Default Re: Oil FAQ: Read if you want more information on oil, oil filters, and oil changes!

Great FAQ!

What about extended oil changes when using synthetics? Extended drain intervals are possible with synthetic oils. To find out at what interval your oil needs to be changed, you need to institute a system of oil analysis. Blackstone Labs provides analysis services to help you determine your oil change interval.
I would quibble with this a bit. Subaru manuals say synthetics are OK to use, but should still be changed at the regular intervals. Given that statement, I decided to stick with dino. (and the fact that I do not drive my car that hard--most of its miles are highway cruising)

"dino" for those like me that took a while to figure it out is short for "dinosaur" ie fossil fuel. (sometime misspelled "dyno")
