What oil is best? and what ratio?

[mdavlee]

Some of the brownish stuff reminds me of model car and airplane engines running nitro fuel with castor.

The piston top is similar to what it looked like after milling in the middle of summer with 800 at 32:1

Wish you would have suggested that b4 I cracked the piston trying to remove the wrist pin. Way to wait in the wings dub

I got some small saws today, I could donate one to the cause.

Polymerized. That's the term. It looks like the oil polymerized. Piston looks like it has melted and smeared plastic on it.

Thing is this oils performance of leaving a depoist or reacting a certain way cant be guaranteed by the manufacture so well outside of its designed boundries. It performed flawlessly as far as protection goes well within its recommended ratios. Seems to be an ultimate oil for protection? Its very interesting to see what happens though when its pushed far outside its designed usage. Thank u for the hard work Egg Shooter!

Exactly, just like Castor oils do.

Have we all been wasting our money on the "good" stuff when Walmart oil might really perform well enough to protect our beloved equipment ?

Very well could be.

The only oil I would put up there with 800 when it comes to film strength would be Klotz R50, but it will not burn as clean as 800 when it starts to cook.

 

[Keith Gandy]

I agree Keith. This is outstanding oil and it might just be the benchmark for all the oils I'm testing. I'm willing to go out on a limb and say 100:1 would be safe in trimmers and blowers ect. in normal usage. 60:1 in saws in most conditions. Don't anyone take this as advice to do so. Just my feeling on this. Oil, as we all know has a limit and things we aren't used to seeing will appear as we go beyond its design paramaters. I'm confident no bike or OPE oil was designed to protect to the extreme this test places on them. It sure is cool to see the aftermath though.

Eventually I could see me doing a cheap oil off. That would be interesting. Have we all been wasting our money on the "good" stuff when Walmart oil might really perform well enough to protect our beloved equipment ?Guess we might find out.

It will be interesting to see top rated OPE oil compared to top rated MX oil

 

[Keith Gandy]

Thats the plan. I feel they should be judged against their own kind. OPE oil vs OPE oil and bike vs bike. How the top performing OPE stacks up against the top bike oil will still be very interesting. People can make their decision from there or stay with what they always run. Makes no difference to me. I'm not selling anything.

On the possibility of a cheap oil testing series, that will be stuff like Poulan, Walmart, ect. The type of oil many average home owners use.

The synthetic poulan and dolmar synthetic is the same I believe. Ive used a good bit of the Dolmar and like it. I like Maxima K2 the best of all Ive tried

Internal pics of the RA test rig. Its getting a near new specimen. Hard to get pics everything is so shiny inside. Machine marks all still visible ect. No melted plastic.

Man the casting is rough on thoso transfers!!

Definitely rough. But the exhaust port actually looks really clean. I wonder how the inside of the cylinder ports look, from what I can seeing the pics of the one port it looks really really nice.

Weather permitting, RA tomorrow morning begins. Got some thunder boomers oot right now. View attachment 234592 View attachment 234593

Best I remember the original RA I have is ester based and new the formula you have there is non ester

Here is what I have for new and old Red Armor.

 

[mettee]

I'm really liking the red armor

 

[andyshine77]

No idea. It was donated. I would have ended up getting some from the Home Depot eventually but this showed up in the mail. I remember reading the formula changed in this forum way back but I didn't pay attention to how the bottle has changed to indicate which version it is.

If you need any other oils later on just ask, I have quite a collection and likely have it on hand, I need to thin the herd anyway.

I’d like to see how HP2 holds up

 

[Bjorn]

Hallo. I am a strong beliver on Castrol oils. Can you make a test of this oil. Regards Bjorn

 

[mdavlee]

I’d like to see how HP2 holds up

I used it for a milling saw since it was cheap and on the shelf locally. It did carbon cost the whole top of the piston pretty good quickly but nothing awful.

 

[Moparmyway]

It's doing what the last trimmer did on the 200:1 800. Rpm drops then it speeds back up.

Is the spark plug fouling ?

 

[Moparmyway]

Is the spark plug fouling ?

I don't think so. It actually quit from one rpm dip.....

There’s metal flying around in the cylinder, powdery, and so fine it’s practically airborne. The piston top and/or carbon could be interfering with spark, at certain conditions.......
It begins with it, the death miss ???
Your previous oil did it at 200:1, no ?


Just how my dumb mind could see it.........

 

[Pullstart]

just for update sake. Who is winning this oil royal? Not about to look through 800 pages.

lol I think this thread will be in the 2000 by end of year! Lol!
