    ooohhh boy here we go again....

    I did 100 hour changes with synthetic, and I do 10K on my cars with synthetic. mobil 1 5/30 if the change happens in the winter 10/30 if it happens in summer.

    I still use dino oil and change it weekly which is about every 30 hrs. per machine. You can go longer between changes with syn. oil. I've only heard of high mileage truck or car motors having some problems when going from dino to syn.

    Synthetic is always better. If you are willing to change oil a half the recommended interval, dino would be almost just as good. Only use synthetic oil after the breakin. Do not use synthetic just to extend the oil change period. Don't extend past the recomended changing period no matter what. Do not listen to oil sale people's gimmic of extending changing period. Nothing beat changing oil more often.

    Most new small engine mfg. recommend synthetic, but they still keep the service intervals the same as dino.

    When I'm working, should it hang to the left, or should it hang to the right?

    I would say, if you're asking this question probably you should stick with dino.
    And consider perhaps one day switch to synthetic.
    Because why argue about it if the difference isn't understood?

    I run synth, and premium fuels, and double platinum plugs, but... Regular grease, the cheapest, 79 cents a big tube :laugh:
    So why argue about it?

    It takes way too long to outline here my exact cost / hour maintenance and parts over income-expense profit percent formulareas lol
    But that's what it boils down to, in my case, is cost, but long and short term, performance vs. down-time and all that crap is figured in.
    And that takes time, so just run dino until you see things different, best way I can say it, some folks dino forever, others synth, whatever.
