I use Shell Rotella T and get 14 K between changes by taking oil samples and going by Blackstone Oil Analysis. Used them since 1980s even on airplanes. Synthetic oils are a rip, if they weren't the FAA would approve them for use in Airplane Recips.

Is it better: Cons:
Cost is twice as much as conventional oil per quart. However it lasts longer, so the actual cost increase is closer to 50 - 60 percent.
Flows easily, therefore not recommend for use on high mileage engines; nor do I recommend using it in new engines during the break-in period because it is so slippery and dramatically limits the wearing of new mating parts within the engine. This initial wearing of parts is what makes for proper engine break-in, sealing of piston rings, mating of camshafts and lifters, etc.
