Title: Chainsaw Gas/Fuel
Post by: davbell22602 on December 07, 2012, 09:31:00 pm
I wanna where getting your gas from for your chainsaw? Gas pump? Premixed in a can?

I use the Tru Fuel that Dixie Sales sell. It has no ethenol and will stay fresh for 2 years. It comes in 40 or 50 to 1 mix ratios.

When I used to buy it at the pump it was regular gas. After 90 days I would have to dump it and mix fresh batch again. I would run into starting issues on my saws. I used the white bottle stihl mix and then switched to the 100:1 by amsoil before using Tru Fuel.

Amsoil at 100:1 is a no no.

Why is the Amsoil 100:1 a no no for? Its a synthetic oil mix.

But not at 100:1.

There's not enough oil there to cover the error margin. Amsoil has a lot of antiwear additives besides synthetic oil in the formula.

If you are a prolific chainsaw runner and you keep the bar buried all day, you will soon gall a piston. And the guy that tears the engine down will immediately see the lack of oil on the piston. I have a Dolmar here that a guy ran on Amway 100:1 and I have the galled piston and cylinder to prove what happens.

If you are compelled to use Amsoil, use it with a more realistic oil ratio like 50:1

I didnt know this about the amsoil oil mix. I quit using it anyways cause for some reason it doesnt work in lawnoby 2 cycle mowers. I have to use a mix I can use in everything 2 cycle from mowers to weedeaters to chainsaws. I dont use enough of the mix to keep a 2 gas cans mixed with 2 different ratios of mix. Thats why I use the 50:1 Tru fuel in the can.

I wish I could afford the trufuel 40:1.  I buy 5 gal at a time and go through it pretty quickly.  93 octane E-10 that usually has 12%-15%. So I use Klotz KL-200 which stays mixed with alcohol.  I cant find non ethanol gas from the local pumps.

Every customers saw gets dumped into glass jar to check their  fuel while working on it. I then fill with mine. Tune with mine at 32:1 and gives me a peace of mind it will be richer when they run their 50:1. 

Only had 1 saw so far that I had to re-tune that was running stihl dino 50:1 and it was just way to fat.

Is it just me, or do others think that of late it`s become a peeing contest as to who can use the LEAST amount of oil in the premix, in my fairly long motorcycle road racing[ 30+years] career a good part of that time with 2 strokes, the 3 different tuners of my bikes all said the same thing. More oil[within reason]= more power, to quote a point my RS125 Honda at 40-1 produced 44BHP at the rear wheel @ 12800rpm  At 30-1 it worked out @45.6BHP@ 13200rpm this was using Castrol A747 syn oil. Now I know we are talking different type engines [but they have the same basic operating system, requiring oil/fuel mix for lubrication] so in my opinion this holds good in all types of 2 stroke motors, surely saving a few pence/cents on less oil in each fuel mix is not worth losing the piece of mind + maybe the additional cost of piston & cylinder & possibly worse by going less on the lubrication I have chainsaws dating from 1967 /2006 & never run less than 32-1[ Stands back & awaits incoming]   ::)

Well I know new equipment such as chainsaws, weedeaters, etc. If the fuel mix ratio doesnt match the OEM ratio then it voids the warranty of it.

My new husqvarna blower said 50:1 but it has had a flavor of 32:1 since new.

 I dont care what the OEM or EPA says on running their 50:1.

JMO I think it is the same way with chainsaw motors. When I was racing them I was using 24:1

I`m some what con fused by this statement , should a small motor require warranty work & you return to point of purchase,  does the dealer , or does he/she have to send a sample of pre mix off to the manufacturer to get the oil content checked. I only ask as my local dealer [Husky & Oleo Mac] checks to see if there is oil in it, not how much, I know the only warranty he voids is if it`s straight gassed

I do my own stuff and don't want a dealer messing with it or trying to find fault or second guess with what I do.

If I were going to take a chainsaw to a dealer, I'd drain all the gas out of it!

I run 32:1 in everything.
