Mobil1 10w-30 - 4000 miles - 2005 Subaru WRX 2.0L Turbo

[FD777]

Good results with this oil. Used the Subaru OEM filter (Tokyo Roki - 15208AA100).

Onto the nitty gritty:
I drive the car moderately. I ALWAYS let her warm-up. ~3k RPM shifts when the she's cold and ~4k RPM shifts when she's warm. The car see's redline more than enough

Car averages two 7-mile city trips on weekdays and 30-50 mile highway trips on the weekends.

I'm trying out GC (German Castrol) now, so we'll see how it goes.

EQUIPMENT MAKE: Subaru OIL USE INTERVAL: 4,000 Miles

EQUIPMENT MODEL: 2.0L Turbo OIL TYPE & GRADE: Mobil 1 10W/30 (Gas)

FUEL TYPE: Gasoline (Unleaded) MAKE-UP OIL ADDED: 0.5 qts



These 2.0L Subarus are nice wearing types and yours is not the exception. Universal

averages show typical wear metals for an oil from this type engine after about 4,745 miles run on the

oil. Your oil was in use just short of those miles, and we found wear generally at better than average

levels and in the correct balance to show normal mechanical parts. Air and oil filtration appear normal.

This was 10W/30 engine oil with no gas moisture or anti-freeze in it. The TBN for this oil was 4.7, still

plenty high. Try 5,000 miles for the next sample. Wear will stay normal.

Looks great. You don't even have the slight iron elevation that M1 sometimes allows. GC will probably do fine, but I wouldn't worry about it. The easy-to-find stuff looks like it will do just fine the way you use it.

 

[SubLGT]

Is this standard M1, or the EP version?

 

[FD777]

I used the standard M1.
The only thing I'm slightly concerned about is the Flash Point. It's still above the recommended value. At this point, I'm not even sure "what" the flash point tells me. I'll have to do more searching...

The first post looks fine in Firefox, but not for Internet Explorer. Here's a re-formatted version for IE users:

No cause for concern. Acceptable value should be 365 or higher.

Yep, those are typical WRX flashpoint values IIRC.
