Massive opportunity here for an aftermarket replacement oil pump - a proper one, like engines have been equipped with since engines were invented.

Our local Ford dealer has a couple of the 3.2 Wildtrax trucks, ex-demo with low mileage - but only 12 months warranty, now it's clear why!

By all accounts the other engine option, the 2.2 four banger is close on performance and a lot quieter, because the 3.2 is a noisy beast.

It's a variable rate oil pump i'll have you know, must save gallons of fuel over a week or two, apparently..:-)

Funny thing though, don't bog standard, old fashioned, luddite like, no trouble self priming, happy with any decent oil fitted by anyone in any time frame, oil pumps vary in the quantity and therefore pressure of oil they circulate as revs fluctuate, that's always been my experience when i've had oil pressure gauges and still is the case...wheel re-invented? lo and behold another wheel.

I'd guess that's what they're trying to avoid (that and discouraging DIY).

You probably don't need a lot of extra oil pressure at high revs (maybe a bit) and above the bypass valve pressure most of it 'll get bled off anyway.

An electric oil pump controlled by the ECU might do the job (don't some racers use them with a dry sump?) but the energy conversion losses might be too high. I'm assuming this is mechanical.

I don't class it in the same League of Uselessness as, say, the motor-driven fuel filler flap mentioned on here recently. (I had to laugh. I find I have to laugh a lot these days), since it probably does save some fuel.

I just don't think the gain, for me, would compensate for the increased hassle and fragility.Thats probably mostly because I run old vehicles, which of course is another thing they're trying to avoid.
