Do Not Sell My Personal Information Jump to content


Recommended Posts

My GS300 is running on LPg but getting some horrendous MPG. Im pretty sure most of it will be down to the fact that it'll be running on standard plugs.

Im looking at changing over to some LPG specific plugs but not sure where to get them or who does something decent.

Found a set on ebay and the guy is claiming they are good with LPG. According to their tests the plugs giving on average an extra 50 miles from 90 litres of LPG. They last about 10-12k and the brand is PSP, never have heard of them, anyone?

I also saw a link somewhere in here to some LPG plugs made by NGK if i remember correctly. Dont know the price of those but im guessing a fair bit dearer than these ones, but will probably offset that by their longer life or something.

But is there any one on here that uses specific plugs for LPG? And what can you say about them, good, bad, worse mistake ever made etc etc???

Cheers.

Your link does not work?? or is it just my pc.. But has far has i am aware their is no special Spark plugs that you would use just for LPG. your best bet is to speak to an LPG installer and he / she will tell you the plug have nothing to do with it.. But i might be corrected. Best to replace the plug with Denso Irridium plugs (i htink they are the same for the GD) mine is an IS200 on LPG.

I am planning to speak to a LPG service mechanic and i will ask him the same Q so i will Keep me posted.

The link does work on my PC, but if you have no luck then go on ebay and search this item number 160101599768 , Thats the LPG plugs.

I think you'll find LPG burns differently to normal petrol, as diesel does to petrol aswell. Working on that information it makes sense that a different spark plug should be required. If it was just a claim made on ebay i wouldnt have believed it but its also made by NGK, one of the worlds biggest spark plug manufacturers. My car doesnt run "rough" with the current plugs but it is WAY down on power when running on LPG and im not getting as much mileage from a tankful as i was hoping.

Im wanting to see a LPG installer myself but havnt had the time yet, but if you see one i would like to hear their opinion on it.

Just found this on www.spark-plugs.co.uk in the general FAQ area.

Q3. My vehicle has been modified to run LPG (liquid propane gas) or dual fuel, do I need to change my spark plugs to allow for this?

A3. Generally speaking no. Plugs may not last quite as long as with a standard petrol engine and the ignition system may have a harder time generating a spark. The denser charge in the combustion chamber means a higher voltage is required to jump the gap. For this reason it may help to reduce the spark plug gap by 0.2mm. If spark plugs become prone to overheating then it may be necessary to replace with plugs one grade colder.

Not too sure if i understand the answer correctly but it seems like in one bit they're saying they dont need to be changed, and then they're saying the current plugs and ignition system may be having a harder time so changing spark plugs may be a good idea. I think im abit confused by the answer really.
