Custom/Hybrid Best oil for AM setup

Amsoil hp injector in everything, interceptor is better formulated for pv but I've never had any sort of issue with any amsoil product, anyone who blames engine problems on the oil their running more than likely did something else wrong to cause the problem. I'm running hp injector mixed 50:1 with vp110 in my non-pv 850
 
klots or amsoil (i run amsoil due to having run it forever) at 80:1. runs amazing and has sooooo much more power and lower cost than my old 50:1 mix.
 
100:1 here. 24 tanks Dasa 8mm. Changed out orings last week on head. Looks good still. Maybe time to check compression. After 10 minute run. Motor is 130, Head pipe 140, Exhaust 150. All low rpm stuff and the occasional blip off a wave.

40:1 holy rich. i switched away from 50:1 due to oil buildup on plugs and in my cases. but to each his own. this is why i usually dont post what i run.
 
Well no one has posted about putting various oils in water bottles with water and shaking them up to draw random conclusions...
What plugs are you guys running that 40:1 is fouling them out? And I think you want some oil on your power valves- they tend to slide better and wear less that way...

I don't run powervalves but I've been running 40:1 mixture with Royal Purple 2 stroke racing oil. I tried benol also but both fouled my plugs br8hs. One day I decided to try 50:1 with royal purple and whoala! Problem solved, didn't foul any plugs and had way better response! Klotz Benol still fouled my plugs yesterday at 50:1 So Maybe there is a different mixing ratio for that oil. (I'm using a easy mix bottle) I'm sticking to my 50:1 out of my little experience. (even though was recommended by everyone to use 40:1) Don't know if weather has anything to do with it but I live in warm climate and warm waters.
 
lol only time i run 40:1 is on dyno oil for break in..... my 750sx has run 5 years on just penzoil tcw3 outboard oil at 50:1 without a hiccup.... idk guess i was told way wrong when i started running skis.

have also heard that the royal purple likes a little more oil per gallon than some others. but it wasnt a super trust worthy source.

Just looked Yamaha recommends 50:1 from the factory. But yet a YZ125/250 call for 32:1.

Better to be on the safe side, I have never fouled plugs at 40:1 with amsoil, in bikes or skis. So if it aint causing a problem, why change it to have less protection?
 
MORE POWA!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

It would be safer to run stock exhaust and stock boost on ur diesel....... but u went and varried away from oem recommendation on that now didnt you

now your comparing the basic necessitates for a two stroke versus the control of my right foot lol

Its more important to match your jetting to your oil ratio, then your oil ratio in terms of power. Changing the oil ratio does affect the fuel/oil mix therefore affects the air to fuel mix as well. If you did no jetting changes and change you mixture then this is what happens in a very generic sense:

more oil= less fuel= more air ie leaner mixture= more power
less oil= more fuel= less air ie richer mixture= less power
____________________________________________________________________________________________________________
1. Factories determine things such as jetting, slide cutaway, and spark plug temperature based on a specific air/fuel ratio. If you put less oil in the gas (ie; 40:1, 50:1, 100:1) then the ratio is off and the mixture becomes richer. Cylinder temps go down, plugs start fouling, oil comes out of the pipes, etc..

2. An engine requires a specific amount of lubrication - the lower end bearings, rod bearings, wrist pin, and cylinder wall (just to name a few) have to rely solely on the tiny bit of oil you put in the gas. Less oil = more friction which = faster wear on these parts.

3. The oil in the fuel helps to seal the rings during compression. Too little oil, and the compression sufferes, leading to a loss of power.

4. Oil manufacturers add a detergent package to oil, and in most cases is is based on a 32:1 mix ratio. Any less or more oil, and the detergent package is no longer in spec - causing the oil to perform differently than it was designed to.

Many engineers spent considerable time and resources developing a proper premix ratio - if you follow it, you and your bike will be much happier!

There’s a myth that the less oil you use in your gas, the more horsepower you get.

Actually, you can get more horsepower out of a two-stroke engine with enough extra oil in the gas, because the oil provides a better ring seal and, therefore, more compression. People think that gas burns more efficiently with less oil, and therefore you get more performance. It almost makes sense if you look at that one statement alone.

The seal of the piston is critical. If you remove the lubricants from the gas, the viscosity of the mixture becomes lighter and more prone to vaporization. With a lean mixture, there is less oil to seal the rings. The sealing of the rings has more to do with the performance of the engine than the possibility of having better-burning gas with an ultra-lean gas/oil ratio.

Maybe if your BR8 plugs are fouling, you should try BR7s. That's the next hotter plug and may help burn that "excess" oil off. I've always had better experiences with BR7ES plugs than the factory recommended 8s...

I tried this.. but didn't go well.. I went from br8hs to br7hs but my heat sensor kicked in. Maybe if your in colder weather you might pull it off.
