The newer oils do NOT have the zinc additives that was used in the past. Unless you have upgraded your engines internals, then you need to consider the wear on the camshaft and lifters that is not being protected as they were. There are additives on the market that makes up for the missing chemicals in your oil, but it is pricey. Just something to think about....
