DEWALT Compressor Oil, 1-Quart (D55001)

It worked great for my compressor

I purchased a Craftsman Professional 27-gallon vertical compressor, with the American-made Devilbiss tank, which has suited my needs beautifully. Of course, the manual states you should change the compressor oil every 6 months or so and in small print on another page, they say you MUST use a synthetic compressor oil. Bummer. All that Sears sells is dino oil and I bought four bottles of it on sale because the showroom rep told me I'd need it. Realizing he sold me what literally amounted to snake oil, I took the bottles back to Sears and after arguing the point with a manager, got a store credit. Fine, whatever. Off to the internet, and of course, Amazon didn't let me down. I found the DeWalt synthetic, did an oil change (and an air tank petcock change while I was at it). The old oil was original and had tiny metal flakes in it (probably because I had to top 4 oz off with the dino stuff during break-in). With a full tank of new DeWalt synthetic oil, the compressor runs like a WHISPER! I thought it was quiet before, but WOW! It's just a lovely putt-putt-putt-putt-putt when it's running now. I couldn't be happier. Pricey? Yes. Worth it? Absolutely. :-)FOLLOW-UP - 8 months later:I recently used my Aircat angle grinder to strip the powder coat off a 10-square foot piece of metal (the bottom plate of a synthesizer I'm restoring). It took about 3 hours and 5 roloc discs to get the job done and the end result was superb. The compressor ran non-stop for almost 2.5 hours at one point just to keep up. The next day, I had a look at the oil and it still looks as good as new. I'm totally sold on this DeWalt synthetic stuff.

This oil meets or surpasses manufacturers requirements. Cost wasbhigher than expected, but what isn’t?

After I put the new oil in my air compressor, it was much quieter, I think it’s good quality oil.

I am a big dewalt fan so naturally i would use OEM dewalt oil for my new 30 GAL Dewalt compressor, this is the first oil change from the factory, i want to use what Dewalt recommends for obvious reasons. My Compressor was a sizeable investment. It quieted down the pump quite a bit. Good oil, but again its really pricey.

Been using this in my dewalt 60 gal air compressor for 6 years and my compressor works hard every day still going strong

Pretty color blue LOL. Just changed the oil in my compressor so can't say much. It's compressor oil

Not bad oil, most all reciprocating piston air compressors could run this oil. For those that don’t know your looking for a non detergent oil usually SAE30 weight. Sometimes you need to check on the ISO number. I think my ingersoll units at work take a iso 128, all season. You should know if you switch from mineral base oils to synthetic you may cause a washing effect on the compressor and need to change to oil again after a short period. Non detergent compressor oils do not wash out all the debris from the crankcase. Other suitable oils would be speedair recip oil, iso 100, 30w, mineral or synthetic, Mobil rarus 427.
