lpg how offen should I run on petrol

Being a 98 model I am guessing it the type which starts on petrol and changes over to lpg? if this is so then i don't think you need to. In any case once a week is ok. I try and drive home once a week on ulp and leave it overnight and then start up next morning on ulp before switching to gas. However i have been known to forget for a month or so lol.

thanks Brew,Istart it on petrol,and I well take your advice and once a month I well run it on ulp
regards uppy

fuel injected no! i would guess
carby models did to stop carby sticking..like our fairlane, which went up smoke due to stuck carby....

.needless to say my swmbo wont have a gas again...ang honest I didnt try anything..it didnt even enter my mind. lol

the Fairlane is efi,so hopefuly it doesnt happen to me
regards uppy

If your vehicle has a carby and you travel bumpy roads be aware that the carby float will not be floating (when useing gas), it will be sitting on the bottom of the chamber rubbing it's as... and over a long period may even wear a hole in the float. So.. it is possible that one day when you switch over to petrol the float may not float. I have seen a lot of wear on a float but have not actually heard of one getting a hole but worth having a look at occasionally.

As has already been said there is no reason to use petrol other then peace of mind to see that it will still work if you need it. Petrol does get 'stale' so it would not hurt to use a half tank and top up again every couple of months.

I always told people who came into work to do a tank every 4-6 weeks, but that was only if it started on lpg.

our 80 is on lpg and starts on petrol i think then switches over automatically i think some more!! so onyl do it if and when we are low on the lpg and need to use the gold!

Just had my Patrol converted to dual fuel.

Straight from the IMPCO handbook.

" Petrol Usage, the petrol tank on your vehicle should always be kept at least 1/4 full. Petrol does deteriorate over time , so it is recommended that you use approx 20l of petrol every 30-40 days."

Would seem from that , thats its more about not having stale fuel then any specific maintainence need.

Uppy,

I'm in habit of running it on petrol for 50kms or so everytime I fill up (LPG)

Never had a worry,

Run one tank of fuel through every month.

I had to replaced a customers injectors, fuel pump and flushed his tank out + 2 fuel filter replacements all because he only started his V6 Courier on fuel for 6 months. The injectors were uncleanable and the fuel pump could not build up pressure. The rust and crystal build up in the injector rails was very bad.

Total cost was $3500.00

Taxi's run all day and all night every day on just LPG, my old man's ford falcon cab clocked up 950000 kms in the time he owned it and he bought it second hand, it never missed a beat. He has a new cab now another Falcon, but he still drives the old cab around as it's his daily driver and I have borrowed it on occasion. I asked him if I had to run the old girl on unleaded he strongly advised not to as he had never done so. Before I forget it's fuel injected no carby, has the flash lube set up etc.
I hope this little ditty helps regards, Smitty.

Look in the engine bay, if you see a bottle with a line coming out of the top of it and going to the manifold (depending on what injector system you have, throttle body etc) thats your flash lube bottle. Very good prevents valve stem seals/valve seats from drying up/cracking/wearing out and valves from overheating. Also prevents crystal like scale deposits in the injectors. That is the reason others run petrol fuel on occasion, but with the flash lube set up (depending on the year/make/model of the vehicle) there is not really a need to chop change from gas to petrol. As the engine should be tuned to run on gas if it has it fitted, you will find if you swich over to petrol the engine will run like a dog.
Use Flashlube Valve Saver Fluid, Australias No.1 selling Lead Replacement Additive. I got this speal from the flash lube site:
With specially developed upper cylinder lubricants and cleaners most of the foregoing problems are reduced or eliminated. It cleans and controls valve seat deposits, resulting in better valve cooling through the valve seats and reduces exhaust valve overheating due to leakage of hot exhaust gases. The risk of valve sticking is reduced - also a major cause of valve and valve seat burning.
Flashlube Valve Saver Fluid is not an ordinary upper cylinder lubricant/cleaner. It is the first upper cylinder lubricant cleaner in Australia containing a lead substitute, greatly reducing valve seat recession and providing all the lubrication qualities of leaded petrol.

I gotta go, as I am hunting down a MGB tailshaft or repaired as I damaged mine yesterday. See ya.

I decided to have a new one made as it was $175.00 cheeper than to buy one new from the parts deeler in Sydney.
Cheers, Smitty.
