I recently purchased a new Husqvarna 372xp. I use Amsoil in a couple of our vehicles and am pleased with it. Does anyone have any experience using the Amsoil 2-cycle oil. It recommends a 100:1 ration rather than a 50:1 that is required with conventional 2-cycle oil and what is specified for the 372xp and most other chainsaws. They claim that 100:1 is what is needed with their oil. Does anyone have any experience using 100:1 Amsoil mix with their 372xp? Amsoil or not, running 100:1 in a new saw vs. the specified 50:1 makes me a little nervous. Thanks.

I run Amsoil on all my 2-strokes. Injector oil for the Polaris snowmobile (50:1 injected automatically). Saber Professional Outboard for my 90 Hp Merc (50:1) and 9.5 Hp Johnson kicker (50:1). I run Saber Professional in all my chainsaws at 40:1. They all get premium gas with no ethanol.

You see, 100:1 MIGHT be OK. I know some folks who have been running it at 100:1 in their various motors for years with no breakdowns. But I'm just a little leery of running it that lean.

BTW, you can do a search on here for Amsoil and you'll find enough reading to keep you busy for a LONG time. Pay no attention to the folks who will rip you for not using the search first. :biggrinbounce2:

I run either stihl ultra or saber pro in my saws. I run at 50:1 premium with 10% ethanol without any problems. Saber pro is less expensive than Ultra but it is also less convenient. I can buy saber at my local NAPA but it comes in quart bottles. Ultra comes in handy six-packs. I would stick with 50:1 and be sure to check your max rpms. I would run a new 372xp at 13 or 13.2 for the first 10 tanks and then crank it up to 13.5. Your dealer should do this for you. Good Luck
 
The problem with 100:1 mixes (or one of them at least) is that you're working with so little oil that you're very susceptible (or at least more so) to having problems related to incomplete mixing, etc.
 
Talk to Wild Knight and Erick. WN ran Amsoil in his 441 at 100:1 for a length of time. At tear down time, porting it, there was very little if any oil in the engine and there were obvious signs of excessive heat. He said, no more. Yeah, it'll probably get you by most of the time, but there appears to be no margin for error.
 
I'm sure that Amsoil is a great product, but I'm not running any oil at 100:1, if I were going to run it, my mix would be at least 50:1, it's a heck of a lot cheaper in the long run to make sure the saw is being lubed properly.

It really depends on how you are using your saw. Like in the recomendations from Amsoil states that an 80:1 ratio should be used for professional use.

Amsoil also stands behind their product, so if your saw is under warrenty and something should go wrong and the dealer has a fit about you using Amsoil at whatever mix ratio, Amsoil will take care of it. I had a warrenty issue like that with a sled a few years back and the dealer didn't want to fix it cuz of the Amsoil. Long story short he almost lost his dealership over it. There are Federal laws involved when it comes to warrenty.

I personally mix one jug of mix at 75:1 for all my 2-stroke equipment no matter what the "recomended" is. 75:1 is just easier for me, 2 oz per gal.

As a dealer I hear alot of questions like this so if you have any others just pm me or check out the Amsoil website.
 
I have been using/selling Amsoil for 18 years. Use Amsoil Sabre Professional for the small engines. That is the specific oil designed for them. You will be safe using it at 100:1. I did it for years. You can use it at whatever mix you want and be fine. I have used it at 100:1, 75:1 and 50:1. My 1997 Husky 257 is still a good saw and it spent most of its life on 100:1 and due to my ignorance, tuned too lean.

I notice no difference in the ratios. I am currently running it at 50:1 just because I choose to. There is not enough difference in expense to make the 100:1 necessary.

You will not be dissatisfied with the oil. Do a search here and you will find all kinds of stuff on it. Take the bad-mouthing with a grain of salt, as it usually comes from someone who has never tried it.
 
Shall I Syn?

I just bought a new Dolmar 420, and am thinking about running syn in it.

I was wondering though, if I should wait until it was broken in good, before using synthetic.
But then, some automobiles are run from the factory using syn.

What are your thoughts?

The consensus is synthetic from day one, pick your flavor. Everyone seems to like a different brand but synthetic seems to be the ticket. Then there is the mix ratio discussion, that one gets animated. Just ask

You don't need to break in 2-stroke motors with conventional oils. Go ahead with the Saber Professional right from the start if that's the oil you want. I'm a bit of a worrywort, so if I was going to eventually run a leaner mix, I'd run several tanks through it at 40:1 or 50:1 first.
 
The general consensus with vehicles is to run regular oil for awhile and break them in and then switch to synthetic. Vehicles break in slower on synthetic because the oil produces less heat/wear. I don't think that the new vehicles really have as much break-in as the older ones did.

I really don't know if that is the case with 2-strokes. I have always run a few tanks on my new saws with whatever the dealer gave me (just to get rid of it) and then I switched to Amsoil.

I don't think it would matter, but if you have the dealer's oil in it and it blows within a short time, then he can't point at the Amsoil and say, "That oil is the problem"-and some will do just that!
 
I was just going by what I've read & heard, that the power of a saw isn't fully realized until the saw is fully broken in.

As far as the ratio, I'm somewhat of a worrywort, too. :)
I'll run either 40:1 or 50:1 on all my 2-cycle equipment, just to be on the safe side.

:cheers:

:agree2:

That's a VERY good point.

I've heard stories about manufacturer's sometimes using any excuse to get out of paying.
 
I am sure that Amsoil make some excellent products, but don;t you think you'll always have a little doubt in your mind running 100:1? I would.

An there's no need... plenty of good synthetics to run at 50:1.

Don't know if you can get it out there, but I've been using Castrol Power 1 TTS.

I'm not pimping Amsoil, but the Saber Professional is one of them. I run it at 40:1 and 50:1 all the time, and it functions beautifully at that mix ratio. And you are right, quite a few excellent syn choices available. :) :)
 
Go over to the site, Bob's the Oil Guy, it's a forum dedicated to nothing but oil and related info, some people are oil junkies, like people are chainsaw addicts. There's more info there than most care to read.
 
Stihl Ultra, There are threads on this site that talk about how its the best oil on the planet.
