Long story short, I have a fleet of old gas powered working FARM equipment--not talking about lawn equipment. We have always ran big name brand oil. I switched from Exxon Super HDII about 3-4 years ago because it was getting really hard to source. I switched over to Chevron Dello<o:p></o:p></p><p class=MsoPlainText>400 (both are 30W). The Dello is formulated for diesels, but supposedly works in older gas engines. I now have 2 engines that drink oil when being worked hard. My Farmall M can drop 2-3 qts in a couple hours of pulling a cultimulcher--yet you don't really notice it smoking. It does foul plugs. That work is a very heavy load. Also I have a 3300 Deere combine that will drop a qt or so every truckload of corn. Now I've only had this combine about 8 years and the oil consumption just started about 3 years ago--I swear some days it is worse than others. I really wonder if its the oil I'm using. I have on hand some CaseIH low-ash oil I run in lawnmowers--considering putting it in the combine for this fall. Supposedly the same stuff IH has been selling for 40+ years. The cost is about $3-4 more a quart, so an extra $25 to change oil. For the record, the rest of the gas powered fleet doesn't run hard/long enough to notice a problem. The combine is such a gas hog, can't help but wonder if its a fuel issue causing dilution.<o:p></o:p></p><p class=MsoPlainText><o:p> </o:p></p><p class=MsoPlainText>What you guys think, worth a shot?<o:p></o:p></p><p class=MsoPlainText><o:p> </o:p></p><p class=MsoPlainText>John Hall<o:p></o:p></p><p class=MsoPlainText><o:p> </o:p></p><p class=MsoPlainText><o:p> </o:p></p><p class=MsoPlainText>_______________________________________________<o:p></o:p></p><p class=MsoPlainText>AT mailing list<o:p></o:p></p><p class=MsoPlainText><a href="mailto:AT@lists.antique-tractor.com"><span style='color:windowtext;text-decoration:none'>AT@lists.antique-tractor.com</span></a><o:p></o:p></p><p class=MsoPlainText><a href="http://lists.antique-tractor.com/listinfo.cgi/at-antique-tractor.com"><span style='color:windowtext;text-decoration:none'>http://lists.antique-tractor.com/listinfo.cgi/at-antique-tractor.com</span></a><o:p></o:p></p></div></body></html>
