I was reading on another forum where some guys was running the Amsoil 100:1 in his engine and was having problems. He was not comfortable with a 100:1 mix and wanted somethhing richer, like a 50:1. Is there any reason that he could not mix the Amsoil at 50:1 instead of 100:1? The thread seemed to imply that the Amsoil is usable at 100:1 only, and he needed to set some other oil (M1) to mix richer. Huh?
Amsoil 100:1 question

I use Amsoil professional Saber at 32 to 1 exclusively in all my two cycle engines and it seems to work well. I use it in sthil chain saws, Echo tillers, and hedge trimmers, Shindaiwa string trimmers, and stick edgers, and backpack blowers with no problems so far. I see the Amsoil 100 to 1 ads and I'm not understanding why anyone would want to use a mix THAT LEAN
, IMHO oil is you two-cycle engines friend and no one could beat me hard enough or long enough to make me mix at even 50 to 1. My engines don't noticably smoke after warm up with my 32 to 1 ratio, never have fouled a plug and have never needed to clean any carbon out of any engine I have run it in. I'm happy and 4 oz of oil isn't very much when compared with a gallon (128 oz.)of premium fuel. I think the whole 50 to 1 ratio is so that the engines can pass EPA standards, and if anything it has forced the oil makers and engine makers to develop better oils and engines so they can comply.
I also run it at about 40:1 in my chainsaw and weedwacker. 100:1 is just stupid. Even if it does provide enough protection when the engine is running, it doesn't leave enough oil on the internal parts to stop rust! I do use it at 100:1 in my lawnmower...but it's a 4 cycle!
I have run Amsoil 100:1 oil at 80:1 for five years with no problems at all in the lawn and garden equip. Used at 100:1 in the boat (1994 48SPL Evinrude outboard). Emgines still have good compression. However, with all the opinions I have read here I just started to use the Amsoil (the new stuff they have out I think called Sabre) at 2 ounces per gallon, which is 60 something to 1 ratio. Amsoil states on the bottle a mixture as rich as 50:1 can be used in extreme conditions, but from my experience I believe anything richer than 50:1 is a waste of money.

I agree to a certain extent, but carbon deposits are the 2 stroke cycle emgine's worst enemy and I think anything richer than 50:1 is probably too much and may possibly create carbon deposits over a period of time.
Did anyone even look at the Amsoil website?
They state something like-
80:1 is recommended for "severe" conditions.
IMO, a chain saw is "severe". Other 2 strokers (weed whackers, leaf blowers, etc.) are not so severe, IMO.
I have run it for the last 4-5 years anywhere from 100:1 – 60:1. My normal mix is 1.5 oz/gal which works out to be 85:1. I run it in a Stilh chainsaw, Homelite blower, and line trimmer, and a Yamaha 50 hp. outboard (now I use the saber outboard). I’ve had zero problems, and on those motors I can inspect through the exhaust port, they are very clean. I really don’t understand what the problem is. People have been using this stuff for a very long time, and I’ve yet to see any real problems. In my mind it’s a little bit like the 3000 OCI myth. It can seem like a leap of faith to try it. FWIW, I also like the Mobil 1 MT2X too. I don’t like the Redline Allsport however.

1 oz./gal is 128:1 ratio.
Thanks Ray. I meant 1.5 oz. I corrected my previous post. Need more coffee!
FWIW my Tohatsu outboard owners manual says it can be run at up to 100:1 on a daily basis, but prior to any period of non use it should be run at 50:1. It's a little 5hp putt putt so the ratios reflect the rpm. Wouldn't think of running my saw at those ratios, but the idea of storage residual oil still applys.
Not sure if there is any truth to it but I read somewhere years ago that a two cycle oil should comprise of both light oil and heavy oils. The idea was the light oils separate off fast and get to the topend, the heavys "stick" around a little longer in the crankcase. I've always wondered if those 100:1 oils have any light oils? or make a compromise and are all medium oils? there just doesn't seem to be enough volume to have both? Looking at msds sheets it does seem most two cycle oils do have both light and heavys.

The thing is, there are no UOA's for two cycles. You can't tell really how well it's working until you tear the engine apart. I could give you straight gasoline and tell you it's got Amsoil in it, and you'd say it's working great, for 5 minutes or so. At 100:1 I'm sure Amsoil works or they wouldn't advertise it like that, but it might only be as good as mixing straight 30 oil. Nobody knows unless they do a very expensive experiment involving the teardown of several engines...

MSsparks, do you have a clue what you are talking about? Reccomending a tcw3/boat oil like amsoil HP for a aircooled power equipment is assinine. It not only does not the warranty requirments of ANY piece of OPE it will lead to serious deposit issues over time.
Also Wanna bet that a 32:1 mix doesnt burn hotter?
BTW No one will warranty your equipment when ran at a higher ration than the OEM suggests.

Amsoil 100:1 contains very little solvents this is one reason it takes less oil to get a mix ratio.
If you are running that rich I would recommend that you run the HP injector synthetic it is 30% cheaper by the quart as well. You will have just as much success if not more running the HP injector at those lean mix ratios. You can use the HP injector up to 50:1.
Just my opinion!!
BTW the 100:1 has been test at 300:1 and still protects.
For weedeater and other lawn care equipment, the biggest problem is carbon loading and exhaust clogging.
Most weedeats are never run at full speed for any lenght of time, most are either just off idle or 1/2 power at most, this is even being used in lawn care buisness (I know I used to work in it) I wish I would have known about Amsoil then, we had a lot of trouble with the 2 cycles getting clogged and producing a lot of smoke. The 100:1 would have cured this and probably made our equipment last longer.
BTW, most equipment mixed at the 100:1 will run cooler than those mixed at 32:1 they will produce more power and you can run a lower octance fuel too.
Many more benifits.

I not going to argue, But I double checked with Amsoil the HPI would be perfectly fine for someone who wants to run a leaner mix ratio.
All I can say is to call up Amsoil and order a G-1474. It's the Series 2000 2cycle video. This will show you that running leaner mix ratios gives more power and produces less heat.
I don't sell Amsoil so I have nothing to gain by saying this, But Amsoil has been the best 2 stroke oil I have used by far. When I remove the muffler from my Lawn-Boy mower, I can see the cylinder wall by looking down the exhaust port. There is no scoring or scuffing on the five year old Lawn-Boy mower that has run on Amsoil all its life at 80:1. I now use it at 2 ounces per gallon (about 65:1) because you all have me paranoid
about the lean mix ratios.
