It's very much a case of individual experience

Quote:
My personal experience of the 2.5NA is not favourable, whilst living in Wales my house mates had a 90 and a 110 both with 2.5NA engines and I found them gutless and asthmatic.

Comfortable cruising was down to around 50-55mph, as opposed to 60-65mph for the petrol and anything other than a mild incline waould reduce you to 1st and 2nd gear crawling compared to 3rd or 3rd OD in the petrol.


My experience is th opposite of that Crying or Very sad

A friend of mine had a 2.5D in quite average, almost poor, shape. It did Bedford to York and back on 1/4 tank with 2 on board plus a load of camping and other assorted gear. We think about 30 / gal. That was cruising at 60/70. Did slightly less mpg regularly

Another pal had a 90, granted it needed 4th for any hill and was poor in a headwind, it did return favourable mileage similar to David's above.

My 2.25P on the other hand is down to 3rd and often 2nd to pull up hills (on gas or petrol) and tops out at about 55. 60/65 on a good day(+tail wind etc!), but struggles to exceed 45 if the wind is gale force and in the wrong direction.

The 2.5D certainly ain't the most powerful, but in terms of a simplicity / reasonable return / power continuum it's not bad IMHO - and probably cheaper to run than my LPG that now returns only about 15mpg. And that's fully tuned, adjusted and sorted/serviced for gas.

On the holiday rally in Somerset last year, my 2.25 petrol behaved impeccably (better than it is now anyway). It would cruise up any of the hills in fourth quite happily (I was only down to 3rd if I was stuck behind granddad in his Honda Civic). On the motorway it would easily cruise at 70 (the overdrive helps with this though).

Fuel consumption, well we filled up at Sleaford, and then didn't have to fill up again until we were near Tetbury. Don't know how far this was cause the speedo is far from accurate Exclamation Embarassed

Does anybody have any ideas as to why this 2.25 might have decided to burn all its oil anyway? Its not something i've ever come across before. might it be rings, or a gasket? cracked block maybe?

Most burning of oil I've come across is down to valve stem seals or rings. Other causes poss, but these more common.

i must admit i am very tempted to put a 2.5NA in regardless, im just hoping for a bargin at Sodbury i think - nice 12J not requiring any major work i think.

It would be a lot easier to just take the head off and change oil stems - if thats what it is though thats the problem.
