1) He personally would never contemplate using a Toyota common rail engine in areas of poor fuel quality, but he is a pretty cautious guy anyway...
That is what I was always lead to believe, and being in the developing world and buying a fair number of cruisers for fleet use I found it so:
- 79 and 78 series retaining 1HZ in Africa despite in Oz being released with the V8 d4d. Strangely this (essentially the same engine as the 200 series but minus a turbo) engine was released before the 200 series, which was rumoured to be delayed in release as Toyota had found issues with bad fuel in testing in Australia....
- Getting Prados with the 5L engine. But here I must point out that we bought them in EU from a dealer, and judging by the Arabic warning labels they were intended for another developing market.
So all this made sense - Toyo keeping old fashioned technology for markets where fuel quality is poor. But then they release the 200 series with D4D V8 officially in Ghana. I am very envious of a friend who has just got one - as a company car. Ridiculous (bearing in mind how much they cost!) but nice. So I am afraid that this seems that their policy of avoiding common rail in places like Africa is definately over. But to be honest as I have said before we have no single negative experience with electronics/new fangled injection types in VERY arduous use, and big global players would not be releasing products that are going to be potential disasters. If CAT and Toyota think common rail can be okay in such environments then I tend to think they may be right.
With regard to the extra filtration, any extra filtration is going to restrict flow. It is quite often that you will find people sticking in a small pusher pump (e.g. pacet or such) to help the the injection pump. We also do this on vehicles with sick pumps as it delays having to tear the pump down for a little while - i.e. you can start the damn thing! Separ make a very good filter with water trap, where you can choose the micron rating for the disposable element - we fitted them to MAN trucks and found them very durable if expensive.
As to the Prado, well I borrowed one as I was going on leave, meaning a good 8 hours behind the wheel on a variety of roads - good, bad and ugly. In the 3 liter form we got I found it VERY underpowered (a bit like the 105 series) but otherwise very good: comfortable, very sure footed/car like on good roads compared to 80/105/78 series, and fine on bad roads. In short I would be very happy to do a long trip in one. Much better stereo too! Obviously it is not a heavy duty vehicle in the sense of a 105 etc, but in reality unless the vehicle is going to do a lifetime of overlanding or work in forestry or mining then no problem. When we bought them we new it was a lighter vehicle, but better than paying $75,000 for a 200...
As I said I'm on leave, currently been enjoying a mini cooper s in Scotland and next week a Suzuki Jimny in rural Spain: should be interesting compared to big heavy stuff. Can't wait.
