What oil is best? and what ratio?

The ignition of a car or a chainsaw is the same in that they bith have an advance curve. Wether it be mechanical(old cars) or electronic.

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

Yes but self advancing ignitions have been around a long time. One of stihls first was the 042/048 which came out early 70’s

No idea why the original and edited are showing

Im not sure why valvoline would say that. You will find much bad info on this subject on the internet. The refinery I work for even does this as well.
But that doesn't change the fact that Octane is a measure of a fuels resistance to Detonation and that pre ignition is a completely different phenomenon and the Valvoline article mentions this.
The recommendation for the use of high octane fuel in a GDI engin to help with pre ignition is probably with the though that if the engine is in slight detonation its also running hotter piston temps and that high octane fuel may qwell the detonation and lower pistons temps, which would make pre ignition less likely. This is fubar logic as modern engines, and a GDI is a modern engine, have knock sensors that detect detonation and dials ignition timing back accordingly. They also have EGR which lowers combustion chamber temps. Overall the article is just poorly written.

Okay thanks... so I have a question... back in 1972 or so I had a Suzuki TS250J dual sport single cylinder two stroke with oil injection. When I bought it the dealer sold me a quart of Castrol two stroke oil that was dark green in color and probably about the same viscosity as HP2. When I would cruise at a steady 55mph for a few miles the engine would make a loud clacking noise. I'd pull over and let the bike cool and all was fine. My buddy had a TS250J that would do the same thing on a different Castrol oil. We were told that mine was "vegetable" and his was "mineral". Not sure exactly what the "vegetable" was but it did not smell like castor. The clacking noise was definitely an attention grabber, and would only happen at a steady speed while cruising. I should have bypassed the injection and used pre-mix but wasn't sure how to do that. But... you got any idea what that clacking noise was? Anybody else?

No idea.

No idea.

Gee, I was hoping!

As you know, I modify saws, and the saws that show up here that have been ran on Red Armor are the worst ones to do muffler work on. Without exception, the mufflers are full of sticky goop that has to be boiled or burned out before we can be sure we have left no metal inside the muffler. On Stihl's two piece mufflers this isn't an issue, but on Husqvarna's closed mufflers it is a pain in the ass. I've learned to hate Red Armor just because of this.

Is it related to improper tune? Maybe so, but we see the same results on auto tune saws.

I've never run Red Armor before this week. I ran one tank 50:1 in my br800, checked the plug and it was black, checked the top of the piston and it looked like caramelized popcorn oil. One tank and I'm done. I immediately put in vp 40:1. I'll probably need to try some Quicksilver Power Tune to dissolve that crud. So many fans but not I.

I bought a cheap Parkside camera and now I can look into the cylinder

One tank of fuel you are joking right?

If the spark plug was black it needed to be tuned. Or it was still black from using Stihl ultra

Red armor was made buy spectrum division of Phillips 66 and I find it hard to believe it made everything black in one tank at normal ratios on a tuned machine. I’ve ran gallons of no smoke two stroke and never had an issue both prior to and after Phillips 66 bought spectrum. Was jasco fd rated and at the time about 20-22$ a gallon, few years after phillps buy out they quit making it. Was very clean oil and Phillips injex has always actually been pretty decent for a multi use 2 cycle thats fairly clean.

The Phillips injex TCW3 marine wasnt that great. The Injex Pro Low ash API TC product was pretty good, but not as good as FC or FD oils.

No, I checked before and after... the difference was profound. Black plug which was a nice tan.... piston crown had a lot of new crud.. It had it's chance to at least hold it's own, but it made a mess. My br800 and Red Armor don't do well together. No point in continuing to add carbon. It ran great, but at this time it is back on VP..... the first tank turned the plug tan again, but carbon still there, although less. And I'm not a VP fanboy, but it cleans well and runs great. Does VP lubricate well???? don't know, but it's thin, hence 40:1. In the market for the perfect oil.

The br800 has never run on Ultra. What little carbon that was in it before Red Armor was from several tanks of hp2 and Saber. It was very clean, but one tank of RA made a mess. Thing is, it was running great, like a match made in heaven. I thought about buying a gallon. Guess I'll wait... perhaps I'll try RA again and see what happens. The br800 is 10 months old.

I have never run red armor but I have only heard good things, maybe the only negative is that its high viscosity?

The blower works lightly, that's why this happens

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.
