Tech Info: Oils

[bholmes]

Jock, might be a good idea to post the oil article in a FAQ section or as a sticky....or maybe it was and I missed it because i'm a looser LOL either how....

i still run castrol R30 40:1 sometimes 50:1 in mine...those who follow me love the smell of burnt castrol...its one way to lead and smell good whilst doing it....lol...on internal inspection though leaves a hell of a lot of carbon residue sh_t...nothing  that doesnt clean up with kero and  thriple 0 steel wool

im mixing 40:1 Yamalube and it works in everything from my leaf blower to the IT200

Wow, with today's oil technology I'm surprised that someone is still using Castrol R, talk about old school.  Personally I wouldn't touch bean oil with a barge pole, it gums everything up big time.  OK I suppose if you're into tearing engines down every 5 minutes to clean crap out of them.

The only thing in it's favour, is when used, it sure smells like a 2T's should. 

Personally I use Silkolene Comp 2 at 32:1, works OK for me.

Cheers

Yeah bigbird i run motul 800 @ 50:1 in my ktm 360 and it runs clean as a whistle.Will probably knock the IT250 back to 40:1 or maybe 32:1

When i bought the KX60 they musta ran Castor Oil in it.. Had a bad time cleaning out the carby was all crusty with yellow scum.. Although smells beautifull.. Not good for the extra work.. I hate work..

super M all the way at 40:1 never had a problem with foulin plugs gummin up the cylinder or power valve and top end lasts longer

Hey Cookie, I tried the Comp 2 and found the Comp 2 "Plus" mixed with fuel better (not as thick) and has smokes less than the Comp 2. It's a couple dollars difference from memory so I believe it was worth the extra. It's designed to be cleaner on the power valves (even though you may not have them!).
I think if Silkolene starts again with the naming conventions it would help product sales. The only way to work out what to use I found was to email or ring them up! Labeling and descriptions are a joke. Idiots.

[Cookie]

Yea, Axel I noticed that with Comp 2, the bike is putting out a smoke screen that James Bond would be proud of.  I'll try the Comp 2 plus next time.

Cheers

For years we ran a BP powerstroke senthetic in our motocrossers as Dad used to be a BP agent, We had no problems but this was in the early ninties. I once used some ELF premix which the local dealer gave to me to try, I seized the main bearings first race on my KX250. I used mobil in my cr500 for a while but it scuffed the skirts, now i only use motul 800 at 32.1 in the 500 and 40.1 in my KTM 250 as for the WR500 i havn't had a air cooled 2 stroke before but i will try the motul probably at 32 also. I also raced the finke desert race a few years back on the CR500 and ran a couple sizes richer on the pilot to stop seizure on back off, also you can hit the kill switch to stop the spark on rundown if you are still worried. I had the mixture at 28.1 for a bit of security as well

     I think your pretty right with your assesment jock i can remember when bel-ray and a few of those other so called 2 stroke  oils first came out the makers all said its dear but you can run it at 100-to1 that turned out to be frogs  crap with motors seizing up all over the country  when tested it was not much better than  (KEO  ::)ENE  ) thats why pistons look shiny and scratchy with no carbon deposits on them .  me i use  33.1 yamalube with a dash of upper cylinder lubricant with it this keeps the plug clean and the bearings and seals lubricated  (oil is oil)  dont worry about a little bit smoke its when it stops smoking you got a problem .  Poppy

I have used em all..Belray, Amsoil, BP Syn, Castrol Syn. Motul Syn. The lsit goes on. I think the best oil is the one that is cheap and has reliable viscosity and dilution stability. The Shell sx2 semi syn is a pretty good balance. I run all my ratio at 40:1, jetted and plugged accordingly. I have never had issue with seizing or big ends jumping out of bed. And at least I can afford it. some of thos full syn are very dear. And to my best understanding I cannot see or feel the difference

When i just started,y bike up again after 15+ years, I went with what was still sitting in the autolube tank - i think it was castrol mower mix oil? It was flouro kermit green and really thick

Switched to Penrite Hyper now (on advice from here), at whatever ratio the autolube is putting it in at
