Which Klotz?

[Andyshine77]

And there you have it. My experience runs right the opposite of yours. The TZ250 has guillotine style power valves and after running straight castor premix the YPVS system was well oiled but in no way gummed up. The worst deposits I have ever seen were on the piston of my FS76, after being run on nothing but Stihl orange bottle 50:1 for over 10 years the rings were glued in the grooves. Horrible varnish.


I guess it's time to post this pic again.

That jug is clean, it's always looked that way.:smile2: But the combustion chamber never seems to be the issue. I ran R50 for over two years and the combustion chamber looked just as clean, the piston crown not so much. I ran Klotz super for a few months and I didn't like what I saw at all. Stihl's Ultra on the other hand burned clean, and protected well, as I'm sure you know. Ultra must have a great add pack, I simply didn't like the smell, and gallon price. I also like the fact full ester oils are attracted to metal, and penetrate into the pores of metal, the thermal stability is an added bonus.

Well, I got into my xpw tonight. Took the muffler off and pulled the plug to check it out. It does'nt look to be that dirty at all. Theres a slight brownish color in the exhaust outlet that feels sorta sticky in a way. Very thin though. The inside of the piston and cylinder show a good coating of oil. The crown shows a black sut on top but you can still see the cut marks from the lathe on top of it so it's not that thick. Looks sorta like black ash. I would think thats pretty good considering it's probably had around 75-100 tanks of 45:1 with the R50.

I tried to take some pics but my camera isnt up to the close ups. If any of them are worth posting then I'll post em up in a few.

Good to hear it's working out for you. R50 probably runs cleaner at 40:1 than say 32:1, it's a very consecrated race oil.

Yea Andre, it looks about like you explained before. The piston and cylinder are very very clean and theres absolutely no wear at all. This saw should have about 200+ tanks on it now. Hard to keep up after so long.

The only dirty places are the slight brown varnish on the exhaust outlet and the black crust on top of the piston. I can scrape it and it's like ash. i guess it's natural?

Still, I'm thinking of trying the MAxima K2 or the Belray H1R.

 

[Anthony_Va.]

Heres a few of the pics. Don't know if they'll show anything. The last one you might be able to see the piston top.

 

[Anthony_Va.]

They didnt show. I'll try again.

That's awesome looking, very similar to what I experienced with R50.

Here's a pic of my 7900's piston from the exhaust port. Like in your pics the ring is clean and you can still see the machining marks in the piston.

 

[RiverRat2]

I'm gonna go with the Bel-Ray H1R.
I just ordered a liter of the Bel-Ray H1R for 21.30 just like stumpy had posted.

Did you order from Stumpy????

after all he is a site sponsor!!!!

I'm just sayin!!!

Those pistons look real good,,, R-50 @ 40:1 is a good ratio I think!!!!

Just for fun, I mixed some Benol with Motul 800 to see if they will mix and they do mix nicely. This gives a synthetic / castor that also runs cleanly, and protects.

Motorex Racing GP is simliar castor blend and JASO FD rated.

update

I picked up some H1R and K2 awhile back, I shared half of it with a couple AS members for their valuable input I really liked both, but seemed to like the H1R just a fuzz better. It has a better smell to it,, which sounds dumb, but my head cant take much of the smell of some oils. Also I think the H1R burns just a little bit cleaner than the K2, but doubt its enough to make that big of a difference over a period of time. I know I have about 10 tanks of H1R in a popup 066 and the piston crown is just as shiny as the day I put it in.

One thing I don't particually like about it, I found myself having to open up the high sides a bit more in every saw I ran it in....more than I usually would. If Im cutting with some buddies I wont let them run my mix in their saw unless we adjust for it. I had to open up all my saws between a 1/8th and a 1/4 turn. I guess the H1R must be heavier or thicker or something...then again it may just be my saws .

With the K2, I couldn't really tell a difference in the tune over the Stihl Dino or Ultra. I ran the K2 in several saws that were tuned on Orange bottle, Ultra, Husky Low smoke, and Husky XP, and never had to make a carb adjustment for the K2 that I can remember.

Im 100% positive there both great oils, as they should be. Im out of H1R and have just a bit of K2 left, but I just ordered myself a 4 liter supply of the H1R, and got 2 liters of the K2 for my cutting friends.....had to take advantage of the free shipping .

I'm gonna stick with the H1R Durand. I like it better than any oil I've used to date. Like you said, it is a super clean burning oil. Klotz on the other hand left behind some nasty deposits.

The K2 is still in the bottle......I only mixed one gallon of it. Nothing at all wrong with it either. I just like the idea of finding something that works and sticking with it. The H1R works for us.

Hmm,

I hear this quite a lot,

Never had a problem with Klotz myself. And this goes back to the early '70s.

Can someone please show some pics of this "nasty deposit" stuff?

Same here buddy, run super techniplate at 40 to 1 and have for a few yrs, not gonna change either

Outside of Stihl and Husky oils, Mobil 2T was the only other one I ran. Liked the color and smell of that.

Back to Husky XP oil now. When that runs out, gotta find something cheaper.

Great review!! as you I like how K2 seems to not effect carb tuning as much as some of the other bike racing oils.

 

[joeclimbing]

I've been sticking with the sthil ultra but I probably don't saw nearly as much as you are. What about husky semi-synthetic?

Which klotz oil do you guys run? The stihl ultra is gone sky high at the local stihl dealer so I'm not going to run it any more. A 6 pack of ultra 1 gallon mix is a little over $10 now:msp_mad: I've ran the motul 2t 710 and it seemed fine also but a little high. The bike shop doesn't carry maxima K2.

 

[cpr]

Not so much run time on any one saw as many of you, but 100LL with R50 at something between 32:1 and 40:1 hasn't been a problem. In fact, I believe my fuel source is now 100VLL because I'm not seeing gray coating on the exhaust ports anymore.

 

[blsnelling]

I'm revisiting this topic again. I had to search a bit to find this thread.

I've been using Maxima K2 for a while now and have no issues with it. But, all the talk about Bel-Ray H1-R got me wanting to try it. I bought a small container of it at the local motorcycle shop. I'm also very interested in Motul 8002T Offroad. All of these oils will protect very well. That leaves two questions. Which one burn the cleanest? Which provide corrosion protection? I was looking at Silkolene PRO 2 SX, but saw mention of surface rust in the bottom end. Some of my saws set for months, and that's something I definately want to avoid.

 

[mdavlee]

I used some motul 2t 710 and it burnt clean with no deposits. The other 660 didn't seem to have any carbon on the piston top until I used klotz. The belray seems to need richened up some extra compared to the klotz. The xpw has been run on klotz of some sort since the other guy owned it and the piston top is covered in a black layer. It might have 10-12 tanks run through it. Out of all the bike oils I've tried so far the belray or motul would be my 2 picks depending on price. The only other oil I want to try is the husky synthetic mix.

 

[blsnelling]

Yeah, I'm done with the Klotz R50. You'll notice that it's not in my top three. I'm sure it provides phenominal protection, but I believe these others can provide as good of protection and burn cleaner while doing it.
