Major problem? No, just bad fuel

[California]

There are only a few diesel additives that I will use and have used with good results. Opti-Lube is a great lubricity additive, Hot Shot's EDT, Hot Shot's Winter Anti-Gel and Howes, which some people will have various things to say about. However I have used all of these additives for years and never had a fuel problem, unless I run out of fuel (most recent issue). I will say that Walmart's "Super Tech" Tc-w3 outboard 2 cycle oil is a great lubricity additive to use too, but not in any common rail engine, just in our older diesels.

I've used Power Service Silver Bottle in the two-cylinder YM240 for 20 years. The improved Cetane tames some of the harsh clank these have. Plus a little TC-W3 2 cycle oil if I find that free at HHW (described above). And the same fuel for the three cylinder YM186D, even though it normally runs smooth and doesn't need the Cetane improvement.

The bad diesel I drained recently had a witches brew of additives put in it over a couple of years, now that I think about it. Power Service, the Sta-Bil I described above, plus SeaFoam Injector Cleaner and some Peak Blue injector cleaner left over from long ago, all intended to fight the increasingly poor running. I think I overdid it. I noticed as I drained the fuel that it didn't smell like diesel at all. No wonder it wouldn't ignite.


Used ATF as fuel? No way, particulates could cause harmful damage. But I've read of people burning clean ATF and other low-viscosity lubricants - anything that will blend with diesel - in old simple diesels like mine. This 1970's design YM240 and it's marine-engine twin, were designed to run on whatever quality of diesel was found anywhere in the world. Its manual declares more frequent filter changes when the fuel has a tablespoon of water or debris per fillup.

Use Opti-lube XPD winter and summer. Half dose in summer for lubricity and full dose in colder months. Tractor never complains and never had jelled fuel.

All org. 012 Tach. Hrs. NTM. From the pump no additives or Mystery oil? 18 Yrs and I have never had it over 2200 RPMs with a 5' mower 90% of the hrs. I put on it. Once or twice to see how high full throttle was. Which was right at 2700 Eng. Rpms wide open I believe it's been so long. Pic. NTM. in 08 and just earlier this Yr.. Steve @ Spalding then would be proud of this one. Oil light still goes out in 5 Sec. cold start.
