What oil is best? and what ratio?

[andyshine77]

To be clear I was talking about K2, only ran about a gallon of Dominator, ran just fine. So no opinion on it causing corrosion, other than like any other oil with a high percentage of esters it's prone to bring hydroscopic, but good additives can and do help negate that issue. I know Randy seems to like Dominator, that's good enough for me.[emoji111]

Lol

I’ve heard of the rust with Dominator but have never see it. Amsoil has excellent products but i agree their marketing is sketchy.

Top Notch products with some infomercial like marketing. And in more than a couple saws Saber @ 100:1 didn't work out so well, specifically Christopher's nice 441. I posted the pictures way back, had Mike Sullivan, Erick, Brad, Christopher and my late friend Nik AKA Fatguy all look that saw over. Nik cut the cylinder base and gave the piston a nice big pop up. Miss those days in the shop.[emoji22]

Nik was a top shelf guy. We had a few very interesting talks together. He knew people and machine work well. Take care Nik.

Just because something is legal, doesn't make it ethical, or not giving the appearance of being shady. The 441 was what I'd call an oil related near failure, but that was at 100:1 Other than some Husky saws requiring more oil because the bottom ends are under built, I have not seen an oil related failure at regular ratios with any oil.

I've heard of rust with other ester oils like 800 and K2. Never seen it myself so you won't see me promoting the fact that they do. Those are full esters as well. Dominator, is at most, 25% if I recall from the MSDS. Rest is most likely PAO base oils. Several different PAO oils if I recall from the MSDS. 5 different oils I think it listed. I also never let any engine set more than a couple months. I run them all.

I didn’t promote it. I was agreeing with you about hearing it but not seeing it. I posted that a while ago too. I have some Dominator and Saber and would use any other product as well. I just don’t buy the 100:1 and once a year oil changes. Could be perfectly fine but not for me.

@full chizel

I do the once a year or 15,000 mile oil change and have for years. We stopped doing UOA because they always say we can go longer. About the same price to change vs UOA cost. We did it with Mobil 1 and have since 2007 or 2008 with Amsoil. We only use their filters and Signature Series oil.

I’ve just went by the OCI and got about 8500-9k miles with Pennzoil Ultra Platinum. I’m sure I could go longer I just feel warm and fuzzy changing it then because i do some heavy towing during the summer . I guess its like the 50:1, 40:1, 32:1 debate and do what feels right.

 

[andyshine77]

I believe carboxylic esters are the most prone to corrosion. 2T oils don't normally use PAO base stocks. Dominator likely has carboxylic esters and a lot of PIB, much like my favorite oil if all time, Mobil 1 2T. Because of the alcohol and fatty acids carboxylic esters most certainly have corrosion issues, this is not conjecture! However with the proper formula it can be controlled. That said even with the proper formula I have seen some evidence in engines that sit. So my advice "for whatever it's worth" is if you have a piece of equipment that may sit, as a precaution choosing an oil with the proper formula may in fact be a wise decision. It is up to the individual to make that choice based on what information they have seen, heard and whether or not they believe that information. If I'm wrong and ester oils will never in a lifetime cause corrosion, yet you choose to use a non ester oil because of corrosion concerns, what did you really loose? Heck I use K2, but I understand the possible risk, the positive outweighs the negative for me. I simply try and provide the best information I can based on experience, research and knowledge passed on to me. I also mostly enjoy the convention as well.[emoji111]

Exactly I'm the same way, but 5,000 for me, every vehicle I have a owned has now gone over 250k. If it ain't broke don't fix it.[emoji106]

 

[qurotro]

I run my stuff at least once a month. I use Saber and it served me well. I bought K2 because of this thread and hearing all the good things about it long before I addicted to lawn equipment lol...
And picked up a pint of 927 just to smell the exhuast

8 years that's a good long while, Kevin has been running it at least that long and hasn't seen the problems he did with Super. How shelf stable does it seem when mixed? I know R50 would turn real dark after a few weeks, don't know if that was just the dye or something something else.

I used some mix in e free pump gas 1.5 years old I put in a VP 32 ounce can when I found it. It was my tractor fuel when I was carrying just a quart and pint of bar oil for backup in a little bag.

 

[mdavlee]

K2 would separate from gasoline? Hm... Maybe I should not use K2? I dont run my saws very often. Saber prevent internal rust for me. Just changed to K2..

It was oxygenated 110 octane stuff with alcohol in it. That was the only explanation I could find after tear down and then losing compression. Maybe 2 weeks of sitting between uses. Neither were acting like they were tuned lean and one was 1500 under spec milling and the other was auto tune

 

[mdavlee]

@mdavlee
E free is so much better for this and not wreckin stuffs. As you well know.
Enthanol laced fuel has to help cause corrosion in a setting engine in more places than just the carb.

I was trying to test higher octanes to see if I gained power. Cut times kept slowing down with more than VP 94. It was right behind 87 pump gas. 110 was a lot slower even with saws over 200 lbs compression. Plus the alcohol and other stuff doesn’t play well with all oils. That was my main reason sticking with. Klotz original. It will mix with pure methanol no problem.

 

[mdavlee]

Nashville hot bacon from Kroger with jalapeños for that little extra kick.

 

[ayoungtexan]

I use 93 e-free pump gas. Neither me nor my father have had an issue in 20 years on this gas.

 

[mdavlee]

Its 90 e free for Everything else at this time.

I have boat 90 1 mile from the house. I don’t use it unless it’s this time of year when it gets turned over pretty good. Winter time it is old and doesn’t run as good.

 

[qurotro]

Hmm.. This corrosion stuff is interesting. I have a bad crank, I would degrease it and cover it with K2 and see what happen. Maybe bag it in plastic to get more moisture.

Crank the equiment more often or sell the equipment if it isnt being used? Fog it with fogging Stabil spray
