how often do you have to run a tank of unleaded thru a lpg motor

[mattyr82]

got a vz wagon on dual fuel,it has the injected system as is all you can get on the alloytec. on these systems it is computer controlled to start on petrol and automatically change to l.p.g when the car has reached the right temp.
just wondering if anyone knows if it is benificial to run a tank of unleaded thru it say every 3 or 4 tanks of l.p.g.
also whats the go with flash lube, what is it and should i be using it.
what are your thoughts?

always a good idea to run the petrol side of it now and then , i tell my customers to run on petrol aleast once aweek to and from work , if doing a trip a say Melb to to Sydney run for aleast 100kms up and 100 kms back , Injected system starting and running on petrol until warmed is great removes alot of the headaches for cold start and driving on gas for alot of systems , Recommendations for most cars is to run aleast 30 liters of fuel per month , roughly 300kms per month on petrol .

Once a week is fine. Please note that gas injection systems will depend on a properly functioning petrol system so it is vital that you keep the petrol side of things in tip-top condition. Premium unleaded fuel is highly recommended.
