Synthetic 2 Stroke Oil Benefits? #4564866

I've been running synthetic 2 stroke oil ever since my local WM added their house brand to their shelves. It very well could be the placebo effect, but the engines seem to smoke much less? Engine performance seems to be about the same. I try to strictly run high octane fuel unless I'm in a pinch.

Anyone else notice this? What other benefits exist with synthetic 2 stroke oils?

less carbon depositing and less wear are probably the two biggest factors. some synthetics are able to run at higher ratios and still protect. higher film strength is important in 2 smokes..

Most important thing is heat. Synthetics can handle higher heat. Less stuck rings, etc.

No need to run high octane unless owners manual calls for it. Or unless you have turned up the timing laugh

My main reason is that it's E0.

I think it's more important to run a two stroke oil that was made for the intended purpose.
Running TCW3 in a weed eater although I am sure someone has been getting away with it for years produces hard carbon which sticks rings, blocks exhaust ports and causes issues.
Contrary to popular belief very high mix ratios ( less oil, more gas ) do not mean less carbon. I have always run rich ratios, 40:1 being the highest without carbon issues.
More oil produces more power and less wear. It's been documented. High ratios are no different than cafe standards.
They are the product of the EPA. Smoke doesn't bother me and I own and have always owned alot of two strokes with no issues but have seen the issues of TCW3 in ring sticking and carbon in non marine application.

It's not a matter of cost. It's a matter of most two cycle engines not designed to run on high octane fuel. Some engine manuals actually warn against using high octane fuel.

I've never used synthetic two cycle oil. I run conventional TC3 in air cooled engines and TCW3 in liquid cooled engines and I generally run more oil than recommended depending on which type of engine. Air cooled engines get 32-40:1 oil mix. My liquid cooled outboards are rated at 100:1 but I prefer to run about 70:1. No issues ever with either.

I agree regarding the high octane, especially in older 2 strokes. The problem lies in this - try to find E0 that isn't premium. Rarer than a hen's tooth in MN...

Please advise of any two cycle manufacturer that recommends high octane fuel.

Stihl does.

89 octane MINIMUM. I run 91 alky free in my Stihls.

Actually, I had a 1977 Evinrude 15 hp. Engines from that era were not designed to run on 92-93 octane. Go Google it.

You are right: synthetic definitely produces less smoke.

Echo, Stihl, Husqvarna and Poulan all recommend 89 Octane as a MINIMUM. The only other fuel related warnings they come with is not to use gas with more than 10% ethanol.

Also, If high octane fuel was bad for 2 strokes or other small engines, I guess Tru-Fuel and VP racing fuel pre-mixed fuels are really out to kill your engines. Most of them have a 94 Octane rating and come highly recommended for 2 stroke engines. Most of the major small engine manufacturers also contract Tru fuel and VP racing to make their brands of pre-mixed ready to use fuels with 92 or higher octane. Not designed to run on high octane huh?

For proof, here are some links. The octane rating is clearly shown towards the bottom of the can.

Both my Hitachi leaf blower (Tanaka engine) AND Echo SRM-266 weed eater require 89 octane or above. They both advise AGAINST using 87 octane.
