My take on the oil, and I'm addressing Sythetic only, is that the syn oil
will not turn acidy like the dyno oil, so you can do like Ken says.
I do have my oild analized frequently to keep track of metel particulets
and specially the Dirt.
Having been in the Air Filter business for over 35 years have taught me
some major importance to the engine air filter.
If your not getting a good seal there, it is ammasing how much large
particulates manage to get through and coat the intake manifoil,intake
valve guides and cylinder walls and rings , act like sand paper. Oil
filters catch in my estamation only 30% of what is circulating .
There is a WIX sales rep coming over next week to pick up the carb fuel
filter to send back to their headqurters for evaluation of the plastic
valve that is set inside of the filter as it is being attacked by the
Ethanal.
What was interesting about the conversation was the percent of Ethnal he
wanted to know.
I am concluding that some things can deteriate if the concentration getss
higher.
