What oil is best? and what ratio?

[bwalker]

I wish RA mixed as easily as 2R. It's hard to strip out of my ratio-rite with fuel, kinda like Motul 800T.
But nevertheless I'm sure it'll be just fine Keith.

Most of the higher viscosity oils do this.

Before I knew better I ran tons of tcw api tc oils in lots of air cooled stuff. Most notably in some free air sleds in the 80s and early 90s only stuck one sled motor on a 45* day riding in slush snow. Now I think itsnot the best stuff but surly better then 30 wt motor oil of old days. Use it up tune a little rich and mix it a little heavy around 32-40:1 and run it. Tuning rich helps deal with the low temp oil. For that price is run it forsure.

Running a marine oil richer will just gum your motor up sooner. The problem with marine oils is two fold First off is the fact that they don't use detergents. Instead they use dispersents, which do not work at higher temps. Second off they use heavier base oils to deal with the higher loads of marine engines. These tend to not combust fully, nor cleanly in OPE engines which are not loaded nearly as hard as an outboard.

Yep. Does this property help the oil stay in suspension?

I hadnt had that trouble. Dilute it with fuel and stir it up and give it a few minutes

This stuff can be bought at my local coop for 75 cents a quart. They have cases stacked up of the stuff. Nobody will buy it since they offer opti and some tall timber synthetic. Anybody thinks of a use for it or wants some let me know

I'll dump a little fuel on top of the RA in the ratio-rite and give it a mix. This stuff really sticks.

Esters tryin to do their job!! Lol

Does it stick to the metal the same way?

Penzoil makes my boat smoke going slow under light load

the oil is blue though so it is good.

Quote: Polarity also causes the ester molecules to be attracted to positively charged metal surfaces. As a result, the molecules tend to line up on the metal surface creating a film which requires additional energy (load) to wipe them off. The result is a stronger film which translates into higher lubricity and lower energy consumption in lubricant applications.

RA is only about 9.7 I think

 

[Stihlsmoking]

If it is TCW, then I wouldn't use it.

Maybe I'll do an experiment an run it in one saw that has a fresh piston and see how it does or how long it lasts ? But won't be running in my new MOFO 360 ! It's getting Motul 800 or amsoil saber.

32:1 tuned a little fat it might surprise you

@jake wells this is the back and it is a really dark blue in the bottle.

 

[Keith Gandy]

RA viscosoty is 10.3 cSt at 100°C

If not I have doner saws, I'll just build another one. Lol

that stuff is OLD tcw 3 came out around the early to mid 90's
