661 Oil Test 32:1 vs 40:1 vs 50:1 ?

I was gifted some oils to try.

Interesting.......

Blendzall is extremely dirty and keep an eye on it it likes to seperate very fast.

I was told it would separate at 35F.

My BIL ran a stock 1988 Banshee on Opti2 @ 100:1. He ran it HARD on the dunes at Silver Lake, circle track racing on the farm, high speed country roads, etc. He gave it no mercy. I didn't replace the crank until maybe 5 years ago. He got >20 years out of the original crank. Blows my mind how he got away with it though. I tried to talk him into something else and he figures why mess with what works.

I never had an issue with 927 in my built Banshee, even below freezing. I always made sure to shake it good before use and added 1oz of isopropyl alcohol per gallon when it was cold. It's a minor issue IMHO, that's easily handled.

Not from a viscosity standpoint. What I am saying is the viscosity of the mix doesn't matter because mix isn't what lubes the engine. .

It is mix that is metered, so a more viscous oil could allow more fuel to be metered through the carb

I have seen it seperate after a few days in the summer.

Volume of each oil would be the same though, so viscosity alone doesn't effect tuning. A higher viscosity oils inability to combust properly is another story.

Going to try running the Amsoil Saber at 40:1 for a while and see how clean the saw stays .
I think if oil is slobbering out the muffler it's a bit much . I'll see and maybe adjust to 45:1 as well .

Just ordered 5 gal. bucket of Super m for 180. Should last the summer + between bikes and saws

Banshee top end is fresh 1 tank thru it so will tear it down at the end of the season see how it looks.

RedBull, are you still planning to test some additional oils, particularly another high viscosity oil?

right now my list to test includes -

2r
lucas
710
possibly belray si7
800 off road
possibly r50 - the viscosity is too high IMO and I'm guessing it wouldn't be good in winter. So checking with them to see how low of temp in winter we can use it.
H1R - redo with reset.

for sure in the 661. don't have a lot of motivation to do the 660. It takes a lot of time to do things the way I do em. Plus that is approx 3-4 new chains per oil. Plus I gotta find the logs and prep em. So like I said...not a lot of motivations to do the 660 or really anything else.

927 is only about 20% castor IIRC. Blendzall is 100%. Once it seperate shaking may or may not remix it.
Maxima doesn't reccomend running 927 below 40 degrees I believe.
927 or super techniplate aren't so bad in non powervalves motors if you load them very hard, and jet them spot on.

50-70% per MSDS.

I used R50 in the low teens without issue. It does get thick in the bottle at that temperature, so I keep it warm if I was going to mix some fuel.

What brand of blanket do you use Andre?

I wouldn't worry about synthetics dropping out of suspension after mixing. Might shake the can a little harder when mixing any oil in real cold weather.

Her name is. Well I'll just leave it at that.[emoji6]

Logged with a 385 and 395. Ran a 390, but not commercially.

Still logging?

No.
