Eibach make springs for other reputable aftermarket and factory fit tuning firms. They rarely offer more than 30mill drop for good reason. Overly harsh ride. Loss of suspension travel... And, it's too damn low. Bloody Chavs. ;) :D

I suspect a reply on every make going. What is required in said tyres? Grip? Mileage? Quiet? Midrange tyres Kumho ku31 fair grip level, stable, bit noisy. Falken912 below average grip, poor stability, very quiet, 452 slightly softer, still poor grip, below average miles. Both tramline like he'll, ime. Michelins, mega miles, mega bucks. Too hard generally. Dunlops, stable planted feal, sport max and ttexcellent grip. Noisy not cheap either. My personal choice sc3. Good grip v miles, reasonable noise, above average cost. Precise handling, IMO.

Pas pumps in my experience tend to fail at low rpm first. Does rpm affect it, ie is the steering heavier while manoeuvring/parking. Guessing not from your description. Not sure if IS has speed sensitive pas. If so It might be worth a diagnostic session to check electronic faults there. Other than that...I guess a failed steering component...top shock mount? Any knocks?

Our neighbour had the same thing happen. Iirc they where quoted £1500 by the dealer, but insurance covered the lot anyway. Not sure if they claimed on the house insurance or the car insurance though. I can't believe they touch the ecu, other than to re prog. the transponder codes.

What do you guys use for dtc's and diagnostics? Particularly interested in live data for fuel trims, lambda activity etc. Guessing dealers use Toyota based factory kit. Anyone know what its called? Is it available generally? (guessing not) If so what's the alternative? Would prefer something specific to the manufacturer, rather than generic. Although cost is a consideration too. Cheers

Lazdocker, thanks for your advice and efforts. That's good news. Koko, thankyou as well. Sounds like a 70 litre is possible. Should give reasonable range. :)

Guys...everyone has raised both pros and cons of running on LPG and we can all conclude it pays off if one will be doing a lot of miles and I mean a lot of miles..I mean Lazydocker was going through £150 a week so yes would really make sense and pay off quicky due to the miles being convered were as in my case I was going through £120 a month which confirms I wasnt covering that much miles for an LPG conversion to be viable so I guess if one goes through more than £100 a week then LPG would make sense but for someone like me going through £30 a week might aswell stick to petrol. so Chrigixer if your weekly expense is in the region of Lazydocker then I guess LPG will be the right way to go mate... I'm aware of the pros and cons of "LPG" what I am not aware of , obviously, is LPG on this particular model. Have you anything to add to that?...as the original question implies, I'm really looking for first hand factual experience. Thanks for your guess though. But as you say, the cost of the install, will take longer to return in fuel savings the less miles covered. Obviously, a fuel saving "formula" needs to be accurate when calculating this, or potentially for example a professional prins install costing in the region £2.500 will never return a saving at all if the car only covers 6000 miles a year and the owner sells it after two years. No brainer again. So, now you'll understand why DIY install offers further savings. Obviously. Payback in fuel savings will be achieved much sooner. Provided the install is not problematic of course. Hence my ORIGINAL QUESTION! Loooks like we all ending up at the same conclusion as I also mentioned in my prevoius post and i quote "LPG convertion does not always = saving money".....so like everyone one here is saying based on the miles one does LPG will be viable but for others it will be a waste of precious time/energy and some times money which in my case 3 years and an everage yearly miles of 8000 miles wasnt really worth the hassle but might certainly work for you Chrisgixer and thats also based on if the installation and flush and getting hold of live data goes to plan with no hicups We? Mate, please, give it a rest. Just try to be helpful thats all!! at the end of the day if i couldnt afford putting fuel in a 3.0 Lexus i wouldnt be buying one...and maybe still to a 1.4 focus Yeah, see, "we" still don't get it do "we". It's not a case of affording. If we couldnt afford an is300 and it's running costs we wouldn't have bought one in the first place. It's a case of not peshing money up the wall. If you want to waiste money unnecessarily that's up to yo of course. Just to explane the situation, and you'll notice this is the first time I have gone into detail on the vehicles use level, currently the car gets very little use. So although we intend to keep the car for several years, it's still arguable if its worth converting to dual fuel. However, a possible change in commuting circumstances may very well change all that. Hence, once again, the original question. And I quote; Anyone converted one of these to dual fuel? Nice deep wheel well. Can the valve seats take it? Now I realise your trying to be helpfull. But clearly, and I'll apologise in advance for this, you clearly have no clue on the subject what so ever. I'm afraid that's as polite a reply as i can manage given your input. Although I would like to thank those have given thier first hand experiences. :)

Rx is a v6. LS is a v8(?) Being honest, your right. I'd be better asking elsewhere. Thanks for your help

I reckon this is a wind up tbh.

There's little point conversing with an individual who refuses to see facts laid out before thier very eyes. Quite clearly, the picture posted by Koyo shows that the tank is set into the spare wheel well, and you must already know the boot floor can be raised as standard anyway. This is becoming rather ridiculous. You clearly have not one ounce of first hnad experience of LPG. IIl-inforemed nonsense.

Finally. Exactly right Koko. What on earth is he talking about..? Interested to know what size that tank is btw. Does it take advantage of the elevated boot floor?

Maybe I should try a more knowledgable section http://www.lexusownersclub.co.uk/forum/index.php?showtopic=76557&st=0 These guys clearly don't agree with you. And nor do I! If you had a more factually based opinion, then fair enough, but your opinion is based on nothing more than arrogance and bigotry afaict. Not one valid technical reason offered. No personal experience. Great, I'm sure the admins here are proud to have you. ;D

Thought not. (sigh...) Diagnostics needs to be live data capable btw. Long term fuel trims especially.

So I guess this has been running long enough for anyone with sound technical reasons why LPG shouldn't work on this engine to have said so by now. Nobody knows what diagnostics to use for the cars engine management, nobody knows what the inlet manifold us made of, nobody can offer a sound reason why their particular conversion miss behaved or what the problems/symptoms where...? Yet an over whelming proportion say, it doesn't work on this engine. Ok, your the experts here, fair enough. Now can anybody tell me why LPG doesn't work on this engine ?

I don't really think its up to us to bend over backwards to understand your point. If your point isn't clear, that's nobody else's fault but..... ...anyway. I'll take your command to keep you informed as I wish if that's ok. *****. Maybe some work on the manors front wouldn't go amiss? Hmm? And if I wanted a Diseasal it would have to be BMW, so there's two counts on why that's never ever going to happen.

An example based on what exactly? Imaginative accountancy at RBS? The equation you should be looking at relates to miles covered, gas price v petrol price, install price and pence per mile on gas v petrol. If the car covers 15000 miles a year, pay back on the install will be archived twice as quick as it would if it covered 7500 miles. Then your looking at pence per mile difference between gas and petrol, of which the saving is about 1/3 less than petrol. Yes there are cheaper ways of getting from A to B, but then we wouldn't all be driving Lexus in the first place would we. To me, driving on petrol is peshing money up the wall. Your choice though.

Too right, gas in not to be taken lightly. The guy I use is good. A bit off ish at first on my first install, but once he realised I wanted things right he was very helpfull and positive. Insurance is straightforward in theory but a lot of jobswoerths in call centres don't see dual fuel cars come up too often, so getting the right response can be difficult. Plus there's the change in criteria ie, no certificate as such, just a logged reg on the lpguk web site, ins can be a challenge to get cover in place. They do see sense in the end though.

The extra weight will depend on running with a completely full petrol tank as well, or not, but a good point. But as an estate will it note cope with that extra weight? However I'm not sure where your going with those figures? Time to payback on the install will depend on how many miles covered. The more miles your doing with general use the quicker payback will arrive, and the sooner we save money. Or, the sooner we stop giving money away to the tax man. Not sure I understand the negativity here. If the car doesn't cope well with autogas then fair enough, I can understand bad experiences. But there's seems to be something more to it? Reading between the lines...

... Is best for the is2/300 ? Need live data most importantly. Thanks.

Are you sure it is worth it? To fill up the boot, reduce performance a bit (inherent & unavoidable) and to have to drive at least 12000 miles on LPG alone to recover the costs (using Mr Rudus' figures) - probably including a fair few finding LPG stations. Add to this the real possibility of fitting a system you find causes problems or doesn't live up to expectation. Yep, all very fair points. Omega boot is massive, although the tank does block the though space on the saloon as the seats back drop down, rarely need this usefull feature though, so cheaper fuel takes priority. Sport cross estate has deep spare wheel well with the option to elevate the floor, so a large teroidal donut tank won't notice at all. Although a wheel bag for the spare isn't ideal, there's always the option to leave the spare at home if the full load space is needed, and risk a puncture. Finding gas stations gets easier as you get used to thier locations, but it's mostly a daily commute that I plan around, we don't usually fall short on holiday either. I'm more concerned that the Mrs can't re gas the omega tbh. It's big clunky filler system, her little hands don't have the strength, and she doesn't like the gas venting when remove the filler nozzle. (sigh...) This is a DIY project remember, and if an LPG manufacturer or installer can't set the system correctly, what does that tell you about the industry? I agree with your scepticism there, don't worry. Hence the DIY mentality on omegaowners. But until we have followed up on issues with LPG on this engine, we can't say where the fault lies....can we? (car,installer, kit,engine management) If I buy a kit, install it, bugger about setting up, decide your right and it's pants, take it off and sell It on for any other 6 cylinder engine what have I lost? A load of time for sure, a new inlet manifold, de solder the loom connections, fill in the wholes the wheel well with some gromits..... Anything else? ....must say Lexus seem far more reliable than omegas, I guess that means no DIY needed generally for you guys. That would make a pleasant change I must say.

Stag being very similar to that, if this engine is that fussy might look into prinz further though. But worth a price.

Stag300plus kit works well. Not top of the range at £700 odd quid in parts for the kit and tank, but it's good enough for omega engine management. Some fiddling is needed to tune nozel sizes to keep fuel trims in check and keep tick over steady, but once the correct size was established each install gave very consistent results. Needs a live data capable diagnostic tool to confirm fuel trims are within limits though. Does anyone here have one? Is it worth converting? Well, if it can be set up correctly then yes, there are savings to be had, and DIY keeps costs down and pay back can be had very quickly. Yes it depends on autogas suppliers location etc, and there are cheaper ways to drive. But the way I see it, it merely makes the car I want, and the way I want to drive it cheaper. We could all buy a diesel sh!t box front wheel drive bra burner, and save even more money. But I'd rather have a decent motor tbh, so that's diesels out IMO. On the omega, boot it on gas and change back to petrol at any revs and there's no extra take off or surge in power as petrol takes over. Yes gas is less powerfull, but it's really hard to tell. Can always set the parameters to switch back to petrol above, say, 4k rpm for those pesky BMW's if desired. The switch over is seamless though. Anyway, sounds like some further research is required. What do you guys do for code reading and diagnostics etc?
