Oasis service

[RVific]

I'm getting ready to service my oasis system. The videos online are straight forward. I have one dumb question. The directions state to fill the new filter with diesel before installing. I don't have any fuel on hand. Will it be enough to just dump fuel from the old filter into the new? Do I need to purge air from the line? Can I just keep restarting the burner until the filter fills? Thanks for the help!

Yes you can dump diesel from old to new filter- just be sure it's full so you don't have air in it - I use a little diesel fuel stabilizer - Stabil- or diesel fuel additive to finish filling mine if I spill a little fuel.

Don't pour the contents of the old filter into the new, you are pouring what was filtered into the new filter.
Assuming the new filter holds one qt., buy a qt. of power service diesel kleen fuel additive to pre-fill the filter. This has an added benefit of cleaning the entire fuel system downstream from the filter.
I have done this using Power Service 9-1-1 emergency anti-gelling additive, but I doubt it has any cleaning effect.

Your suggesting that dumping dirty fuel out of the old filter into the new one is the way to go ?

Filters collect grime and water, any fuel in an old filter is bad.

Keeping a couple of quarts of Power Service Diesel Kleen is good for an on road emergency if you need to change fuel filters. It's readily available at Walmart.

Only in an emergency would I ever use the old diesel fuel from the filter. I just changed my fuel filters the other day and the fuel that I poured out was pretty clean, but it goes against my grain to ever use it, unless I absolutely had to.

With that said, anything you add to a new filter should be poured into the filter around the outer edges, keeping the center hole plugged with a cap or a clean thumb. That way, whatever you add will get filtered before going into the system.

Lastly, when changing the Oasis ignitor, note it's position "clocking" as it only goes back in one way, so the retention clip will fit. Keep the ignitor as a spare, as I've had one go bad in between servicing.

When I changed the filter in my oasis I knew I was going to have to fill the filter so I bought a small 1 gallon gas can and filled it with diesel fuel to fill the filter. What was left afterward I poured in the fuel tank.

I didn’t know if I could use Power Service straight or not…. But if you can, that would be the way to go….

That's exactly what I do as well. However I also carry extra Power Service Diesel Kleen with me in case I need to do an emergency filter change while on the road. I haven't needed to do that yet but it is better to be ready than to be caught unprepared.

Where is the best place to get the kit?

[Dutch Star Don]

I buy mine directly from ITR (Oasis), the last one was about $110.00, which includes the filter, ignitor and a couple of air filters. I think others may have pieced together kits from other sources. I prefer to go to the manufacturer.

NOTE:...On one occasion in the past, I had an ignitor go bad while on the road. I keep a spare service kit with me at all times and swap it out with the new one when I do a service. I used to service the Oasis once a year, but for the few times we use the diesel burner, I now do it every two years and change the fuel filter about every 4-5 years. It just doesn't see that much fuel flow.

Correct or not, it works. When changing engine or Oasis filters, I buy a quart (or 2) of automatic trans fluid to pre-fill the new filter.

Agree with DSD.
ITR isn't the cheapest, but I know I'm getting OEM and the best quality.
I keep the old ignitor as a spare in case of emergency.
I always fill the new filter with clean fuel with a plug in the center hole and fill around the perimeter. I also pinch the fuel lines to avoid any spillage.
Previous coach had an AquaHot. Oasis is so much easier to service.

Thanks DSD and MikeyG....
Will be ordering in the morning.

10-4 Tom.
See ya at the end of April.
Looking forward to the rally.
