New member posting first thread. Just purchased new Yellow ST-S and have 230 miles on it. Any opinions on engine break-in and use of synthetic oil. I use Amsoil in all my other vehicles including my last Spyder (2009 RS). I've read many different techniques for proper break-in and what oil to use and wondered how other Spyder owners felt. Is it better for your engine to use synthetic oil?

Chances are you have BRP synthetic blend in it now. Dump it out at 600 and continue with Amsoil. Thats what I did and continue to use it now with 26K on mine. As to breakin; with the milage you have on it now, I'd say its pretty much done so ride it like you would normally.

Just vary your rpms as much as you can for the break-in period and all will be fine! :2thumbs:

Here we go again! :D There are as many opinions on this subject as there are fish in the sea. I personally prefer to use the recommended oil (synthetic blend) for several thousand miles before I switch. That is less important with an engine with Nicasil cylinders like the Spyder, but I do believe the improved fuel mileage that comes toward the end of break-in occurs sooner with the blend. After that, Amsoil MC oil or another full synthetic with a JASO MA2 rating works well. I am not a proponent of the widely touted "break it in hard" procedures you read about. Today's precision machined engines, with hardened cylinders and moly rings, and motorcycle engines with roller and ball bearings instead of the plain bearings in automobiles, don't need to "wear in" like the old stuff, so they don't need hard or extensive break in procedures. Just obey the instructions in your manual and you will be fine...although thrashing the machine probably won't hurt. Just watch the heat and don't stay at one rpm for long stretches for the first 1,000 miles or so...and avoid the redline or lugging the engine (low rpm) for a while. JMHO

I thought Nakasil lined cylinders was a bad thing... sulfur in the fuel causes the lining to break down and once that happens cylinder wear occurs quickly, often spectacularly.

High quality fuels don't have much sulfur in them, but the US hardly has high quality fuels available everywhere. Good news is, the higher the octane rating the lower the sulfur.

No idea if this is still a problem. For that matter I have no idea if we have Nakasil lined cylinders :dontknow:

But it makes a good sales pitch for buying high octane fuels no?

Nikasil is a very hard compound, and has been used as a cylinder liner or coating for a long time in motorcycle engines, and more recently auto engines. Sulfur will degrade Nikasil, but the US really does not have enough sulfur in common pump swill to be a concern. Premium is no better or worse as far as sulfur goes, higher octane does not guarantee a lower ppm of sulfur. The good news for California folks, your boutique fuel has led the way, and has had lower sulfur counts for much longer than the rest of the lower 48.
"The federal gasoline sulfur regulation requires all refiners and importers of gasoline produced for use in the U.S. to produce low sulfur gasoline beginning in 2004. The regulation provides for a phase-in period in which refiners and importers must meet a 120 ppm average sulfur level in 2004, a 90 ppm average in 2005, and a 30 ppm average thereafter. There are also per-gallon "cap" limits to ensure that no gallon of gasoline will contain an unusally high sulfur content as a result of averaging. Many refiners will be producing gasoline with sulfur levels well below these limits. We believe that the federal low sulfur program will significantly reduce the average sulfur level in gasoline nationwide."
Thats a quote from Marilyn Bennett of the EPA.

a lot of good information but it all boils down to don't lug or maintain a constant rpm. Many want to get through the break in period quickly and get on a freeway and do 75 for hours. Vary your speeds, rpm's and gears and you will be fine..!! :ohyea:

Not much more to say on this one. Scotty has spoken. :thumbup:
