The "TRACTOR DOCTOR" wrote a real good article in Red Power Magazine about six months ago explaining how IH Low Ash oil prevents valve burning.  In his article he was working on a 16 HP Kohler engine in a Cub Cadet but the cause is the same.  As oil gets into the valve guide to lube the exh valve stem & valve guide, the high temps burn the oil and cause a hard black carbon deposit on the inside of the valve guide and on the outside of the valve stem. Eventually the valve looses all it's clearance and when the valve gets hot and expands the valve sticks in the guide, doesn't seat completely, the head of the valve can't cool and the valve burns.

 

The "FIX" for the Kohler was to remove the head, then eh valve, scrap the carbon depostits off, decarbon the head, replace head with new head gasket, change oil to IH Low Ash oil and run.  On a 6-cyl gas engine in a 460, 560, 706 the repair would be a little more involved, and expensive.

Ran IH Low Ash in our 464G for the 1st 4000 hours.  Did a head at 4100 or so....blew gasket.  Valves looked fine.  Have used 15/40 for about 700 hours doing light stuff.  She started using oil now.  For fun got a pail of straight 30wt Conoco oil.  Fixed the blowby. Now for another 4000!


What, there is another color tractor besides red? Your kidding! I got a 1066, 186 (16k orig hrs), MX170, 8930+, 7140, 464 G, 684, C50, 585, 544E, 60xt, 135 McCormick, ok and a little orange scraping tractor. And we use all of them on the dairy.

I must have been doing something wrong then! Super M ran on mostly agway 30 wt oil back on the farm. Served it well! I used a 1650 cub cadet with a 16 horse kohler as my commercial mower for many years with no burnt valves or carbon. We had a deere 214, 14 horse kohler we would use as a brush hog on a neighboring farm for many years with no ill effects on the valves. My opinion is todays oil is better than yesterdays oil, plus gasoline additives have varied greatly over the years, heck forget oil burning valves, what is ethanol going to do to these engines now? Gasoline plays a larger part in this equasion than oil does!

 

Also I believe detergent oils are quite similar to high ash oil! High ash leaves buildup and detergent oils would be similar since they absorb dirt particles, non detergent and low ash keep carbon and such from building up! What do I know?

IMO today's oils should be able to prevent build up better than older oil formulas. If you have carbon build up issues or are worried about it then try switching to sythetic and/or flushing the oil system might be worth while.

I use name brand (Shell Rotella) 15w-40 in all 27 IH tractors, diesel and gas and have for many years. Sometimes it is a little too viscous for our New York State winters. Ken Ryan

15w40 Cenpeco in all the Diesel stuff, dad uses it in his gassers too.  I feel it is a little heavy in cold weather so I use about 6qts of 15w40 and about 3 qts of 5w30 in my 656 gas.

IH a brand you can count on!
