Hi All Well Im finally a 503 supporter.... I was wondering if their has been found a good

  replacement Oil for the Penzoil Air Cool stuff... I read it was coming off the shelf soon..

  I have about 6 pints that the previous 503 owner handed down to me...

  

 

  

 

  Has a good alternative been found and Will it blend well with what's already in the

  Oil tank???

  

 

  Thanks

Well now you have opened a can of worms. Oil , I  too am a fan of the 503. I have only ever used Castrol super TT. That's a  mineral oil.On engine pull downs I have only ever found some gumming up of the  top ring after 100+ hours.I have been told of the  same on just about  any oil you care to mention. Fly behind what ever oil you sleep easy with. I  will stay with the mineral stuff that has not given me any trouble. I am told  the simple thing is that synthetics have good lubrication properties' and  minerals have good adhesion properties  .So if you are using the engine a  lot then go synthetic if not then go mineral .The simple rule that I use is  the price . The engine will need overhauled before 1000 hours ,you can use a  really expensive oil or cheaper mineral one . If you use a really expensive  synthetic you may find over the life of the engine you have spent more that a  new engine or what an earlier overhaul would have cost on a cheaper oil. >From my  point of view if the oil meets the manufacturers specifications then I will  happily fly with it .

 Blending oils . Now if you pre mix your fuel then I  have no problem with blending, if you have a self lube system then I would  defiantly not blend. Now I cant supply any facts for my thinking here except  that I have being playing around with outboard motors for many years and that's  the rules that apply to them. There has been the odd time that trying to blend  different oils in a self oiler has resulted in the oil congealing and not  passing through the oil pump correctly resulting in damage to the  engine.Pennzoil is not a biggy in this part of the world . There are those that  sing its virtues ,but I personally have seen no great advantages of using it  over other brands.It may well be a good product but it is also very expensive ,  in my opinion not value for money.It may be more reasonably priced in your part  of the world so worth considering.

  

 Regards
