<strong>Yahoo Message Number: 20498</strong>My rigs LP generator just hit 150 hours and I've just changed the oil and filter. Very simple to do! It also called for the air filter to be cleaned. I had an extra one so I replaced it! I have an Onan RV Gen Set Service manual, but it wasn't very specific on the air filter issue. Since I've replaced the air filter, do I need to dab some oil...
