    This discussion has me worried that using Schaeffer synthenic 10w30 might not be adequate with propane in the big block Briggs?

    I wouldn't worry about the oil. I worked at a ice arena and the zamboni used regular napa oil. They had 2 with 305 chev engines one was 20 years old and ran 15 min max at a time, that is hard on a engine.

    remember the chevy has hydro lifters i think, your liquid cooled motors run constant temp air coolers are up and down in temp and there in 60-100+ degree days

    There are two things that make engine oil dirty: Dirt from the air, and combustion byproducts. With propane, there are no combustion byproducts.

    I just got a ferris is3100zp its made to run on propane. it uses a 32 briggs big block. It is saving me money down in central america cause gas is $12 and propane is $4. a gallon. The mower cuts fantastic ride is great and its really fast it has two 6 gallon tanks on it doesnt quite last all day. will buy 2 more tanks to take with it. I have a hustler z 60" with 27kohler. The ferris out works it and cuts super good in wet grass. I am getting another one this month. Oh I have a toyota v6 truck with over 230,000 miles on it that's been running on propane for its last 130,000 miles, this is the truck that pulls the mowers and work crew. No regulations down here, you can convert whatever you want and its on you. LOL.

    I've look into getting into propane but after talking with the service techs at the dealers. They say they about the same dB, same amount of power, they run cleaner, and they'll be more expensive to maintain since if they break, it's newer technology and it'll take the techs more time to fix, meaning higher maintenance bills. As for the cost of operating it he couldn't really tell me alot but from what I've read it'll be more expensive to run. Just remember it's "greener." and by greener I mean more green you wont have.

    I have talked to a rep and some owners on propane mowers and the owner says he is getting a $10.00 per day savings per mower on fuel. That would save us $300+ per week. As far as maintenance the only thing different is no carb, just the part to convert to propane which is minimal, everything else is the same as gas so repair cost should not change. We are going to demo one for a week and today is the first day. $300+ per week fuel savings plus the government kick back program makes it a no brainer for us.

    No fuel filter and no chance of grass or debris entering the tanks...
