Jan the piston in a 706 up around the rings are .019 to .020 smaller then the skirt and with .004 to .0045 skirt to wall clearance when working one with the 87 octane she will swell that top over .025 and will seeze her . As the 87 is way to hot at peck comb. as it is a really hot burn where as the 93 is a longer cooler burn . Also the org. pistons that came in them new were a forged piston that would take the heat away from the top faster and transmit is to the skirt faster and could take the heat better . Now days all ya get is the cast piston. Plus nobody uses these old tractors for WORK we are all suppose to go out and buy brand new DIESEL TRACTORS that have computer control . Took me long time to figure out my heat problem on my OLD GAS combine as i was tryen to be CHEAP and run the CHEAP stuff in her . Coould not keep the engine temp down below 220 , tryed everything first had the radator cleaned out then recore it with a bigger rad with and extra row of tube changed the thermostat twice still no help checked timing nothing i did was helping . Till one day i was out at a sale in Indiania and on the way out gas prices were 35 cents a gallon less then at home and it was harvest time for corn , i got the bright idea to buy a couple tanks at the sale and fill them on the way home . Got the tanks bought and stopped at the fuel stop to fill the truck and the tanks , well they had a pump that said FARM GAS and the octane rating on it was 94 and it was twenty cents cheaper then the 87 at home well i filled both tanks on the truck bed that was 325 gallon . Come home and filled the old Massey 300 and went to shelling , The old Massey dropped engine temp down to 180-185 and stayed there ran better . Got me thinking and got to checking in books as to fuel requirements for this pice of equipment and oh what do i find that this old Massey needed the higher OCTANE as she was built when the gas was higher then i started READING on the requirements on the 706's and what do i find that they NEED 93 in them . I had never given it much thought as i was usen HIGH TEST in mine way before i READ it. and I DID do tillage with mine . The bad part is that when REALLY worken any of the 6 cylinder they all need the good stuff . Since the hightest of today is not even close to the reg. grade of days gone by. Yes i am and old foggy and i did grow up in the day of hot cars and fast wimmen and back in the day of the big gas powered semis that burnt 105 octane gas and that was back whenthe 460 -560's were new then along came the 06's and the gas was better then today, If ya think i am joken here go buy a car from back in the 60-first part of the seventys don't care if it is a big hp motor or a ma and pa grocery getter and put the new and improved gas of today in it and see what happens . I have been building engines since 1963 from mild to wild and i can look at a engine and tell ya the what and why's it did what it did .
