<VV> Quaker State "Defy" Oil

[RoboMan91324 at aol.com]

Bob,
 
I use full synthetic in all my vehicles that are broken in.  Usually  Mobil 
1 with the proper additives.  I believe that only the heavier weights  have 
the proper additives these days but I have many cases of old oil I got on a 
 deal.  It doesn't go bad.  When buying for your old cars, ALWAYS make  
sure that the proper additives are in there.  Some manufacturers will  change 
the mix and keep the same basic label with only the starburst  changed.  This 
is especially the case with the private label and off-brand  stuff.  I 
doubt you can go online for most of the private label stuff and  find what is 
actually in it.  At least, I wouldn't trust that it is  up-to-date info.
 
With a new rebuild, there are varied opinions expressed as to what oil or  
series of oils to use.  This mostly has to do with detergent vs.  
non-detergent oils.  I may look into this further for upcoming  rebuilds.  What I have 
done in the past and probably the future, is use  regular "dino" oil with 
proper additives for the break-in period because  synthetic oil is too 
slippery and the break-in takes forever.  Also, "dino:  oil is cheaper and why use 
synthetic oil at a higher price when there is no  technical benefit?  Once 
the break-in is complete, I switch to synthetic  oil.
