[AT] Engine oil

[bradloomis at charter.net]

How hard is it to pull plugs and do a compression test? Not as cheap a repair as an oil change, but it may give you clues where the oil goes, in spite of no smoke. No mask needed for shop work at home. 😊

What this group needs (in my opinion) is a good farm equipment discussion.

Engine Oil--but wait, this isn't your ordinary oil discussion!!! 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

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.

 

What you guys think, worth a shot?
