What oil is best? and what ratio?

[bwalker]

Yep sorry for the confusion. Mystic sea ans snow citgo aircooled and citgo sea and snow are all the same oil and im tickled pinkvwith the performance price and availability of that oil. My only complaint with saber pro is the tune got dulled and not as sharp and crisp at higher oil ratios like 32:1. It did well at 40 and 50:1 tho. The mystic is sharp at every ratio ive tried.

I ran cases of sea and snow through an 800cc rotax. The factory oil pump put out 20:1 or more and I never touched it. I was the only person I know that didnt have piston issues with that particular motor.

Looks like the new stuff, hope it's better than the previous oil.

It’s still just a synthetic blend. Wonder why they haven’t gone full synthetic yet.

What's different about it?

Semi synthetic or synthetic blends mean they are a mixture of synthetic and dyno oil. In general terms that means that the oil particle sizes can vary widely because synthetic particles are very small and uniform, and dyno particles can be small or large. The smaller and more uniform being better for getting in those tight spots. Meaning that even though it may have great detergents for cleaning it may not be much better lubricating as dyno oil.

Oh no I get that but what's the difference between the old and the new semi synthetic Husqvarna oil?

Gotcha no idea there lol. Just amazed that the one of the largest/the largest still uses semi synthetic lol

Could be same oil just new packaging graffics.

 

[tp2177]

I think @CoreyB has tried some and was thinking about breaking in his new ported 395xp in with it. Maybe he knows something about it?

Rubbish..

Rubbish..

Lol at least I know that's how it is on cars. Don't see the point in semi synthetic myself. Might as well just run dyno.

When I was racing in the Desert back in the '70s, I tried using Pennzoil two-stroke. It worked great, I expect that the latest version of mineral two-stroke oil is much better than that early stuff.

However, I felt it was a bit 'thin'. Just a feeling and I wanted more in the crankcase when I tore it down. I tried mixing one can of STP oil treatment with 3 quarts of Pennzoil. It ran the same, but the stuff was like grease all over the inside of the engine. I stuck with it for three years and never had a problem. I probably could have just run the Pennzoil, but I appreciated that 'greasy' covering whenever I tore the engine down. I expect the lower end bearings didn't object to it either.

If some of my saws are boat anchors that means I should run boat oil..right ?

 

[Keith Gandy]

Why do we contribute the cleanliness of an engine to the oil entirely? Could efree with no detergeants burn different then corn gas with detergeants and have a hand in carbon formation?

Good question Keith. Or VP canned Fuel.

I still say fuel is the reason some oils do what they do.

I've seen stihl ultra burn clean as hell and dirty as hell...why ?

 

[RI Chevy]

Also raises the question of octane too. Lower octane fuel burn cleaner or dirtier? Lots of unknowns.
Some oils burn better at lower octane? Or vice versa?

I know on ultra bottle it says to use at least 89 octane gas
