We need interim service (oil & filter change) due to harsher conditions.

True Bob, but after the motor gets run in if you use really high quality synthetic oil you can go 15,000k just that type oil is not cheap, also all synthetic oil is not the same some are only part synthetic, i'm talking about full synthetic. but heat kill's oil! no mater if it is mineral or synthetic heat is the killer. Dazz would be ok with 15,000 interval, and here in winter might be ok if they use good oil but each dealer use different oil as i've seen that already. but that is not a bad thing as look at MB & VW they tell you you have to use the one brand oil or void warranty and that one brand has its price inflated, and i don't beleave the reasoning they use.
cheers
ps Bob i like to buy my own oil and supply it to the dealer to be used in my car or truck just so i know what it has in the motor. so i get what ever oil meets there requirement, this system has always worked for me and i've had some high mileage trouble free motors over the years.
cheers
