Deposit control has many factors, including the choice of oil. It's not unusual to see 10K oil changes with minimal deposits when using quality synthetics. But one factor constantly ignored is that contaminates and microparticulates build up in the oil. Unburned fuel and combustion byproducts get past the piston rings, and into the oil. At which point much of the unburned fuel evaporates, leaving behind a small, non volatile components of the fuel. It accumulates, mile after mile, and it's not oil, and it's not fuel. The combustion byproducts include micro particulates that are instrumental in wearing the various timing and balancer chains.
The choice of a quality synthetic oil, coupled with a 5000 mile oil change interval is a great way ensure you are not shortchanging the life of your engine. Unless you know for a fact that your particular model engine is not prone to rapid timing chain or balancer chain wear, and you know that it's unlikely to have oil consumption issues from clogged piston oil ring drain holes, or poor oil ring performance.... Or any number of other problems that so often crop up in modern engines, from sludge to cam wear.... (Remember many GM, Toyota, Ford, BMW, VW and other brands have these known issues)
