oil test done!

Hoople said:
Silicon can be an additive in the oil to start with, but if the oil didn't have it to start with, the main source for finding silicon in a sample (on an air cooled engine) would be from ingested sand.

On water-cooled engines with antifreeze, coolant getting into the oil would be a source.
I am sending in an unused sample of oil to get a baseline measurement. It's possible that the oil & additive I use contains a high amount to start with. That would be ok. But if my baseline is 2 PPM and the other 12 PPM are coming from sand & dirt through my air cleaner, that needs to be fixed.

I'm sure you know what happens if left uncorrected..:)

Hoople, I think you have open up a new can of worms here! I myself also run a K&N air filter that in the back of my mind often wonder if it would filter 100% of contaminants. I have cleaned and reoiled the K&N air filter and held it up to the sunlight and could see tiny holes in the filter itself, thinking some contaminants could get pass the air filter. Also I could see what looked dirt in the throat of the air intake. I know a lot of bikers run the K&N air filter because of more air flow. But if it lets sand particles thru then I don't need it!:(

Received my report and silicon was higher than I would like it to be. I am using a K&N air filter with a pre-filter bonnet. Going to send off a virgin sample of the oil I use with additive to see if the oil happens to have that amount of silicon from the get-go. You had 9 PPM in oil that was used for 2500 miles. I had 14 PPM with 2000 miles on the sample oil. That's not good.

Are you using the stock air cleaner/filter? I never really did believe K&N's principals (vibrating fibers) behind how a filter designed like that could really trap particles.

I use a k&N stage 1.

thats good that you are sending off a baseline sample. it would prove a lot and rule out all speculation. let us know.
 
Let me say that us guys that been using K&N filters on our Hot Rods (car) have know about the extra dirt problems like Sand for a long time with the K&N filters and that is why you will see a "sock" type cover over the filter on some of the Cars and Trucks at car shows. Expecially the ones with outside exposed filters !!:s

I copied and paste the file to Microsoft paint. it shows up just like a picture. then i just used the block paint brush feature on "black" color and covered up all my info. then i saved the file and put it back into my photo album as a picture. then i just upload the picture into HDtalking. hope this helps.
 
Yep, that worked. Here are my results from last oil change.

Which 20w-50 is that. Would you have a part number because I think they make a couple.
Your also running a K&N?
 
Hoop, The M1 is the 20w-50 V-Twin. I inherited a "Big Sucker" AC. Not sure how the element stacks up with the K&N. Probably not a lot different. Lots of sand around here to be sucked in the AC. I'm betting your sample comes back with high silicon in the product....Unless you have used a sealant that is in constant contact with the oil....
