Did you ever notice that most of the people advocating 3000 mile oil changes are the people who make money selling oil?
Exactly! We've had the 3,000 mile thing drilled in our heads for years and it's just not true anymore. The technology with the synthetic oils and the engines these days make it possible to go 10,000 miles and more without any problems.
The last 3 or 4 cars I've bought had oil change intervals somewhere around 7,000 miles in the manual.
Thanks for the excellent post on the oil change for a SRX V6. One question, while did you put 5.5 qts when the manual says 6qts?
When I wrote this how-to, it seems that putting in 5.5 qts would get me to the full mark on the dip stick. Being that the car was fairly new, I didn't want to risk over-oiling. Nowadays, for the sake of convenience (Mobile1 comes in a 6-pack), I put in 6 qts. The oil level on the dip stick shows about a centimeter over the full mark, but it doesn't seem to do any harm.
I have a question on oil filters (Re N*V8). I note that the Mobil 1 brand filters seem to be hard to locate (and cost about double that of many others such as ACDelco - what my Cad dealer installed - Fram, Puralator, Pennzoil, etc). Does anyone have facts or suggestions on filters and are filters different for synthetic vs regular oils?? Thanks in advance.

The filter you use is not dependent on the type of oil you use. That said, there are enormous differences in filters on the market. In general, there are paper filters, synthetic blend filters (primarily cellulose, synthetic and glass blend media) and full synthetic filters. Their cost varies as much as their ability to filtrate and flow. Another factor is the quality of the construction.
Again, in general, a filter that filters well, will not flow well. But last year AMSOIL, in partnership with Donaldson and Wix, developed and released a new line of full synthetic air and oil filters that not only filter extremely well, they don't do it at the cost of flow. I now use these in all my vehicles: AMSOIL Ea Oil Filter AMSOIL Ea Air Filter
