WHAT IS THE BEST OIL ?
Blendzall is not just a 2 cycle oil. Blendzall Castor is also the ultimate "top end lube" for a four stroke. Even with space age technology, castor oil is still the best lubricant on earth. Castor migrates towards hot surfaces in your engine. And yes, it has that racy odor. Myself, ex ported RZ 350 YPVS owner, currently zx 750 owner, and my riding bud on his busa, both run an ounce of "Blends all" in our tanks at fill up.(+300:1) We both found it quite common when another rider smells this fuel/exhaust and says "are you running race fuel?". Or the old "are you running that thing on nitro?". Or the, "hey, that smells good".
RUNNING AN ENGINE WITH NO OIL FOR MANY HOURS
Blendzall Experiment: Before winter came in I put an old running lawn mower out in the middle of the back yard. A FOUR CYCLE LAWN MOWER. I filled it with 50:1 Blendzall Castor Premix. Mower started on the second pull and was allowed to run two minutes. Mower was killed by using the choke lever. The mower was left outside with no shelter in the middle of the back yard all fall and winter. November all the way Thru February. During this time the mower engine was often buried in 2 feet of snow. The mower went through quite a few ice storms, blizzards and major rai. The poor thing has been through a nasty midwestern winter directly in the elements. Might as well have been underwater for three months. It's now February and time to TRY to start the mower. No change of gas or any tinkering of any kind allowed. No using choke! Nothing but pulling on the mower string exactly as it was left last year. THE THING STARTS ON THE THIRD PULL! And that's not all. This mower does not have oil in the crankcase! It Never did. It always leaked out. I guess you could say since it does not hold crankcase oil, I converted it to a 2 stroke. I have been waiting for it to explode. One thing I also neglected to mention. I have been mowing my yard with this mower for two seasons now with no oil in the crank case. The only engine oil this four stroke engine is getting is Blendzall premix in the fuel. I have forty plus hours on this engine like this and it still has not went POW! How could it have survived all this time? My theory is, once vaporized, fuel/blendzall has made it's way into the crankshaft area. Only a very fine mist of oil in the fuel is keeping engine parts alive that are supposed to be soaked in oil. Perhaps only a few drops have seeped in and are keeping things alive. I think it's safe to say a few drops of oil here and there have been doing the job of a quart for many, many, many hours of operation.
UPDATE 5-18-08!!! It finally went POP. Here is how it went down. Today I decided to mow the entire yard. It Started on the first pull as usual. After warmup I was mowing grass. I noticed no knocking or excessive smoke. The only thing I did notice that was not usual was smoke coming out of the crankcase breather tube. It was 2 stroke smoke. Blue smoke. I found this odd but thought it seemed to prove that plenty of two cycle oil was getting in the crankcase of this four stroke running without oil. The smoke out of this little tube started to increase as I mowed. Right when I was through mowing my huge lawn pushing the mower down the sidewalk it started lightly clunking. I ran for cover but wanted to see it konk out. When I got about 20 feet away from the mower it went "PLONK!". Directly after this abrupt noise, 2 large pieces of metal came out of the side of the mower at slow speed landing 3 feet away. After this, the engine continued to spin for a good 15 seconds. When it stopped I walked over to the motor to see that there was a hole in the side of the crankcase the size of a fist. What shot out the side? She threw a rod out the side.
Amazing how this engine lasted with 30+ hours operation without oil.
Just a shot of Blendzall in the gas tank.
Disclaimer: Don't try this at home. Running engines without oil is dangerous. If you plan to use 2 cycle oil as a "top end lube" on a 4 cycle engine, mix at 300 to 1 ratio. Too much oil in the fuel can mess with "jetting" and cause deposits. The views and opinions expressed on this page are in no way affiliated with the company Blendzall. I am just a fan that used to smell Blendzall at the Kart track when I was a kid. Just about every motor sports enthusiast has an oil story to tell and this has been mine. Also keep in mind I am also a true fan of Klotz. But that is another page.
