PJ1 5-20-2PK Foam Air Filter Oil, 26 oz, 2 Pack

Works great and a great price

It is what it is and does what it is supposed to do. I will point out that like any particulates barrier you need to clean the filter at least every 90 day. I check the condition of mine monthly.

This is way to go instead of soaking in oil

After using different oils on foam filters for many years, I read that there was a specific oil for this. I've used bar/chain oil, ATF and motor oil to filter out dirt particles in the foam filter before they hit the paper filter. I never had a problem. I washed the foam filter with warm soap and water, squeezed it dry and then added the oil. With neoprene gloves on, I squeezed the excess oil out of the foam with a paper towel. I guess this is a holdover from the air filter on my first car, a 1964 VW, where the air filter was an oil bath. (Yes, this guy is old!!) So, is this stuff necessary. The experts say yes. So, we'll give it a try. It can't hurt ($-?).

Great product

Works great, much better than squishing a filter around in a plastic bag with oil

Good quality, long lasting. Easy application.

Great product. Helps with the life of the filter and for clean air flow into the engine

Great oil for RV foam filters
