Went to use my air compressor today to install some molding and I can't get it to start. Its been on its last leg for awhile now, everytime I use it I have to constantly dick around with it to get it to pressure up.

I have quite a bit of molding to install so tomorrow I'm going to buy a new one. Figure on getting 6 to 10 gallon.

Should I go with oil less (what I have now) or the oil lubricated. In general is one better than the other or it doesn't matter?

I vowed to keep my OB posts now on topic but this is too much to resist

Oil free is noisier, but usually lighter and more portable.

Oil lubricated has more power and lasts longer.
Oil lubricated is better for a permanent mounted compressor.

I think the only difference is the oiled will last longer

Belt driven will last longer. But heavy.

Oiless is good for portable compressors. Oiled direct drive should give longer life than oiless direct drive.

geez...you can run 2-3 framing guns on a compressor that size.

For trim work, I have a cheap POS oilless Central Pneumatic 3.0 gallon / 0.3 hp pancake compressor that cost me $50 new.... I get 25-28 shots with a brad gun before the compressor kicks on. Fires brads all day long for anything a non-professional needs

oil less start up better in cold weather.

Other than that an oiled compressor is better. It will last you longer.

My trim compressor for the last 20 years was the standard red pancake Porter Cable every has. About 6 months ago I gave it away and bought a Rolair JC10

Both are Oil less and I used the PC compressor for a very long time. This Rolair is simply better and so quite that when you plug it in for the first time you think something is wrong.

I have an oil free Craftsman and it is so damned loud that you have to wear hearing protection when you use it. Works great but, the noise is crazy.

For heavy use, it is a no-brainer - go oiled and get one size bigger than you think you need (I recommend Harbor Freight) and pay attention more to CFM of the compressor and tool requirements, than to tank capacity.

However, to run 1 nailgun at a time, at a moderate pace, and occasionally adjust the tire pressure, etc., one of the pancake, oilless like you've been using is fine - but it is what it is - you'll have trouble running impact wrenches, impact sockets and sprayers with the little compressors.
