I went to my local shop today to get some Maxima SuperM, to my dismay they were out of it. The only Maxima products they had left were Fromula K2 and Castor 927. Each was a 16oz bottle so I picked up one of each. I've never used either one though I have heard Castor 927 is good oil but very dirty and gums up the powervalve...it does smell good though. I know nothing about Formula K2. I run my SuperM at 50:1 and plan on using this oil I got at 50:1 also. So are both of these oils good to use at my dilution? I'll try again this weekend to see if they have my 16oz bottles of SuperM.

:? ya not to highjack but whats the deal when the bottle says mix at 50:1 and the bike says to mix at 32:1? The synth is that good it protects with only 50:1??
Alot of guys I know swear by the Castor927...and it does smell great...you know when your behind a bike running it.... :mrgreen:
-
where is BDI on this one i know he like that K2 stuff. i personally like 927 mostly for the smell.
-
I run the Bel-ray H1R at 40:1 or even 50:1 without any issues. The synthetic's can safely be run at 50:1. The Amsoil Dominator can be run at either 50:1 or even 100:1 per the bottle and I've read of people running it like that!
-
I've always used Castrol TTS (or R2 when they sold it). Never had any problems. I did hundreds of (abusive) hours on my '95 KDX200 at 32:1 using it, that thing just kept going and going. I also use it in my KTM SX200 at 40:1. I think I'll leave the 100:1 for someone else to try :) I'm going to stick with what's guaranteed to work.

I've used 927 for quite a while and never gummed up anything on my '93,,,but I run the desert with its higher speeds.

I'll try again this weekend to see if they have my 16oz bottles of SuperM. i don't care if i run the best oil it will always be 32:1factory knows best and makes the motor last longer and the more oil (within reason) means more power,better lubrication the to main bearings,much better ring seal and your bike will love it ,try some motul 800 synthetic,smells awesome to..
-
well I got my SuperM over the weekend so I'm happy now. :-D
I gave the 927 to a friend that uses it but still have the Formula K2...nobody has any opinion on Formula K2?
-
Switched back to Castrol 927
going to use the interceptor for chain lube.

Do you run it at 32:1 ?
-

my trials bike stuck a piston on k2 the week I swapped to it. That's my oppinion of it
-
like I said, since I stocked up on SuperM I think the K2 will go in the weed whacker and leaf blower :-D
-
Been running Klotz R50 at 40:1 for the past 20 years. Not a single engine issue (at least related to oil or premix ratios). After pulling powervalves on a Klotz oiled engine the power valves look really clean.
-
Been using Blenzoil Green Label 40:1 love the smell and it coats the top end very well, the neighbors love it when I clear the pipe
-
Ive run the Castor 927 since day one. Love the lubrication and smell.
-
Maxima Caster 927 was developed in conjunction with Maxima/Roger DeCoster Team Suzuki for Ricky Carmicheal when he was still racing his RM250 2 stroke. I ran Maxima Super M since the 80's. I have recently switched to Maxima Caster 927 since it was the latest and greatest. The bean oil has superior ring seal and lubrication under high temps. It has never failed me. I believe it's a great blend and great oil.
-
There are alot of good oils out there but you have to run the ratio at the oil companys recommend ratios.
-
Maxima Castor 927 has been around for more than 20 years, long before Ricky was even thinking about riding a 250.

Can you explaing this in more detail, and why ?

I've run 927 in bikes since before Ricky was in diapers. Don't know where you heard that it was developed for him...
Also in kips land the 927 gunks them up.
927 also will separate in cold weather and in many race fuels (low specific gravity). It's a great oil just need to know what your dealing with.
I also don't trust oil manufacture recommendations. How do they know what I'm runnig it in? Bly low rpm trials bike has different oiling requirements than a screaming banshee. (amsoil 100:1 comes to mind. scary)
-
motorrad
You what to run the ratio that your motor needs for the depend that you put on your motor. You would gum up your kips if you run 927 at 24:1-28:1 with rich jetting cruising around your local riding spot. I got 20 hours on a topend running 927 at 20:1 and the kips look good with correct jetting.
-
An oil manufacturer premix ratio is based and the concentrate of the oil. 100:1 is not "scary" when you realize that the 32:1 takes more to mix with 5 gallons than 100 or 50:1. That tells me that the lower mix ratio is obviously "watered" down because you need more of it to maintain a good lubricating property. I ran the Amsoil 100:1 in a quadzilla for the better part of 10 years and performed excellent!!! The power valve stayed real clean too. I run Amsoil dominator @ 50:1 in my K5 and it is the best oil I have run, I have run the others too.
-
i was a big amsoil guy but had fast piston wear since then went away from it. i've pulled piston out of motors that have had 5 hours on piston and had crazy wear. All 2 stroke piston need to be coated to fix the issue with new oils out there running less oil. But that doesn't fix the rings problems.

I digress, to say Maxima 927 was developed for Ricky Carmichael. The article I was referring to is in Motocross Action July 2009, page 74 where it states that "Super oil actually begin it's life as a two-stroke pre-mix. When Ricky Carmichael raced a Suzuki RM250 two-stroke, Roger Decoster looked into every possible way to increase performance. He discovered hidden horsepower in premix oil. With the help of Maxima, a special blend of two-stroke oil gave Ricky two more horsepower." I still think it is the Castor 927 pro-series (the latest & greatest blend). As to Maxima Castor gumming up motors, I run it between 32:1 and 40:1 depending on displacement with a properly jetted motor, and it works fine for me racing motocross WFO - pin it to win it baby!!!! :-D

Bean oils are great, but can be spoogy. I find they work best with race fuels and I think they were intended to be used with that.
The pump fuel we are getting from the feds is junk now. I run 93 with stabilizer and yamalube R
If i could afford it I would switch back to race fuel and 927
-
Any opinions on Sprectro Golden 2-stroke premix oil? I have used it in the past in a previous 2-stroke life at 50:1 and never an issue. Up until recently, I was solely on 4-strokes so this topic never came up. It is good to hear about everyone's experiences...
-
I mainly see different piston wear from motor i've done and customer has me rering then after 5 hours and i measure the clearance and look at the piston wear. And these are mostly the same model motor and i get feedback from customer on what oil they run and what ratio they run.

Well stated.
You should NOT run castor based oils with powervalve engines. Castors do offer superior film strengths, but at a cost of excessive "goo" buildup. Castors are primarily used in race kart race engines that don't use power valves.
-
I read an article once talking about the really high mix ratios with testing done etc... It pretty much said it depends on the application of the motor. They suggested more oil the harder you run the motor and in small motors that are always run hard (125s etc...).
Anyhow, I run dominator 40:1. It doesn't gunk my motor and I prefer to be on the safe side.
-
I am luvn the Cast927! Sticking with it now..32:1
Nothing like a well tuned machine
