Air filter oil

[fastwillie8568]

What oil is everyone using to lube there air filter. I am still using regular motor oil and still using gas or solvent to clean them, or should I be using the modern sticky oil?

BelRay filter oil is the best I have ever found.  Kind of expensive, but well worth it.

Belray filter oil here too and I use the Belray grease on the filter sealing surface.

I strongly recommend moving away from using gasoline or other solvent for the cleaning, and motor oil for the oiling.
I use a spray-can filter cleaner designed for just that purpose.
Currently using PJ-1, but there are a number of sources.
These cleaners are biodegradable, and water soluable...just put on your nitrile gloves...spray the filter...hose it through with the garden hose.
That cleans it about 95%, and cuts through the tacky filter oil.
Then wash it out in a bucket of warm soapy water, followed by a rinse in warm clean water. It will look like new.
Allow to dry completely...then oil using a filter oil or spray desgned for that purpose...not motor oil.
Sounds like alot...but takes less time to do then to type this post...
Engines like clean air...

I would question first what type of foam media you are applying it to.  One of my bikes I have a Uni filter on and other(s) No Toil.  The UNI uses oil in a bottle and a spray cleaner followed by a rinse and dry.  The No Toil uses a spray oil a powdered cleaner dissolved in water with a rinse and dry and oil re-application.  My preference of the two in the No Toil system.  It just seems a little easier when you can keep the cleaner water available to wash you hands clean once you have the foam re-oiled for use.  [^]

I used Bel-Ray for many many years and it is VERY good, but I started using PJ1 spray on filter oil and spray on cleaner. The PJ1 spray on oil is every bit as tacky as the old Bel-Ray blue, but its SO much easier to apply, and with the spray on you get a nice thin even coat. A common mistake people make is putting too much oil on a filter which is easy to do with the pour on Bel-Ray. The spray on cleaner is nice too.

I started using No toil  years ago, and I have had good luck with it, I am not sure if the other water based products do the same but I have noticed that if I need to leave the bike sit for awhile, the oil on the filter begins to harden and I have to wash it again before I ride that bike. So now if the bike will not be used for a few months, I clean the filter and instal it but do not oil it up until I am ready to ride again. A bit of an annoyance but not a deal breaker, I like how the product works. I have used one or two others that are similar and they seem to work pretty well too.

I used filter oil to adjust my jetting. If the motor is running too lean, I apply lots of oil, too rich = thin coat of oil.
