Thread: D3 V8 LPG & TD high mileage ?

Don't be scared of high millage vehicles,high millage means lots of long runs which is good for a vehicle,I'd be more worried about a vehicle with bugger all k's from doing short school runs,308,000k's with correct servicing has lots of life left,500K is not unreasonable,auto's depends on if the fluid gets changed,all auto's need it done at least every 50K,people say 100K but they are wrong,don't forget there is plenty of L322 RR's about,a lot of vehicle for a bit more money. Pat

Thanks Pat,

Understand about the gearbox fluid change but wold like to know the life expectancy of a gearbox. With and without fluid changes.

The 308k's LPG raises life expectancy question with LPG fitted.

L322....no don't bring them up.....always wanted one of them.....but the D3 is more practical for my needs....have looked at the L322 thou...hmmm....any idea on fuel economy....no..no....must not ask!

I had an L322,if you can afford the coin,mmmmm.It's hard to say about how long things last,I've had three engines running LPG,all three ran better on gas than Petrol/diesel,not a worry IMHO,with the gearboxs plenty on here are getting miles up on them,hard worked with no services less then 100k,looked after they will last long enough to never worry about them,hard question to answer. Pat

Would like a L322...sat next to one in the carpark today.....

Think the D3 is the way to go for me.....

Thanks for your words Pat.

Hi Chilly,
This a very hard question to answer so many variables, it is only now LR are admitting that the gearbox oil isn't sealed for life. I suspect that if a vehicle has been properly serviced and maintained, fine however towing a 3.5 tonne van around and still being the same serviced vehicle I suspect that wear rates would be different.
Personally don't have any experience with gas and never will, not a great fan, heard a lot of horror stories which tend to outweigh the good ones. Saying that people usually come to a forum when they have a problem.......

I've heard all the horror stories,my 2.25 actually produced more power on gas than petrol,my 3.9 never ran as well on petrol as it did on gas,my Tdi is supposed to blow up,proven by a member on here in fact but 6 years later it's still going,LPG is like most things,buy the cheap conversions and have horror stories or pay up front and reek the benefits.

Hi Nomad9,

Not really that many variables. There must be an expected life expectancy of an engine and autobox. Yes other variables will effect that life but there has to be a standard expectation of a their life span.

Hi Pat,

I too have had LPG on an early V8 Disco 1. The old LPG system. Cannot say it went better on LPG but was reasonable on fuel economy. Sometimes,(whilst towing), it would do way more miles for the gas in the tank than it should do....bloody amazing really. So, not against an LPG vehicle. Loved that browser price!!

Hi Pat,
I bought a 3.9 with Petrol / gas, the reason I got the vehicle for the price I paid for it was it wasn't going. On investigation I found that there had been a back-fire in the intake system that had enough force to bend the air regulator valve, I suspect as you mention the system was a cheap one, not sure I never fitted it. I ripped al the gas system out, fitted a new air regulator and she ran as sweet as.
You mention cost, a lot of people I have spoken to bought gas to save money not to improve the performance, the improve in performance was an added bonus not the prime objective, if it happened.
Nowadays the payback on gas is a lot less than it used to be so the bias could possibly be to the cheaper system unless you planned to keep the vehicle for many years to reap the overall benefit.
One thing I don't like is that a gas engine runs hotter than a fuelled engine, in turn the cooling system has to work marginally harder, with power comes heat, it has to go somewhere.
The injection method I have heard is very important, into the inlet manifold or into the head, the closer to the cylinder the better.

I have not heard on many D3's on gas to be honest with the computer system and engine management system as it is you could well have to take the globe out of the check engine light. Dunno, no doubt somebody wil put me back on the straight and narrow.
