The Amsoil Saber at 100:1 caused a huge oil war on a chainsaw forum that I visit.  Most of the flaming came from people that didn't use it and had no basis of fact, and I felt the same way at first.  The thought of using only half of what most engine manufacturers require just doesn't make sense.......only after buying and using it did I understand that the oil is much more concentrated.

I originally bought it to use in my trials motorcycle.  When I was riding a 2 stroke trials bike in the woods I never got it opened up enough to clean out all the unburned oil, and it would start to drip unburned oil out the exhaust (spooge).  I was mixing at 80:1 with good synthetic oils which is the recommended ratio for a trials bike....but the woods riding prevented any fast riding.  Trials bikes don't run at speed much and if the oil mixture is too rich the unburned oil builds up in the crankcase - then when you crack the throttle to climb a hill the unburned oil can come up in a big burst......and the engine doesn't make good power when you need it most.

When I switched to the Amsoil Saber I ask the national importer and 5 time national trials champion about the Saber - and he said it was a great oil and they even ran it at 125:1 in a trials bike and it worked fine.  I did use the Amsoil Saber in my trials bike at 100:1 and it did cut down a bit on the smoke and drippy oil.

What I found out is the Saber Oil is much thicker than most 2 cycle oils, and it has less "solvent" in it and more oil......so the 100:1 mix ratio doesn't really mean much when comparing oils......only when measuring.  The oil is too thick to be used in injection systems - and it is only suitable for pre-mix.  I imagine that Amsoil would sell a lot more of it if they added some solvents and told you to mix it at 50:1 like other synthetic oils.......but they have other oils that fill that need.

After I sold my 2 stoke trials bike and bought a 4 stroke, I kept using the Saber in my yard equipment (leaf blower, weed wacker, tiller) and it works just fine.  I can't say that it works any better than the Maxima or Amsoil Eliminator that I mix at 50:1 for my chainsaws........but I have been using it since 2008 and everythng still runs fine.  If you buy a quality synthetic oil from Amsoil, Klotz, Maxima, etc.......you are likely to never have an oil problem if you mixture is right and your fuel is good.....and you don;t develop an air leak and run lean.  Most 2 stroke failures are not oil related - they are fuel/air mixture problems.      

 

Thanks for the input...I went ahead and ordered a quart of the saber 2-stroke oil...pretty pricey with shipping but it should get me through about 25 gals of premix which is way more than I'll ever ride my mopeds this summer...

I pronounce it,.. expensive...  ...

I moved this from the RSD to the Cafe.....it is not really a thread related to the Savage.

You comment about being expensive......a while back I did some math and I was surprised how expensive "2 stoke" pre-mix really is.

The Maxima K2 oil that I use in my chainsaw is $ 17.99 a litre....or $ 0.56 an ounce.

For a 50:1 fuel/oil ratio it takes 2.6 oz. of oil.....or $ 1.46 worth of oil.

For every gallon of 2 stroke mix you have $ 1.46 of oil and $ 3.70 worth of gasoline at this morning price.....or $ 5.16 a gallon.  
Cutting and burning wood for heat is still cheaper than buying propane however.

I have a Sea-Doo Challenger LE boat with a Rotax two-stroke engine. It specifies a special synthetic oil (NOT TC-W3). Last price check, last year, the oil cost over $50 per gallon. The boat uses an oil injection system, so I don't know the actual mix. Nor do I know of an equivalent oil. Best I can figure it costs me at least $2 per hour of engine operation, at light throttle.

The special oil is supposedly required to keep the variable exhaust "blades" from coking up and sticking. TC-W3 oils, it is claimed, will cause those exhaust "blades" to stick before too long.

Naturally enough, neither the requirement for nor the price of the oil was mentioned when I bought the boat.

I raced a Honda RS125......& a Suzuki RM125 super moto & a Kawasaki KX65......

Motul, Motul, Motul......

Price? Add race fuel at $125 for a 5 gal can!
