Hi All Im after some opinions after being told by a agent selling Baldwin filters that by fitting a by-pass filter this will void my new car warranty. He also told me new cars are fitted with better filters these days so one is not needed. (B.S) I say. You would imagine you would have to gain some beneifit by fitting one and I do all my own services, except for the first one when the car is new. Just so I know the Job is done properly and not half done like every other nissan dealer seems to do these days. Plus I could always remove the filter if anything went wrong under warranty before Nissan cast there beady eyes over it.

Any Experiences welcomed

Cheer Steve

P.S Vehicle is a 2003 GU 4.2 TDI

I have the same Patrol with a little over 4000 klm.
Sounds close to what I'm getting. Towing a 4.5 X7
enclosed trailer up the stuart Hwy I got between
17 and 18 litres per hundred. without the trailer
getting about 13. So you are using a bit more then mine.
But I was hoping for better also.
Maybe when they are run in a bit more they will
deliver better economy. Can only hope.

I have a 2000 GU 4.2TD. (70,000km) Not EXACTLY the same, but close!
I get about 10l/100k at 90k/h, 11l/100k at 100k/h, 12.5l/100k at 110k/h.
This goes out to about 13.5l/100k at 90-100k/h when towing a TrakShak camper trailer (about 1000-1100kg).
All speeds and distances have been corrected (stock speedo/odometer is WAY out).
I'm pretty happy with those figures.
The whole lot (car/trailer/gear) is around the 4.5 tonne mark, so I really couldn't expect much better.

Cheers

Hi Steve,
Before I fitted my Frantz bi-pass filter to my Pajero diesel I contacted Mitsubishi Customer Service in Adelaide . They said No problem Go ahead

Steve.
What do you imagine a bypass filter will do that an in line filter will not? The reason that the oil has to be changed is the contamination caused by unburnt fuel diluting the oil, fitting a bypass filter will not change that so why bother? Eric.

Sorry Eric a little knowledge is a dangerous thing. You don't know what you are talking about... no offence intended.

Steve, though my current 4by is way out of warranty, when I fitted a bypass to my wife's Astra they confirmed in writing that no problem "provided you stay with manufacturers recommended oil change intervals"
Now it's just out of warranty (has always run on Mobil1), I will be getting oil analysis done and suspect from 30 odd years past experience with bypass filtering that with the combo of synthetic and bypass I'll probably be able to take it to 40,000 to 50,000 between complete changes. (Bear in mind it gets a slight change every time bypass filter is replaced.)
I do my GQ TD42 at about 20,000 klms - proven to be conservative with oil analysis.
Like I said you'll probably have to stick to recommended intervals till out of warranty
Cheers

G'day David, As you'd know (from recent postings), I've just fitted a Frantz to my GU 4.2... At the moment I'm a little "in the dark" re the procedure for getting oil analysis done.. Where do you take it/send it etc. ?? BTW I'm using Castrol GTD..
You may wish to email me direct at >

Ed,
BP did mine a few years ago, assume they still do but a quick phone call to Shell or BP would be able to answer the question.
I don't recall the exact price, but it wasn't what you'd call cheap,... but pays for itself because you then know how much you stretch out your changes with confidence. (I recall it costing about the same as an oil change ie: the cost of oil... not labour as I do it myself)
When I did it on myTD42 I could have in fact gone further but settled on 20k as a safe bet- it does depend on the type of driving you do.
Also, the people at Filter technology could answer the question for you.

Thanks David.. I'll "make some inquiries"..
In any case, 20K's is about what I had in mind for complete changes, your experience tends to confirm what i was thinking...
What about the spin-ons ?? How often do you change these?
(presumably, with no particles larger than 1/10 micron in the oil, they could last indefinitely, though I guess it would be prudent to change them occasionally)..
Much appreciate your input.. Ed. C.
