be wrong im sure ill hear about it.
if you any good quality oil change it every 5000ks and filter every 10000 its not going to make a difference.i have worked in a few mechanical places and each one says this is the best oil to use.so long as its clean really shouldnt matter.—~‘¬‘¥•s’B

Prado,

Have been using Rimula X for years, and have had no problems. Would agree with you that regular servicing probably counts more than the brand of oil. We also use the 5K/10K oil/filter regime.

We use the Rimula in everything from Cat grader, loader, landcruisers down to 9HP Kubota stationery engines.

Hooroo...

For the life of me i can't understand you people that change oil every 5000km but leave old filter in place. What a false economy that is. All that wonderfull new oil gets contaminated by the fine metal particles and other rubbish after 20km down the road. Let me see, you get 50.000 + car and can't afford new filter? That is the worst thing you can do to a motor,never mind the brand of oil you pour in it.
Good luck.

yep.
I've never done a change in the Patrol without doing a filter.

They're cheap as chips.

G'day,

as noted above, I go the oil and filter every 5000, buy the filters in bulk, gives you factory units cheap as the after market units and it keeps the 1HD-FT humming along...... every one will give you a different story, but the above method kept my old 2H running smoothly for many a hairy K and i am expecting the same with the new one.

cheers

Dazmit,

We bought a box of 10 oil filters, Toyo gave them to us for $32 each and the fuel filters, box of 10, $40 each, (that was a big price drop!!!, and we scedaddled pretty quick once we paid for those ones.....) so it's a bit of an up front cost, but we are now covered for the next couple of years and having no excuses to not do the oil and fuel ensures they are done like clockwork....... hey, i've nothing against the after market stuff, but I dont mind using the factory stuff if I can get it reasonably priced..... and I do so love the mighty 1HD-FT and want to look after it....

cheers

Prado boy Shell Rimula X is a very good oil in fact it is the premium shell diesel engine oil. When Shell brings out a new oil it retains the Rimula X name but is not the same as the previous Rimula X. Shell give the old oil a new name. In your case it wouldn't make any difference but Shell don't advise the use of Rimula X in old engines.
I don't believe you can put a fixed figure on oil changes as it is related to the type of driving, type of engine and type of oil Synthetic or Petrolum base. The indirect injection engines require more frequent oil changes than the direct injection engines.
Have a look a the following site, it is one person's gathering of information on oils and also includes links to some oil companies where synthetic oil properties are explained..

As they say oils aint oils sol.

I've used only Rimula X in my 1981 Peugeot diesel car since new, and after 260k kms it uses no more oil between changes than it did when new. Oil and filter changes have been at 5000kms.

To one and all,

Many thanx for your advice and opinions - I had no idea the topic would create so much interest! You have certainly changed my way of thinking about oil & filter changes. I will now be
buying filters in bulk
changing filters every 5000Km's (my Toyota dealer will receive a call tomorrow)
changing the oil every 10000Km's
and researching the site Meggs gave above (thanx heaps Meggs - much appreciated) to find the latest 'good oil' as they say.

Very much appreciated folks! Prado Boy

Clean oil is what it's all about...
you really should consider a bypass filter- both for less running costs (longer service intervals) AND longer engine life- IMHO.
I've been using them for 30 + years and the results are brilliant.

Prado,
This is I think is close to the most common questions asked on this Forum.
The service people will always be bias to the oil supplier (contract holder & you mentioned Shell....does change over time).
There are heaps of recommendations on the forum & past experiences.
I have had Diesels of my own for many years and as quoted by other responses --oil filters are cheap as chips.
At 5000K warm the engine, & replace both the sump oil & filter allowing time for the old oil to completely drain.
The enemy is soot in the oil which causes wear & it gets there in the same quantity regardless of mineral or synthetic base oils. Why keep some in a filter...chuck it away.
cheers mate.Get out there and use it.
Life is too short not to.
All the best...
Donald
