I just purchased a quart of Velocite 10 oil, based on what I read on this thread. Just checking so I don't screw up my old Super, can I use this in the super in place of the old CPI oil I have left from when I was more active in the hobby?
I'm getting more time to enjoy tinkering with the gear now. Also, non- detergent oil in the 1040 head, right?
The oil I have has been sitting around for a couple of years.

So the general consensus is that either 30 weight non detergent or ATF is ok for a century intermittent? (I'm presently using 30 weight non d in my own machine.) By the way, what exactly is century damping fluid assuming there will come a day where you can't find FD-120 anymore.

I believe the damping fluid is mineral oil.

No two dampers are alike in clearance so it was not in anyway a precision device. Probably anything from Mazola to olive oil will do. [puke]

Andy Marglin of Kelmar fame tested several formulations of "dampening" fluid. They are NOT all the same. Wow and flutter can be manipulated with changing fluids. Louis

Aside from making a poor joke, my point is the Century devices were so poorly made just putting in the correct fluid would sometimes lock it up, while other times you could not tell the difference between full or empty.

LOL! "

quote: Steve Matz
I'm old school and believe synthetic oils are for lazy people that actually believe your engine should not need an oil change for 20k....

If you ever tore down a Christie Ultramittent that was 15 years old and ran 7 days a week six shows a day and saw how clean and clear the LaVezzi oil still was you'd be Mr. Synthetic by now. Many new cars require it and many are shipped from the factory with in already in the engine, tranny and differential. In my Hummer switching to synthetic in the drive train actually improved the gas mileage about 4mpg! In your case you probably could have gotten 2000 more revs out of your motorcycle engine's before they blew up!

Sam is right on about the century Dampner. Tolerances were so varied that some of them work well when just filled with water.

Mark,Put some CASTROL R in that Christie Intermittent or any other intermittent and check it in another 15 years [sleep]

and it will look as good as the lavezzi and with no wear to the star or cam. I will wait for your reply on the results [beer]

wait a minute did I say 15 years? [Eek!]

[note] Back in the late 60's HARLEY DAVIDSON was doing oil testing in the Race Dept. for the upcoming XR750 factory racers.
They ran several test engines with different oils running them continuously for 500 hrs w/ rpms rangeing from 1500 to 8000rpms.
after tear down the engine using Castrol R had only .001 thousandth cylinder bore wear and nil on bottomend components. [thumbsup]

Its Great Stuff even if it is Bean Oil! [Big Grin]

The problem is... Back in the 60's Harley Davidson's leaked out oil almost as fast as you could pour it in. Hence... they ALWAYS had fresh oil in them. It wasn't until the late 70's or early 80's that H-D started having the case castings and other parts in the oil flow chain vaccum impregnated with sealent. A friend of mine actually worked at the company near Milwaukee where that was done.

Your talking about the AMF Garbage years at HD. Racing Aluminum Alloy Parts(i.e.main cases,heads,cylinders,etc. have never been built in house by HD for over 40+ years.They were done by a subcontracted foundry in Ohio.The Race engines never leaked oil,just the Street junk.

I'm no lover of this Company even though I had some of their race bikes in the later 60's and 70's. We had to race ohv 500's against their KR 750's for years since they always had the AMA in their back pocket convincing them that because the KR was a flathead/SV engine with inferior breathing capability compaired to an OHV/OHC engine;saying the extra 250cc's put us all on a level playing field. [Confused]

HD Philosophy since the mid 70's in Racing is "If you can't beat'em,get'em Banned!" [puke]

Getting back to Topic Castrol R is still probably the best Petroleum oil there ever was! [thumbsup]

Mark, what was the cost and is it worth it? My mechanic said I'm looking at around $500-600 to switch in my H3 (the high price of the fluids and the labor involved). I don't drive enough to justify shelling out that much just to save a couple dollars a month in gas.

Richard...

Take your mechanic out and shoot him! You can get a Mobil 1 oil change at most oil change places for about 70 bucks. Thats what we pay for a Mobil 1 oil change in our H3 here at Grease Monkey. The other thing is you only have to change oil about every 15 K to 20 K miles. So if you had done 4 regular oil changes in 20,000 miles... we do ours once a year... those would have cost you more at 30 bucks each. I have had synthetic oil in our H3 engine since the first change and it's at 130K and runs as good as the day we bought it. Over half those miles are off roading miles too. I had the transfer case and differential done at about 10k miles. The combination of the three resulted in 3 to 4 mpg better mileage. The oil change places also do those with synthetic as well but it's so long I don't remember the exact cost. Under a hundred bucks for both though. Another thing that might matter is the year of your H3. The early ones had a smaller engine then i 07 they came out with the larger engine which we have. I can get up to 24 mpg on the highway crusing at 75 with it.

Steve Matz... My Harley days are way past. I traded the Harely for a horse. Way more fun!
