Several times over the past few years I would drive the 2 hours to my dealer to change oil and check unit.
This year rather busy, so I,m doing it myself.
So I called General Pump and they said I can just use 30W non detergent oil, and that the pump holds 40 ounces.

Questions;
I took the plug out and it coming out rather slow, is that normal?
The oil is red in color, I am not sure yet what the Shell W30 is, does that matter?
When checking the dip stick where should the oil line be, at the notch on the stick?

Thanks

If you're draining it cold it is normal for it to be slow, especially in cooler weather. You could have run the machine a few minutes to warm it up a bit, but as long as you drain it out it really doesn't matter. I always buy either the oil recommended by the pump manufacturer or the machine's manufacturer. I honestly can't say whether or not it's any better than a plain old 30 weight non-detergent, but since I'm not changing it that often anyway I always opt for "the good stuff'. I'm pretty sure a lot of guys will just buy the regular 30W non-detergent. As far as filling it you should have it pretty much dead center of the sight glass on the pump. It's almost dummy proof. :) A little over won't hurt, but I always shoot for dead center. That must be a HUGE pump if it takes 40 ounces! I think my Comet takes only 12 oz.

You might want to double check this, but I checked to see if General had their own oil and as I suspected they do. If that were my pump I'd go ahead and buy the 2 1/2 gallon jug for 56.00. Just make certain it's suitable for your pump. That will give you a good supply that should last you a good while. It is a 30 W non-detergent. Call either General or Dultmeier to confirm.

I hope we're on the same subject. I have General Triplex water pressure pump(1200 PSI) For about 7 years I have been using non detergent ISO 68 Cat pump oil ( Home depot- $ 8.99 compare to your dealer shop 100% higher price). It's greenish and yes the best time to change oil is after the job, so oil flows freely. Still, you have to be patient, it'll take time to drain.
I'm not sure about shell oil, hopefully someone will chime in...
