Well try it today on this gas and see where your at , now i don't know what you call heavy work as your heavy work and mine may be two differant things and haulen the wife around in a cart may be heavy work for some as with most people of today just want a big toy to play with and a bigger sand box to play in but i am talken about doing a days work with one and myself i do not think that they are that hard on fuel if set correctly . Now if you are tryen to get the same power out of a lower grade fuel then yes it will use more if ya think i am kidding ya just go ahead and put one on a dyno and work her for her full rate and i am not talken about just running her up to see what it will do for peak power i am talken about maken hot water on the cooling system of the dyno at maxed out load and just see what happens on low grade gas . P/S hope ya got a big check book . After ya run the cheap stuff then run it on the high test and see what ya come up with do things like doing a EGT test keeping a close eye on water temp and you power and ofcourse the HP out put there is a differance . Like i have said i wished that i had the extra bucks to get one of them fancy digital camras and show ya the sleeves of some of the 460-560's and 706's that have tryed to use reg. unleaded gas and do real farm work . One 460 gasser that i just got done replacing the head gskt on will start to seeze while tryen to pull a full I H 560 manure spreader up a hill in 4th on 87 octain gas , Now put the 93 in it and it will run fine pullen 4x14 semi mount plows and the sleeves are all scored on it from the use of the 87 . Now i have check everything on that tractor and everything is as per the book other then the gas that is supplyed today and these problems all started in the last 10 years when they started screwen with the gas more then they did before . Now alot of this newer gas leans it's self out during combustion and when leaned out it get super hot and hear again the quality of the parts comes into play . When they were new they had Forged pistons from the factory and for a long time when ya rebuilt one the kits came with forged pistons , now today the kits ya get the pistons are CAST alu. Cast pistons can not get rid of the heat evenly and transfer the heat to the cylinder as fast and the biggest part of the heat is on the head of the piston and it swells and all of the damage occures above the top piston ring . Now they will get so hot so fast that you will never see it in the coolant temp as it take awhile to soak thru the head and upper part of the block into the water . How to cure this problem i do not have all the answers to this and calling Clevit or Seal Power and raisen holly hello falls on deaf ears from one person and i realy don't think they care as they have already got you money and if you want to get your toy back up and running again they are going to get more of it, Just like there junk head gskts that don't want to seal . They figure that if you can't go out and buy a new 100000 dollar tractor then you reealy should not be farmen and there parts that they are selling you are good enough for driven the tractors around at tractor showes as nobody that is a real farmer would ever even think of having and old tractor such as a gas burner around a farm to try and use everday. Now yes we have a few big boys over her that have the lastest and greatest but they did not make there money from from the farm , well maybe one did form selling out the guys that have had enough or got in to deep and the other daddy left them so much that they have to spend it But then there is the rest that are just scrapen by with old tired stuff that most guys restore for the showes . Lot more of the small guy just scrapen by over here then the big boy with deep pockets . So we have to make due and we see problems that most don't , and the advice that i give is as good as you boys are going to get from what we have learned the hard way.
