Definitely check out warranty as some seemingly innocuous jobs can cost mega bucks. 

 

I will do that. I was thinking about fitting lpg in Continental Europe but I am afraid of UK validation of LPG etc and  how insurence company will react.

Many cars works fine with LPG why should not Lexus, Imho Lexus is very reliable car in general so if LPG is done properly is should work well. I will definitely learn more about warranty before I go for it.

I take it that you haven't got an extended Lexus warranty on your car as no doubt fitting LPG to the car would invalidate it. 

You are certainly far braver than I am. 

My only experience with LPG was driving a late 90s Vauxhall Astra with a factory supplied conversion which wasn't a great success (overheating issues). 

Be interested to learn how it goes. 

Good Luck 

Well, I have but it runs out this year in summer,

I also found something like that " Converting a vehicle to run on Autogas may affect any warranty you have in place from the manufacturer, however this can often be supported by a new warranty offered by Liquid Gas UK Approved Autogas Installers and Accredited Distributors. "

I will have my service soon so I will ask my Toyota/Lexus dealer about warranty and LPG

then some more research in the subject after that depends how far I have to go for conversion will make final decision.

I am not really brave but I think there is a lot of myths about LPG 😄

This is correct. The NX300h does not have direct injection - that would be the 2AR-FSE engine which is used in the IS300h.

Thanks for replay. 

Thanks for your reply

I wouldn't even consider fitting lpg to a hybrid.

I believe hybrid does not change anything, you fit LPG to petrol engine not to the hybrid system

There are far too many issues that would concern me regarding reliability, especially travelling around Europe . If fuel economy is such an issue then perhaps you would be better off with a different vehicle as I don't know if the Atkinson cycle engines are suitable for conversion and if you were to get an issue when away from home who would have the knowledge to repair the car?

 

I had car with LPG system sometime ago and I had issue once, so LPG switch off it self and petrol was working as normal.

I don't know what you are getting mpg wise being in Scotland, but I understand from the service staff at my dealer and other owners the consumption on the NX is low 30s in normal use.

Mpg in Soctland is not really problem as I drive mostly around town, In summer I do like 8000+ miles cost cutting is like half when you have LPG (depends what type of lpg instalation you have)

If you are willing to sacrifice boot space for an lpg tank then clearly you don't need that much luggage room. I have had a UX as a loan car and fuel economy on that is really good with plenty of oomph. That engine is a new design.

I need boot space but I do not need spare wheel so the tank goes there like in most of LPG converted cars

Regarding LPG - if it could be done 1)What is the cost? 2)How much petrol would that cost buy you?

1. 1000-1300 in UK with all the warranty etc.
2. let say you use 10L per 100km so 1000L per 10000KM(at 130km/h - average max highway speed in europe)

For example Germany prices Min / Max
LPG    0.529 €/L    0.824 €/L
Unleaded    1.189 €/L    1.747 €/L
So we can easily say half (my previous car had very old LPG installation and I was averaging 45% cost cutting)

To move forward with my installation I need to find out what type injection my engine has
When I look for detail informations regarding NX300h engine they seems mixed with NX300 and NX200T
Also I would prefer liquid state injected LPG if possible.

Hello to everyone

I own Lexus NX300h (2015)

During the summer I travel a lot around the Europe (mostly motorways)

I love my car, and I do not want to change it yet but wanted to improve economy, so I was thinking about
LPG installation here goes the unknown

I asked few LPG dealers about NX300h and I am confused
Most of them says they do not convert direct injection engines
I thought that NX200T or NX300 are equipped direct injection engines not NX300h

I believe I have 2AR-FXE engine and I think this is port injection engin but want to know for sure.

Has anybody here converted Lexus NX300h to LPG in UK?

thanks.
