Royal Purple Oil
Will the zinc in Royal Purple affect the cat convertors on a 13 GS C-6, The oil is 5-30 weight and I have 12 quarts that was won at a car show.

in another car. Why would the zinc hurt? I believe the zinc is just an additive for older cars in the 60's and 70's. I don't see how it could hurt your car.

Running an oil with a high zinc content will aid in the overall lubrication of internals. I hear of people running Royal Purple in built engines all the time. I'm not too familiar with it, so I can't advise for or against it. However, people buy additives such as Lucas solely for the zinc content, I'd imagine it couldn't possibly hurt your car in any way if you ran RP.

I wouldn't worry about it at all. Check it occasionally to make sure it's not burning excessive oil. If it is then go back to Mobil 1 and use the free oil
