    I was thinking about going to 20-50 wt. syn. in my 17 Springfield for summer. It gets hot,95+ (May thru oct) most of my ride time in the summer. I change oil @ 3500. I would go back to the recommended 20-40 in the fall. Just figured I would hear if there is any pro or con to this Idea? Thanks for any input on this. sorry for the double post of the vanishing side covers, new to this posting stuff.

    This has been discussed exhaustingly, here. EVERYONE has an opinion and they range from oil weight variance being blasphemy to others claiming that the 20W-40 formulation is has more to do with creating a profit center than properly caring for your engine. We've chatted about 20W-40 contributing to the TS-111 "heavy" first shift idiosyncrasy and we've had a research paper invoking flame war about the quantifiable value of genuine dinosaur blood versus synthetic oils and what the proper formulation of the former might be. I encourage you to read through those oil threads [to include the "This is not an oil thread", oil thread] and make your own decision.
    As for me, I look to @Lake City Larry as the archetype of how to get the most out of this motorcycle. His experience and mileage is only exceeded by the sheer diversity of opinion and amount of misinformation available on the internet.

    Been running the Indian oil kit from day one. South Florida heat has not been an issue for me. 50k miles and all is well.

    I am not an expert on the subject matter, but my opinion is this. I think it is more important to get the right oil specs (the oil is in the transmission, clutch and motor, in my Scout) in the oil than what the weight numbers are, meaning the 40 versus 50....

    Oh, and do some research.....

    It is your motorcycle engine, you run what makes you sleep better at night.
