I apologize if a similar thread has been made previously, I haven't been able to find one.
1. What kind of vehicle do you have
09 Subaru WRX, stock
71,000 Miles
2. What does your owner's manual says -- not just viscosity, but certifications (look for acronyms like API SM, ILSAC GF-4, etc.) and change intervals as well
ILSAC GF-4 or API classification SM
5w-30 or 5w-40, the manual states 5w-30 is preferred.
The manual doesn't seem to give a change interval
3. Where Do you live
South FL, it gets hot here, it's not rare to see weather in the hundreds over the summer
4. How do you drive (easy? hard? fast? slow?)
I drive pretty hard when possible, but most of my commute is on the interstate, where I tend to go easier, so take that as you will
5. What your daily drive is like (short trips? long trips? city? highway?)
Daily, I drive about 3/4 highway 1/4 city, about 30 miles. Highway speeds are typically 75-80ish, backups/standstill traffic are kinda rare, but do happen.
In general, I am not scared of putting miles on the car, I've been known to take some pretty long trips over the weekend. Normally, these are more of a 50/50 highway/city ratio.
Additionally, over the summer, I may do 1-2 very long road trips.
So call it a medium to long trip on average I guess.
6. Whether your car has any known problems
Not at the moment.
7. Preferences
I would prefer a synthetic oil, unless someone has a good argument otherwise
Price is not really a factor, but I'm not looking for oil infused with gold
I don't have a preference over store bought or ordered online
I've heard good things about Rotella t6 5w-40, any word on that?
