What oil is best? and what ratio?

[MustangMike]

several tanks of hp2 and Saber.

I like Saber at 40:1. Runs clean and lubricates well. Not saying it is the best, but there is nothing wrong with it either.

Old bottles of saber 100:1 used to say for racing or commercial applications run at richer mixtures. Can't remember but I thought it was up to 32:1

The blower works lightly, that's why this happens

If held wide open like it should be that’s a full load condition

The old 100:1 bottle stuff said up to 50:1 on the stuff I saw. Never seen any amsoil call for 32:1

Yes, but mixing the air is not difficult Maybe otherwise, the air does not reduce the rotational speed wot

I like the way Saber smells.... better than Ultra, HP2, VP, and Red Armor. Back in the 60's we had one of the first Mercury 100hp engines and that thing used a quart of "Formula 2" for every 6 gallons of Amoco white gas. That smell was fantastic! I remember smelling Ultra and having flashbacks to Formula 2.... made Ultra smell like a burning plastic fork.

Fan doesnt load the engine down enough so it doesn’t over rev and blow up? They designed this to be under this specific load and that’s enough to burn off the oil.
Take the fan off and run wide open and see how long it lasts. Shouldn’t soot up in one tank no matter what oil is used 50:1.

Not all chainsaws have an advance curve, older ones have set timing.

My Tomos770 (Husqv L77) has it.....with chinese chip between capacitor and distributor....

I'm just an ignorant consumer with 68 years under my belt. I ask you.... if octane does not prevent pre-ignition why does Valvoline say this?...

LOW-SPEED PRE-IGNITION PREVENTION​

While the causes of low-speed pre-ignition are not fully understood, there are a few critical steps one should take to prevent it from happening. That includes selecting high-quality engine oil, high-octane fuel, and cleaning products for a petrol system.

Low-Speed Pre-Ignition: What Is It And How To Prevent It - Valvoline™ Global KSA - EN

Poor lubricant selection leads to a wide range of engine performance issues. One of them is low-speed pre-ignition (LSPI). Also termed stochastic pre-ignition (SPI)...

Dont mix TGDi/GDi car engines with OPE....2 differeny worlds....

In (downsized) car engine....especially if equiped with turbo.... ACEA A3/B3 engine oils which are loaded with detergents (Calcium and Magnesium in oil lab tests)....especially Calcium Sulfonate contributes to LSPI phenomenom....

Thats why API SP.....ACEA C1/C2...vw508/509....MB226.?? etc engine oil standards for TGDi engines exist.....and they are usually low Calcium Sulphonate (and Magnesium Sulphonate).....

Redmax/Husky blower muffler on Red Armor. You can zoom in and see the muffler ia bone dry inside deapite having a large muffler mod..

Redmax kombi also ran on Red Armor.

I had the muffler off my 462 recently to hammer out a dent. Looks just fine to me after 2 seasons of 40:1 Red Armour. My 550xp looks about the same, and so does my 4-mix kombi powerhead.

That looks great!
