2 cycle in engine oil & fuel
About 14-15 yr ago I had an E. Texas parts store guy try to get me to add about 1 oz of 2cycle per qt of engine oil to crank at oil change for anti wear & lubricity. He also advocated adding it to fuel too for lubricity.
Being how he supposedly used to be a
"chemical engineer, or salesman, or something for an oil company", he swore & promised & crossed his heart & hoped to die & hock his first born if he was wrong. He told me about how everyone that
was in the know was doing it, gassers as well as diesel burners.
Well I, being the curious creature I am, grudgingly & cautiously added some,& headed back to Oregon with one of my 30,000# plus GVW loads.
About 2:00AM next morning N. of Amarillo in the middle of gizillion miles to nowhere, I'm grinding along, big fire built in that thing, turbo wound up, pyro bumping 1200+/-, watching gauges, both H2O gauges & both oil gauges OK, listening & smelling of everything etc.....& I think I start hearing something not right.
Well I find a "rest area" pullout with a fencepost for a port-a-*****, get pulled in there to ck things out. Every lifter was clicking & rattling, an injector miss every few seconds, that thing quivering & shuddering every 10-15 seconds.....and my imagination got to running wild. Now I'm sure rods fixing to fly out of it.....& I'm convinced the 2cycle oil did it all!!
After I managed to get that thing cooled down, oil & water checked, etc, it ran great & stout rest way to Oregon.
Short of the story & in hind sight, I think I just had my engine a bit too hot, oil getting too thin etc....hot enough for the fuel to "vaporlock", or something.
I was running 30 wt Shell Rimulla oil back then, which I used to run in my semi's.
I didn't run anymore 2cycle in the engine oil after that, but always kept the info in the back of my mind.
When I think back thru the years at all the
Hell & abuse I've given my engines, I'm convinced these IDI's gotta be tough!
As for as adding things to fuel, I'll add anything oily....ATF, WMO, oily floor sweep...anything that will manage to get thru my filters
But one thing I've figured out, with me running WVO in one tank & fuel in the other, if I add WMO to the fuel or to the WVO, it seems to clabber with the WVO & shorten the fuel filters life. ATF added doesn't seem to clabber.
I think I need to rig up separate fuel filters for each fuel tank, instead of running everything thru the same fuel filters....or don't burn WMO while I burn WVO.
Just thoughts along with my $.02....
