Anyone done LPG on S-Type R
Discussion
No matter where I look I cant get away from the fact, I want an S-Type R.
I've been running a 2.7D for thr past few months, after years away from jaguar's cant beleive how nice a car the s type still is now even though there 10+years old.
The only way I'm going to get the type R past Mrs TT is if it replace my motor bike
, and its got LPG to get over the horrendous mpg.
SO..... Has any one had LPG done on their S Type R, and how did it go?? I dont want to burn out the valves or melt the pistons or anything like that, which I understand were problem with early LPG kits and high performance engines.
Any comments welcomed.

I mentioned LPG to my local MOT garage and he said "Never seen one do more than 40,000 miles without needing new valves/seats"!
So I investigated on the web and apparently the newer systems now have an lubricator injector as well, so may overcome this?
But I did read somewhere that the Jaguar Supercharged Engine should not be LPG converted under any circumstance. Although that may have been for the older systems.
However, if someone has done it, I'd also like to hear about it.
Low throttle on LPG, switching back to petrol on higher throttle openings must be possible??

If it's on a car with soft valve seats, LPG will indeed speed up the onset of VSR. I don't believe the 4.2 V8 is particularly susceptible to this (although the 3.0 V6 is) but as mentioned above, a flashlube system would mitigate it anyway.
ETA: There are a few STRs that have been converted on jaguarforum.co.uk btw.

Done about 40000 miles on LPG with my X308 XJR.
Runs very nicely on LPG-only (e.g. no petrol after initial warm up) and only noticeable difference in performance is right at the top of the rev range, which as anyone who has driven a supercharged Jag will know, is rarely used in normal road driving. Can always switch back to petrol whenever one prefers.
Lose about 2 MPG, but fuel obviously fuel is much cheaper. I pay 70.5p/litre with Countrywide.
Conversion done by Steve Sparrow of Go LPG, who's workmanship has been excellent and has been very supportive since the conversion.
Steve says Flashlube not required on Jag V8 but is on V6.
