Does anyone out there use a synthetic oil in their Patrol 3.0lt TD.

If so, what is it and does this mean further between oil changes or is it still every 5000 K's

If you think it actually makes a difference too, please explain?

cheers

Hi Andrew, If you are looking at extending oil change intervals, why not look at a BY-PASS filter, filters down to 1 micron, I have been only changing the oil in my GU 4,2 td at 20, 000 km intervals since 100,000, the end of the warranty period, Now with 265, 000ks on the clock its still as good as ever. It also protects the Turbo with no solid particles entering the bearings. It will also save you money, save on oil, The original spin on filters dont clog as the particles are picked up by the BY-PASS filter, I change the BY-Pass filter every 2,500ks, it costs $5.00 and 700ml of oil top up. Change the spin ons at 20,000ks and the oil, the savings are huge. Also spend less time under the bonnet and more time using your vehicle. If you use a synthetic oil,the lubrication may be better but if you extend the oil change intervals, you are loading the oil with more abrasive carbon. Just a thought, Michael

Hi Michael, could you please post details, brand etc. of your bypass filter. I have '92 Mav td42 with DTS turbo and am wondering where possibly could another item fit under the bonnet ! Thanks Michael.

G'day Michael
What's the brand of bybass filter you are using, where did you get it and approx cost?
I'm very interested in extending my oil change interval. Currently using Motul synthetic, sent a 6000km sample off to the lab on friday.

Hi Michael & Goodsy, I have a unit from Filter Technology, they are based near Newcastle NSW. Rutherford i think is the place, It is the old Filter 2000 company, they were the original company that imported the american filter called Franz Filter.
I actually use a car size unit due to lack of space in my Patrol and just change it more often. The unit costs about $135 the filter is about $5, its like a toilet roll type and size. Loading the filter into the aluminium housing takes a bit of effort or for about $11 you can buy pre loaded filters, they are loaded into a tough plastic filter housing. The base housing is made of diecast aluminium, it's a very well made unit and compact. If you have heaps of room you can buy a bigger unit and change the filter less. Regards Michael

We use Mobil synthetic oil for oil our diesel vehicles including the tractors and farm equipment.
We use off-line filtering on all our equipment and change the oil every 12 months.
If the vehicles or equipment is not fitted with off-line filtering we fit it ourselves in the farm workshop. We change the main and off-line filters at 6 months.
We did use Mobil oil testing for 2 years but found the oil was more than capable going the 12 month changes.
My personal Pajero which does up to 50,000 k in 12 months gets changed at 30,000 k. My Pajero work is 70% highway 30% off-road

Thanks BJ

Just wondering, I suppose that's a mineral oil Valvoline your using????

What is its rating..ie 15W40 or ???

And 50,000km with no trouble?? from what i read on this forum about our 3.0 TD's, that's pretty good. I've done 23,000km's in mine with no real dramas, gets a bit depressing reading all the 'bad' stories.

Anyway, look forward to your reply.

cheers

our Navara 3.0 TD has 218,000 k on Mobil Synthetic and has had not had any problems.
Looking at the service record on the maintainence system says it has had 7 oil changes and 10 oil filter and off-line filter changes in that time.

We use the Baldwin off-line filter model B50
Baldwin Filters

and they can be purchased in Australia from
United Filters Aus

Have two diesels in the family, Both with bypass filters- a '91 TD 42 and a diesel Gemini- (1981) both owned since new and both never been touched as far as the engine is concerned.
I change the oil in the TD 42 about every 20,000klms - although oil analysis says I could go further, I do it that "often" for piece of mind.
The Gemini diesel has well over 300,000klms and has had about two or maybe three "oil changes" in it's life and the engine is as good as new- despite being thrashed in recent years by two sons learning to drive and subsequently driving it to uni etc.
However when the bypass element is changed you top up the oil so it gets a little bit of new oil regularly....
I would HIGHLY recommend a bypass filter before you worry too much about synthetics etc.... that can come later if you like.
