Is anyone here running/familiar with autogas? My 1976 4x4 F250 is a 351c petrol/gasoline engine. Its had a conversion done so it runs duel fuel, petrol/gasoline and autogas/propane.
I quite enjoy having the gas on board, it adds to my fuel storage, plus it cuts down on cost. Accounting for currency and volumetric conversions, "gasoline" prices where I live are roughly $6.40 a gallon, as opposed to autogas which is roughly $3.90 a gallon. I don't get nearly the same amount of power per volumetric measure of autogas as I do with petrol, but my "back of the envelope" calculations suggest that there's a definite economical benefit to using the autogas.
Is anyone else familiar with autogas? I'm having a slight issue at the moment where I feel like the engine is struggling a little, like its misfiring when I put it under load, or try to take off in second gear. I remember a mechanic telling me once when I was still a kid with an autogas car, and knew nothing about working on cars, that autogas is harder to ignite than petrol, so any issues with your ignition system are likely to be noticed earlier when you have autogas. I remember him saying it was one thing in particular - I just cant remember what it was. Obviously its either distributor, leads, or spark plugs, I just can't remember which. Does anyone here know?
Also, while I'm on the topic, has anyone ever water-proofed a "gasoline" vehicle? I want to be able to cross the same rivers, etc... that the diesel vehicles do. I usually just coat the distributor with WD-40 and hope for the best, but, I've heard of people sealing the distributor with silicone and installing a high-mount breather tube. Does anyone here have any experience/resources with this.
Thanks guys, sorry for all the questions. Hope someone can help out.
